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?

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.

​Environment​： Xcode Version: 16.0 (latest stable release) iOS Version: 18.3.1 Devices: physical devices Configuration: Main Thread Checker enabled (Edit Scheme > Run > 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’m currently using the stable release of Xcode 16.4, and I’m considering installing macOS beta 26. Before I upgrade, I’d like to know: 👉 Is it generally possible to use Xcode 16.4 with macOS Tahoe beta? My goal is to continue building and submitting apps to the App Store using the non-beta Xcode version. I understand that Apple only officially supports each stable Xcode with the current public macOS release, but in practice, has anyone run into issues doing this? This would not be my primary development Mac, but I’d still like to be able to compile and test code on the machine running the macOS beta. I’d appreciate any experiences or official guidance — especially regarding app signing, archiving, or compatibility with Xcode Cloud. Thanks in advance!

I have an Xcproject that I am using to define a .framework target that includes Objective-C++ bridges for a whole slew of C++ libraries. To bridge Objective-C++ to Swift code in a separate target, I am using a .modulemap file that I generate in a script. So we've essentially got App.xcproject App target { Dependency on Bridges.framework } Bridges.xcproject Bridges.framework { Dependency on generate-modulemap + a whole slough of c++ libraries } generate-modulemap It is VERY expensive for the Bridges framework to need to compile each build. The generation of the bridge static library takes 21 seconds, and the signing of it takes 32 seconds. I would like to get generate-module to have its RunScript phase run based on dependency analysis. This way a new modulemap is only made when there is a new header and I can avoid compiling the whole framework each build. Normally, I would just list all of the headers in the input list to the script, but in this case, the goal is more to have it be any file within that folder. However, it is very unclear how to do so. Is there a way to get the "based on dependency analysis" to go based on any file within a folder? A filelist does not work here because the filelist does not get updated automatically when you add a new header into that folder.

I have enabled Code Review with the button and then String Catalog turned up to code view anyways i can't get it back to original view. Disable Code Review button doesn't do anything. Any idea?

I have a project which is set up like so App.xcproject App target { Dependency on Bridges.framework } Bridges.xcproject Bridges.framework Bridges.framework has a bunch of Objective-c++ headers that import c++ headers/frameworks etc. It has a modulemap that allows it to generate bridging headers for the App target which is Swift only. I have noticed that every single build Planning Swift module App is run for 1 second, then Precompile bridging header is run for a moment, then every single swift file that imports Bridges recompiles regardless of if it had any edits taking about 2-3 seconds. It feels like since nothing has changed inside of Bridges that this bridging header precompile should not be necessary every single run. Bridges.framework is in General/Frameworks as "Do not embed" Bridges is in build phases "Target dependencies" and "Link binary with libraries" Is this just normal and I should let this slide or is there a way to avoid this?

I just noticed this today while building a React Native app. Anybody else seen this and know what it means/how to track it down/how to fix it

I'm primarily an iOS developer. Every day that I develop, Mac Time Machine backs up a gigabyte or more of data. I'm trying to reduce that as much as possible. No data involving the simulators seems important enough to backup. If I ever need to restore Xcode, I'd reinstall rather than restore from Time Machine. But I'd want to back up code snippets, etc. What are the best practices to prevent large amounts of Xcode or simulator data from being backed up?
