Say I were using this code to save an image to the documents directroy
let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory
let nsUserDomainMask
Swift 2
If you want to get a file from your document directory in Swift 2:
let path: String? = NSBundle.mainBundle().pathForResource("imageName", ofType: "png", inDirectory: "DirectoryName/Images")
let imageFromPath = UIImage(contentsOfFile: path!)!
self.myImage.image = imageFromPath
Hope that helps somebody
