xcode 8.1 xib editing hang, text editor workaround?
<p>So, since updating, the gui randomly hangs editing a xib file. The scenario goes like this:</p>

<p><a href="https://i.stack.imgur.com/nMY1R.png" rel="nofollow"><img src="https://i.stack.imgur.com/nMY1R.png" alt="enter image description here"></a></p>

<ol>
<li>click an object - i.e, array controller</li>
<li>expand a parameter, Filter Predicate here</li>
<li>Select target object in pull down</li>
<li>try to enter model key path - HANG</li>
</ol>

<p>In different xib files, the hang comes when trying to enter the model key path textfield.  I've also seen errors citing bogus fields like 'Hidden3' for some attribute bindings - only workaround was to remove them.</p>

<p>Has anyone ventured to editing the xml directly, but I guess I can do that in code :-(</p>
