![]() I will not be including the PDF file in the repo as I am not sure what license it has and if I am allowed to distribute it.īecause we are adding this PDF to our project we can use Bundle.main to get the file's URL. PDFKit is a PDF document generation library for Node and the browser that makes creating complex, multi-page, printabledocuments easy. In the last step, iOS will do all the hard work for you. However, using it takes a little extra work because it doesn’t read PDF directly you first load the PDF into a PDFView, then connect that to the thumbnail view. By relying on Apple’s numerous frameworks, you can write apps that do a lot while writing as little Swift code as possible. Use of those HTML templates to produce the real content (optionally display it in a web view). Apple’s PDFKit framework provides a huge range of code to help us work with PDFs, including a dedicated view for rendering thumbnails of PDF pages: PDFThumbnailView. I have named this file heaps.pdf, so in the code below you will see that I use the file name heaps. Creation of HTML templates for the forms or the content needed to be printed to PDF. We'll take you through the latest features in PDFKit, including support for live text and forms, creating PDFs from images, building interactive overlays, and saving annotations. To do that I have used the following PDF file -. PLHKit: A Swift DSL for Rendering and creating PDF Files. Discover PDFKit a full-featured framework that helps your app view, edit, and save PDF documents. In order to do that we need to have a PDF file that we can add to our project. Now that we know what we are doing, let's get to the code: Step 1: Get URL for local PDFĪs I mentioned earlier in this tutorial we will be focussing on how to open a local PDF file. GitHub - ketyung/SwiftUIPdf: Sample source code for tutorial - Build a PDF composer app with PDFKit - the SwiftUI and MVVM way. You can also find the full source code for this tutorial here. Both methods that we are going to use today allows for us to use a URL when trying to load the PDF, so it doesn't matter whether the URL is a local file or not.Įven though this tutorial is not focussed on opening a remote PDF, I will be adding the code at the end of each section that will allow you to open a remote PDF file. If you want to use a hosted file it will work in basically the same way. The PDF can be a local file or a hosted file but we will be using a local file. In this tutorial we explore two ways of opening a PDF file with Swift. If delta > 0.PDF files are common place and with iOS/iPadOS becoming a more powerful operating system, opening PDF files and other regular computer type tasks will become more common place. ![]() offset(x: viewState.width, y: viewState.height) Apples PDFKit framework is a relatively easy way to add basic PDF viewing and interaction capabilities to your iOS app but it is not a complete solution and requires extra work to develop the UI and annotation capabilities. Apple’s PDFKit framework provides a huge range of code to help us work with PDFs, and one of the most useful is PDFView it renders PDFs to the screen and lets users interact with them. Discover PDFKit a full-featured framework that helps your app view, edit, and save PDF documents. struct ContentView: View private var scale: CGFloat = private var lastScale: CGFloat = private var viewState = CGSize.zero Use of viewState allows a changing offset position when using the drag gesture. The code creates a pinch-to-zoom effect by adding a drag gesture in addition to the magnification gesture.
