Existing Project Not Showing Installed iOS 26 Simulator (New Projects Work Fine)
Hello everyone, I'm encountering a frustrating issue with Xcode 26 and the iOS Simulator selection, and I'd appreciate any insight from the community. Problem Overview I have updated my Xcode to version 26.0. I have successfully installed the iOS 26 SDK and the iOS 26 Simulator runtime via Xcode's component settings. However, when I open an older, existing project, the device selection dropdown menu does not list the iOS 26 simulator. I can only select older versions, such as my locally installed iOS 18.6 simulator. Key Finding (Diagnosis) New Project Test: When I create a brand new Xcode project, the iOS 26 simulator is correctly available and runs as expected. Conclusion: This strongly suggests the issue lies with a specific configuration setting in the existing (old) project, rather than the Xcode installation itself. Troubleshooting Steps Taken I suspect a project-level configuration is somehow blocking the display of the new simulator. I've already checked: General -> Deployment Target: This is set to an older version, but theoretically shouldn't hide the simulator list. Build Settings -> Base SDK: This is set to the latest iOS SDK. Has anyone else experienced this behavior when upgrading projects to support iOS 26? What specific configuration files (e.g., .xcodeproj settings, Podfile configurations, or specific Build Settings) should I check to ensure my old project properly recognizes and displays the newly installed iOS 26 simulator? Any pointers or solutions would be greatly appreciated! Thank you.

XCUIDevice.shared.appearance = .dark no longer works when running UI tests via xcodebuild on newer iOS versions
I am seeing a regression with XCUIDevice.shared.appearance = .dark in UI tests that only affects xcodebuild, not Xcode’s UI test runner. Setup • UI tests written using XCTest • Dark mode forced in setUp() using: XCUIDevice.shared.appearance = .dark • Tests target an iOS simulator • Same test target, same scheme Expected behavior The app launches in Dark Mode for UI tests, as it did previously. Actual behavior • When running UI tests from Xcode (Product > Test), Dark Mode is applied correctly. • When running the same UI tests via xcodebuild test, Dark Mode is ignored and the app launches in Light Mode. • No test failures, no warnings, no logs indicating the appearance override was skipped. Regression details • This used to work on older iOS versions when running via xcodebuild. • The regression appears after updating iOS simulators (exact version boundary still unclear). • No relevant changes were made to the test code, scheme, or CI configuration. • xcodebuild otherwise launches and runs UI tests normally. Notes • The issue is specific to XCUIDevice.shared.appearance. • Other UI test functionality behaves as expected. • This makes CI results inconsistent with local Xcode runs and breaks visual assumptions in snapshot and layout-based tests. Question Is this a known regression or an intentional behavior change in recent iOS / Xcode versions? If intentional, what is the supported way to reliably force Dark Mode in UI tests when running via xcodebuild? This currently makes xcodebuild-based CI UI testing unreliable compared to Xcode’s test runner.

How does one figure out the Team ID for their Personal Team
I can find the Team ID for a registered development account by going to:developer.apple.com > Account > Membership > Team IDI'm sure that a similar ID exists for the Personal Team. If I select my personal team in xcode and then open MyProject.xcodeproj > project.pbxproj, I can find said ID by looking for DEVELOPMENT_TEAM. But this is a rather hacky way to find my personal team ID. Are there other simpler ways to find it?

Xcode 26.1 Simulator download fails with DVTDownloadableErrorDomain code 41 and code 49 on macOS 26.1
I'm trying to download an iOS Simulator runtime in Xcode 26.2 or 26.1 on macOS 26.1, but the download keeps failing with the following error: Download failed. Domain: DVTDownloadableErrorDomain Code: 41 Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({ RequestedBuild = 23C54;}) Domain: DVTDownloadsUtilitiesErrorDomain. Code: -1. Download failed due to a bad URL. (Catalog download for com.apple.MobileAsset.iOSSimulatorRuntime) Domain: com.apple.MobileAssetError.Download Code: 49 User Info: {checkConfiguration = 1;} macOS & Xcode Info: macOS Version: 26.1 (Build 25B78) Xcode Version: 26.2 (24553) (Build 17C52) What I've tried so far: Formatted my Mac and reinstalled Xcode multiple times. Completely deleted Xcode and its related files several times (/Applications/Xcode.app, caches, preferences). Tried different internet connections from multiple locations. Checked Apple servers and verified network. Attempted downloading other simulator runtimes (fail). but download fails immediately with DVTDownloadableErrorDomain Code 41 and bad URL error. Question: How can I fix the simulator download issue in Xcode 26.2 on macOS 26.1? Is there a known workaround for the bad URL / catalog download error?

FileProvider fails to trigger re-enumeration
I'm working on a FileProvider which allows access to encrypted files in Dropbox; I can successfully read and present the decrypted files, so I know it's basically working. But I'm having problems getting FileProvider to re-enumerate a folder when its encryption status changes. When the FileProvider receives an update notification saying a folder is now encrypted, I use signalEnumerator to re-enumerate the folder: FileProviderExtension.manager?.signalEnumerator(for: existingItem.itemIdentifier, completionHandler: { (ourError : Error?) -> Void in       if let ourError = ourError {           log("notifyCallback: mount / unmount failed re-enumeration: \(ourError)")       } else {           log("notifyCallback: mount / unmount signalled re-enumeration; pending")       } }) The log reports that the re-enumeration is pending... but as far as I can tell, neither enumerateItems nor enumerateChanges is called on the folder's item unless a Finder window is actually open for that folder. This means that, when an app other than Finder tries to access the files through the filesystem, it doesn't see the updated set of filenames. (For further reference: I've added code to both enumerateItems and enumerateChanges, so that if the call has been triggered by a recent folder-encryption notification, it retrieves a complete set of items from the Dropbox folder. If a retrieved file has an encrypted filename, it reports it as a modified item and returns its filename in-clear; if the filename isn't encrypted, it doesn't return the item (for enumerateItems) or returns it as a deleted item (for enumerateChanges). This approach seems to work successfully for listing folders with a constant state; it's only if the user encrypts / decrypts a folder without currently having a Finder window open inside that folder that I'm not seeing a refresh.) Any advice on how I can force a re-enumeration without a Finder window currently being displayed?

XCode 12 - Can't login to Github without Access Token???
Hey, so I wanted to pull from the Github project repository and XCode asked me login again. Forgot my password so I tried a wrong one and now it keeps asking for my Username and Access token, when I actually just want to login with my password. Doesn't let me choose between the too, not even when adding the account through preferences. Anyone know how to just login with password and the reason for this -pardon me- absolutely idiotic choice of not letting the user choose?

Under Xcode 26 beta 3, how to support new glass icons for iOS 26 and old icons for iOS 18?
I know there are several existing threads on this topic but things keep changing. The release notes for Xcode 26 beta 3 have the following statements for a couple of resolved issues: Asset Catalog Fixed: Unable to set Icon Composer icon as alternate iOS icon (153305178) (FB18025356) Icon Composer Fixed: Icon Composer icons back deploy to older versions of iOS, macOS, and watchOS with inconsistent rendering. (152258860) I had a working solution under beta 1 and beta 2 for both of these. But under beta 3, I am now seeing the new glass icons for my app when running on a simulated iOS 18 device. This is happening for both the main app icon and any alternates. This contradicts the statement that beta 3 fixes this issue. There is no documentation (that I can find) describing how you are supposed to support old icons for iOS 18 and new glass icons for iOS 26. There is no documentation for how to support alternate glass icons for iOS 26. What I'm doing at the moment (that worked before beta 3) was to have the normal iOS 18 app icons in the Asset catalog and to have the new glass icons added to the project. The filenames for the glass .icon files have the same name as the app icons in the Assets catalog. This worked under beta 1 and beta 2. And despite the Xcode 26 beta 3 release notes stating that Icon Composer icons no longer back deploy to iOS 18, I'm seeing the opposite. Beta 3 now does the opposite of that statement. Does anyone have a working solution that supports old iOS 18 app icons and new iOS 26 glass icons using Xcode 26 beta 3? Note, all of my testing is with simulated iOS devices and I'm running Xcode 26 beta 3 under macOS 15.5. Maybe that's an issue?

Application Hangs with Nested LazyVStack When Accessibility Inspector is Active
Description I've encountered a consistent hang/freeze issue in SwiftUI applications when using nested LazyVStack containers with Accessibility Inspector (simulator) or VoiceOver (physical device) enabled. The application becomes completely unresponsive and must be force-quit. Importantly, this hang occurs in a minimal SwiftUI project with no third-party dependencies, suggesting this is a framework-level issue with the interaction between SwiftUI's lazy view lifecycle and the accessibility system. Reproduction Steps I've created a minimal reproduction project available here: https://github.com/pendo-io/SwiftUI_Hang_Reproduction To Reproduce: Create a SwiftUI view with the following nested LazyVStack structure: struct NestedLazyVStackView: View { @State private var outerSections: [Int] = [] @State private var innerRows: [Int: [Int]] = [:] var body: some View { ScrollView { LazyVStack(alignment: .leading, spacing: 24) { ForEach(outerSections, id: \.self) { section in VStack(alignment: .leading, spacing: 8) { Text("Section #\(section)") // Nested LazyVStack LazyVStack(alignment: .leading, spacing: 2) { ForEach(innerRows[section] ?? [], id: \.self) { row in Text("Section #\(section) - Row #\(row)") .onAppear { // Load more data when row appears loadMoreInner(section: section) } } } } .onAppear { // Load more sections when section appears loadMoreOuter() } } } } } } Enable Accessibility Inspector in iOS Simulator: Xcode → Open Developer Tool → Accessibility Inspector Select your running simulator Enable Inspection mode (eye icon) Navigate to the view and start scrolling Result: The application hangs and becomes unresponsive within a few seconds of scrolling Expected Behavior The application should remain responsive when Accessibility Inspector or VoiceOver is enabled, allowing users to scroll through nested lazy containers without freezing. Actual Behavior The application freezes/hangs completely CPU usage may spike The app must be force-quit to recover The hang occurs consistently and is reproducible Workaround 1: Replace inner LazyVStack with VStack LazyVStack { ForEach(...) { section in VStack { // ← Changed from LazyVStack ForEach(...) { row in ... } } } } Workaround 2: Embed in TabView TabView { NavigationStack { NestedLazyVStackView() // ← Same nested structure, but no hang } .tabItem { ... } } Interestingly, wrapping the entire navigation stack in a TabView prevents the hang entirely, even with the nested LazyVStack structure intact. Questions for Apple Is there a known issue with nested LazyVStack containers and accessibility traversal? Why does wrapping the view in a TabView prevent the hang? Are there recommended patterns for using nested lazy containers with accessibility support? Is this a timing issue, a deadlock, or an infinite loop in the accessibility system? Why that happens? Reproduction Project A complete, minimal reproduction project is available at: https://github.com/pendo-io/SwiftUI_Hang_Reproduction

Xcode 26.4.1 Crashes on Launch with Code Signature Invalid on macOS 26.4.1 and All Higher Versions (26.5 / 26.6 beta)
Description Xcode 26.4.1 crashes immediately on launch with a code signature error. The issue exists on macOS 26.4.1 and persists after upgrading to macOS 26.5 (25F5058e) and attempting 26.6 beta. Crash Details: Exception Type: EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid)) Termination Reason: Namespace CODESIGNING, Code 2, Invalid Page Key symbols: dyld3::MachOFile::trieWalk, dyld4::JustInTimeLoader::applyFixups, dyld4::Loader::forEachBindTarget All Steps Tried (All Failed): Fresh reinstall from Mac App Store and .xip from Developer website Multiple sudo xattr -cr + sudo codesign --force --deep --strict --options=runtime --sign - Deleted all Xcode caches, DerivedData, and preferences Tested in a brand new user account (same crash) Downgraded Xcode to older versions macOS remains on 26.4.1 (issue existed here) and upgraded to 26.5 / attempted 26.6 beta — still same crash Refreshed Apple Worldwide Developer Relations certificates Multiple restarts The crash report is identical every time. System Information Model: MacBook Pro (M1 Pro, MacBookPro18,1) macOS: 26.5 (25F5058e) — issue started after upgrade from 26.4.1 Xcode: 26.4.1 (24909.0.3) SIP: Enabled Developer Mode: Enabled Additional Notes Other applications launch normally. This appears to be a system-level compatibility issue introduced in macOS 26.5's stricter code signing validation on mapped files / chained fixups. Request Is there a known workaround? Is Apple preparing a fix in a future macOS 26.5 patch or Xcode update? What additional information would help? Thank you!

How to delete iOS simulator runtimes?
There are multiple iOS simulator runtimes located at /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime which I don't need. I tried the following approaches to delete them but not working. Xcode > Settings > Components > Delete (It can delete some but not all of them) xcrun simctl runtime list (It doesn't show the old runtimes) sudo rm (Operation not permitted) sudo rm -rf cc1f035290d244fca4f74d9d243fcd02d2876c27.asset Password: rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData/096-69246-684.dmg: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/Info.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/version.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset: Operation not permitted I have two questions: Why "xcrun simctl runtime list" is unable to list some old runtimes? How to delete them?

Xcode 26.4: xcodebuild test crashes on iOS 15.2 Simulators before XCTest bootstrap due to ResultDataPublisher missing Foundation.URLRequest.httpMethod symbol
I’m seeing a crash when running XCTest on iOS 15.2 Simulators with Xcode 26.4. The test bundle never starts. xctest crashes before establishing the XCTest connection. This appears to be a regression from Xcode 26.2. The same test flow worked with Xcode 26.2, but crashes with Xcode 26.4. This does not appear to be caused by my app or package code. I can reproduce it with a minimal Swift Package that only imports Foundation and has one XCTest case using URLRequest.httpMethod. Environment: Xcode with failure: 26.4 Xcode that worked: 26.2 macOS: 26.2 Destinations tested: iPhone SE (2nd generation), iOS 15.2 Simulator iPad mini (6th generation), iOS 15.2 Simulator Test command: xcodebuild test Swift Package deployment target: iOS 15.2 Swift tools version: 6.1 Minimal reproduction package: Package.swift // swift-tools-version:6.1 import PackageDescription let package = Package( name: "FoundationOnlyRepro", platforms: [.iOS("15.2")], products: [ .library( name: "FoundationOnlyRepro", targets: ["FoundationOnlyRepro"] ) ], targets: [ .target(name: "FoundationOnlyRepro"), .testTarget( name: "FoundationOnlyReproTests", dependencies: ["FoundationOnlyRepro"] ) ], swiftLanguageModes: [.v6] ) Sources/FoundationOnlyRepro/FoundationOnlyRepro.swift import Foundation public struct FoundationOnlyRepro { public init() {} public func makeRequest() -> URLRequest { var request = URLRequest(url: URL(string: "https://example.invalid")!) request.httpMethod = "GET" return request } } Tests/FoundationOnlyReproTests/FoundationOnlyReproTests.swift import XCTest import Foundation @testable import FoundationOnlyRepro final class FoundationOnlyReproTests: XCTestCase { func testURLRequestHTTPMethod() { let request = FoundationOnlyRepro().makeRequest() XCTAssertEqual(request.httpMethod, "GET") } } Command used: xcodebuild test \ -scheme FoundationOnlyRepro \ -destination 'platform=iOS Simulator,name=iPhone SE (2nd generation),OS=15.2' \ -derivedDataPath /tmp/rdp-dd \ -quiet The same kind of crash also occurs when using an iPad mini (6th generation) iOS 15.2 Simulator destination. Result: Testing failed: xctest (...) encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal abrt before establishing connection.)) ** TEST FAILED ** The diagnostic stderr shows: dyld[28688]: Symbol not found: _$s10Foundation10URLRequestV10httpMethodSSSgvs Referenced from: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/PrivateFrameworks/ResultDataPublisher.framework/ ResultDataPublisher Expected in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.2.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Foundation.framework/Foundation Demangling the missing symbol: xcrun swift-demangle '_$s10Foundation10URLRequestV10httpMethodSSSgvs' Output: Foundation.URLRequest.httpMethod.setter : Swift.String? I also checked the iOS 15.2 simulator runtime. The symbol appears to exist in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.2.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift/libswiftFoundation.dylib but ResultDataPublisher.framework appears to be resolving it from: .../System/Library/Frameworks/Foundation.framework/Foundation This suggests the crash is in Xcode’s XCTest/result publishing infrastructure, not in the app/test bundle. Questions: Is Xcode 26.4 + iOS 15.2 Simulator + xcodebuild test expected to be supported? Is there a supported workaround to disable or avoid ResultDataPublisher.framework for command-line XCTest runs?

Xcode cloud time out issue
We are getting following error in xcode cloud "The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes" We are using following env to create a build. Xcode: 14.2 Macos: Ventura 13.2.1 We didn't face any issue in Ventura 13.2.0 and we are seeing this issue in our first build using ventura 13.2.1. The difference I see between successful and failure build, I don't see "Discovering Swift tasks after 'Compiling { list of swift file " in a failed build. I see compiling { list of swift file } and end of the compilation, the build is failing.

As soon as I run the app in debug the breakpoints are disabled
After updating my system to macOS Tahoe 26.1 and Xcode 26.1, all breakpoints in my project fail to work. When I run the application in Debug mode, any enabled breakpoint (blue) immediately becomes disabled (grayed out) the moment the app launches. The application runs, but the debugger never stops. This issue occurs in any location, including in the application's init() method, which should always be hit. This behavior suggests that the LLDB debugger is failing to attach to the process at launch or is being instructed not to enable breakpoints. System Configuration: Mac Model: MacBook Pro 14" (2021), Apple M1 Pro macOS Version: Tahoe 26.1 Xcode Version: 26.1 Project Type: SwiftUI App for macOS Troubleshooting Steps Performed (All Unsuccessful): We have performed an extensive series of troubleshooting steps to resolve the issue, none of which have worked. These steps include: Basic Project Cleaning: Cleaned the build folder (Product > Clean Build Folder). Deleted the entire DerivedData directory. Deleted the project's xcuserdata folder. Xcode & System Procedures: Restarted Xcode multiple times. Rebooted the Mac multiple times. Reinstalled Xcode Command Line Tools using xcode-select --install. Reset the Xcode path using sudo xcode-select --reset and sudo xcode-select -s /Applications/Xcode.app/Contents/Developer. Forced an update of the system's shared cache with xcrun simctl runtime dyld_shared_cache update --all. Project Build Settings Verification (for Debug configuration): Build Configuration: Verified that the "Run" scheme is set to Debug. Optimization Level: Confirmed it is set to No Optimization [-O0]. Debug Information Format: Confirmed it is set to DWARF with dSYM File. Strip Swift Symbols: Confirmed it is set to No. (This was a new setting noticed after the Xcode update). Enable Hardened Runtime: Attempted setting this to both Yes and No. The issue persists in both cases. Validate Workspace: Confirmed it is set to Yes. Code Signing: Verified that "Automatically manage signing" is enabled with a valid team. Manually deleted and re-created the "Apple Development" certificates via Xcode's Accounts settings. Direct LLDB Testing: Created a ~/.lldbinit file. Using breakpoint list, confirmed that LLDB starts with "No breakpoints currently set," indicating that Xcode is likely not passing the breakpoints to the debugger. Using settings set target.process.stop-on-entry true, confirmed that the app still does not stop on entry, suggesting the debugger is failing to attach to the process at all. Conclusion: Given that all standard and advanced troubleshooting steps have failed, and the issue started immediately after updating both macOS and Xcode to a non-public release (Tahoe 26.1 / Xcode 26.1), this appears to be a regression or a bug in the new development environment. The failure of stop-on-entry strongly suggests a fundamental issue with the debugger attachment process on this specific OS and Xcode combination.

XCode problem
Right now, I am trying the tutorial for SwiftUI from the Apple Developer Program inside of Xcode, but I encountered a problem. Inside of the selectable canvas mode in Xcode, I wanted to command-control-click the element (in this case, a text) to bring up the editing popover and select "Show SwiftUI Inspector." For some reason, on the popover menu, the only option was "Embed." I only wanted the menu point Show SwiftUI Inspector, and I also tried the shortcut Ctrl+Option, but nothing worked. Now is there another method to get to this menu? Or can you help me with that? Noah

FileProvider fails to trigger re-enumeration
I'm working on a FileProvider which allows access to encrypted files in Dropbox; I can successfully read and present the decrypted files, so I know it's basically working. But I'm having problems getting FileProvider to re-enumerate a folder when its encryption status changes. When the FileProvider receives an update notification saying a folder is now encrypted, I use signalEnumerator to re-enumerate the folder: FileProviderExtension.manager?.signalEnumerator(for: existingItem.itemIdentifier, completionHandler: { (ourError : Error?) -> Void in       if let ourError = ourError {           log("notifyCallback: mount / unmount failed re-enumeration: \(ourError)")       } else {           log("notifyCallback: mount / unmount signalled re-enumeration; pending")       } }) The log reports that the re-enumeration is pending... but as far as I can tell, neither enumerateItems nor enumerateChanges is called on the folder's item unless a Finder window is actually open for that folder. This means that, when an app other than Finder tries to access the files through the filesystem, it doesn't see the updated set of filenames. (For further reference: I've added code to both enumerateItems and enumerateChanges, so that if the call has been triggered by a recent folder-encryption notification, it retrieves a complete set of items from the Dropbox folder. If a retrieved file has an encrypted filename, it reports it as a modified item and returns its filename in-clear; if the filename isn't encrypted, it doesn't return the item (for enumerateItems) or returns it as a deleted item (for enumerateChanges). This approach seems to work successfully for listing folders with a constant state; it's only if the user encrypts / decrypts a folder without currently having a Finder window open inside that folder that I'm not seeing a refresh.) Any advice on how I can force a re-enumeration without a Finder window currently being displayed?

XCode 12 - Can't login to Github without Access Token???
Hey, so I wanted to pull from the Github project repository and XCode asked me login again. Forgot my password so I tried a wrong one and now it keeps asking for my Username and Access token, when I actually just want to login with my password. Doesn't let me choose between the too, not even when adding the account through preferences. Anyone know how to just login with password and the reason for this -pardon me- absolutely idiotic choice of not letting the user choose?

XCode crashing in VIM Mode while deleting the complete line with double tap of "d"
I have been using Xcode Version 26.1.1 on macOS Tahoe Version 26.1. In VIM mode, whenever I quickly tap d twice, to delete the complete line, most of the time Xcode crashes. Is anyone else facing this issue? Should I move to any older version of Xcode or any other solve for this?

Under Xcode 26 beta 3, how to support new glass icons for iOS 26 and old icons for iOS 18?
I know there are several existing threads on this topic but things keep changing. The release notes for Xcode 26 beta 3 have the following statements for a couple of resolved issues: Asset Catalog Fixed: Unable to set Icon Composer icon as alternate iOS icon (153305178) (FB18025356) Icon Composer Fixed: Icon Composer icons back deploy to older versions of iOS, macOS, and watchOS with inconsistent rendering. (152258860) I had a working solution under beta 1 and beta 2 for both of these. But under beta 3, I am now seeing the new glass icons for my app when running on a simulated iOS 18 device. This is happening for both the main app icon and any alternates. This contradicts the statement that beta 3 fixes this issue. There is no documentation (that I can find) describing how you are supposed to support old icons for iOS 18 and new glass icons for iOS 26. There is no documentation for how to support alternate glass icons for iOS 26. What I'm doing at the moment (that worked before beta 3) was to have the normal iOS 18 app icons in the Asset catalog and to have the new glass icons added to the project. The filenames for the glass .icon files have the same name as the app icons in the Assets catalog. This worked under beta 1 and beta 2. And despite the Xcode 26 beta 3 release notes stating that Icon Composer icons no longer back deploy to iOS 18, I'm seeing the opposite. Beta 3 now does the opposite of that statement. Does anyone have a working solution that supports old iOS 18 app icons and new iOS 26 glass icons using Xcode 26 beta 3? Note, all of my testing is with simulated iOS devices and I'm running Xcode 26 beta 3 under macOS 15.5. Maybe that's an issue?

Application Hangs with Nested LazyVStack When Accessibility Inspector is Active
Description I've encountered a consistent hang/freeze issue in SwiftUI applications when using nested LazyVStack containers with Accessibility Inspector (simulator) or VoiceOver (physical device) enabled. The application becomes completely unresponsive and must be force-quit. Importantly, this hang occurs in a minimal SwiftUI project with no third-party dependencies, suggesting this is a framework-level issue with the interaction between SwiftUI's lazy view lifecycle and the accessibility system. Reproduction Steps I've created a minimal reproduction project available here: https://github.com/pendo-io/SwiftUI_Hang_Reproduction To Reproduce: Create a SwiftUI view with the following nested LazyVStack structure: struct NestedLazyVStackView: View { @State private var outerSections: [Int] = [] @State private var innerRows: [Int: [Int]] = [:] var body: some View { ScrollView { LazyVStack(alignment: .leading, spacing: 24) { ForEach(outerSections, id: \.self) { section in VStack(alignment: .leading, spacing: 8) { Text("Section #\(section)") // Nested LazyVStack LazyVStack(alignment: .leading, spacing: 2) { ForEach(innerRows[section] ?? [], id: \.self) { row in Text("Section #\(section) - Row #\(row)") .onAppear { // Load more data when row appears loadMoreInner(section: section) } } } } .onAppear { // Load more sections when section appears loadMoreOuter() } } } } } } Enable Accessibility Inspector in iOS Simulator: Xcode → Open Developer Tool → Accessibility Inspector Select your running simulator Enable Inspection mode (eye icon) Navigate to the view and start scrolling Result: The application hangs and becomes unresponsive within a few seconds of scrolling Expected Behavior The application should remain responsive when Accessibility Inspector or VoiceOver is enabled, allowing users to scroll through nested lazy containers without freezing. Actual Behavior The application freezes/hangs completely CPU usage may spike The app must be force-quit to recover The hang occurs consistently and is reproducible Workaround 1: Replace inner LazyVStack with VStack LazyVStack { ForEach(...) { section in VStack { // ← Changed from LazyVStack ForEach(...) { row in ... } } } } Workaround 2: Embed in TabView TabView { NavigationStack { NestedLazyVStackView() // ← Same nested structure, but no hang } .tabItem { ... } } Interestingly, wrapping the entire navigation stack in a TabView prevents the hang entirely, even with the nested LazyVStack structure intact. Questions for Apple Is there a known issue with nested LazyVStack containers and accessibility traversal? Why does wrapping the view in a TabView prevent the hang? Are there recommended patterns for using nested lazy containers with accessibility support? Is this a timing issue, a deadlock, or an infinite loop in the accessibility system? Why that happens? Reproduction Project A complete, minimal reproduction project is available at: https://github.com/pendo-io/SwiftUI_Hang_Reproduction

Xcode 26.4.1 Crashes on Launch with Code Signature Invalid on macOS 26.4.1 and All Higher Versions (26.5 / 26.6 beta)
Description Xcode 26.4.1 crashes immediately on launch with a code signature error. The issue exists on macOS 26.4.1 and persists after upgrading to macOS 26.5 (25F5058e) and attempting 26.6 beta. Crash Details: Exception Type: EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid)) Termination Reason: Namespace CODESIGNING, Code 2, Invalid Page Key symbols: dyld3::MachOFile::trieWalk, dyld4::JustInTimeLoader::applyFixups, dyld4::Loader::forEachBindTarget All Steps Tried (All Failed): Fresh reinstall from Mac App Store and .xip from Developer website Multiple sudo xattr -cr + sudo codesign --force --deep --strict --options=runtime --sign - Deleted all Xcode caches, DerivedData, and preferences Tested in a brand new user account (same crash) Downgraded Xcode to older versions macOS remains on 26.4.1 (issue existed here) and upgraded to 26.5 / attempted 26.6 beta — still same crash Refreshed Apple Worldwide Developer Relations certificates Multiple restarts The crash report is identical every time. System Information Model: MacBook Pro (M1 Pro, MacBookPro18,1) macOS: 26.5 (25F5058e) — issue started after upgrade from 26.4.1 Xcode: 26.4.1 (24909.0.3) SIP: Enabled Developer Mode: Enabled Additional Notes Other applications launch normally. This appears to be a system-level compatibility issue introduced in macOS 26.5's stricter code signing validation on mapped files / chained fixups. Request Is there a known workaround? Is Apple preparing a fix in a future macOS 26.5 patch or Xcode update? What additional information would help? Thank you!

How to delete iOS simulator runtimes?
There are multiple iOS simulator runtimes located at /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime which I don't need. I tried the following approaches to delete them but not working. Xcode > Settings > Components > Delete (It can delete some but not all of them) xcrun simctl runtime list (It doesn't show the old runtimes) sudo rm (Operation not permitted) sudo rm -rf cc1f035290d244fca4f74d9d243fcd02d2876c27.asset Password: rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData/096-69246-684.dmg: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/AssetData: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/Info.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset/version.plist: Operation not permitted rm: cc1f035290d244fca4f74d9d243fcd02d2876c27.asset: Operation not permitted I have two questions: Why "xcrun simctl runtime list" is unable to list some old runtimes? How to delete them?

Xcode 26.4: xcodebuild test crashes on iOS 15.2 Simulators before XCTest bootstrap due to ResultDataPublisher missing Foundation.URLRequest.httpMethod symbol
I’m seeing a crash when running XCTest on iOS 15.2 Simulators with Xcode 26.4. The test bundle never starts. xctest crashes before establishing the XCTest connection. This appears to be a regression from Xcode 26.2. The same test flow worked with Xcode 26.2, but crashes with Xcode 26.4. This does not appear to be caused by my app or package code. I can reproduce it with a minimal Swift Package that only imports Foundation and has one XCTest case using URLRequest.httpMethod. Environment: Xcode with failure: 26.4 Xcode that worked: 26.2 macOS: 26.2 Destinations tested: iPhone SE (2nd generation), iOS 15.2 Simulator iPad mini (6th generation), iOS 15.2 Simulator Test command: xcodebuild test Swift Package deployment target: iOS 15.2 Swift tools version: 6.1 Minimal reproduction package: Package.swift // swift-tools-version:6.1 import PackageDescription let package = Package( name: "FoundationOnlyRepro", platforms: [.iOS("15.2")], products: [ .library( name: "FoundationOnlyRepro", targets: ["FoundationOnlyRepro"] ) ], targets: [ .target(name: "FoundationOnlyRepro"), .testTarget( name: "FoundationOnlyReproTests", dependencies: ["FoundationOnlyRepro"] ) ], swiftLanguageModes: [.v6] ) Sources/FoundationOnlyRepro/FoundationOnlyRepro.swift import Foundation public struct FoundationOnlyRepro { public init() {} public func makeRequest() -> URLRequest { var request = URLRequest(url: URL(string: "https://example.invalid")!) request.httpMethod = "GET" return request } } Tests/FoundationOnlyReproTests/FoundationOnlyReproTests.swift import XCTest import Foundation @testable import FoundationOnlyRepro final class FoundationOnlyReproTests: XCTestCase { func testURLRequestHTTPMethod() { let request = FoundationOnlyRepro().makeRequest() XCTAssertEqual(request.httpMethod, "GET") } } Command used: xcodebuild test \ -scheme FoundationOnlyRepro \ -destination 'platform=iOS Simulator,name=iPhone SE (2nd generation),OS=15.2' \ -derivedDataPath /tmp/rdp-dd \ -quiet The same kind of crash also occurs when using an iPad mini (6th generation) iOS 15.2 Simulator destination. Result: Testing failed: xctest (...) encountered an error (Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal abrt before establishing connection.)) ** TEST FAILED ** The diagnostic stderr shows: dyld[28688]: Symbol not found: _$s10Foundation10URLRequestV10httpMethodSSSgvs Referenced from: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Library/PrivateFrameworks/ResultDataPublisher.framework/ ResultDataPublisher Expected in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.2.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/Foundation.framework/Foundation Demangling the missing symbol: xcrun swift-demangle '_$s10Foundation10URLRequestV10httpMethodSSSgvs' Output: Foundation.URLRequest.httpMethod.setter : Swift.String? I also checked the iOS 15.2 simulator runtime. The symbol appears to exist in: /Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 15.2.simruntime/Contents/Resources/RuntimeRoot/usr/lib/swift/libswiftFoundation.dylib but ResultDataPublisher.framework appears to be resolving it from: .../System/Library/Frameworks/Foundation.framework/Foundation This suggests the crash is in Xcode’s XCTest/result publishing infrastructure, not in the app/test bundle. Questions: Is Xcode 26.4 + iOS 15.2 Simulator + xcodebuild test expected to be supported? Is there a supported workaround to disable or avoid ResultDataPublisher.framework for command-line XCTest runs?

Xcode cloud time out issue
We are getting following error in xcode cloud "The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes" We are using following env to create a build. Xcode: 14.2 Macos: Ventura 13.2.1 We didn't face any issue in Ventura 13.2.0 and we are seeing this issue in our first build using ventura 13.2.1. The difference I see between successful and failure build, I don't see "Discovering Swift tasks after 'Compiling { list of swift file " in a failed build. I see compiling { list of swift file } and end of the compilation, the build is failing.

Xcode 26.1 ChatGPT very slow
ChatGPT in Xcode 26.1 is super slow for me, anyone else? The response returns quickly but the preview window takes a few seconds per line. What it used to do in a few seconds on 26.0 now takes tens of minutes. Anyone else running into this and have suggestions? I'm using the minimal setting on a fast internet connection. M2 Pro MBP, macOS 26.1.

As soon as I run the app in debug the breakpoints are disabled
After updating my system to macOS Tahoe 26.1 and Xcode 26.1, all breakpoints in my project fail to work. When I run the application in Debug mode, any enabled breakpoint (blue) immediately becomes disabled (grayed out) the moment the app launches. The application runs, but the debugger never stops. This issue occurs in any location, including in the application's init() method, which should always be hit. This behavior suggests that the LLDB debugger is failing to attach to the process at launch or is being instructed not to enable breakpoints. System Configuration: Mac Model: MacBook Pro 14" (2021), Apple M1 Pro macOS Version: Tahoe 26.1 Xcode Version: 26.1 Project Type: SwiftUI App for macOS Troubleshooting Steps Performed (All Unsuccessful): We have performed an extensive series of troubleshooting steps to resolve the issue, none of which have worked. These steps include: Basic Project Cleaning: Cleaned the build folder (Product > Clean Build Folder). Deleted the entire DerivedData directory. Deleted the project's xcuserdata folder. Xcode & System Procedures: Restarted Xcode multiple times. Rebooted the Mac multiple times. Reinstalled Xcode Command Line Tools using xcode-select --install. Reset the Xcode path using sudo xcode-select --reset and sudo xcode-select -s /Applications/Xcode.app/Contents/Developer. Forced an update of the system's shared cache with xcrun simctl runtime dyld_shared_cache update --all. Project Build Settings Verification (for Debug configuration): Build Configuration: Verified that the "Run" scheme is set to Debug. Optimization Level: Confirmed it is set to No Optimization [-O0]. Debug Information Format: Confirmed it is set to DWARF with dSYM File. Strip Swift Symbols: Confirmed it is set to No. (This was a new setting noticed after the Xcode update). Enable Hardened Runtime: Attempted setting this to both Yes and No. The issue persists in both cases. Validate Workspace: Confirmed it is set to Yes. Code Signing: Verified that "Automatically manage signing" is enabled with a valid team. Manually deleted and re-created the "Apple Development" certificates via Xcode's Accounts settings. Direct LLDB Testing: Created a ~/.lldbinit file. Using breakpoint list, confirmed that LLDB starts with "No breakpoints currently set," indicating that Xcode is likely not passing the breakpoints to the debugger. Using settings set target.process.stop-on-entry true, confirmed that the app still does not stop on entry, suggesting the debugger is failing to attach to the process at all. Conclusion: Given that all standard and advanced troubleshooting steps have failed, and the issue started immediately after updating both macOS and Xcode to a non-public release (Tahoe 26.1 / Xcode 26.1), this appears to be a regression or a bug in the new development environment. The failure of stop-on-entry strongly suggests a fundamental issue with the debugger attachment process on this specific OS and Xcode combination.

Now with Xcode beta (Version 26.0 beta 4 (17A5285i)) I'll be working on a project when the system (Mac mini 2025) suddenly reboots itself. This has been going on since beta 3. I am also running MacOS 26.0 Beta (25A5316i). I have filed a bug report. Is anyone else having this problem? Thanks, Dan Uff

XCode problem
Right now, I am trying the tutorial for SwiftUI from the Apple Developer Program inside of Xcode, but I encountered a problem. Inside of the selectable canvas mode in Xcode, I wanted to command-control-click the element (in this case, a text) to bring up the editing popover and select "Show SwiftUI Inspector." For some reason, on the popover menu, the only option was "Embed." I only wanted the menu point Show SwiftUI Inspector, and I also tried the shortcut Ctrl+Option, but nothing worked. Now is there another method to get to this menu? Or can you help me with that? Noah
