Reply to TestFlight on Mac
Thanks for the post. I believe the issue you're encountering stems from attempting to install an iOS app build, even though it's marked as Designed for iPad, on a Mac. While Apple Silicon Macs can run iOS and iPadOS apps natively, there are nuances in TestFlight's handling of these builds that might cause installation issues if not configured correctly. I am not in the TestFlight team so I need to make sure this is the most accurate answer, I have invited the TestFlight team to post their answer in this thread however, they are not actively monitoring the forums. To make sure, ensure that the build settings in Xcode explicitly support macOS as a destination under Supported Destinations or via Universal Control settings for Apple Silicon. Open your Xcode project. Navigate to your target settings, and under the General tab, ensure that Deployment Info specifies iOS as the platform. For Universal apps, make sure Supported Destinations includes My Mac (Designed for iPad) if you specifically inte

TestFlight on Mac
I’m having an issue installing my TestFlight build on a Mac. The build (v1.0 build 1) uploads successfully and shows as “Complete” in App Store Connect. I can also open the build details page, and my Apple ID / tester access / group setup looks correct. However, on TestFlight (macOS), when I tap Install/Load, I get this error: Unable to install. The requested app isn’t available or can’t be found. Notes: The app is an iOS app (iPhone + iPad), and I enabled availability for Mac (Designed for iPad) in App Store Connect. The Mac is Apple Silicon, running macOS Tahoe 26.1. Could you help me understand why TestFlight shows this message on Mac, and what I should change in Xcode/App Store Connect to make the build compatible?

Reply to How to remove "Developer ID Application" certificate?
Then Xcode shouldn't just add dupes of these certs. What happens is signing fails, Xcode gives no guidance. And so the Xcode UI has the option to add a new one. Then end up with dupe certs that cannot be cleaned out. Then the profiles fail if not the correct out of the 3 dupes, and signing still fails if the cert private key isn't in the keychain. Again no guidance from Xcode on any of these signing failures. Here's one error. Xcode shows Ineligible for the profile: Provisioning profile KramViewerProvision doesn't include signing certificate Developer ID Application: ... (hash...) Here's an error when the private key isn't in the Keychain. C6BA06....: no identity found Command CodeSign failed with a nonzero exit code

Reply to Create a new GitHub Remote Repository - Unknown Error
Thank you for the post. It appears that the issue is related to GitHub rather than Xcode. However, the error message could be more descriptive. Experiencing issues when trying to create a new remote GitHub repository from Xcode can be frustrating, especially when other functionalities are working fine. Can you go to the GitHub website and create the repository manually on their website? Ensure that your GitHub account has the appropriate permissions to create new repositories. You might want to try logging into GitHub via a web browser to verify your account status or as previously wrote, try to create the repo on their website and then just reference the link on Xcode. Manually Create on GitHub Website: Create the new repository directly through the GitHub website. Afterward, in Xcode, add this remote repository by going to or using the Terminal commands shown in advanced diagnostics to push your existing local

Reply to App Store Connect rejects screenshot upload: “incorrect size” (subscription purchase flow) — tried all documented sizes
Welcome to the forums. So just select a simulator in Xcode for iPhone and iPad (e.g., iPhone 16 Plus 6.7 and iPad Air 13) and run the app on them. The screenshots generated by the simulator (cmd-S) will provide the right sized images. Note that you have to provide only one size for iPhone and one size for iPad.

Reply to DNS Proxy system extension – OSSystemExtensionErrorDomain error 9 “validationFailed” on clean macOS machine
Thanks for the clarification about Developer ID vs Apple Development and for the links. Previously I started with Developer ID and the dns-proxy-systemextension entitlement, but per your advice I’ve now switched both the host app and the DNS Proxy system extension to Apple Development signing and the legacy dns-proxy value. Current Apple Development setup macOS: 15.7.3 (24G419) Xcode: 26.2 (17C52) Host: com.example.agent.MyMacProxy DNS Proxy system extension: com.example.agent.MyMacProxy.dnsProxy System extension entitlement: xml com.apple.developer.networking.networkextension dns-proxy System extension Info.plist (built .systemextension inside the host app): xml NSExtension NSExtensionPointIdentifier com.apple.system_extension.network_extension NSExtensionPrincipalClass MyMacProxy.DNSProxyProvider There is no NetworkExtension key in this plist (confirmed with plutil -p on the built .systemextension in both DerivedData and /Applications). The system extension is embedded at: MyMacProxy.app/Contents/L

Reply to Reduce dyld overhead
OK. I don’t think you can optimise beyond that. Rather, I think you should use that as a baseline for performance work as you evolve your program. Speaking of that, An Apple Library Primer has links to various WWDC talks where the linker team discusses various topics. Most notably, the 2022 talk discusses launch times. It’s well worth a watch. Finally, just for context, the libSystem initialiser does a bunch of really critical stuff. For example, it has the code that sets up the App Sandbox, if the executable enables it. If you want to see this initialiser in action, open your true clone project, set a symbolic breakpoint on libSystem_initializer, and run it from Xcode. When you stop at the breakpoint, Xcode will show a page of disassembled code, but that’s not too hard to understand. And most of the symbols are present, so you can look up the source code in Darwin. IMPORTANT The Darwin open source isn’t guaranteed to match the source used to build the OS, but it’s usually close enough to be

Reply to Entitlement not found
Xcode is telling you that com.apple.developer.shazamkit isn’t a real entitlement. See Determining if an entitlement is real for more background on this. The solution is to do what Xcode suggested, that is, remove that property from your .entitlements file.

Entitlement not found
Dears, this is my first ever piece of code on Mac. I wanted to try ShazamKit. I created App Id and enabled App Service ShazamKit. I properly configured my app (a very small test app) with the proper boundle id, Team and entitlements file. I keep receiving this error in the Signing in section: Automatic signing failed Xcode failed to provision this target. Please address the following issues preventing automatic signing from creating a valid profile. Entitlement com.apple.developer.shazamkit not found and could not be included in profile. This likely is not a valid entitlement and should be removed from your entitlements file I noticed the message is mentioning profile...does it refer to a Profile as in Certificate/Identifiers/Devices/Profiles/Keys/Services option? I did not create any Profile. I just enabled the App Service under Certificates, Identifiers & Profiles=>Identifiers=>Edit your App ID Configuration=>App Services Thx!

Notification Identifier not showing on my profile
Im creating a basic app, needs push notification capability. I have created two profiles (development & distribution), selected my app in Identifiers and checked the PN box to enable it (no need for broadcast).
