Build on device fails with exit code 1

lock add unlock keychain solve the problem, it' weird.


Try updating Certificates from Preference -> Accounts -> Choose developer account and Proper Team -> View Details -> Download all profiles.

Also, try doing Deep clean using Cmd+Shift+Alt+K. Make sure you have selected correct developer team in your general settings.

Also, Change Provisioning to Automatic. So that it will automatically fetch proper certificates.

After that, Goto Build Phases ->Link Binary frameworks-> Add Frameworks you want. Do this for all targets that you have.

Try this and let me know if error still occurs.

Hope it helps..


I just simply restarted my MacBook Pro. I found this solution here.
