I am developing a SDK which uses
SecAccessControlCreateFlags to mange key pairs generated and stored in Secure Enclave. The private key is protected by biometric and I'm using
[.privateKeyUsage, .biometryCurrentSet] configuration when generating the key pair. Everything works perfectly in my demo app.
But when my partners integrate the SDK into their apps, the app crash with the exception as in the screenshot below.
The strange thing is, the SDK is not initialised and no API from the SDK is being called at this moment. The app crashes just by linking the SDK into the app. If I comment out any line of code
[.privateKeyUsage, .biometryCurrentSet], the integration works again and the app doesn't crash.
I'm aware that the partner's apps also have similar functionality to manage their own key pairs, but from my understanding, it should not conflict with our own logic, since the key pairs are generated with different labels.
I'm completely lost now and have no idea how to fix this crash. Google doesn't help either.
Anyone has experienced the same issue and know what is going on here?
