Xcode 6 beta 3: invalid virtual filesystem overlay file

Question

After updating to Xcode 6 beta 3 the compiler keeps crashing with the following error:

/[Long-path-goes-here]/all-product-headers.yaml:4:13: error: Could not         


        

Answer 1

Clean (command-shift-K), and clean-build-folder (command-alt-shift-K) and build again worked for me.
