MotionKit

Now you can grab the data from Accelerometer, Magnetometer, Gyroscope and Device Motion in a magical way, with just a Two or a few lines of code. Fully compatible with both Swift and Objective-C.

A nice and clean wrapper around the CoreMotion Framework written entirely in Swift. The Core Motion framework lets your application receive motion data from device hardware and process that data. The data can be retrieved from Accelerometer, Gyroscope and Magnetometer. You can also get the refined and processed gyroscope and accelerometer data from the deviceMotion datatype itself instead of getting the raw values.
