If you look in viewDidLoad, the first method called is setup, which calls the following three functions.

The project uses a sample PDF from Apple called "iOS Deployment Overview for Business". We'll start by adding basic support for loading and displaying PDF content. nextButton - Button used to navigate to the next page.previousButton - Button used to navigate to the previous page.We will use this to show and hide the sidebar.
sidebarLeadingConstraint - The NSLayoutConstraint that binds the sidebar to the main view's leading edge.It supports vertical and horizontal layouts and allows users to navigate the document by selecting or panning the thumbnails. pdfThumbnailView - PDFThumbnailView automatically generates a set of thumbnails for the PDF's pages.The PDFView also maintains page history, so users can jump around in the document and you can support navigating that history.
By default, users can select and copy text and pinch to zoom.
pdfView - PDFView is the main class from PDFKit for displaying PDF content. Well start with PDFKit basics and will create first Ink annotations in the end of this tutorial. The storyboard has five outlets which you can see in the "Outlets" section at the top of ViewController.swift. The structure is relatively simple, just a single view controller embedded in a navigation controller. The starter project has all of the storyboard setup and the general outline of our project. To get started, download the starter project here. In this tutorial we'll see how easy it is to view PDFs, add page thumbnails, and navigate the document using PDFKit. Previously, viewing PDF files meant rendering each page yourself with Core Graphics and Core Text, using an indirect solution like UIWebView or QuickLook, or allowing the user to choose a third-party app that supports PDF viewing with a UIDocumentInteractionController. PDFKit has been available to Mac developers since 10.4, but with iOS 11 Apple brought its support for viewing, editing, and authoring PDFs to iPhone and iPad.
