Ios swift – How to modify share sheet and add custom button in Swift UI

I need to modify the share sheet functionality in my SwiftUI app. I am looking to add a custom button to the share sheet interface. However, I’m facing some challenges in implementing this feature.

Could someone kindly provide guidance or share insights on how to achieve this?

    1. Import Necessary Frameworks:
      In SwiftUI, you typically use UIKit components for this purpose.

    2. Create Share Sheet Functionality:
      Use a SwiftUI Button to trigger the share sheet functionality. Inside the button’s action closure, you can present the share sheet using UIActivityViewController or a similar UIKit component.

    Here’s an example code snippet to get you started:

    import SwiftUI
import UIKit
struct ContentView: View {
    var body: some View {
        Button("Share") {
            guard let url = URL(string: "https://example.com") else { return }
            let activityViewController = UIActivityViewController(activityItems: [url], applicationActivities: nil)
            UIApplication.shared.windows.first?.rootViewController?.present(activityViewController, animated: true, completion: nil)
        }
    }
}

    Replace "https://example.com" with the URL or content you want to share.

    3.Customize Share Sheet Appearance (Optional):
    You can customize the appearance and behavior of the share sheet by configuring the UIActivityViewController instance. For example, you can specify excluded activity types, set a custom title, or customize the appearance of the share sheet on iPad.

    let activityViewController = UIActivityViewController(activityItems: [url], applicationActivities: nil)
activityViewController.excludedActivityTypes = [.airDrop, .assignToContact]
activityViewController.title = "Share Content"

    // Customize further as needed

    4.Handle Share Sheet Completion (Optional):
    If you need to perform any actions or updates after the user completes sharing via the share sheet, you can use the completion handler of UIActivityViewController.

    activityViewController.completionWithItemsHandler = { activityType, completed, returnedItems, error in
    // Handle completion as needed
}

    5.Test and Iterate:
    Test your app to ensure that the custom share button works as expected and that the share sheet appears with the desired content and functionality. Make any adjustments or refinements based on testing and user feedback.

            Text("Share")
        }
        .sheet(isPresented: $isShareSheetPresented, content: {
            // Custom Share Sheet
            ShareSheet(activityItems: ["Hello, world!"])
        })
    }
}

struct ShareSheet: View {
    var activityItems: [Any]

    var body: some View {
        VStack {
            Text("Share")
                .font(.title)
                .padding()

            Button(action: {
                // Handle your custom action
                print("Custom action tapped")
            }) {
                Text("Custom Action")
            }
            .padding()

            Divider()

            Button(action: {
                // Share functionality
                let activityViewController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)
                UIApplication.shared.windows.first?.rootViewController?.present(activityViewController, animated: true, completion: nil)
            }) {
                Text("Share")
                    .foregroundColor(.blue)
            }
            .padding()

            Spacer()
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
