fatal error: malformed or corrupted AST file - Xcode

Question

I get this error when building my app in the latest version of Xcode:

Answer 1

If you have your project scheme set to "Wait for executable to be launched" this error might happen.

In that case, just changed your scheme from Product > Scheme > Edit Scheme...
