Declare array of classes that conform to a protocol

Question

Lets say I have created this protocol and a couple of classes

import UIKit

protocol ControllerConstructorProtocol {
    class func construct() -> UIViewC         


        

Answer 1

Try this:

var myConst = MyConstructor()
var myOthConst = MyOtherConstructor()

var array:[AnyObject] = [
    myConst,
    myOthConst
]

for a in array
{
    if a is MyConstructor
    {
        println("a is type of MyConstructor")
        (a as! MyConstructor).myMethod()
    }
    else if a is MyOtherConstructor
    {
        println("a is type of MyOtherConstructor")
        (a as! MyOtherConstructor).myMethod()
    }
}

Another solution, although not that pretty...
