clang: error: clang frontend command failed with exit code 70 (use -v to see invocation)

Question

I don\'t know what causes it.

It does not happen at iPhone 5 and simulators. It have been happened only my original device iPhone 7.

fatal error: err         


        

Answer 1

I got this error when i was archiving my app with xcode - while running on sim and physical device worked -, but had my physical device still selected as a scheme. Solution worked for me: clean build folder, and select 'Generic IOS Device' as the scheme.
