error: unable to load standard library for target 'arm64-apple-ios10.0-simulator'?

Question

I updated my Xcode but not able to build. It\'s failing with:

:0: error: unable to load standard library for target \'arm64-appl

Answer 1

I just had this issue occur randomly. There were no build errors in my code. After swicthing to new simulator & cleaning build folder with no luck, I restarted xCode (11.5), and the issue self-resolved. Anytime you get wierd build failures, restart xCode.
