[swift-users] Difference between Apple and Linux versions of Swift - CompareOptions

[Tony Parker]

Feel free to file issues for us at bugs.swift.org <http://bugs.swift.org/> when you find these kinds of things. Since we have two different source code bases for these APIs, we need to find and fix these kinds of mismatches. This year has had a lot of renaming, so hopefully once we get them all done we should be good to go in the future.

I am more concerned about which API will be the correct one when Swift 3 is officially released.  My assumption is the Xcode version will be the final one but just wanted to verify it.
