Safari View in SwiftUI
This project demonstrates how to display a Safari view controller or a custom QR code view controller in SwiftUI using UIViewControllerRepresentable.
About
The SafariView struct wraps up the logic to display a URL in a view controller. If the SafariServices framework is available, it will display the URL in a SFSafariViewController. Otherwise, it falls back to a custom QRCodeViewController that generates a QR code image for the URL.
This allows integrating a Safari or QR code UIKit view controller into a SwiftUI view in a seamless way.
Usage
To display a Safari view:
SafariView(url: URL(string: "https://www.example.com")!)
To display a QR code view:
SafariView(url: URL(string: "https://www.example.com")!)
// SafariServices not available
The SafariView wrapper handles instantiating the correct view controller under the hood.
Implementation
The key aspects are:
SafariView conforms to UIViewControllerRepresentable to create and update a UIViewController SafariServices availability is checked with canImport compile time check SFSafariViewController is used when available, otherwise defaults to QRCodeViewController QRCodeViewController generates a QR code image from the URL
