xcode github

Hi, I’m working on my Swift Student Challenge submission using iOS 26 APIs (FoundationModels) along with AVFoundation + Vision to capture user input and generate feedback. Since Swift Playgrounds doesn’t support FoundationModels framework, I’m using an Xcode App Playground, but I heared that submissions are reviewed in the Simulator, which doesn’t support live camera feed. I’m unsure how to handle this. Looking for guidance on the recommended approach. Thanks!

Code is download from apple official metal4 sample [https://developer.apple.com/documentation/metal/drawing-a-triangle-with-metal-4?language=objc] enable metal gpu trace in macOS schema and trace a frame in Xcode. Xcode may show segment fault on App from some 'GTTrace' function when click trace button. When replay a .gputrace file, Xcode may crash , throw an internal error or a XPC error. The example code using old metal-renderer can trace without any problem and everything works fine. Test Environment: Xcode Version 26.2 (17C52) macOS 26.2 (25C56) M1 Pro 16GB A2442

I am trying to create a new Xcode project. I am unable to open or create a new project, and am getting the error message You don't have permission to save the file... in the folder... and Authentication failed because the credentials were rejected. I have confirmed I am signed in with the correct Apple ID. I have also confirmed through Xcode account settings, my account is in my organisation team, and I have an Apple Development Certificate and an Apple Distribution Certificate, both created 20/11/2025 (no status listed for either). Could someone please help?

Hi, I'm trying to figure out what is true here - if I am not in the correct forum please direct me :-) A. It is not possible to test a QR code scan that contains a deeplink into my iOS app from an XCoode build test run. In other words, The build must be published to Test Flight for the iOS's QR code scan sub-system to be able to process the deeplink into my app? If I am wrong about this, it sure would help with testing to be able to test directly from the local XCode build test. If so, can someone point me in the direction of what I would need to do for that? Thanks for your input either way!

I'm implementing the in app provisioning in a financial project. I got my entitlement identifier, I'm also implementing the wallet extension but I have the problem with Xcode. Domain: IXUserPresentableErrorDomain Code: 1 ... NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. But I'm not sure what does this mean, I reviewed the info.plist form the project and the wallet extension

I've signed an app, zipped it, and uploaded it to github. When I download it on another Mac, I get it can't be opened because it could not be verified for malware. But on that computer, I can verify it with codesign, and it appears to be correct (as far as I can tell). I can copy/paste the app from my other Mac, and that copy will run without problem. sys_policy, however, gives: Notary Ticket Missing File: ReView.app Severity: Fatal Full Error: A Notarization ticket is not stapled to this application. Type: Distribution Error This is the same for the copy that runs, and the copy that doesn't. The difference between them appears to be a quarantine xattr. I can delete this, and the app launches without incident. Is this expected? Why should a signed app be quarantined just because it's been downloaded? The whole point of paying the fee is to avoid the security obstacles...! ;-)

Hi there, I have an SwiftUI app that opens a user selected audio file (wave). For each audio file an additional file exists containing events that were extracted from the audio file. This additional file has the same filename and uses the extension bcCalls. I load the audio file using FileImporter view modifier and within access the audio file with a security scoped bookmark. That works well. After loading the audio I create a CallsSidecar NSFilePresenter with the url of the audio file. I make the presenter known to the NSFileCoordinator and upon this add it to the FileCoordinator. This fails with NSFileSandboxingRequestRelatedItemExtension: Failed to issue extension for; Error Domain=NSPOSIXErrorDomain Code=3 No such process My Info.plist contains an entry for the document with NSIsRelatedItemType set to YES I am using this kind of FilePresenter code in various live apps developed some years ago. Now when starting from scratch on a fresh macOS26 system with most current Xcode I do not manage to get

I'm new to Xcode. I just downloaded version 26.2 and I'm working on an iMac with macOS Sequoia 15.7.3. I'm created a playground with some very simple code and it crashes when I click live view. I tried looking all over online for a solution and nothing has worked. I tried uninstalling and reinstalling Xcode and still have the same problem. When running the code with the console open I do see the following error. objc[19786]: Class _TtC16AppIntentSchemas16AppIntentDomains is implemented in both /System/Library/PrivateFrameworks/AppIntentSchemas.framework/Versions/A/AppIntentSchemas (0x2840a4c28) and /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/AppIntentSchemas.framework/Versions/A/AppIntentSchemas (0x3276359e8). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. I went to the first folder mentioned in the error /System/Library/PrivateFrameworks/AppIntentSchemas.framework
