The following error occurred when I uploaded the application for distribution in the test flight. After rebuilding, the problem resolved. What was the cause? I recently upgraded the Xcode version from 15.2 to 16.0, and this was my first build, so is it an environmental factor?
ITMS-90433: Invalid Swift Support - The file libswifCore.dylib doesn’t have the correct code signature. Make sure you’re using the correct signature, rebuild your app using the current public (GM) version of Xcode, and resubmit it. Don’t just modify the code signature of libswiftCore.dylib.
Thank you for your post. This is an interesting issue. I believe it may be an old bug. Please upgrade Xcode to the latest version available on the App Store and resubmit the App.
In the event that this issue occurs again in the latest version of Xcode and should not, please submit a code level request to us.
Only if it reproduces after upgrading to the latest version of Xcode. I’d like you to submit a code-level support request so we can discuss this further privately. When you create the request, indicate that you were referred by someone at Apple and make sure to include a link to this thread.
