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
