Is there a Swift version of NSMapTable like for NSArray (Array), NSDictionary (Dictionary) and NSSet (Set)?

AFAIK, none exists. If that's the case, is it possible to write an implementation of NSMapTable in pure Swift?

PS: This question is for two reasons. Firstly, I'd like to have a generic version of NSMapTable. Secondly, I'm curious to know if Swift has the tools needed for implementing a collection that stores weak values and removes them automatically when the values become nil.

You can wrap NSTable with your custom class. That way you wouldn't need to invent wheel – mustafa Mar 05 '15 at 13:59
@mustafa That's true, though I don't think you can store `Enum`s or `Structs` that way. – Alex Mar 05 '15 at 14:01
