NSSet is not correctly converted

[AlexanderJ]

If I convert code with NSSet, it is not correctly translated to Swift Set. See example:
https://swiftify.me/uphuxa

I would expect something more in line with:

 func test() -> Bool {
        var test = Set<String>()
        test.insert("test")
        return test.contains("test")
 }

@AlexanderJ Acknowledged.
Precise translation of NSSet methods hasn't been covered yet, according to https://swiftify.atlassian.net/browse/SWC-128.
We will line this up.
