How to Use SwiftSoup in Swift Playgrounds on iPad

Introduction

If you want to parse HTML in Swift Playgrounds on iPad, you can use SwiftSoup, a powerful Swift library for handling HTML.

It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jQuery-like methods. SwiftSoup implements the WHATWG HTML5 specification, and parses HTML to the same DOM as modern browsers do. Scrape and parse HTML from a URL, file, or string. Find and extract data, using DOM traversal or CSS selectors. Manipulate the HTML elements, attributes, and text. Clean user-submitted content against a safe white-list, to prevent XSS attacks Output tidy HTML SwiftSoup is designed to deal with all varieties of HTML found in the wild; from pristine and validating, to invalid tag-soup; SwiftSoup will create a sensible parse tree.
This guide will walk you through adding SwiftSoup to your project and testing it with a simple SwiftUI interface on Ipad.


Step 1: Add SwiftSoup to Swift Playgrounds

  1. Go to the SwiftSoup Repository:
    Open Safari and visit:
    SwiftSoup GitHub
  2. Copy the Repository URL:
    Click the <> Code button and select Copy URL to Clipboard.
    You should get: https://github.com/scinfu/SwiftSoup.git
  3. Add SwiftSoup in Swift Playgrounds:
    • Open Swift Playgrounds on your iPad.
    • Create a new App project.
    • Tap More (•••) > Add Package.
    • Paste the copied URL and add the package.

Step 2: Create a Swift File to Test SwiftSoup

Now that SwiftSoup is installed, let’s create a simple SwiftUI app to test it.

Create a New File: SwiftSoupTest.swift

  • Delete MyApp.swift and ContentView.swift.
  • 
    import SwiftUI
    import SwiftSoup
    
    @main
    struct SwiftSoupTestApp: App {
        var body: some Scene {
            WindowGroup {
                ContentView()
            }
        }
    }
    
    struct ContentView: View {
        @State private var extractedText: String = "No text extracted"
    
        var body: some View {
            VStack {
                Text("SwiftSoup Result:")
                    .font(.headline)
                
                Text(extractedText)
                    .padding()
                    .border(Color.gray)
                
                Button("Parse HTML") {
                    extractedText = parseHTML()
                }
                .padding()
            }
            .padding()
        }
        
        func parseHTML() -> String {
            let html = "<p>Hello <b>SwiftSoup</b></p>"
            
            do {
                let doc = try SwiftSoup.parse(html)
                return try doc.text() // Should display: "Hello SwiftSoup"
            } catch {
                return "Error: \(error)"
            }
        }
    }
        

    Step 3: Run the Project

    1. Add SwiftSoupTest.swift to your Swift Playgrounds project.
    2. Run the project.
    3. Click the "Parse HTML" button to extract text from the HTML.

    Expected Output:

    
    SwiftSoup Result:
    Hello SwiftSoup
        

    How It Works

    • Parses HTML using SwiftSoup.parse(html).
    • Extracts text from the HTML structure.
    • Displays the extracted text in a SwiftUI interface.

    Conclusion

    Using SwiftSoup in Swift Playgrounds on iPad is simple with Swift Package Manager. This method allows you to parse HTML, extract elements, and manipulate DOM content within a SwiftUI app. Try modifying the code to experiment with different HTML structures! 🚀
