Swift: Use NSUserDefaults to Store Persistence Data
From Hawk Wiki
//Set data
NSUserDefaults.standardUserDefaults().setObject(["settingABC": false], forKey: "settingABC")
//Load Data
//func objectForKey(defaultName: String) -> AnyObject?
let settings = NSUserDefaults.standardUserDefaults().objectForKey("settingABC") as? [String: Bool]
To sync/update NSUserDefaults
NSUserDefaults.standardUserDefaults().synchronize()
