Is there any way of testing altitude code prior to having my hands on an iPhone 6?
[CMAltimeter isRelativeAltitudeAvailable] returns FALSE when run in Simulator with iPhone6.
Similar to all of the other Core Motion (CM) classes, CMAltimeter does not work in the simulator and requires an iPhone 6 or 6+. Though some people have rigged accelerometer and gyroscope simulators that can augment the simulator, it took a long time for this to be created and there is no such equivalent for CMAltimeter.
