Hello, we are struggling for hours with the following issue: I have an individual developer account and since yesterday I'm member of developer team with an own organization account. I have access to an app in the team account as an "App-Manager", also the option "Access to Certificates, Identifiers & Profiles" is activated and I can see that it is activated for my account in AppstoreConnect. In "Apple Developer" I can also see the team and can switch to. But then I do not see the "Certificates, Identifiers & Profiles" menu entry. Also the team is not showing up in XCode. What am I missing? Thanks and regards Philipp

I'm testing a c++ project. I would like multiple XCTest files to be able to use this function: void testGLMVEC3(const glm::vec3& actual, const glm::vec3& expected) { XCTAssertEqualWithAccuracy(actual.x, expected.x, 0.00001f); XCTAssertEqualWithAccuracy(actual.y, expected.y, 0.00001f); XCTAssertEqualWithAccuracy(actual.z, expected.z, 0.00001f); } I'm not sure how to do this. I don't think I should put this function in my project code. I'd like it to be in my XCTest files. (I wouldn't know how to put it in my project code anyhow.) Here's how I'd expect to use it: #import <XCTest/XCTest.h> #import "../OrangeSpider/SpLeftLeg.hpp" ... @interface SpLeftLegTest : XCTestCase @end @implementation SpLeftLegTest - (void)setUp {} - (void)tearDown {} - (void)testGetPoints{ // Set up float topLength = 10.0f; ... // Actual SpLeftLeg SpLeftLeg spiderLeg{spLegAnatomy, spLegAngles, minExtensionAngles, maxExtensionAngles}; // Test points testGLMVEC3(spiderLeg.getConnectionPoint(), glm::vec3(0.0f, 0.0f, 0.0f)); } - (void)testPerformanceExample { [self measureBlock:^{ }]; } @end

I just submitted a feedback for this (FB9662125) but in the spirit of “share and enjoy”… The cool new Generate Info.plist File feature in Xcode 13 crashes if you try to put an NSLocationTemporaryUsageDescriptionDictionary in your Info.plist file. Here’s a simple repro scenario: Create a minimal iOS app (no Core Data, no tests) Go to target settings → Info tab → Custom iOS Target Properties Click the (+) button on any row to begin inserting a new row Select Privacy - Location Temporary Usage Description Dictionary Click somewhere else or press Return to commit the selection Xcode crashes immediately More generally, it seems that Xcode crashes any time it tries to regenerate your Info.plist file if it contains an NSLocationTemporaryUsageDescriptionDictionary, even if (for example) you manually pasted that dictionary into the file earlier. In that case, merely tapping the (+) button in step 3 above is enough to crash it.

I'm attempting to compile my app (on macOS 26), opting into the "Enhanced Security" (Xcode Version 26.0.1 (17A400)). Following Apple's documentation I enabled the capability via Xcode and clicked "Enable Build Settings" though now compilation fails: Use of undeclared identifier 'malloc_type_zone_malloc_with_options_backdeploy'; did you mean 'malloc_type_zone_malloc_with_options'? The (AI-based?) "Generate Fix for Issue" throws an error too 😅 See attached screenshots

I'm trying to sign-in with a Sandbox account with my iOS simulator. Using Xcode 26 beta 7. After I sign in, the button goes inactive for a few seconds but then nothing happens. It does not actually sign me in.

After updating my Xcode to the latest, I am unable to download an installed app container from the Xcode Devices screen. This currently works with older versions of Xcode with the same app on the same iPad. This worked with older versions of Xcode on the same MacBook as well (including the Xcode 26 beta before updating to the official release yesterday) The specified file could not be transferred.

When attempting to download the iOS 26 simulator runtime from Xcode → Settings → Platforms, the process fails with the following error: (-67061 invalid signature (code or signature have been modified) Domain: SimDiskImageErrorDomain Code: 5 User Info: { unusableErrorDetail = ""; } Even after manually importing other runtimes (e.g., iOS 18.2), they do not appear under Xcode → Product → Destination, and the simulator list remains empty. System Information: macOS: 26.0.1 (Build 25A362) Xcode: 26.0.1 (24229) (Build 17A400) Processor: Intel Core i5 (Intel-based Mac) The error occurs consistently each time I try to download the runtime, preventing Xcode from adding the iOS 26 simulator. No third-party tools or manual modifications were made to Xcode. What I’ve Tried: Restarted Xcode and macOS Cleared DerivedData and simulator cache Verified Xcode path via xcode-select -p Imported iOS 18.2 runtime manually using: xcodebuild -importPlatform "iOS_18.2_Simulator_Runtime.dm Reset CoreSimulator service and re-created simulators via xcrun simctl Despite all of this, no simulator appears in Xcode’s destination list, and I keep getting the signature validation error when trying to download iOS 26 from Xcode.

Xcode 26 run an very old iOS project, when run in iPhone 17 series simulator, it get XXX's architectures (Intel 64-bit) include none that iPhone 17 can execute (arm64), and when I run in iPhone device, it works correctly. The project setting is in the picture below.

I didn't check this out specifically on earlier betas, but AI is allowed to create new .swift files, yes? I'm only seeing proposals to create files (as opposed to code which it can change automatically), and the CREATE FILE button to the right of any proposed file creation does nothing. Next I'll mention running local models, but file creation does not seem to happen for neither ChatGPT nor any local model. Also I'm experimenting with LM Studio and it is reporting my client is timing out. So I guess Xcode is not waiting long enough for a response? The local models are slow, yes. But is there a setting for the AI timeout value? I told the LLM "Every 1 minute send me an update so I know you are still working so my client does not time out" which seems to have no visible effect, it hasn't timed out yet, but I don't visibly see that message.

I'm trying to find the installer for Metal Toolchain 26. It seems to fix an issue I have but I don't want to have to install Xcode 26 just to get the toolchain installed. Is this possible?

I have been trying to update an app of which the code base hasn't changed in two years. It still builds fine and runs fine, on simulator and device, but... when uploading it to Testflight I get the error "The app contains one or more corrupted binaries. Rebuild the app and resubmit.". I have been rebuilding like a maniac, trying to look at what could be wrong with the binary, I let ChatGPT misguide me on the log files, I think I have tried everything... but to no avail. Any ideas how I could find out what goes wrong?

I have been trying to run the ios build and facing issues since last few days. I installed xcode with ios26 and switched to xcode 16.2 beta and now in xcode16.1. My development is blocked as am hitting errors one after the other. Can you point me to any configuration which works ? My development is blocked and its real pain.

Whenever I hit play on my app to test it on the Mac the register .app part starts taking more than 15 minutes, this is severely impacting my work. There's no indication on what's wrong and how can I fix this.

I use spm manage swift package, now i want my macos app support arm64e,so i add arm64e in Build Srtting -> Architectures. but i got error Could not find module 'SwiftyJSON' for target 'arm64e-apple-macos'; found: arm64-apple-macos, x86_64-apple-macos Apparently, if no limit in Package.swift, SPM will only compile versions for x86 and ARM64 architectures by default. now, how should I configure SPM to compile the arm64e version? thanks

Mostly a heads up, maybe this will help other people. I had a very simple test app for MacOS, just a ViewController with an OutlineView that had two columns, and the column data was initialized in awakeFromNib of the NSViewController like this: override func awakeFromNib() { if dataArray.count == 0 { dataArray.append( Node( firstname: "John", lastname: "Doe" ) ) dataArray.append( Node( firstname: "Mary", lastname: "Smith" ) ) } self.content = dataArray } There's also a toolbar with a button and a search field. This worked perfectly fine on Sequoia and Xcode 16, but since I updated to Tahoe and Xcode 26, if I try to run/debug the app from Xcode it hangs and eventually crashes. If Debug Executable is enabled in the scheme the crash is in libMainThreadChecker with EXC_BAD_ACCESS, and without debug it's a crash report with "Thread stack size exceeded due to excessive recursion". I found that if I moved the self.content assignment inside the if block the problems went away: override func awakeFromNib() { if dataArray.count == 0 { dataArray.append( Node( firstname: "John", lastname: "Doe" ) ) dataArray.append( Node( firstname: "Mary", lastname: "Smith" ) ) self.content = dataArray } } There's a good chance I was abusing awakeFromNib() and shouldn't have been doing the assignment in there, etc. It was just a local test app, no big deal for me. But maybe something changed between Sequoia and Tahoe with respect to that function and how/when it's triggered?

When comparing the Assets.car file of the previous and current versions of my app, compiled with Xcode 16 and 26, respectively, with the Terminal command assetutil --info MyApp.app/Contents/Resources/Assets.car I see that the new version contains many more app icons at different sizes, increasing my app's size by 1 MB (not much, but considering that the app is only 6 MB in total...): { "AssetType" : "MultiSized Image", "Name" : "AppIcon", "NameIdentifier" : 6849, "Scale" : 1, "SHA1Digest" : "9D75F76992E9E9E5531A214A4AE282EBD381F7EB903024E00FB25EB42381CC45", "SizeOnDisk" : 308, "Sizes" : [ "16x16 index:1 idiom:universal", "32x32 index:2 idiom:universal", "64x64 index:3 idiom:universal", "128x128 index:4 idiom:universal", "256x256 index:5 idiom:universal", "512x512 index:6 idiom:universal", "1024x1024 index:7 idiom:universal" ] } The previous one allowed me to add only two sizes: { "AssetType" : "MultiSized Image", "Name" : "AppIcon", "NameIdentifier" : 6849, "Scale" : 1, "SHA1Digest" : "AC782A2FFF9A4B2D563EF64DF41A179583440560F8732A176A8376B31000368E", "SizeOnDisk" : 248, "Sizes" : [ "256x256 index:1 idiom:universal", "512x512 index:2 idiom:universal" ] } Is there a way to only ship the strictly necessary app icons sizes while using Xcode 26 Icon Composer, or will all the sizes be required going forward?

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.

After updating to Xcode 26 RC on Tahoe 26 RC and iOS 26 RC (and now final version of both Tahoe and iOS). I'm still unable to debug on device. I've tried rebooting, resetting settings, cleaning trusted computers. I ran out of ideas, I was expecting that final versions would fix this but they didn't.
