GoodPersistence

A property wrapper, designed to simplify the process of caching data into the keychain and UserDefaults storage. This wrapper makes it possible to quickly and easily implement caching mechanisms in the applications, without having to write extensive amounts of code. The property wrapper takes care of all the underlying complexity, allowing developers to focus on their application's functionality.
