Xcode hangs/unexpectedly quit while opening large Main.storyboard
<p>I got chance for working on a huge iOS project, for Views <code>Storyboards</code> are used in this project. There is advantage of using Storyboard that everything in a single file, but now that <code>Main.storyboard</code> is grown tremendously over the period of time, whenever I open <code>Main.storyboard</code> in <code>Xcode</code> for any updates it takes minutes, and <code>Xcode</code> gets hang or <code>Quits unexpectedly</code>.   </p>

<p>What should I do to take on this problem, is there any design to split down large <code>Storyboard</code> file?</p>
