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!

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.

Xcode 26: `IDERunDestination: Supported platforms for the buildables in the current scheme is empty` repeatedly logged when running tests from `.xctestrun` file
We are seeing repeated occurrences of the following log line in test runs triggered via .xctestrun files on iOS 26: IDERunDestination: Supported platforms for the buildables in the current scheme is empty. This line is printed n number of times after a test fails, significantly increasing test execution duration (2–3 minutes extra in some cases). The issue does not occur when tests are built and run together from Xcode directly — it’s specific to .xctestrun-based executions using xcodebuild test-without-building. Steps to Reproduce: Use Xcode 26 to build a sample XCTest target (we used a simple UI test project). Locate the generated .xctestrun file under DerivedData/.../Build/Products/.... Run tests using: xcodebuild -xctestrun /path/to/sample.xctestrun \ -destination "id=<device_id>" \ test-without-building Observe the logs during test failure. Observed Behavior: The log line IDERunDestination: Supported platforms for the buildables in the current scheme is empty appears multiple times. The test cleanup and teardown phase takes significantly longer (2–3 minutes). Expected Behavior: The log should appear once or not at all. Test cleanup time should remain consistent. Additional Information: Affects only iOS 26 devices and .xctestrun-based runs. Not reproducible on iOS < 26. Xcode 26 and 26.x beta versions tried. Reproducible both locally and on CI systems using real devices. Same .xctestrun file, when used on older OS versions, does not cause delay.

Unable to debug Memory Graph in Xcode: "an unknown error occurred launching the helper task"
I am not able to use the Debug Memory Graph tool as well as Leaks instrument inside Xcode to debug my project. I'm running my project on physical iOS device on running 18.3 version and I tested the project on two different MacBooks running Xcode 16.3 and 16.1. On both the same problem persists. I have also reinstalled the project on the device and tried restarting all devices and cleared DerivedData. Nothing helped.

PHAssetChangeRequest deleteAssets not working some time
Hello Team, I try to delete photo from Photos for that i used this method, [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ [PHAssetChangeRequest deleteAssets:@[assetToDelete]]; completionHandler:^(BOOL success, NSError *error) { }]; This method pops up a dialog with Don't Allow or Delete. But some time in some iPhones not respond PHAssetChangeRequest deleteAssets method that's why that completionHandler not called because of that i can't perform any operation of PHPhotoLibrary then after. If I restart my iPhone then it works. Many users of my app complained about this issue. I have an iPhone 11 with iOS 15.3. But some iOS 12,14,16 users also face the same issue. So what exact issue is there? Is it related to iOS or a method? Thanks, Ankur

No new Xcode beta Since 16.2 Release on Dec 11
Not a question, but a surprise. Did I miss something, but apparently there has been no new beta release (16.3) since Release of 16.2 on Dec 11. 2 months without betas is really unusual (in fact, it never happened and usually, next beta n+1 is even released before the final release of version n). So does that mean 16.3 will be a major update ? Wait and see.

SwiftData error: NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release
I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

Hi so i have a given project where I am trying to use components within the PhotosUI Framework with Xcode26 and Xcode26.0.1 Just for reference here is an attached screenshot This sample code compiled successfully with xcode16.4 and was in production. There is no change in the pbxproj file , all the build settings have remained the same. Attaching it for reference. project.pbxproj.txt While showing declarations of PHPickerViewControllerDelegate i get two options which is the same as in Xcode16.4 while browsing online found this reddit thread which is very similar https://www.reddit.com/r/Xcode/comments/1nkku20/my_project_wont_compile_after_xcode_26_update_due/ Pls help :)

macOS 26.0 Tahoe + Xcode 26.0.1 Simulator causes system-wide audio distortion
After upgrading to macOS 26.0 Tahoe and Xcode 26.0.1, I’ve noticed an issue with audio playback whenever the iOS Simulator is running. Device: MacBook Pro 13" (2020, Intel, 16GB RAM, 500GB SSD) Issue: Any sound played on the Mac (system sounds, music, videos) begins to break/distort once the Simulator is active. App Sounds: If the app running inside the Simulator plays audio, that audio also breaks/distorts. Previous Version: This issue did not occur on macOS Sequoia 15 or with Xcode 16. Everything was working fine before the upgrade.

Unable to launch + Attach to Mac Widget (Sonoma + Xcode 15)
Attempting to launch a widget in Debug mode on Sonoma from Xcode 15 is failing with the following message: attach failed (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.) Looking in console I see this message: macOSTaskPolicy: (com.apple.debugserver) may not get the task control port of (MacGalleryWidget) (pid: 1851): (MacGalleryWidget) is hardened, (MacGalleryWidget) doesn't have get-task-allow, (com.apple.debugserver) is a declared debugger(com.apple.debugserver) is not a declared read-only debugger What Xcode settings should I be looking at to rectify this? I suspect I may have something that's out of whack.

Xcode 16 Doesn't Display "Swift Compiler" Build Settings Sections
I am editing my iOS project in Xcode 16 and want to use the "Swift Compiler - Upcoming Features" section of the build settings to selectively enable the new Swift 6 language features. I have read the instructions for doing this and have dowloaded an Apple sample project and can see that section under the project and target-level Build Settings in the sample project However, when I open my Xcode project in XCode 16 that section does not appear. Is there any way for me to influence how Xcode 16 displays the build settings? In fact, no "Swift Compiler" sections appear at all under my project Build Settings (All | Combined). There is a "User-Defined" section that has the Swift Version, Compilation Mode and Optimization level. The project itself is several years old and was on a very old project version. I have upgraded my project document format to "Xcode 16" but it made no difference. I have compared my project and the sample project in a text editor and both seem to have similar structure. I tried removing unused and outdated settings from my project but that also had no effect. Is there an alternative to deleting my project file and adding the source files to it? I have a large project with multiple targets so that would be something I'd rather not do.

Cannot run apps that use the callAsyncJavaScript() method on older simulators
If I use the method callAsyncJavaScript() my app will compile, but it won't run on older simulators. Specifically, in a brand new Storyboard project, I added this to `viewDidLoad(): let webView = WKWebView() webView.callAsyncJavaScript("1", in: nil, in: .page) { result in print("\(result)") } This runs fine with Xcode 16.3 targeting the iOS 18.4 simulator. It doesn't work if I target the iOS 18.3.1 simulator or the iOS 17.5 simulator. It does work on an iPhone 15 Pro running iOS 18.4 and it works on an iPhone 12 Pro running iOS 17.7.1. It goes without saying that this used to work on Xcode 16.2 and earlier, since my real project has been using that API for 3 or 4 years now.

Xcode 16 and iOS 18 project not compiling
I updated Xcode and MacOS recently and haven't been able to compile my Flutter app on iOS devices/simulators since then. The error keeps changing every time I run it but here's one of the output in the terminal after running flutter run: Uncategorized (Xcode): Command SwiftGeneratePch emitted errors but did not return a nonzero exit code to indicate failure Error (Xcode): no such file or directory: '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/Session.modulevalidation' Error (Xcode): stat cache file '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/SDKStatCaches.noindex/iphonesimulator18.0-22A3362- db63dc9361471f152f572502bdbfe70a.sdkstatcache' not found Error (Xcode): unable to rename temporary '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/3F9VRK3CXAUUD/UIKit-1KHQ7M05IF VXC-56601391.pcm.tmp' to output file '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/3F9VRK3CXAUUD/UIKit-1KHQ7M05IF VXC.pcm': 'No such file or directory' Error (Xcode): could not build module 'UIKit' /Users/chiragbhansali/Chirag/Coding/Projects/app/test/build/ios/Debug-iphonesimulator/Flutter.framewo rk/Headers/FlutterAppDelegate.h:7:8 Error (Xcode): could not build module 'Flutter' /Users/chiragbhansali/Chirag/Coding/Projects/app/test/ios/Runner/GeneratedPluginRegistrant.h:9:8 Error (Xcode): failed to emit precompiled header '/Users/chiragbhansali/Library/Developer/Xcode/DerivedData/Runner-eifcguceazlwumgsyzegclqdrbqt/Build/Intermed iates.noindex/PrecompiledHeaders/Runner-Bridging-Header-swift_PB6A5GFLTNPC-clang_3F9VRK3CXAUUD.pch' for bridging header '/Users/chiragbhansali/Chirag/Coding/Projects/app/test/ios/Runner/Runner-Bridging-Header.h' Uncategorized (Xcode): Command PrecompileSwiftBridgingHeader emitted errors but did not return a nonzero exit code to indicate failure Uncategorized (Xcode): Command SwiftEmitModule failed with a nonzero exit code Uncategorized (Xcode): Command SwiftCompile failed with a nonzero exit code Could not build the application for the simulator. Error launching application on iPhone 16 Pro. What I have tried so far: Deleting iOS SDK and simulators Cleaning Xcode build cache using cmd+shift+k Creating a new Flutter project and trying to compile it (it failed so that reduces the chances of it being a Flutter issue) Clearing the DerivedData folder Clearing settings and cache of simulators Restarting laptop Versions: Xcode: 16.0 iOS: 18.0 MacOS: 15.1 (didn't work with 15.0 either) Flutter: 3.24
