Hello,
I have a strange problem.
After upgrading an App, on some devices, it crashes at boot and the log says: EXC_BAD_ACCESS (SIGKILL - CODESIGNING).
The certificates are ok, and the same binary works on other devices with the same iOS version.
I converted the App to xcode 7, autogenerate new certificate and the App works again.
In xcode 7 with the old certificate the App crashes.
All the certificates are valid.
This happens only with some devices (2 of 40).
Thanks.
Santino
