title: What's a reliable way to make an iOS app crash?
body: <p>I want to test my app's crash reporting out in the field by deliberately having it crash when the user performs a particular action that a real user is unlikely to do accidentally.</p>
  
  <p>But what's a good reliable way of making the app crash that doesn't create a warning at compile time?</p>
  
  <p><strong>Edit:</strong> Note that many seemingly obvious answers to this question result in exceptions that get caught by Cocoa and thus don't result in the app crashing.</p>
