An empty identity is not valid when signing a binary for the product type 'Application'. (in target 'AppRTCMobile')

my code sign setting is:

everything looks ok.

Answer 1

I added CODE_SIGNING_ALLOWED=NO as an additional parameter and that fixed this issue for me.

Answer 2

I needed to to turn OFF Automatic manage signing and turn it ON afterwards. It seems like Xcode did fix some inconsistency by that action.

Answer 3

I saw this error in Xcode 12.2b when building to run on a device, but I had not set signing to Automatic, or selected profiles, etc.

Basically I was running and testing on the simulator, then plugged in a device for testing and forgot to change any signing settings.

Perhaps this error is new to Xcode 12.x for that scenario.
