Create WebViewer App in Xcode

WebViewer is a powerful JavaScript-based PDF viewing and document editing library developed by PDFTron Systems Inc. It allows developers to integrate a comprehensive set of PDF functionalities into web applications, making it possible to view, annotate, fill forms, and manipulate PDF documents directly within a web browser.

With WebViewer, developers can build custom PDF solutions tailored to their specific needs. It provides a flexible API that enables deep customization and integration with other web technologies. WebViewer is compatible with various platforms and browsers, including desktop and mobile devices, making it accessible to a wide user base.

WebViewer is widely used by organizations in industries such as finance, legal, healthcare, and education, where PDF documents are a common format for sharing and processing information. It provides a reliable and secure solution for handling PDF files within web applications, empowering users with powerful document management capabilities.

To create a WebView app in Xcode, you can follow the steps below:

Step 1: Open Xcode and create a new project.

  • Launch Xcode and select “Create a new Xcode project.”
  • Choose “App” under the “iOS” section.
  • Select the “Single View App” template and click “Next.”

Step 2: Configure the project settings.

  • Provide a product name for your app, such as “WebViewApp.”
  • Choose the desired organization identifier and set the language to Swift.
  • Select the location to save your project and click “Create.”

Step 3: Design the user interface.

  • Open the Main.storyboard file in the project navigator.
  • Delete the existing view controller scene by selecting it and pressing the Delete key.
  • Drag and drop a new “View Controller” from the Object Library onto the canvas.
  • Select the newly added view controller and go to Editor -> Embed In -> Navigation Controller.

Step 4: Add a WebView to the view controller.

  • Drag and drop a “Web View” from the Object Library onto the canvas.
  • Resize and position the web view to fit the view controller’s bounds.
  • Connect the web view to an outlet in the view controller by selecting the web view, opening the Assistant Editor, and creating an outlet using the “+” button in the view controller’s code.

Step 5: Implement WebView functionality.

  • Open the ViewController.swift file.
  • Import the WebKit framework by adding import WebKit at the top of the file.
  • Create a property for the web view in the view controller class:
@IBOutlet weak var webView: WKWebView!
  • In the viewDidLoad() method, load a web page in the web view:
override func viewDidLoad() {
    super.viewDidLoad()
    
    let url = URL(string: "https://www.example.com")!
    let request = URLRequest(url: url)
    webView.load(request)
}

Step 6: Build and run the app.

  • Connect your iOS device or choose a simulator from the Xcode toolbar.
  • Click the “Build and Run” button (or press Command + R) to build and run the app.
  • Xcode will deploy the app to the selected device or simulator, and you should see your web page loaded in the app’s WebView.

That’s it! You have created a basic WebView app in Xcode using Swift. Feel free to customize the app further, add navigation controls, handle user interactions, or integrate additional features as needed.
