title: How to manually add a package to Swift without Cocoapods
body: <p>I'm trying to manually add JTAppleCalendar to my Swift project, but when I go to import JTAppleCalendar, or try to create a new Cocoa touch class of class JTAppleCell, it doesn't show up. I copied in the sources folder into my project as shown below.<a href="https://i.stack.imgur.com/jwwxC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jwwxC.png" alt="enter image description here"></a></p>
  
  <p>Is there a step I'm missing so that the project will read the JTAppleCalendar files?</p>
