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

Try setting "Defines Module = YES" in your app target. Works for my project.

Answer 2

I tried all the answers above/below. None worked.

However, Restarting Xcode did it.

Try that before going into the madness of trying to fix the actual situation of the missing file. All the rest is madness. Heck, If that doesn't fix it. I would even try restarting every time you do one of the strategies listed here. Maybe one of those fix it but Xcode gets stuck until you restart it.

Nothing else to do, Xcode is just too buggy at times.

Answer 3

I had this problem because I deleted some old archives and files from my mac to make more space. However running pod install for this project solved it.

Answer 4

Perhaps your path to .yaml file contains ' character. It makes the parser confused. Using TextWrangler, you can see your path has different colors (red & black).

That's my case, and moving project to another path (which doesn't contain ') solved my problem.

Answer 5

Can fix with one shell command:

echo "{\n\t'version': 0,\n\t'case-sensitive': 'false',\n\t'roots': []\n}" > /[Long-path-goes-here]/all-product-headers.yaml

Where the path is copied out of the Xcode error.

Answer 6

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