Swift: Downcast AnyObject to Int
Raw
anyobject-to-int.swift
func didReceiveCredit(creditInfo: [NSObject:AnyObject]!) {
// the following does not work
var amount: Int = creditInfo["credits"]! as Int
// nor does this
var amount: Int = Int(creditInfo["credits"]! as NSNumber)
// but this does
var amount: String = creditInfo["credits"]! as String
// so we can get what we want with this
var amount: Int = (creditInfo["credits"]! as String).toInt()!
