Understanding Which Activity Gets Called in Sharing SwiftUI - swiftui

Question

On my share sheet I see those activities but I want to understand and fetch which activity is selected to share the url.
For example, if WhatsApp is selected I want to fetch WhatsApp selected bool somehow.
struct ShareSheet: UIViewControllerRepresentable {
typealias Callback = (_ activityType: UIActivity.ActivityType?, _ completed: Bool, _ returnedItems: [Any]?, _ error: Error?) -> Void
let activityItems: [Any]
let applicationActivities: [UIActivity]? = nil
let excludedActivityTypes: [UIActivity.ActivityType]? = nil
let callback: Callback? = nil
func makeUIViewController(context: Context) -> UIActivityViewController {
let controller = UIActivityViewController(
activityItems: activityItems,
applicationActivities: applicationActivities)
controller.excludedActivityTypes = excludedActivityTypes
controller.completionWithItemsHandler = callback
return controller
}
func updateUIViewController(_ uiViewController: UIActivityViewController, context: Context) {
// nothing to do here
}
}
What I am trying is
func fetchActivity() {
if activityItems.description == "whatsapp" {
self.service.articleShare(article_id: articlePost.article_id, share_type: "whatsapp")
}
}

struct ShareSheet: UIViewControllerRepresentable {
#ObservedObject var service = ArticleService()
var articlePost: Article
typealias Callback = (_ activityType: UIActivity.ActivityType?, _ completed: Bool, _ returnedItems: [Any]?, _ error: Error?) -> Void
let activityItems: [Any]
let applicationActivities: [UIActivity]? = nil
let excludedActivityTypes: [UIActivity.ActivityType]? = nil
let callback: Callback? = nil
func makeUIViewController(context: Context) -> UIActivityViewController {
let controller = UIActivityViewController(
activityItems: activityItems,
applicationActivities: applicationActivities)
controller.excludedActivityTypes = excludedActivityTypes
controller.completionWithItemsHandler = callback
controller.completionWithItemsHandler = { activity, success, items, error in
if !success{
print("cancelled")
return
}
if activity == UIActivity.ActivityType.postToTwitter {
print("twitter")
print(articlePost.article_id)
self.service.articleShare(article_id: articlePost.article_id, share_type: "twitter")
}
if activity == UIActivity.ActivityType.postToFacebook {
print("facebook")
self.service.articleShare(article_id: articlePost.article_id, share_type: "facebook")
}
if activity == UIActivity.ActivityType.mail {
print("mail")
print(articlePost.article_id)
self.service.articleShare(article_id: articlePost.article_id, share_type: "mail")
}
if activity == UIActivity.ActivityType.message {
}
}
return controller
}
func updateUIViewController(_ uiViewController: UIActivityViewController, context: Context) {
// nothing to do here
}
}
