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

You can return any type you want.

func getTypeOfInt()  -> Int.Type  { return Int.self  }
func getTypeOfBool() -> Bool.Type { return Bool.self }

If the type is not determined from arguments or if the return is constant, there is no need to introduce a generic T type.
