CoreMotion data such as pressure and pedometer with 1.6 beta and ctypes?

[DrNo152]

There is probably a way to read out the pressure sensor and the pedometer of the iPhone 6 using 1.6 beta's ctypes module. However, I understand too little of the API to get this from CMAltitudeData and CMPedometerData. Sample code for learning how such (or similar) tasks could be accomplished would be much appreciated.
