iOS - Swift Reference

This is a playground that I made based on the Apple Swift documentation and then I added some samples of general code like Notifications, JSON Serialization and REST Requests. This project requires XCode 7.

Feel free to take a look and if you want to add something, pull requests are welcome :)
