Apple LLVM 6.0 Error

Question

I recently downloaded and installed the XCode6-Beta and I am getting this build error. Steps already taken:

1. Double checked my prefix header file.
2. Cleaned project.
3. Restarted XCode.
4. Deleted DerivedData like 100 times!

Any thing I may be missing?

Command /Applications/Xcode6-Beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

EDIT: Temporary Solution.

I removed the 6.0 support which was one of the areas causing problem however, if you need support for earlier versions this will still be an issue.

Answer 1

Ther is one way!

Select Targets/Build Settings/ Scroll to Apple LLVM 6.0 - Preprocessing

-> ENABLE FOUNDATION ASSERTIONS set it to NO
