Can't get rid of Apple LLVM 5.0 Error

Question

It keeps saying:

fatal error: file '/Applications/Xcode5-DP5.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/include/objc/NSObject.h'

has been modified since the precompiled header

'/Users/jackiexu/Library/Developer/Xcode/DerivedData/ModuleCache/2MWVPCGUMQ29P/ObjectiveC.pcm' was built

note: after modifying system headers, please delete the module cache at '/Users/jackiexu/Library/Developer/Xcode/DerivedData/ModuleCache/2MWVPCGUMQ29P'

1 error generated.

I must have deleted the derived data at least five times by now, and I'm getting nowhere. Any ideas?

Solution 1

Open a terminal and type in : rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache/*

Clean your project and build again. Worked for me.

Solution 2

Delete the folder, clean the app, restart Xcode if necessary.

Solution 3

as per xcode 5.

1. click on Xcode preferences
2. Goto locations tab
3. click on the derived data path which navigates to the folder called DerivedData
4. Delete the whole folder and restart xcode.

This works fine for me.

Happy coding :)

Solution 4

The same thing was occuring to me. The warning was telling me:

After modifying system headers, please delete the module cache at '/Users/yunus.mehel/Library/Developer/Xcode/DerivedData/ModuleCache/13XL2DHZVON89'

So, I have restarted xcode, deleted derived data from Organizer, deleted derived data from the derivedData folder; none of them worked. Then I have realized, the solution was already there; go to:

"DerivedData/ModuleCache/13XL6DH2BON89"

and delete that folder, not the "DerivedData/<your_project>". Make a clean build, it will work again.

Solution 5

Have you tried reinstalling xcode? And have you cleaned using cmd+shift+k ?

I did that, but with no result.

This worked for me! Don't forget to substitute "yourusername" with your actual computer's login username in the address he posted!

[Harlan Haskins]

It'd probably be better to just use ~/Library/Developer/Xcode/DerivedData/ModuleCache/* instead of substituting for yourusername

[Joshua Gross]

I had to do it in exactly this order: Clean the app, close Xcode, remove everything in ModuleCache (one level up from the directory Xcode tells you to remove), start Xcode again.

This doesn't work unless you delete ModuleCache. See the answers below.

Hey Jackie Xu, can you accept this as an answer? It seems to be working for most people.

Just cleaning the project was enough for me

OH! Finally... Thanks Bro!

[csotiriou]

Deleting ALL DerivedData (the entire folder) seemed to do the trick for me.

Thanks for the pointer to /var/folders. I was running into this with one of our frameworks, and cleaning out ...DeveloperTools/6.2/Xcode/... was what fixed it.
