Xcode 26.0 beta: Double-click in Navigator Doesn’t Open File in New Tab
Issue Report — Xcode 26.0 beta (17A5241e) In Xcode 26.0 beta, double-clicking a file in the project navigator does not open it in a new tab as it normally should. Instead, it opens the file in the current editor window. Interestingly, Option-clicking a file still opens it in a new tab as expected. I’ve confirmed that my Navigation preferences are properly set (see the attached screenshot), so this seems like a possible regression or bug in the current beta version.

Swift Playgrounds macOS repeatedly asks “My App would like to access data from other apps”
Environment: Swift Playgrounds (macOS) SwiftUI App Preview macOS version: 26.2 (25C56) Issue: In Swift Playgrounds on macOS, the app repeatedly shows the system permission dialog: “My App would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.” Steps to Reproduce: Create a new SwiftUI app in Swift Playgrounds. Run the SwiftUI App Preview. When the permission dialog appears, click “Allow”. Expected Result: The permission should be granted once and persist, allowing the preview to continue normally. Actual Result: After clicking “Allow”, the SwiftUI App Preview crashes and restarts. When the preview restarts, the same permission dialog appears again. This repeats indefinitely, creating a loop. Notes: This occurs even when no explicit file system or inter-app data access code is written. The permission choice does not appear to persist between preview restarts. Question: Is this a known limitation of Swift Playgrounds sandboxing or SwiftUI App Preview? Is there an official workaround or recommended approach to avoid this behavior while using Swift Playgrounds?

Attributes inspector in Xcode 26
It has been two years since I wrote my a SwiftUI app, and I wanted to start again in Xcode 26. I can no longer see the attributes inspector when I select an element in the canvas. This was an Xcode feature that was very helpful as I am still a novice. Has this feature been deprecated in Xcode 26? And if not, please help explain how I can find and use it.

Xcode 26 Beta 4 Build Failures
We are trying to track down some build failures that started happening only in our Jenkins CI environment. error: Failed to decode version info for '/Applications/Xcode.app/Contents/Developer/usr/bin/actool': The data couldn’t be read because it is missing.

If I run this locally or if I remote into the CI machine and run this from the terminal I cannot reproduce this behavior.

We've tried to recreate the build agents for this jenkins environment exactly as they were for all previous betas and xcode versions, and still get this behavior.

iOS15 on Xcode26 / Symbol not found: _SKStoreProductParameterAdNetworkSourceIdentifier
Below is an English version of your post, ready to copy-and-paste into the Apple Developer Forums: I’m seeing a crash in Xcode 26 beta 3 whenever the StoreKit symbol SKStoreProductParameterAdNetworkSourceIdentifier is present while running on an iOS 15 simulator. Steps to reproduce Install Xcode 26 beta 3. Create any iOS app and run it on an iOS 15 simulator (device model doesn’t matter). Add the following code anywhere and run: override func viewDidLoad() { super.viewDidLoad() if #available(iOS 16.1, *) { print("SKStoreProductParameterAdNetworkSourceIdentifier: \(SKStoreProductParameterAdNetworkSourceIdentifier)") } } The project builds successfully, but before the #available(iOS 16.1, *) check is reached, the app crashes with: Symbol not found: _SKStoreProductParameterAdNetworkSourceIdentifier When I build the same project with Xcode 16.4 and launch it on an iOS 15 simulator, it runs without crashing. Investigation so far Because SKStoreProductParameterAdNetworkSourceIdentifier is just an NSString, I could substitute the string literal "SKStoreProductParameterAdNetworkSourceIdentifier" as a temporary workaround, but that doesn’t feel like a proper fix. The symbol is still declared in both SDKs: /Applications/Xcode-16.4.0.app/.../StoreKit.framework/Headers/SKAdNetwork.h:48: SK_EXTERN NSString * const SKStoreProductParameterAdNetworkSourceIdentifier API_AVAILABLE(ios(16.1)) API_UNAVAILABLE(macos, watchos, visionos); /Applications/Xcode-26.0.0-Beta.3.app/.../StoreKit.framework/Headers/SKAdNetwork.h:48: SK_EXTERN NSString * const SKStoreProductParameterAdNetworkSourceIdentifier API_AVAILABLE(ios(16.1)) API_UNAVAILABLE(macos, watchos, visionos); So the symbol hasn’t been removed in the beta SDK. Given that the code is wrapped in #available(iOS 16.1, *), I don’t believe the sample itself is at fault. Questions Could this be a bug in Xcode 26’s availability checking or linker? Has anyone else encountered the same issue or found a more robust workaround? Any insights would be greatly appreciated.

"Missing required icon file" when submitting to TF from Xcode 26 beta 1
Trying to submit a build to TF from Xcode 26 via Xcode Cloud (both for iOS and macOS). The operation fails with this message: Missing app icon. Include a large app icon as a 1024 by 1024 pixel PNG for the 'Any Appearance' image well in the asset catalog of apps built for iOS or iPadOS. Without this icon, apps can't be submitted for review. For details, visit: https://developer.apple.com/documentation/xcode/configuring-your-app-icon. If you’ve added an icon made with Icon Composer, visit https://developer.apple.com/app-store-connect/release-notes/ for details about known issues. I thought it's because Icon Composer icons may not be supported yet, but then that last sentence is confusing me. Does this mean that TF just won't support Xcode 26 uploads yet, or does it accept them and I need to provide legacy icons for my build?

How are Assets removed?
Hello, I'm trying to figure out the behavior of AssetPackManager.shared.remove(assetPackWithID: ). I'm working with MapKit tiles and currently working on trying projecting them correctly which involves serving the AssetPack locally, downloading, checking alignment, and then deleting and changing. My question is that remove(assetPackWithID: ) completes successfully and the asset pack is removed. This is confirmed by trying to remove the AssetPack again which throws an error. However, the asset is still appearing on MapKit after the removal. This is a bit odd as this persists not only with force killing, but also restarting the device. Please advise on how to properly remove an AssetPack. Thank you iPhone 15 Pro Max (iOS 26.0.1) iPhone 17 Pro Max (iOS 26.0.1)

How to Download IOS 26 beta runtime simulator using "xcodebuild" tool?
How to download the runtime simulators for the most recent Xcode 26 beta? The current download command I’m using doesn’t seem to work, and I’m encountering the following issues: The runtime simulator download command (xcodebuild) requires the version number to be specified explicitly. I’ve tried multiple variations of version names/numbers but haven’t been able to identify the correct naming convention used by Apple for the Xcode 26 beta simulator runtimes. $ xcodebuild -downloadPlatform IOS -exportPath ~/Downloads -buildVersion 26 Finding content...iOS 26 is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0 Finding content...iOS 26.0 is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0 beta Finding content...iOS 26.0 is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion "26.0 beta" Finding content...iOS 26.0 beta is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion "26.0_beta" Finding content...iOS 26.0_beta is not available for download. $ xcodebuild -downloadPlatform iOS -exportPath ~/Downloads -buildVersion 26.0_beta Finding content...iOS 26.0_beta is not available for download.

Swift Assist
Hi, I'm testing out Xcode 16 beta and I have a couple of questions: Is Swift Assist only available on Sequoia? I see that predictive code completion is per https://www.apple.com/newsroom/2024/06/apple-empowers-developers-and-fuels-innovation-with-new-tools-and-resources/, but I tried the beta on Sonoma and I'm not seeing it Regarding Swift Assist - I understand that code is only used to process requests and never stored on servers, and Apple will not use it to train machine learning models. However, my company's security team may still decide that using Swift Assist is too much of a risk. How can we disable it across multiple developer machines? Thank you!

Unable to launch tests in Xcode 26
I am trying to upgrade my app to use Xcode 26 and I cannot get my tests to launch. I am trying to launch tests to the simulator, and I always get this error after 300 second timeout: "encountered an error (The test runner hung before establishing connection.)" There are no other errors getting logged. I can run to the same simulator just fine, and in Xcode 16 the tests launch with no issues. The tests also run fine on an actual iPhone. Thanks in advance.
