I want to upload my app to appstore, after getting success build I am trying to archiving my project but getting following error,
clang: error: clang frontend command failed with exit code 70 (use -v to see invocation)
What went wrong? Can someone help me to fix this?
Remove old references by cleaning the derived data of your app. Quit/Open Xcode & then try to archive.
PS: Update your XCode & Swift
