"Could not install [App Name]. The requested app is not available or doesn't exist." when installing app from TestFlight
Hello Apple Developer Support, We are experiencing an issue with TestFlight Internal Testing. Our internal testers can see the app and the assigned build in the TestFlight app, but when they try to install it, the installation fails with the following error: Could not install [App Name]. The requested app is not available or doesn't exist. This issue happens with Internal Testing, so Beta App Review should not be involved. We have already checked the following: The build was uploaded successfully through Xcode using App Store Connect distribution. The build processing is completed. The build is assigned to the correct Internal Testing group. The testers are added as App Store Connect users and have access to the app. The app appears in TestFlight for the testers. Agreements, Tax, and Banking do not show any pending actions. Export Compliance / Missing Compliance does not show any pending actions. The issue happens on multiple devices. We have tried removing and reinstalling TestFlight, and uploading

Reply to CarPlay voice-based-conversational app crashes when CarPlay scene activates before phone scene (React Native + Expo)
Thanks for the post. It appears that your project utilizes React-Native. Regrettably, I lack experience with this third-party development tool as I’m focused on native development with Apple authored tool like Xcode. You should check with the support resources provided by the 3rd party to get assistance with their software. Unless another developer in the forums has experience with the third-party and can provide assistance. Albert

Reply to Xcode now hangs; SDKs are "status unavailable"
Success! Xcode 26.5 Release Candidate (17F42) running on macOS Tahoe 26.5 Release Candidate (25F71) appears to have fixed the problem for me. I first updated to macOS 26.5 RC, and then to Xcode 26.5 RC. I didn't need to clean out my previous installation data (e.g., /Library/Developer, etc.) ... I just deleted my 26.4.1 Xcode and replaced it with the new. My simulators showed up as expected. I did several reboots of my computer, and each time, the simulators briefly show as status unavailable but then they eventually show up and stay there. Hopefully, others have the same the same success.

Xcode now hangs; SDKs are "status unavailable"
My development work is paused as Xcode is now non-functional on my Macs. Loading any project into Xcode soon leads to a hang and Force Quit. The SDKs are listed as status unavailable. No Simulators are available. I've tried previous versions of Xcode; removing everything and re-installing; installation from the Store and direct from the Apple Developer site. I've created a Feedback issue. This happens on both of my Mac minis. I'm running Tahoe 26.4 (25E246) on both.

Reply to Installing an App on a single device, no app store
Thanks for the post. You can just compile the app and press play to install into your device. If you don't mind plugging your phone into your Mac is the most private and lowest-maintenance route https://developer.apple.com/documentation/xcode/running-your-app-in-simulator-or-on-a-device However, since you need it to run in production mode and you want to keep your code and credentials secure, Ad Hoc distribution allows you to export a production-ready version of your app. You register your iPhone/iPad's unique identifier (UDID) in your Apple Developer account. When you build the app, you create an Ad Hoc provisioning profile that includes your device. You can install the resulting .ipa file directly onto your device by plugging it into your Mac and dragging the file into your device via Finder, or by using the Apple Configurator app. TestFlight is for beta testing. While it is associated with App Store Connect, Internal Testing, and the app remains completely hidden from the public. You upload the ar

@DTS Engineer We should update the app to this version. Please review the full list of changes—you can find it here: https://developer.apple.com/documentation/xcode-release-notes/xcode-26_5-release-notes Also, please check the same issue reported in the Xcode 26 release candidate: https://developer.apple.com/forums/thread/799757 We need to ensure that all required Xcode versions are supported so developers can successfully upload code for a single app update using the latest SDK. Please confirm if we should proceed with the update. Best regards,

Reply to Can not upload using Xcode 26.5 release candidate
Thanks for the post, yes, the release candidate is not marked for submitting to the App Store on the release notes. Yes, this is a very normal and well-documented App Store Connect error. App Store Connect has strict rules about which versions of Xcode and Apple SDKs can be used to submit apps. This error triggers when you try to upload an app built with a version of Xcode (or an iOS/macOS SDK) that Apple’s servers do not currently accept for App Store distribution. If you are using a beta version or an RC that hasn't officially opened the gates for yet, you will get this exact rejection. Look at the release notes for that build https://developer.apple.com/documentation/xcode-release-notes/xcode-26_5-release-notes Albert

SKStoreReviewController requestReviewInScene: does not display review prompt in debug builds on iOS 26.5 beta (23F5043k)
[SKStoreReviewController requestReviewInScene:] no longer displays the review prompt in debug/development builds on iOS 26.5 beta (23F5043k and 23F5043g). According to Apple's documentation, the review prompt should always appear in debug builds to facilitate testing. This was working in previous iOS versions (iOS 26.4 and older). Steps to reproduce: Run app from Xcode in debug configuration on a device running iOS 26.5 beta (23F5043k or 23F5043g) Call [SKStoreReviewController requestReviewInScene:windowScene] with a valid, foreground-active UIWindowScene Observe that the method executes without error (scene is valid per NSLog) but no review prompt appears Expected: Review prompt should display in debug builds Actual: No prompt appears, despite the scene being valid and foreground-active This worked correctly on previous iOS versions (26.4) so looks like this bug was introduced in 26.5 Beta versions. I have already filed a bug report in Feedback Assistant with number: FB22445620

Reply to Building macOS apps with Xcode 26 on macOS 26 VM
Does this only work when using a personal team? I've just tried a near-identical setup - Virtual Buddy 2.1, Xcode 26.5 RC, Tahoe 26.5 beta (not the latest). I'm still getting Device My Mac is not registered to your team... in XC on the VM. It says I do not have permission to register them, but I'm signing in with a developer account that has admin rights for the team in question. I'm signing in to the VM and Xcode with the same Apple ID fwiw. The app I'm testing uses iCloud and so I can't test it using a personal team.

AVMutableComposition audio silently drops on iOS 26 when streaming over HTTP/2 (FB22696516)
We've discovered a regression in iOS 26 where AVMutableComposition silently drops audio when the source asset is streamed over HTTP/2. The same file served over HTTP/1.1 plays audio correctly through the same composition code. Direct AVPlayer playback (without composition) works fine on HTTP/2. This did not occur on iOS 18.x. It happens on physical devices only. It does not reproduce on a simulator or on macOS. Tested conditions (same MP4 file, different CDNs): CloudFront (HTTP/2) + Composition → ❌ Audio silent Cloudflare (HTTP/2) + Composition → ❌ Audio silent Akamai (HTTP/1.1) + Composition → ✅ Audio works Apple TS (HTTP/1.1) + Composition → ✅ Audio works Downloaded locally, then composed → ✅ Audio works Direct playback, no composition (HTTP/2) → ✅ Audio works The CloudFront and Akamai URLs serve the identical file — same S3 object, different CDN edge. CDN vendor doesn't matter; any HTTP/2 source triggers it. Minimal reproduction: let asset = AVURLAsset(url: http2URL) let videoTrack = try

Need help to build a Mac command-line app for App Store or TestFlight
I have a binary that successfully install & run on my Mac, that is build with codesign and pkgbuild with Developer ID Application and Developer ID Installer identities. I cannot figure out how to transform this pkg into a distribution package that fits with App Store and TestFlight. Xcode builds it fine and can run it seemingly, but cannot provide the App Store Distribution option in Organizer after creation of Archive. (Only Custom option.) I probably may not be able to specify properly the build Target as Release (don't know where to specify). (pkgbuild ->) productbuild -> Transporter is also an option, but don't know how to properly specify the productbuild --component options... I have a developer program and can generate the Apple developers certificate fine, such as 3rd Party Mac Developer Application/Installer. A pkg codesign'ed by them was rejected by the notarization process. My application is C and can be started again as New project from Xcode as MacOS Command-Line Tool,
