I've stable code and its working fine for last version Xcode 11, I just updated OS and Xcode but now Xcode throwing error The Xcode build system has crashed. Please close and reopen your workspace. and also Command ProcessPCH failed with a nonzero exit code I googled and did following steps.
- Deintegrate pods, remove workspace delete pod.lock file and again install pods
- Delete drive data and clean and again start
- Quit Xcode and again open
- Finally restart OS
after all above steps I'm still facing same issue for Xcode 12.0.1 I don't know its Xcode issue or anything else but my code was working fine before update.
