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 force the downcast (as!) as below

func getGeneric() -> T.Type {
  return Int.self as! T.Type
} 

But out of the function scope, you need to indicate the returned type:

var t:Int.Type = getGeneric()
