UUID is not just [A-F0-9]{24}

xUnique Webkit2 project file:

https://github.com/truebit/webkit/raw/master/Source/WebKit2/WebKit2.xcodeproj/project.pbxproj

Error below:

Uniquify and Sort
Uniquify done
Traceback (most recent call last):
  File "./xUnique.py", line 485, in <module>

    lines.sort(key=lambda file_str: pbx_key_ptn.search(file_str).group(1))
AttributeError: 'NoneType' object has no attribute 'group'

Cause:
Keys contains characters other than A-F:

               1QQ417CB12C00CCA002BE67B /* TextCheckerCompletion.h in Headers */ = {isa = PBXBuildFile; fileRef = C1684239EEDFF3D67034DD5F02609AB2 /* TextCheckerCompletion.h */; };

Fix:
Use [A-Z0-9]{24} for UUID
