Xcode 6 Swift - Displaying a local PDF

I wanted to be able to display a local PDF in my app but couldn't find an effective method to do so. I have already tried creating a Webview and downloading the PDF each time the app runs, but I would like for the app to display a local version. I found multiple tutorials on YouTube, however, they were all in Objective-C. Here are the links (in objective-c) of something similar to what I'm trying to do:

I'm new to programming in general, so it would be great if your steps would be as detailed as possible. Thanks in advance.
