iPhone ARKit is a small set of class that can give you augmented reality in any iPhone application. The kind of augmented reality that ARKit caters to is overlay of information (usually geographic) over a camera view. The background camera view acts as a "window" onto the world around you.

iPhone ARKit's APIs are modeled after MapKit's. For an overview of MapKit, please read the documentation for more information.

While iPhone ARKit's API isn't an exact match, one controller can act as the delegate for both and serve up all location information. Please see the documentation in our wiki (forthcoming!).

A simulated version of the iPhone's StoreKit, for testing store UIs on the iPhone Simulator, or even on device without having to set up IAP in Connect.

SwapKit is a library to allow locally installed iPhone apps to share data among themselves. It supplies facilities iPhone OS does not provide, including shared metadata on installed apps, binding applications to data types and app capabilities (similar to how apps in desktop OSes bind themselves to file types), and providing one-way and (planned) two-way communication to let apps collaborate and do more than any single one could ever hope to.

InAppSettings is an open source iPhone and iPod touch framework for displaying an in app version of the settings from the Settings.bundle.

A library for testing resolution-independent iPhone OS applications.

ResKit simulates varying device screen sizes by resizing and moving your application's main window. It supports scaling down the simulated device so more of the screen can be seen at once.
