How to Make an iOS PDF Editor with Swift Package Manager

It's easy to embed ComPDF into an iOS application with a few lines of Swift or Objective-C code. Take a few minutes to get started.

The following sections explain how to run integration with Swift Package into your project

Creating a New Xcode Project

1. Open Xcode and select File > New > Project… to create a new project for your application:

   

2. Choose the App template for your project:

   

3. When prompted, enter your app name (ComPDFKit-Demo) and your organization identifier (com.example) and choose Storyboard for the interface:

   

4. Click Next and select the location to save the project.

5. Click Create to finish.

Integrate ComPDFKit Apple Package into SPM

1. Open your application in Xcode and select your project’s Package Dependencies tab.

   

2. Copy the ComPDFKit Apple package repository URL into the search field:

   https://github.com/ComPDFKit/compdfkit-pdf-sdk-apple-package

   

3. In the Dependency Rule fields, select Branch > master, and then click Add Package.

4. After the package download completes, select Add Package.

5. ComPDFKit should now be listed under Swift Package Dependencies in the Xcode Project navigator.

Display a PDF Document

So far, we have added "ComPDFKit.xcframework" to the "PDFViewer" project, and finished the initialization of the ComPDFKit PDF SDK. Now, let’s start building a simple PDF viewer with just a few lines of code.

1. Prepare a test PDF file, drag and drop it into the newly created PDFView project. By this way, you can load and preview the local PDF document using NSBundle. The following image shows an example of importing a PDF document named Online5 into the project.

   

2. Create a CPDFDocument object through NSURL, and create a CPDFView to display it. The following code shows how to load PDF data using a local PDF path and display it by CPDFView.

   guard let filePath = Bundle.main.path(forResource: "Online5", ofType: "pdf") else { return  }
   let url = URL(fileURLWithPath: filePath)
   let document = CPDFDocument(url: url)
   
   let rect = self.view.bounds
   let pdfView = CPDFView(frame: self.view.bounds)
   pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
   pdfView.document = document

3. Add the created CPDFView to the view of the current controller. The sample code shows below.

   self.view.addSubview(pdfView)

   The code shown here is a collection of the steps mentioned above:

   override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
           
        guard let filePath = Bundle.main.path(forResource: "Online5", ofType: "pdf") else { return  }
        let url = URL(fileURLWithPath: filePath)
        let document = CPDFDocument(url: url)
   
        let rect = self.view.bounds
        let pdfView = CPDFView(frame: self.view.bounds)
        pdfView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        pdfView.document = document
        self.view.addSubview(pdfView)
   }

4. Connect your device or simulator, and use shortcut Command_R to run the App. The PDF file will be opened and displayed.
