I just want to verify this to ensure I'm not making a dumb mistake.
Does Apple offer any of its CocoaTouch classes for Open Source? I checked opensource.apple.com, and did not see any. http://www.google.com/#q=nsuuid+site:opensource.apple.com.
I'm interested in the NSUUID class for iOS 5 and lesser (its available in iOS 6) and would be happy to copy/paste it rather than roll it myself.
No this will not be open source.
But you don't need to roll your own as you can just drop down to using CFUUIDRef
