[swift-users] Possible swift 3 method rewrite issue with NSRequestConcreteImplementation ?

We renamed some of these methods for Swift 3 in an attempt to remove some of the confusion surrounding which of these did what - they were really named for C types and not Swift ones.

encodeInt:forKey: and decodeInt:forKey: are the two missing ones, since they were easily confused with the Swift Int type. I think we’ll have to figure out a different approach here. John, please file a bug at bugreport.apple.com and let me know the radar number, and we’ll look into it.
