It’s interesting which foundation calls are built in and which are not. (This may change with beta iteration)

// Playing with Foundation objects

import UIKit

import Foundation

 

var str = NSHomeDirectory()

str.pathComponents

 

var array : AnyObject[] = []

array += 5

array += “hello”

 

// This doesn’t work

//array.indexOfObject(5) // nope

 

// These all work

(arrayasNSArray)

(arrayasNSArray).indexOfObject(“hello”)

(arrayasNSArray).indexOfObject(5)

array.count
