Xamarin.IOS: UITableViewSource crashes on device
<p>I've a very simple app which contains only <strong>UITableView</strong> and its <strong>UITableViewSource</strong>..</p>

<p>When using UITableView without linking to UITableViewSource (the app <strong>works in simulator &amp; device</strong>)</p>

<p>But when I link the UITableView to the UITableViewSource (the app <strong>works in simulator</strong> but <strong>crashes on device</strong>)</p>

<p>( The device is <strong>iPad</strong> running IOS 9.2.1 )</p>

<p>it gives me this long error:</p>
