There seems to be a problem to a specific Apple Developer Account regarding Xcode Cloud Distribution (Signing). The Xcode Cloud Error Invalid Signature. Code failed to satisfy specified code requirement(s). The file at path “XcodeCloudTest.app/XcodeCloudTest” is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose “Clean All” in Xcode, delete the “build” directory in the Finder, and rebuild your release target.

Investigation Apple Developer Forums This issue seems to be known: https://developer.apple.com/forums/thread/746210 Debugging by ourselves We setup an example Xcode project from a default iOS Xcode app template to rule out any project issues. This example project failed with the same error as stated above. In the next step we tried the same example project with a different Apple Developer Account and it successfully distributed the example App through Xcode Cloud. Conclusion It seems like there is no setup issue on developer-side, because our example project works out-of-the-box on a different Apple Developer Account. Our only hope is that Apple will have a look on our Developer Account. Maybe there is some internal setting.
