Application is failing on iPad Air 2 running iOS 9.2.1 and works on all other devices
<p>I have been struggling to figure out the problem I am have with my application. I have submitted it to apple and it has been rejected with the saying "2.10 Details
Your app crashed when reviewed on iPad running iOS 9.2.1 when we:
- Launch on launch". The app works on my iPad 3rd generation, all the simulators, and my iPhone 6. When I asked what device it was crashing on, they said it was the iPad Air 2. Unfortunately, I don't own an iPad Air 2 and have no other way to get the same results. Here are the things I have tried to solve the problem:</p>

<ul>
<li><p>I deleted the "Supported interface orientations (iPad)" from my .plist - nothing changed</p></li>
<li><p>I created a new scheme that tested the app in release mode in the simulator - no errors</p></li>
<li><p>I tried symbolicating the crash report but I have yet to produce anything from that..it's possible I could be doing it wrong.</p></li>
</ul>

<p>I have posted the crash report below and the error seems to be EXC_BREAKPOINT (SIGTRAP). To my understanding this is an error that relates to a non-optional type with a nil value or a failed force type conversion. If that is the case, why would other devices not experience the same error when they launch? Does the iPad Air 2 do something different at launch that I am not aware of. My only guess at this point is that it has something to do with my build settings. I only included the first few binary images because I don't have space in this post.</p>
