Answer 1

Array is a Swift construct, and generic struct, which means that it can be an array of any specific type (Int, String, AnyObject, etc.)

AnyObject is an object of any class, including Objective-C classes.

NSArray is an Objective-C construct that can hold any Objective-C object and is transparently mapped to and from Array
