Overview

I’m having a bit of trouble uploading my new icon to the App Store Connect. I created it entirely with Icon Composer, but it keeps throwing an error saying it’s an “Invalid large app icon.” The error message says that the large app icon in the asset catalog can’t be transparent or have an alpha channel. I only have one AppIcon in the asset catalog, and I’ve checked the “single size” option, which is set to 1024x1024 for any, dark, or tinted size. In the past, when I used the previous icon with the iOS 18 SDK, I didn’t have any issues uploading it. However, when I created the new icon with Icon Composer and compiled it with Xcode Beta, it broke. I’m a bit confused because the error message suggests that removing transparency is the solution, but the whole point of Icon Composer is to make the icon transparent for the new liquid glass design. I don’t want to remove the cool look that my new transparent icon has. Could you please help me out? I’d really appreciate it. Thanks a bunch!

Hi, I'm using one ttf font that simulate a bitmap look in my app. However, macOS renders all font with anti-aliasing. On those kind of font, that introduce some artefacts. Is there a way to disable anti-aliasing or some tricks that would make like there were no anti-aliasing? Thanks.

I am trying to use SpeechDetector Module in Speech framework along with SpeechTranscriber. and it is giving me an error Cannot convert value of type 'SpeechDetector' to expected element type 'Array.ArrayLiteralElement' (aka 'any SpeechModule') Below is how I am using it let speechDetector = Speech.SpeechDetector() let transcriber = SpeechTranscriber(locale: Locale.current, transcriptionOptions: [], reportingOptions: [.volatileResults], attributeOptions: [.audioTimeRange]) speechAnalyzer = try SpeechAnalyzer(modules: [transcriber,speechDetector])

I've noticed that in iOS 26, Navigation Bar Items' Image Insets parameters as set in Xcode are not being read correctly. Specifically, it appears that on iOS 26 beta, negative inset numbers are being read as positive. Feedback report FB19838333 includes a sample project demonstrating this bug.

I'm experiencing some rare crash but only if I enable Xcode's "thread performance checker". The crash typically ends with these lines: std::_1::hash_table<std::_1::hash_value_type<long qosWaiterSignallerInvariantCheck ... and sometimes with "findPrimitiveInfoNoAssert" on the second line. I wonder if I am doing anything wrong, or is it a (hopefully known) issue in thread performance checker itself? It does look like some sort of data race bug, if to guess there's some internal dictionary that's not properly protected with a mutex or something. I'm using Xcode 16.4 running on macOS 15.5, building and running an app on iPhone with iOS 18.5. Cheers!

Hi guys! I have gone through an absolute nightmare, trying to solve the issue that I am about to tell you about. As the title says, I am getting the error: Library '/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/17/lib/darwin/libclang_rt.profile_driverkit.a' not found I trimmed off part of that directory as I did not want to reveal that information about my computer. From what I can tell, the file in question is no longer even a part of Xcode. I have searched, it is not on my computer anywhere. I have also downloaded older versions of Xcode to search with it. None of them have it. I have literally tried everything under the Son to solve this issue. I have been stuck on it for two days. I have even resorted to doing something I hate, which is asking for ChatGPT to assist me with solving the issue. No help there. I am at my wits end. So I am coming to you guys, have you seen this error? Any ideas at all? The odds are pretty good whatever you recommend I have probably already tried 200 times over. But I am still open to hearing anything. Have any of you had this error? Any ideas? I am on the latest version of macOS. The project is for a macOS app. M4 Mac mini. Any additional information I can provide, that will be helpful? At this point, I am leaning more towards this being a bug with Xcode than anything.

Hello 👋 I would like change my username for several reason. Is there a way to change it ? I don’t want to create an another Apple account just for that. Have a nice day 😁

Helllo, I'd like to change my username. Is there a way I can do that? The one I have is one I made by accident and I would prefer not to create an entirely new apple account.

Hi, This can't be right. Is there really no replacement for Quartz Debug?!? As the sole developer on a project who has an Intel Mac and Quartz Debug, I am basically a god now. Everyone else has Apple Silicon and... I think they're randomly guessing at this point. Because I have entire teams sending me Intel Mac builds of stuff just so I can test it in QD. This is THE TOOL we used at NewTek to find performance issues, and THE TOOL I used for a dozen companies after that, to help them with similar issues. If there's no replacement, is there a reason there's no replacement? This feels like a massive step backwards, having to guess at problems like this. -Chilton

I’m running into unexpected problems with the Unity GameKit plugin setup with the new Activities. I didn’t see anyone else mentioning these issues, so my guess is that it’s a problem with my setup. The authentication (GKLocalPlayer.Authenticate()) works as expected, but any call to the new GameActivity functionality (e.g. GKGameActivityDefinition.LoadGameActivityDefinitions() or GKGameActivity.WantsToPlay) gives me an exception with a 'UnsupportedOperationForOSVersion' reason despite it running on an iOS 18.6.1 device. I’m using a completely empty Unity 2022.3.62f1 project that only contains the official authentication example, followed by an event handler for activities from another example and the Unity core and gamekit plugins. The setup: macOS 15.6 Xcode 26 beta 6 (also tried with 5) Physical iPhone device running iOS 18.6.1 Unity 2022.3.62f1, which satisfies the requirements Unity plugin, Xcode setup, and build steps: I Followed the official beta branch build steps for Unity plugins with python3 build.py -m iOS iPhoneSimulator macOS -p Core GameKit which ran through after a slight modification for the macOS target that somehow contained an unknown team reference for the GameKitWrapper project, which I changed to not reference a team and use ‘sign to run locally’, as was the case for the other packages. As far as I understood the macOS version is not strictly necessary either way just for running it on a local iOS device(?) I Imported these as tarball packages into the empty Unity 2022.3.62f1 project as per the official instructions, which seems to work as expected Added a single script with the mentioned example code added in a MonoBehavior.Start Building in Unity works as expected as well, creating the Xcode project The Unity-iPhone target has the GameKit framework linked (’do not embed’) and the GameCenter capability was added automatically as expected The GameKit framework seems to not be added to the UnityFramework target, but I don’t think this is necessary? Quickly testing this with the GameKit framework added there as well didn’t make a difference The linked GameKit framework is indeed the expected Xcode 26 beta version I can then build and run this on the physical iPhone iOS 18.6.1 device, where I get an ‘UnsupportedOperationForOSVersion’ as soon as I try to subscribe to deeplinking events (GKGameActivity.WantsToPlay) or use other GameKit Activity functionality from the official examples: // log showing that it's actually running on iOS 18.6: [Apple.Core Plug-In Runtime] Availability Runtime Environment: iOS 18.6 Apple.Core.Availability:OnApplicationStart() // and the exception I get: GameKitException: Code=-7 Domain=GKErrorDomain Description=The operation couldn’t be completed. (GKErrorDomain error -7.) (UnsupportedOperationForOSVersion) at Apple.GameKit.DefaultNSErrorHandler.ThrowNSError (System.IntPtr nsErrorPtr) [0x00000] in <00000000000000000000000000000000>:0 Rethrow as TypeInitializationException: The type initializer for 'Apple.GameKit.GKGameActivity' threw an exception. I unfortunately didn’t find any clues as to why this happens and how to resolve it on this forum or otherwise. Changing the minimum iOS version - up to 18.6 from the previously used (Unity export default) 12.0 for any and all targets - did not yield a different result I'd rather not update the phone to use the iOS 26 beta, though as far as I understood this is not necessary Any pointers to what I might be missing or doing wrong are greatly appreciated! Thank you very much in advance!

When I create a sticker app in any version of Xcode or for any iOS version, I keep running into the following error: Error acquiring assertion: <Error Domain=RBSAssertionErrorDomain Code=2 "Could not find attribute name in domain plist" UserInfo={NSLocalizedFailureReason=Could not find attribute name in domain plist}> I only added stickers after creating the project and this is what happens after running it. I have cleared Derived Data, tried creating a new Info.plist, but nothing seems to solve this core issue. This also occurs both when attempting to run the project on a simulated phone and a physical device. This error also only happens when the sticker app is opened in iMessage. I have looked for solutions everywhere, but none seem to solve my problem. Am I overlooking something?

Hello everyone, I am currently developing an iMessage Sticker Pack in Xcode 16.4 (Build 16F6) on macOS 15.6.1. The project builds without errors, but when running in the iOS 18.6 Simulator (iPhone 15 Pro, iPhone 16, etc.), the Sticker Pack does not show up inside Messages. Instead, the Simulator displays a white screen or the sticker drawer simply does not include my extension. In the logs I consistently see this error: FrontBoard[app] error: Application "de.eazyapp.smileystickerpack.StickerPackExtension" is unknown to FrontBoard Simulator device failed to launch de.eazyapp.smileystickerpack.

Since adding the ios26 beta, I can no longer connect to iMessage using my phone number. It connects using email addresses but, when trying to connect to my phone number, it just gives me the buffering signal and never connects. I am on Beta 4 and still no joy. Help! I have become a green bubbler!!

I’ve got the new SwiftUi webview in a sheet. When I pull down the contents from the top of the page I expect it to dismiss the sheet, but it does not. Is there a workaround or modifier I’m missing?

I have managed to configure Apple Intelligence in Xcode to access my deployed models in Azure AI Foundry. However, when I would try to chat with the selected model, I get the following error: Message from Azure OpenAI: Failed request due to: bad request Additional context: {"error": {"code": "BadRequest", "message": "Response API v1 is in GA, please use remove api-version or use api-version=latest."}} Is there a way to remove v1 from the endpoint used or to define an explicit api-version? Or do I have to change my deployment in Azure AI Foundry?

When I add a TextField with @FocusState to a toolbar, I noticed that setting focus = false doesn't cause the form to lose focus If I move the TextField out of the toolbar setting focus = false works fine. How can I unfocus the text field when the cancel button is tapped? Minimal example tested on Xcode Version 26.0 beta 6 (17A5305f): import SwiftUI struct ContentView: View { @State private var text: String = "" @FocusState private var focus: Bool var body: some View { NavigationStack { List { Text("Test List") } .toolbar { ToolbarItem(placement: .bottomBar) { TextField("Test", text: $text) .padding(.horizontal) .focused($focus) } ToolbarItem(placement: .bottomBar) { Button(role: .cancel) { focus = false // THIS DOESN'T WORK! } } } } } } #Preview { ContentView() }```

We have two sets of screenshot images for 5.5 and 6.5 displays of the iOS app which needs a new version. When I first uploaded the screenshot set for the 6.5 display, it looks all good. Then I uploaded another set for the 5.5 display and headed back to check 6.5 images. I found some of them reported errors IMAGE_TOOL_FAILURE. Then I deleted all 6.5 screenshots, re-uploaded for the 6.5 display again. However, this time 5.5 had errors. It is like a loop. I tried tens of times. And, if I upload 6.5 first, it all looks good. And then I go to another tab, for example, the app information tab and then come back. I also find the images are marked as 'The file has been uploaded and is processing ' .

Hi everyone, When I try to upload screenshots, they turn into red exclamation marks after I refresh the browser page. Anyone else having the same issue?

Hi all, I'm trying to install the Xcode 26 beta on Tahoe (M4 Mac mini). I tried the latest beta 6 both the universal and the apple silicon version, but at startup the system says the app is corrupted and will be deleted. I tried this multiple times - always with a fresh download. Then I downloaded the beta 5, which told me at startup that there is no macOS SDK available and then Xcode also quits. I want to update/test my macOS apps for the upcoming Tahoe and want to adapt for the new design. On my Mac is the Xcode version 16.4 installed and this is working correctly. In the last years I started with earlier versions of Xcode betas, but this year I'm a little bit more late. Are there any steps I missed or is this a known issue yet? I had never before so much trouble installing any beta. What can I do? Best regards, Jürgen Terpe

I was trying to watch hulu while on facetime and saw theres no way to change the screenshare/shareplay automatically like you can set it to on the other ios and not automatically shareplay hulu on ios 26 beta unless i just didnt see it.
