Where is CountedSet in Swift 3 (beta 6)?

Swift 3 introduces the CountedSet class (yes it's a class, not a struct) which should replace/bridge the old Objective-C NSCountedSet class.

Solution

  • Based on this proposal, CountedSet has been considered and rejected or deferred.

    The following classes were considered and rejected or deferred for the described reasons:

    OrderedSet, CountedSet: We will consider these types in a future proposal.
