How to use the enumerateObjectsWithBlock method on NSArray with Swift

enumerateObjectsWithBlock Swift

let nArray : NSArray = ["1", "2", "3"]
nArray.enumerateObjectsUsingBlock {(obj, index, stop) in
    println("Object \(obj) Index \(index)")
    if index == 1 {
        stop.withUnsafePointer { $0.memory = true }
    }
}

If you want the same behaviour in a more Swift-y way:

let array: NSArray = ["1", "2", "3"]

for (index, obj : AnyObject) in enumerate(array) {
println("Object (obj) Index (index)")
if(index == 1){
break;
}
}

I don't think need to explicitly declare a return type of void: '-> void'.

Otherwise, this is cool!

Updated to remove unneeded syntax.

Just a note, this was never intended to be the way do enumerate over an array, just a academic exercise to try and use some C pointers in swift
