I have an app I am testing on iOS 10 Beta 3 currently, and for some odd reason whenever I execute this one method, it seems to be crashing on the startPedometerUpdatesFromDate line below:
if (!_pedometer) {
_pedometer = [[CMPedometer alloc] init];
}
[_pedometer startPedometerUpdatesFromDate:[NSDate date] withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {
I have confirmed that _pedometer is not nil and it is even more odd as it worked in iOS 9 before I upgraded.
There is nothing in the console that suggests anything wrong with the code, and when it crashes it just leads to this (even with exception breakpoints):
libsystem_kernel.dylib`__abort_with_payload:

I also made sure to include Privacy - Health Update Usage Description and Privacy - Health Share Usage Description in my Info.plist. It is also being tested on an iPhone 6 Plus so I am not quite sure what the issue could be. Is there anything I am missing?
Apple Engineering has gave me the following feedback after filing a bug report:
This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSMotionUsageDescription key with a string value explaining to the user how the app uses this data.
