I would like to delete this post, but I can't. Please add this fundamental feature.

Hi! I was wondering when the maintenance of the Apple Developer website will end as I need to register a new App ID for my project. I know that WWDC just ended, but is there an estimate for this?

ISSUE: Warning: None of the input catalogs contained a matching App Icon & Top Shelf Image brand assets collection named "AppIcon" INFORMATION: So I currently have my app published and it works for iOS, and visionOS. (iPhone, iPad, Mac & Apple Vision Pro) There is one target for all OS versions. I have recently updated it to work with tvOS, however upon building I run into the warning listed at the top of this post. I have the following within the project: 'AppIcon.icon' (from the new icon composer for iOS, macOS and watchOS) And within .xcassets: 'AppIcon' (which contains the majority of the icons) 'Brand Assets' Folder (created by right click, tvOS, New tvOS App Icon and Top Shelf Image; which contains these icons in layers and the correct sizes) Brand Assets retains the names created by Xcode, App Icon - App Store, App Icon, Top Shelf Image Wide, Top Shelf Image In "General" in the target, I have AppIcon, still listed as the AppIcon name. Adding a second entry here for just tvOS does not resolve my issue, our could be that I do not what to call it so it can properly find it. QUESTION: What am I missing so that the build process detects these images properly and completes a successful build for tvOS? I am assuming I need to add options to the App Icons and Launch Screens area, but what is the name I place here for tvOS? SCREENSHOTS:

How do I take an Icon Composer file and bring it into Xcode? The WWDC 25 session video "Create Icons with Icon Composer", Delivery chapter (around 13:16) was not detailed enough on how to bring the file into Xcode so it will be used for the project. Once I've saved the Icon Composer file to Finder, where do I import/put it into my Xcode project. I have previous App Icon content in Assets. Do I add Icon Composer file content to Assets in Xcode? How do I make sure Xcode uses the new Icon Composer content in my Xcode project (for iOS) vs. the App Icon asset I currently use?

Hello, I normally don't update to the latest macOS version until it is stable. However, I really want to try the Xcode intelligence features. Do you guys just update your Mac to the latest beta version? Or do you partition your drive? Is there a better way than partitioning now? It's been a long time since I partitioned. Thanks

Has anyone been able to use Google Gemini with Intelligence in Xcode? I got the Claude models working in there but as much as I try I can't see any Gemini models.

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.

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?

Hey everyone, I’m trying to enroll in the Apple Developer Program as a company (LLC), and I’m the sole owner and CEO. I uploaded all the documents required, but when I try to re-upload the missing one using their upload link, I get this error message: “Sorry, you don’t have access. Your account isn’t authorized to upload files.” Has anyone faced this before? Is there a fix or do I need to contact Apple directly? Also, they’re asking for a business card or an employment verification letter — but I’m the owner and don’t have either. How do you handle this if you’re the only person in the LLC? Do I just create a business card or write the verification letter myself? Any help or advice would be much appreciated. 🙏 Thanks in advance!

My ultimate aim is to be able to prevent Xcode from single-stepping into certain C++ functions - just as it does not single-step into std:: functions. It appears to be possible to arrange this by making a more elaborate version of an LLDB setting such as this: target.process.thread.step-avoid-regexp (regex) = ^std:: It also appears to be possible to put this setting into an "lldbinit" file so that LLDB (within Xcode) picks up the setting automatically when a debugging session starts. What I do not know is this: Where do I put the "lldbinit" file inside my project? What Xcode project or target settings need to be made to tell Xcode where to find my "lldbinit" file and use it?

I've updated my computer to Sequoia 15, Xcode 16 and now no matter what I do, I am unable to work with Swift UI previews. I get this error each time I try to run the preview: Failed to launch app in reasonable time I have done: Uninstall/Re-install Xcode Deleted derived data Deleted the simulator data Used DevCleaner to remove all data related to Xcode Searched all websites about this issue. ( Non shown a good solution ) Write this question on here. If anyone has found a solution, please let me know how you fixed it.

I'm finding developing for HomeKit using the iOS Simulator utterly confounding. All of my home's actual HomeKit accessories show up fine when I run the HomeKit app I'm developing on my actual phone. But none show up when I run my app in the iOS Simulator. Maybe that's how it's supposed to be? I decided to run the HomeKit Accessory Simulator in an attempt to get something to show up in the iOS Simulator, but the accessories I've created there don't show up in the Simulator either. How do I get devices to show up in the iOS Simulator? Thanks.

​Environment​： Xcode Version: 16.0 (latest stable release) iOS Version: 18.3.1 Devices: physical devices Configuration: Main Thread Checker enabled (Edit Scheme &amp;gt; Run &amp;gt; Diagnostics) ​Issue Description​ When the ​Main Thread Checker​ is enabled, methods defined in a UIViewController category (e.g., supportedInterfaceOrientations) fail to execute, whereas the subclass implementation of the same method works as expected. This conflicts with the normal behavior where ​both implementations should be called. ​Steps to Reproduce​ 1、Declare a category method in UIViewController+Extend.m: // UIViewController+Extend.m @implementation UIViewController (Extend) - (UIInterfaceOrientationMask)supportedInterfaceOrientations { NSLog(@"category supportedInterfaceOrientations hit"); return UIInterfaceOrientationMaskAll; } @end 2、Override the same method in a subclass ，call super methed(ViewController.m): // ViewController.m @implementation ViewController - (UIInterfaceOrientationMask)supportedInterfaceOrientations { NSLog(@"subclass called supportedInterfaceOrientations called"); return [super supportedInterfaceOrientations]; // Expected to call the category implementation } @end 3、​Expected Behavior​ (Main Thread Checker ​disabled): subclass called supportedInterfaceOrientations called category supportedInterfaceOrientations hit 4、Actual Behavior​ (Main Thread Checker ​enabled): subclass called supportedInterfaceOrientations called // category supportedInterfaceOrientations hit ​Requested Resolution​ Please investigate: 1、Why Main Thread Checker disrupts category method invocation. 2、Whether this is a broader issue affecting other UIKit categories.

This is the issues I faced: NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed How can I fix it because I'm not sure if I dowloaded the application correctly.

Hi, The ui error says unable to login, but I'm able to login (because if I don't give the correct password it's a different error). When Xcode tries to fetch the available teams though it errors out. I can successfully login and access my teams on a different machine that's on the same network. So I know the account and network are fine. Here's what the ui shows .. and I'm also including the Xcode logs from Console. Any ideas? Thanks! xcode.log

While test driving Xcode on macOS 26, Intelligence is showing unavailable in region error. I am in the US, and I would love to try it out.

Still getting the error message "Failed -- Failed to find asset: com.apple.gm.safety_deny.input.code_intelligence.base.generic - no asset" Tried all the recommended solutions, toggling Apple Intelligence and Siri Toggling Value under "Editing" in settings: " check-box Predictive code completion" no help Still download fail with above message (plenty of disk space)

I have used lots of Xcode versions but I feel like this is the best version I have ever used in my life, so smooth and looks great, like the glassy and simple look and the new tab system Is great!!!

I would like to inquire about a concern related to the app review process. Specifically, I would like to understand if forcefully denying an application's execution on the iOS Simulator (for instance, by implementing a check in the code that prevents the app from running in a simulated environment) could negatively impact or delay the app’s approval during the App Store review process. This measure is intended solely for security and integrity reasons during development and distribution. The app functions normally on real devices, and all other guidelines and requirements outlined by Apple are being strictly followed. Could you please confirm whether such a restriction on the Simulator is acceptable, and if there are any best practices or recommendations from Apple regarding this? Thank you for your support, and I look forward to your guidance.
