Showing 'UIActivityViewController' in SwiftUI

Question

I want to let the user to be able to share a Location but I don't know how to show UIActivityViewController in Swift UI

Answer 1

The basic implementation of UIActivityViewController in SwiftUI is

import UIKit
import SwiftUI

struct ActivityViewController: UIViewControllerRepresentable {

    var activityItems: [Any]
    var applicationActivities: [UIActivity]? = nil

    func makeUIViewController(context: UIViewControllerRepresentableContext<ActivityViewController>) -> UIActivityViewController {
        let controller = UIActivityViewController(activityItems: activityItems, applicationActivities: applicationActivities)
        return controller
    }

    func updateUIViewController(_ uiViewController: UIActivityViewController, context: UIViewControllerRepresentableContext<ActivityViewController>) {}

}

And here is how to use it.

struct MyView: View {

    @State private var isSharePresented: Bool = false

    var body: some View {
        Button("Share app") {
            self.isSharePresented = true
        }
        .sheet(isPresented: $isSharePresented, onDismiss: {
            print("Dismiss")
        }, content: {
            ActivityViewController(activityItems: [URL(string: "https://www.apple.com")!])
        })
    }
}
