Apple LLVM 6.0 Error: clang failed with exit code -1

Question

I created my app on my MacBook Air and kept working with it there which was fine. Then I started working with a colleague who used another Mac (of course). Anyway, we share our Xcode project via Dropbox (we are just switching to BitBucket, don't worry ;) ), when he tried to open the project on his Mac there was a Apple LLVM 6.0 Error with the following error while on my computer the same project runs perfectly:

clang: error: no such file or directory: '/Users/linus/Dropbox/Apps/My App/Projekt/My App/SlideMenu/SlideMenu-Prefix.pch' clang: error: no input files

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

The last lines of the error seem most important to me which is why I listed them here.

I do know this question was asked several times now but there was never a useful answer which worked for me. I tried to disable the Foundation Assertions as it said in another answer on this topic but that did not work. Also I restarted & even reinstalled Xcode and all files are existing, none should be missing.

I am running Xcode 6.0.1 and Mac OS X 10.10. I hope someone can answer this, I'm kind of desperate now...

Answer 1

Hey I just ran into the same problem. Basically I deleted my tests target. I found this:

Errors When Compiling iOS 8, Xcode 6.0.1

Which basically says that:

Click on the name of your project on the list of files/folders on the left in Xcode (at the very top of the list). Look at the "Targets" section on the left-hand side of the window to the right. Likely, there's two listed with the second being a "test" item. Right-click on that item and select "delete". Then try to run the project again. See screenshot below for a visual cue.

And a picture to help you out:

Hope this helps!

EDIT: Also in the tests target, I actually found that I didn't necessarily need to delete it, there was a broken path, just fixing it makes it all work again.

1. Make new file: ⌘cmd+N
2. iOS/Mac > Other > PCH File > YourProject-Prefix.pch.
3. Project > Build Settings > Search: "Prefix Header".
4. Under "Apple LLVM 6.0" you will get the Prefix Header key
5. Type in: "YourProjectName/YourProject-Prefix.pch"
6. Clean project: ⌘cmd+⇧shift+K
7. Build project: ⌘cmd+B
