Class casting dynamically in swift

Question

I am trying to dyanmically cast to a class in Swift. Is this possible? Here is the code I am trying to use:

let stringClass: AnyClass = NSString.self
let anyObje

I'm not seeing what the cast at this point is for. You can write:

let controllersDictionary: [String: String] = [
    "valueOne" : "bar",
    "valueTwo" : "foo"
]
let identifier = controllersDictionary[value]!
let viewController = storyboard.instantiateViewController(withIdentifier: identifier)

The cast does nothing for you in the code that you have shown. viewController is typed as UIViewController, but it is the correct underlying view controller subclass thanks to polymorphism; whatever the class is in the storyboard, that's the class of this instance.

The only time you need to cast down is when you have to message an instance with a message belonging only to the subclass, and you have not shown any such need at this point in your code.
