Dynamic Class Types In Swift

Here is a pure swift implementation of dynamic class types. It does require the classes to extend the same protocol.

protocol ILayout{ init(_ a: String)}
class A: ILayout{ required init(_ a: String) }
class B: ILayout{ required init(_ a: String) }
var instance:ILayout
var classType:ILayout.Type

classType = A.self
instance = classType.init("abc")

classType = B.self
instance = classType.init("abc")
