Dragging and dropping not working in Xcode
<p>I'm working on my first Swift project in Xcode and am running into trouble with dragging and dropping elements from the storyboard into the code. </p>

<p>Nothing happens when I try dragging and dropping. I'm running the newest version of Xcode and using Swift. </p>

<p>The class is <strong>ViewController</strong> and the file is <strong>ViewController.swift</strong></p>

<p>I'm trying to drag and drop a textfield into the class. </p>
