A SwiftUI view for presenting a `SFSafariViewController` with a URL Binding that presents nicely in the UI.

SafariView.swift

import SwiftUI
import SafariServices

public struct SafariView: View {
    @Binding var url: URL?
    var entersReaderIfAvailable: Bool = false
    
    public var body: some View {
        SafariViewRepresentable(url: $url, enterReader: entersReaderIfAvailable)
            .navigationBarHidden(true)
            .ignoresSafeArea()
    }
}

fileprivate struct SafariViewRepresentable: UIViewControllerRepresentable {
    @Binding var url: URL?
    let enterReader: Bool
    
    func makeUIViewController(context: Context) -> SFSafariViewController {
        let config = SFSafariViewController.Configuration()
        config.entersReaderIfAvailable = enterReader
        
        let vc = SFSafariViewController(url: url!, configuration: config)
        vc.delegate = context.coordinator
        
        return vc
    }
    
    func updateUIViewController(_ controller: SFSafariViewController, context: UIViewControllerRepresentableContext<SafariViewRepresentable>) { }
    
    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }
}

extension SafariViewRepresentable {
    fileprivate final class Coordinator: NSObject, SFSafariViewControllerDelegate {
        let parent: SafariViewRepresentable
        
        init(_ parent: SafariViewRepresentable) {
            self.parent = parent
        }
        
        func safariViewControllerDidFinish(_ controller: SFSafariViewController) {
            parent.url = nil
        }
    }
}

FYI this is iOS 14.0+ just replace .ignoresSafeArea() with .edgesIgnoringSafeArea(.all) for iOS 13.X

Hey Tommy -- thank you for this, it is exactly what I needed. I tried a few other approaches google found and they didn't work as advertised. Yours worked first time without hitch.

Is there a way to prevent having the SFSafariViewController save session cookies using this method? Or alternatively, wiping out any session cookies prior to displaying the view?

I'm using this for OAuth login to a site I don't control and the cookies seem to be persisted during the lifetime of my app executing. Restarting the app results in no cookies, so they appear to be cleaned up at app shutdown.
