This month we will have a presentation about using NSUserDefaults in Swift by Gavin Wiggins. The NSUserDefaults class provides a simple mechanism to store application or user data in Mac and iOS apps. The most common use of this class is for storing user preferences that will persist between app launches or when the device is shutdown. We will also give away another Big Nerd Ranch book at the end of the meeting. Don't forget to join us on Twitter and GitHub for the latest news and projects and consider joining the international CocoaHeads team by submitting a Slack invitation.
