Malformed or corrupted AST file

I have a problem I don't know why did it happen in the first place but most probably because I've pressed move to trash to some system frameworks by mistake.

I got an error that says:

malformed or corrupted AST file: 'could not find file '/Users/username/myProject/QuartzCore.framework/Headers/CAMediaTiming.h' referenced by AST file'

I've tried to copy QuartzCore.framework in that Directory. It give me then a punch of new errors. Then if I remove the framework from the Dir. Everything will be good for the project till I make any code change. Then I would have to make the previous scenario again. It's very annoying now and I really need to fix this. Anyone?

Solution

  • As requested:

    What caused this error for me (after getting the new Xcode) was I would try to run a project in simulator (accidentally in simulator, I never use simulator), but I'd forget to select my device or my device would become unplugged without me noticing, and it will try to run in simulator... so I would get those classic ".o" file errors... Then I would switch back to my device and get corrupt AST files...

    To CURE the problem... (Follow the steps below VERY closely!!!!!)

    1. Clean your project
    2. QUIT Xcode (CMD+Q)
    3. Run this Terminal Command:
      rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache/*
    4. Run this Terminal Command:
      rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/*
    5. Reopen Xcode
    6. MAKE SURE YOU HAVE YOUR DEVICE SELECTED AND NOT SIMULATOR
    7. CLEAN project (Yes, again)
    8. THEN build (to your device, not to simulator)...

    Enjoy!

    Note: After further experimentation I've found that the force-quitting of xCode is possibly not necessary.
