Swift: how to return class type from function

Question

I know it is possible to pass class type to a function in swift:

func setGeneric(type: T.Type){ }
setGeneric(Int.self)

But how we can

Answer 1

Yes, this is possible. The problem here is that you say your function returns a generic T.type, but you always return Int.type. Since T is not always an Int, the compiler raises an error.
