title: Xcode Crashes when working on UITableViewController
body: <p>Why does my Xcode hangs and start using up <strong>Mac's RAM</strong> which I later have to Force Close from my <strong>Activity Monitor</strong> whenever I try to use that aspect of <code>UITableView</code> or <code>UITableViewController</code> properties unless I restart my Mac. And once I restart and change from for instance <code>Dynamic properties</code> to <code>Static Cells</code> I can’t change back. It’ll be crashing all the way unless I restart the Mac again</p>
