Dictionary value by key

Question

While trying to get a value from a Dictionary, Xcode is showing me the following error:

Could not find an overload for 'subscript' that accepts the supplied arguments

class func fromDictionary(enterpriseDictionary:Dictionary<String, AnyObject>) -> Enterprise
{
    var enterprise:Enterprise = Enterprise()

    enterprise.id = enterpriseDictionary["id"] as Int  (ERROR OCCURS HERE)
    enterprise.name = enterpriseDictionary["name"] as? String ( AND HERE )


    return enterprise
}

Yeah I guess `Int` and `String` aren't objects, so `Any` is what you want. You can't downcast an object to a primitive type, the compiler can see that coming a mile away. — iluvcapra, Jun 04 '14 at 17:18

I managed to resolve this question by replacing the "AnyObject" by "Any" as seen below:

class func fromDictionary(enterpriseDictionary:Dictionary<String, Any>) -> Enterprise
{
    var enterprise:Enterprise = Enterprise()

    enterprise.id = enterpriseDictionary["id"] as Int
    enterprise.name = enterpriseDictionary["name"] as? String


    return enterprise
}

As @Andrey Tarantsov said:

This occurs because AnyObject is for any class instance (you can also think of it as objects in Objective-C sense); String and Int are not classes.

Because AnyObject is for any _class instance_ (you can also think of it as objects in Objective-C sense); String and Int are not classes. – Andrey Tarantsov Jun 04 '14 at 07:45
