Hi!

iOS 15 breaks the current code signing service. None of my signed apps work any longer.
Always says " the devoloper must update the app"

Discovered the Altstore reddit:

Maybe there is a fix for this fantastic workflow?!?

Thanks

Hey there. Signing apps for iOS 15 requires macos 11.4 or above. Currently, github actions only supports macos 10. When their 11.4 image is up, signing will work:

Alternatively you can host your own builder on your own macos 11.4:

Good news, macos 11 with iOS 15 signing is finally released to the general public:

Simply update your ios-signer-ci and signing for iOS 15 will magically work.
