empty dSYM file detected - Xcode 16
Hi , I am currently encountering issues while running a Titanium application using Xcode 16. I would like to request your guidance on resolving the following problems: When running the Titanium app on a real device, I receive the following warning in Xcode and the app does not proceed beyond this point and the app is crashing on launch. warning: (arm64) /Users/Library/Developer/Xcode/DerivedData/Procedures-hamsarmfbtnowbcdocpmydtuafnp/Build/Products/Debug-iphoneos/Procedures.app/Procedures empty dSYM file detected, dSYM was created with an executable with no debug info. Thank you

Ethernet TSO Issues After Sequoia Update
I have a service that has been running on a 3x cluster of headless M1 Mac Studios since Ventura, and before that on headless Mac minis since Monterey. Now, after updating the Studios from Sonoma to Sequoia, response times have slowed to a crawl. For example, generating and sending a 150KB PDF file normally takes around 20 milliseconds. Now it takes over 15 SECONDS! The daemon code didn't change between updates. The issue seems to center around TSO on the ethernet port. Connecting via a port without TSO works as expected. But the 10 GB ethernet port on the Studio has built-in TSO. I've tried to disable TSO using sudo sysctl -w net.inet.tcp.tso=0. This works for an hour or so before the daemon eventually becomes unresponsive. At this point the daemon has to be terminated and restarted. So for now I'm having to use cheap USB-C to Ethernet adapters to connect the Mac Studios. Is there a configuration setting I'm missing for proper TSO in Network Framework?

Xcode JSONDecoder playground fails with 'The LLDB RPC server has crashed.
If I create a playground project that uses a JSONDecoder I get the following error. The LLDB RPC Server has crashed. The crash log is located at ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log. I have raised feedback for this, FB17702087, but I hope that there may be a workaround. The code I am using to try and get this to work is from The Apple Developer Documentation - JSON Decoder var greeting = "JSON Test 3" struct GroceryProduct: Codable { var name: String var points: Int var description: String? } let json = """ { "name": "Durian", "points": 600, "description": "A fruit with a distinctive scent." } """.data(using: .utf8)! let decoder = JSONDecoder() let product = try decoder.decode(GroceryProduct.self, from: json) print(product.name) // Prints "Durian" A screenshot of the playground showing the error The crash log (the file type has been changed to txt as ips file types cannot be selected for upload. lldb-rpc-server-2025-05-28-140832.txt

How can you communicate that a .xcframework is a dependency OF the swift package inside Swift package definition?
I am sort of trying to do the opposite of what others are doing. I have a target called CopyFramework that creates a CopyFramework.framework within my main xcproj file. I set up this target because a specific framework (we can call it Tools.xcframework) is distributed as a binary. That framework file lives within the code. Tools.xcframework is structured like so Tools.xcframework (Coding/testBuild/DynamicToolFrameworks/Tools.xcframework) info.plist ios-arm64/ Tools.xcframework/ Tools (executable file) Tools.bundle Headers/ Info.plist Modules/ Tools.swiftmodule/ arm64-apple-ios.abi.json arm64-apple-ios.private.swiftinterface arm64-apple-ios.swiftdoc arm64-apple-ios.swiftinterface module.modulemap module.private.modulemap PrivateHeaders/ ios-arm64_x86_64-simulator/ When the CopyFramework target is run xcode does a few steps which copy the correct version of this framework to derived data. Process Tools.xcframework (iOS) Coding/testBuild/DynamicToolFrameworks/Tools.xcframework /Library/Developer/Xcode/DerivedData/testBuild-sha/Build/Products/Debug-iphoneos/Tools.framework ios cd /Users/calebkierum/Coding/testBuild builtin-process-xcframework --xcframework Coding/testBuild/DynamicToolFrameworks/Tools.xcframework --platform ios --target-path Library/Developer/Xcode/DerivedData/testBuild-sha/Build/Products/Debug-iphoneos Meaning essentially that the Tools.xcframework for the proper platform is taken from Tools.xcframework/ios-arm64 and copied to Library/Developer/Xcode/DerivedData/testBuild-sha/Build/Products/Debug-iphoneos/Tools.xcframework I am writing a Swift Package that needs to be able to reference the correct Tools.xcframework. I have set it up like so: let package = Package( name: "CoreObjC", platforms: [.iOS(.v17), .macCatalyst(.v17)], products: [ .library(name: "CoreObjC", targets: ["CoreObjC"]), ], dependencies: [ // Does something to here ??? //.package(path: "../testBuild") ], targets: [ .target( name: "CoreObjC", dependencies: [ // Here I would like to be referencing the CopyFramework.framework target within my buildTest.xcproj file .product(name: "CopyFramework", package: /*??? its not in a swift package its a part of an xcproj file*/) ], path: "CoreObjC", publicHeadersPath: "Headers", linkerSettings: [ .linkedFramework("Tools", .when(platforms: [.iOS])), .linkedLibrary("c++") ] ), ], cxxLanguageStandard: CXXLanguageStandard.gnucxx14 ) Now obviously this does not work. I do not know how to communicate to the Package.swift file that the binary dependency is a framework target within my xcproj file. If I do run the target CopyFramework followed by building CoreObjC it works though (so long as you comment out the bits trying to reference CopyFramework). Running the CopyFramework target processes the Tools.xcframework and copies the proper xcframework sub folder to Derived data and the Swift Package build system seems to be able to see it. Is there a way I can get rid of this manual step? Make it so that when I build the CoreObjC target (swift package) that either CopyFramework is run or some other process is run to get the proper xcframework out of Coding/testBuild/DynamicToolFrameworks/Tools.xcframework and into DerivedData? Is it even theoretically possible to have a Swift Package reference a target in a normal xcproj file?

Apple Watch Logs and Debugging
Developing a standalone app for the Apple Watch. Unless I turn off Bluetooth on the paired iPhone, the Apple Watch’s Wi-Fi deactivates every ~30 seconds, which causes the connection to Xcode to drop. How is this supposed to work? I can see my app’s logs in Xcode, but I can’t view any other system logs from the Apple Watch. I tried using the Console app, with the iPhone connected via USB, trusted, etc, but I don't see any system logs. How can I access full system logs? Thanks!

Proper includes into Package.swift
Ok, I have a bit of special problem. I want to use the "Swift Upcoming Feature Flags" in my packages. The problem is that we have quite a lot of Packages in a quite deep tree: at the root of the Package directory there are four dirs: AppA/ AppB/ Shared/ Temporary/ also the packages ExternalLibs and BuildPlugins. Temporary contains Packages that need rework and the other three subdirs each contain the subdirs: Features/ Utilities/ Services/ All in all there are over 100 packages. Now I would like to use definitions like https://github.com/treastrain/swift-upcomingfeatureflags-cheatsheet to use in the Package.swift files. And as you might guess, I do not want to copy those into each and every Package.swift file. It seems like SPM is only finding includes by itself if they are in the exact same directory as the Package.swift file 🙄 That's not at all helpful… Has anyone found a way to do useful includes into Package.swift files? Any help appreciated. Thank You Roddi

Cannot debug app-extension-safe frameworks in main app
The code in my app is split into frameworks that I can use both from my main app and its app extensions. In order to use the frameworks inside the app extension, I need to build them with the Xcode build setting Require Only App-Extension-Safe API set to Yes. When I do that, debugging framework code in my main app no longer works properly. I can set a breakpoint, but any attempt to print a value via p or po will give a set of errors like the following: error: module file /Users/.../Library/Developer/Xcode/DerivedData/...-daqfgouagvlkudfebrmzrurogmld/Build/Intermediates.noindex/SwiftExplicitPrecompiledModules/_errno-B8I5WSZMM09RXHYLYEWSC1BLE.pcm cannot be loaded due to a configuration mismatch with the current compilation error: Objective-C App Extension was enabled in PCH file but is currently disabled How do I fix this?

iOS Crash Log Shows High Offsets & ??? Modules in Local Debug Build (Binary Images Missing Main Binary)
Hi all, I'm encountering a strange crash issue during local iOS debugging on a real device, and I'm hoping someone can help explain it. The crash log contains unusually high offsets that are completely outside of any module address ranges listed in Binary Images. For example: 6 ??? 0x129ac0ee8 -[...:] + 1052 But the Binary Images section shows: 0x102358000 - 0x102363fff ChinaMobile arm64 ... 0x11bb2c000 - 0x11bdeffff ChinaMobile.debug.dylib arm64 ... ... There are two binaries for my app listed here, but neither matches that high crash address (0x129ac0ee8). Additionally, sometimes the Binary Images section doesn't even include my app's binary at all, which makes the crash logs even harder to analyze. This crash definitely happens inside my main app’s business code, yet the crash offset doesn’t match any listed binary range. Also, the crash logs contain many ??? module names and missing symbols, even though I'm running a Debug build locally, and I know how to symbolize logs manually. My Questions: Why does the crash log show such high offsets, far beyond any Binary Images' range? Why does it have so many ??? entries and missing symbols, even in a local debug build? Could this be related to Xcode version, build settings, or some project misconfiguration? Any suggestions or insights would be greatly appreciated!

SpringBoard Crashes on macOS Simulator When Receiving Critical Alerts
I’m experiencing a consistent crash of SpringBoard on macOS when running my iOS app in the Simulator. The crash occurs specifically when a critical alert (geofence notification) is triggered by my server and delivered to the app. Xcode version: 16.4 macOS version: 15.5 App uses UNUserNotificationCenter with critical alert notifications related to geofencing. When the critical alert is received, SpringBoard quits unexpectedly on macOS, crashing the Simulator UI to the home screen. The notification is delivered by Firebase, and I have updated to the latest version of that. The console shows: XPC connection interrupted [C:1] Error received: Connection interrupted. [C:1-2] Error received: Connection interrupted. This does not happen when testing on a real device — the app works fine there, however, Springbaord still crashes on macOS. Please advise if this is a known issue or if there’s a workaround. This severely impacts development and testing of location-based critical notifications. The last time I tested this functionality, with an older version of Xcode, I had no issues. Thank you for your help.

Is it possible to embed dependencies within a .xcframework?
I'm creating a .xcframework in order to deliver an api/functionality to a customer for inclusion into an app. I'm doing it as a .xcframework as I want it to be a binary so that the source code isn't accessable. The xcframework has dependencies on modules which are installed via SPM (there are a few, an example is PhoneNumberKit) When I build the xcframework and then add it to a test program and invoke its api then there's a run time error saying "PhoneNumberKit/resource_bundle_accessor.swift:44: Fatal error: unable to find bundle named PhoneNumberKit_PhoneNumberKit" How can I build the xcframework so that its dependencies are included within it? (Stepping back a bit, is an xcframework an appropriate approach for this?)

Refactor->Rename "Refactoring Engine Failure"
For Xcode 15 and Xcode 16, whenever I try to use the Refactor->Rename command I get a spinning busy cursor for a short while then I get an alert that says: Rename Failed Refactoring engine failure. This happens on several projects and I've tried removing the derived data folder, but am at a loss to find additional troubleshooting steps. Are there other files I might remove or reset to get my "Refactoring Engine" back into shape?

Microphone is not being detected in Safari on iOS
What I am trying to do is very simple. Environment description: macOS Catalina version 10.15.7 iOS Simulator version 12.3 Target device iPhone 11 (iOS 13.2.2) Open Safari > go to website > mictests.com Result: "Could not find any media devices. It is very likely that your browser does not allow access to these devices." The Simulator does have access to the microphone. I can use Siri just fine. Only Safari cannot access the mic. I'm really stuck here, any ideas are welcome.

Bug in Xcode AI coding assistant
I've been experimenting with using local LLMs in place of ChatGPT in coding assistant. I was able to do this using LM Studio. I found that switching LLMs was a little clunky, but eventually, I was able to make it work. However, none of the LLMs I tried were able to generate error free Swift code. Not surprising at this stage. I decided to train an LLM (Llama3.1-8b) with Apple's Swift Programming language reference, using Open WebUI, and this worked. I was able to get the LLM to generate working Swift Code that I was able to test in Playgrounds. The problem I'm having now is that Xcode is locked up on the last LLM I tried out. I've tried deleting all the LLM providers in Settings, leaving only ChatGPT, but Xcode still defaults to the local LLM, even though it throws errors if you try to ask it a question. I've tried reinstalling Xcode, downloading new versions of sample Xcode projects, and deleting various data files, all to no avail. I would really like to test the new LLM I've trained in coding assistant, but right now, Xcode won't let me. It won't even let me revert to ChatGPT.

Tabbar UITest bug on tvOS
When running UITests on tvOS, tabBar viewIdentifiers (UIKit) are no longer appearing. When you run the test, accessibility identifiers for tabs are no longer locatable but all other identifiers appears except for the tabs in the tabBar. In the stack trace of the debugger, if I print application, I can see all existing viewIdentifiers except those that were set for the tabs (on tvOS only). If I force an action on the simulator after the app has launched and the view appeared ie move left or right, the identifiers appears (confirmed by stack trace) and the test will continue as expected. This was not an issue in the past (no code changes). I am not sure if this appeared after updating my mac to Sequoia. But for iOS, there is no issue. This bug only appears on tvOS and specifically the tabs. Issue persists on: Sequoia 15.4.1 Xcode 16.3

Playground with a Logger - Error: Couldn't look up symbols: __dso_handle
Xcode 16.4, MacOS Sequoia 15.5 If I try to use a logger in an Xcode Playground e.g. import os import UIKit var logger = Logger(subsystem: "Loggertest", category: "") logger.info("Hello, world!") I get the following error error: Couldn't look up symbols: ___dso_handle ___dso_handle Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler. Its the logger.info ... that is causing the error. I have raised FB18214090 but there are no other reports. I would be grateful if some of you could verify if the Playground runs or errors on your system. A workaround, still using Logger, would be a great help. Thanks, Chris

UIScene Storyboard - Main and Main_iphone
Under threat of future crashes, I'm adding support of UIScene to my existing apps. Each app has two storyboards - Main for iPads and Main_iphone for iPhones. Pre-UIScene, all looks great. With the addition of the Application Scene Manifest, the iPhone versions of the app are using the Main storyboard instead of the Main_iphone storyboard. Do I need to add an item to the plist for this other storyboard? At what level in the plist is this added? Another Scene Configuration? Another Window Application Session Role? Another Storyboard Name?

run XCUITest with an SKStoreReviewController
I'm building out a number of XCUITests. At one stage in my app, we present an SKStoreReviewController to ask the user if they'd like to review the app now. All I'd like to do is dismiss the view, by hitting the "Not Now" button. Normally, for other "system" views, I'd something like this: let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let notNowButton = springboard.buttons["Not Now"] And then I'd do an appropriate 'wait' and tap action. But for some reason, this isn't working. Looking for advice on how to properly handle this screen.

For Xcode 15 and Xcode 16, whenever I try to use the Refactor->Rename command I get a spinning busy cursor for a short while then I get an alert that says: Rename Failed Refactoring engine failure. This happens on several projects and I've tried removing the derived data folder, but am at a loss to find additional troubleshooting steps. Are there other files I might remove or reset to get my "Refactoring Engine" back into shape?

Run on Main Actor for Swift Packages
I'd like to know if there is a new property we can use in the definition of a Swift Package in the new Xcode 26, where we can set the whole package to run on Main Actor, as we have it in our apps for Xcode 26.

Microphone is not being detected in Safari on iOS
What I am trying to do is very simple. Environment description: macOS Catalina version 10.15.7 iOS Simulator version 12.3 Target device iPhone 11 (iOS 13.2.2) Open Safari > go to website > mictests.com Result: "Could not find any media devices. It is very likely that your browser does not allow access to these devices." The Simulator does have access to the microphone. I can use Siri just fine. Only Safari cannot access the mic. I'm really stuck here, any ideas are welcome.

Bug in Xcode AI coding assistant
I've been experimenting with using local LLMs in place of ChatGPT in coding assistant. I was able to do this using LM Studio. I found that switching LLMs was a little clunky, but eventually, I was able to make it work. However, none of the LLMs I tried were able to generate error free Swift code. Not surprising at this stage. I decided to train an LLM (Llama3.1-8b) with Apple's Swift Programming language reference, using Open WebUI, and this worked. I was able to get the LLM to generate working Swift Code that I was able to test in Playgrounds. The problem I'm having now is that Xcode is locked up on the last LLM I tried out. I've tried deleting all the LLM providers in Settings, leaving only ChatGPT, but Xcode still defaults to the local LLM, even though it throws errors if you try to ask it a question. I've tried reinstalling Xcode, downloading new versions of sample Xcode projects, and deleting various data files, all to no avail. I would really like to test the new LLM I've trained in coding assistant, but right now, Xcode won't let me. It won't even let me revert to ChatGPT.

Tabbar UITest bug on tvOS
When running UITests on tvOS, tabBar viewIdentifiers (UIKit) are no longer appearing. When you run the test, accessibility identifiers for tabs are no longer locatable but all other identifiers appears except for the tabs in the tabBar. In the stack trace of the debugger, if I print application, I can see all existing viewIdentifiers except those that were set for the tabs (on tvOS only). If I force an action on the simulator after the app has launched and the view appeared ie move left or right, the identifiers appears (confirmed by stack trace) and the test will continue as expected. This was not an issue in the past (no code changes). I am not sure if this appeared after updating my mac to Sequoia. But for iOS, there is no issue. This bug only appears on tvOS and specifically the tabs. Issue persists on: Sequoia 15.4.1 Xcode 16.3

Playground with a Logger - Error: Couldn't look up symbols: __dso_handle
Xcode 16.4, MacOS Sequoia 15.5 If I try to use a logger in an Xcode Playground e.g. import os import UIKit var logger = Logger(subsystem: "Loggertest", category: "") logger.info("Hello, world!") I get the following error error: Couldn't look up symbols: ___dso_handle ___dso_handle Hint: The expression tried to call a function that is not present in the target, perhaps because it was optimized out by the compiler. Its the logger.info ... that is causing the error. I have raised FB18214090 but there are no other reports. I would be grateful if some of you could verify if the Playground runs or errors on your system. A workaround, still using Logger, would be a great help. Thanks, Chris

UIScene Storyboard - Main and Main_iphone
Under threat of future crashes, I'm adding support of UIScene to my existing apps. Each app has two storyboards - Main for iPads and Main_iphone for iPhones. Pre-UIScene, all looks great. With the addition of the Application Scene Manifest, the iPhone versions of the app are using the Main storyboard instead of the Main_iphone storyboard. Do I need to add an item to the plist for this other storyboard? At what level in the plist is this added? Another Scene Configuration? Another Window Application Session Role? Another Storyboard Name?

run XCUITest with an SKStoreReviewController
I'm building out a number of XCUITests. At one stage in my app, we present an SKStoreReviewController to ask the user if they'd like to review the app now. All I'd like to do is dismiss the view, by hitting the "Not Now" button. Normally, for other "system" views, I'd something like this: let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let notNowButton = springboard.buttons["Not Now"] And then I'd do an appropriate 'wait' and tap action. But for some reason, this isn't working. Looking for advice on how to properly handle this screen.
