// Get the file manager
let fileManager = NSFileManager.defaultManager()

// For other options usable in iOS besides .DocumentsDirectory see:
// http://stackoverflow.com/questions/7268299/path-directory-usable-in-ios
let directoryURLs = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask) as [NSURL]
// Cast to [NSURL] because it 'helpfully' gives back [AnyObject]

// iOS should only give you a single documents directory for your app
