How to for loop in userDefaults swift

To get all keys and corresponding values in UserDefaults, you can use:

for (key, value) in UserDefaults.standard.dictionaryRepresentation() {
            print("\(key) = \(value) \n")
}

In swift 3, you can store and retrieve using:

UserDefaults.standard.setValue(token, forKey: "user_auth_token")
print("\(UserDefaults.standard.value(forKey: "user_auth_token")!)")
