Here's a Swift translation for Ferran Maylinch's answer above.

Had a similar problem in a Swift project after I duplicated the original target in order to have 2 builds of my product. The 2 builds needed to be useable interchangeably.

So, I had something like myapp_light.app and my app_pro.app. Setting the class fixed this issue.

NSKeyedUnarchiver.setClass(MyClass1.classForKeyedUnarchiver(), forClassName: "myapp_light.MyClass1")
NSKeyedUnarchiver.setClass(MyClass1.classForKeyedUnarchiver(), forClassName: "myapp_pro.MyClass1")



if let object:AnyObject = NSKeyedUnarchiver.unarchiveObjectWithFile("\path\...") {
    var myobject = object as! Dictionary
    //-- other stuff here
}
