Create a share sheet in iOS 15 with swiftUI

I am trying to create a share sheet to share a Text, it was working fine in iOS 14 but in iOS 15 it tells me that

'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead.

how can I make it work on iOS 15 with SwiftUI

Button { let TextoCompartido = "Hola ๐Ÿ˜€ " let AV = UIActivityViewController(activityItems: [TextoCompartido], applicationActivities: nil) UIApplication.shared.windows.first?.rootViewController?.present(AV, animated: true, completion: nil)
}

I think you would be best served using SwiftUI APIs directly. Generally, I would follow these steps.

  1. Create SwiftUI View named ActivityView that adheres to UIViewControllerRepresentable. This will allow you to bring UIActivityViewController to SwiftUI.
  2. Create an Identifiable struct to contain the text you'd like to display in the ActivityView. Making this type will allow you to use the SwiftUI sheet API and leverage SwiftUI state to tell the app when a new ActivityView to be shown.
  3. Create an optional @State variable that will hold on to your Identifiable text construct. When this variable changes, the sheet API will perform the callback.
  4. When the button is tapped, update the state of the variable set in step 3.
  5. Use the sheet API to create an ActivityView which will be presented to your user.

The code below should help get you started.


import UIKit
import SwiftUI
// 1. Activity View
struct ActivityView: UIViewControllerRepresentable { let text: String func makeUIViewController(context: UIViewControllerRepresentableContext<ActivityView>) -> UIActivityViewController { return UIActivityViewController(activityItems: [text], applicationActivities: nil) } func updateUIViewController(_ uiViewController: UIActivityViewController, context: UIViewControllerRepresentableContext<ActivityView>) {}
}
// 2. Share Text
struct ShareText: Identifiable { let id = UUID() let text: String
}
struct ContentView: View { // 3. Share Text State @State var shareText: ShareText? var body: some View { VStack { Button("Show Activity View") { // 4. New Identifiable Share Text shareText = ShareText(text: "Hola ๐Ÿ˜€") } .padding() } // 5. Sheet to display Share Text .sheet(item: $shareText) { shareText in ActivityView(text: shareText.text) } }
}

Tested in in iOS 15 with SwiftUI

 func shareViaActionSheet() { if vedioData.vedioURL != nil { let activityVC = UIActivityViewController(activityItems: [vedioData.vedioURL as Any], applicationActivities: nil) UIApplication.shared.currentUIWindow()?.rootViewController?.present(activityVC, animated: true, completion: nil) } }

To avoid iOS 15 method deprecation warning use this extension

public extension UIApplication { func currentUIWindow() -> UIWindow? { let connectedScenes = UIApplication.shared.connectedScenes .filter { $0.activationState == .foregroundActive } .compactMap { $0 as? UIWindowScene } let window = connectedScenes.first? .windows .first { $0.isKeyWindow } return window }
}

iOS 16 includes the ShareLink view which works like this:

Gallery(...) .toolbar { ShareLink(item: image, preview: SharePreview("Birthday Effects")) }

To avoid warning, change the way you retrieve the window scene. Do the following:

Button { let TextoCompartido = "Hola ๐Ÿ˜€ " let AV = UIActivityViewController(activityItems: [TextoCompartido], applicationActivities: nil) let scenes = UIApplication.shared.connectedScenes let windowScene = scenes.first as? UIWindowScene windowScene?.keyWindow?.rootViewController?.present(AV, animated: true, completion: nil)
}

you could try the following using the answer from: How to get rid of message " 'windows' was deprecated in iOS 15.0: Use UIWindowScene.windows on a relevant window scene instead" with AdMob banner?

Note that your code works for me, but the compiler give the deprecation warning.

public extension UIApplication { func currentUIWindow() -> UIWindow? { let connectedScenes = UIApplication.shared.connectedScenes .filter({ $0.activationState == .foregroundActive}) .compactMap({$0 as? UIWindowScene}) let window = connectedScenes.first? .windows .first { $0.isKeyWindow } return window }
}
struct ContentView: View { let TextoCompartido = "Hola ๐Ÿ˜€ " var body: some View { Button(action: { let AV = UIActivityViewController(activityItems: [TextoCompartido], applicationActivities: nil) UIApplication.shared.currentUIWindow()?.rootViewController?.present(AV, animated: true, completion: nil)
// This works for me, but the compiler give the deprecation warning
// UIApplication.shared.windows.first?.rootViewController?.present(AV, animated: true, completion: nil) }) { Text("Hola click me") } }
}

// iOS 16+, Swift 5

var rootViewController: UIViewController? { let connectedScenes = UIApplication.shared.connectedScenes .filter { $0.activationState == .foregroundActive } .compactMap { $0 as? UIWindowScene } let window = connectedScenes.first?.windows.first { $0.isKeyWindow } let rootViewController = window?.rootViewController return rootViewController
}
func topViewController(of viewController: UIViewController? = rootViewController) -> UIViewController? { if let navigationController = viewController as? UINavigationController { return topViewController(of: navigationController.visibleViewController) } if let tabController = viewController as? UITabBarController { if let selected = tabController.selectedViewController { return topViewController(of: selected) } } if let presented = viewController?.presentedViewController { return topViewController(of: presented) } return viewController
}
