title: CMPedometer SIGABRT crash iOS 10?
body: <p>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 <code>startPedometerUpdatesFromDate</code> line below:</p>
  
  <pre><code>if (!_pedometer) {
      _pedometer = [[CMPedometer alloc] init];
  }
  [_pedometer startPedometerUpdatesFromDate:[NSDate date] withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {
  </code></pre>
  
  <p>I have confirmed that <code>_pedometer</code> is not <code>nil</code> and it is even more odd as it worked in iOS 9 before I upgraded. </p>
  
  <p>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):</p>

  </code></pre>
  
  <p>I also made sure to include Privacy - Health Update Usage Description and Privacy - Health Share Usage Description in my <em>Info.plist</em>. 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?</p>
