I am trying to integrate fastlane, which relies on xcodebuild. So this is my first experience with xcodebuild. Whenever I run a command to test or build the target in the folder where all the files of the project are stored, the action failes with Unable to find a device matching the provided destination specifier For example I might be running this command: xcodebuild \ -project Hoerspielzentrale.xcodeproj \ -scheme HoerspielzentraleUITests \ -destination 'platform=iOS Simulator,name="Screenshot Simulator”' \ test However the mentioned error is returned: xcodebuild: error: Unable to find a device matching the provided destination specifier: { platform:iOS Simulator, OS:latest, name:"Screenshot Simulator” } The requested device could not be found because no available devices matched the request. I can confirm that the simulator exists, is available and it can be booted. I have tried different simulators, different schemas, referencing them by their identifier, switching Xcode Versions, reset all simulators, derived data and build folder. After the error a complete list of all available destinations can be found, where I can see the simulator I try to use. Available destinations for the "HoerspielzentraleUITests" scheme: { platform:iOS, id:dvtdevice-DVTiPhonePlaceholder-iphoneos:placeholder, name:Any iOS Device } { platform:iOS Simulator, id:dvtdevice-DVTiOSDeviceSimulatorPlaceholder-iphonesimulator:placeholder, name:Any iOS Simulator Device } { platform:iOS Simulator, id:961DC569-9931-419A-B46E-769AAFA73EA2, OS:18.5, name:Screenshot Simulator } { platform:iOS Simulator, id:961DC569-9931-419A-B46E-769AAFA73EA2, OS:18.5, name:Screenshot Simulator } { platform:iOS Simulator, id:5E51FD98-C451-472F-9CDE-08D49E6B737B, OS:18.5, name:Screenshot Simulator Pro } { platform:iOS Simulator, id:5E51FD98-C451-472F-9CDE-08D49E6B737B, OS:18.5, name:Screenshot Simulator Pro } The rest of the list was omitted. I am currently completely stuck. Thank you

I've been experimenting with using local LLMs in place of ChatGPT in coding assistant. I was able to do this using LM Studio. I found that switching LLMs was a little clunky, but eventually, I was able to make it work. However, none of the LLMs I tried were able to generate error free Swift code. Not surprising at this stage. I decided to train an LLM (Llama3.1-8b) with Apple's Swift Programming language reference, using Open WebUI, and this worked. I was able to get the LLM to generate working Swift Code that I was able to test in Playgrounds. The problem I'm having now is that Xcode is locked up on the last LLM I tried out. I've tried deleting all the LLM providers in Settings, leaving only ChatGPT, but Xcode still defaults to the local LLM, even though it throws errors if you try to ask it a question. I've tried reinstalling Xcode, downloading new versions of sample Xcode projects, and deleting various data files, all to no avail. I would really like to test the new LLM I've trained in coding assistant, but right now, Xcode won't let me. It won't even let me revert to ChatGPT.

Hi all, Im trying to upload an app to the App Store, the app is made in Unity, well I built the app there and then open the Xcode project, from there set some fields and now when I have to go to Product>> Archive I get an error always, could you please tell me what is this and how to fix? unsupported option -mno- thumb for target arm64-apple-ios 15.6 Im using Xcode 16.4 which I think is the latest version released. Thanks for any clue about this, Im really lost

Is there a way to permanently disable PHASE SDK logging? It seems to be a lot chattier than Apple's other SDKs. While developing a RealityKit app that uses AudioPlaybackController, I must manually hide the PHASE SDK log output several times each day so I can see my app's log messages. Thank you.

Hello, I'm getting this error when launching a SpriteKit Swift game in iOS 18+ on an iPhone 11 Pro, whose shell is partly damaged in the back: CHHapticEngine.mm:1206 -[CHHapticEngine doStartWithCompletionHandler:]_block_invoke: ERROR: Player start failed: The operation couldn’t be completed. (com.apple.CoreHaptics error 1852797029.) Haptics do not work on this device, due to the damaged shell, so some error — which obviously occurs when calling start(completionHandler:) — is definitely expected; what is not expected is the main thread sometimes blocking for up to 5 seconds — although the method is not called from the main thread... the error itself is always displayed from some other secondary (system) thread. During this time, the main thread does not access the haptics engine at all; on average, it blocks once every four or five launches. In each launch (blocking or not), the 'nope' error is displayed ~5 seconds after trying to start the engine. After going nuts with all kinds of breakpoints and instrumentation, I'm at a loss as to why the main thread would sometimes block... Ideas, anyone? Thank you, D.

A method in my app now requires the override keyword when compiling with Xcode 26 beta / iOS 26 SDK, but if I add it, the current official Xcode 16.4 (iOS 18 SDK) throws a compile error. It's about 'toggleSidebar(_:)' in UIViewController. The problem is: Apple expects our apps to be ready for iOS 26 launch this fall, so I need to be actively developing and testing in the Xcode 26 beta now. At the same time, I still need to submit updates to the App Store using the current official Xcode 16.4 until iOS 26 officially launches. I'm using a single .xcodeproj file and can't keep manually adding/removing -DIOS_SDK_26_OR_LATER in Build Settings multiple times a day. How to fix it and why isn't there a straightforward #if sdk(>=26.0) type of check for compile-time in Swift? It's really frustrating to manage this override conflict.

Crash while trashing an opened and pinned file. This crashing can be reproduced. Xcode Version 26.0 beta 2 (17A5241o) Part Of Crash Log

We use several UIKit and AVFoundation APIs in our project, including: setAlternateIconName(_:completionHandler:) getAllTasks(completionHandler:) loadMediaSelectionGroup(for:completionHandler:) Moreover, we use the Swift Concurrency versions for these APIs: @MainActor func setAlternateIconName(_ alternateIconName: String?) async throws var allTasks: [URLSessionTask] { get async } func loadMediaSelectionGroup(for mediaCharacteristic: AVMediaCharacteristic) async throws -> AVMediaSelectionGroup? Everything worked well with these APIs in Xcode 16.2 and earlier, but starting from Xcode 16.3 (and in 16.4), they cause crashes. We've rewritten the APIs to use completion blocks instead of async/await, and this approach works. Stack traces: setAlternateIconName(_:completionHandler:) var allTasks: [URLSessionTask] { get async } loadMediaSelectionGroup(for:completionHandler:) Also, I attached some screenshots from Xcode 16.4.

XCode 26 beta 2 is taking more than 20 seconds to start AVCaptureSession when AVCaptureVideoDataOutput and AVCaptureAudioDataOutput are added. The problem occurs only during debugging and is clearly seen with Cinematic Capture sample code by Apple. I am using iPhone 14 Pro running iOS 26 beta 2 for reference.

I’m updating my app’s alternate icons using UIApplication.shared.setAlternateIconName, and I noticed that in iOS 26, Xcode now supports the new .icon file format for App Icons. Is it possible to reference .icon files directly for alternate icons? Or does setAlternateIconName still only support traditional .png assets inside the AppIcon set? I couldn’t find any documentation confirming this either way, and I want to ensure compatibility with the new format while supporting alternate icons. Any clarification or Apple documentation link would be greatly appreciated!

I'm developing a visionOS app and was able to upload new builds without any problems to the App Store. A couple pf days ago I wanted to ship another update, but now I can't submit it to the App Store anymore, because the validation failed, something related to the App Icon seems to be the issue, the logs mention CFBundleIcons.CFBundlePrimaryIcon. I have setup the App Icons here: The validation error I first got was this, mentioning a plist entry (that has not been necessary in the past) is missing. I've then added that plist entry, as described in the reference doc for CFBundleIcons.CFBundlePrimaryIcon. My info.plist now includes this, following the mentioned docs: However, now I get a type missmatch error when validating — however the types are as described in the docs: What am I missing? Why even is this plist entry required now? Or is this a Bug? Help please

error I get when I try and install predictive code completion model

Last week I bought an M4 Pro Mac mini with 24GB RAM to use as my “beta testing” machine. I don’t want to use my main machine for beta OS testing, so figured this config would be perfect for that. However, there have been several times when running Xcode 26 on macOS Tahoe, along with a simulator or two, that memory pressure has gone up into the “yellow” and keeps increasing. I am surprised that 24GB doesn‘t seem like enough RAM. I don’t have giant projects or use anything else on this machine. It’s pretty simple stuff. Maybe this is to be expected with betas: memory leaks, non-optimized code, etc. I’m considering returning the machine while I can. What do others find is a good amount of RAM for fairly modest development needs?

Good day! I have a long-term project ported all the way up from old Think C through many versions of Xcode. Its source files are encoded in "Western (Mac OS Roman)". Some of my error messages have characters outside the straight ASCII character set (i.e. "å"). The editor correctly displays these, but I get plenty of Illegal Character warnings and the messages do not display properly. I imagine there's a way to have seperate files of localized text for internationalized applications, but I am the only end-user of this application, and it used to just plain work in earlier Xcode versions. Furthermore, there must be developers throughout Europe who use such characters in string literals, just typing in their native languages, straight off their keyboards. I was thinking that there must be a Clang setting or something, but have been unable to find it, and an internet search turns up no solution except to cumbersomely escape each individual character. I can't imagine that a French programmer does that every time they want to type "è", "é", or "à"! Any help? (Disclaimer: I'm an English speaker and only use such characters whimsically, but want to keep them for legacy's sake.) Thanks.... p.s. using Xcode 15.3, and under Settings->Text Editing->Editing, "Western (Mac OS Roman)" is already selected as the default text encoding with "Convert existing files on save" checked.

I have this build error with Xcode 26 beta 2: var asset:AVURLAsset? func loadAsset() { let assetURL = URL.documentsDirectory .appendingPathComponent("sample.mov") asset = AVURLAsset(url: assetURL, options: [AVURLAssetPreferPreciseDurationAndTimingKey: true]) /*Error: Type of expression is ambiguous without a type annotation */ if let result = try? await asset?.load(.tracks, .isPlayable, .isComposable) { } } Is there an issue with try? in the new Swift compiler? Error: Type of expression is ambiguous without a type annotation

We are working on a Unity iOS app for the App Store. We are working with different SDKs and plugins(Firebase, Facebook, CleverTap, AVpro, DTT, etc ). We can make an Xcode export build from Unity for the iOS platform.

Hi, in our Xcode project we have a Tooling package, which defines build tool plugins for generating compile time safe constants for our localization strings as well as assets using swiftgen. This is working very well in Xcode 16, but fails in Xcode 26 beta 1 and beta 2 as well. The failure is specifically: unsupported configuration: the aggregate target 'Localization' has package dependencies, but targets that build for different platforms depend on it. I've reduced this to a minimal sample project, which you can find here.. To reproduce: Open the Repro workspace, that is attached in Xcode. Try to build TestyPackage. You'll see the error. I've filed this bug during WWDC week, but no feedback yet and no solution in Xcode 26 beta 2. Here's the feedback number, in case you have this too and want to file a duplicate: FB17934050. Does anyone else have this issue and perhaps a solution?

Hi everyone, I’m running into an issue trying to use the new SpeechAnalyzer framework announced at WWDC 2025. ❯ My Setup: • macOS: Sequoia 15.5 (Build 26.0 / macOS Tahoe Beta 26.0) • Xcode: 26.0 beta 2 (17A5241o) • Deployment Target: macOS 26.0 • Toolchain: Clang 17.0.0 (Apple) ❯ Problem: Despite following all setup requirements: • Setting macOS 26 as the deployment target • Using the latest Xcode 26 beta 2 • Running the correct developer toolchain (xcode-select is pointing to Xcode-beta) I still get the error: No such module 'SpeechAnalyzer' Additionally: • The SpeechAnalyzer.framework does not appear under /Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ • It is also not listed in the Link Binary with Libraries pane. ❯ What I’ve Tried: • Clean builds • Deleted DerivedData • Verified SDK installation paths • Reinstalled Xcode 26 beta 2 • find search for SpeechAnalyzer.framework returned nothing ❯ Request: Has anyone successfully used SpeechAnalyzer in Xcode 26 beta 2 on macOS Sequoia/Tahoe? Is there a separate SDK or seed profile required to access this framework? Would appreciate any guidance from Apple engineers or other beta testers. Thanks! — Lalit Lakhara

Why is "generate comment" button grayed out?
