Swift- 4 Xcode 9.1

try this code

you can not store mapper in NSUserDefault, you can only store NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.

let myData = NSKeyedArchiver.archivedData(withRootObject: myJson)
UserDefaults.standard.set(myData, forKey: "userJson")

let recovedUserJsonData = UserDefaults.standard.object(forKey: "userJson")
let recovedUserJson = NSKeyedUnarchiver.unarchiveObject(with: recovedUserJsonData)
