I found online that some guys have met the same problem before and then turned off the bitcode in the Xcode build settings to fix this. I did the same thing , nothing worked for me. Does anybody have succeeded in fixing this? Any idea would be appreciated!

Answer 1

Xcode -> preference -> locations -> Derived Data

You should remove this folder.

Answer 2

Restart the Xcode. Select Xcode -> Product -> Clean. Hope this may solve your issue. This worked for me.
