【SwiftUI】Action Sheet を作ってみる

↓こちらのサイトを参考にして、Action Sheet を作ってみた。

ActionSheet のタイトル部分も、動的に変わるようにしてみたけど、最初の１回だけ値が入らない。バグ？

import SwiftUI
struct ContentView : View {
@State private var selectID:String = ""
@State private var isActionSheetVisible = false
var actionSheet: ActionSheet? {
let button1 = ActionSheet.Button.default(Text("Facebook")) {
self.isActionSheetVisible = false
print("Facebook = " + self.selectID)
}
let button2 = ActionSheet.Button.default(Text("Instagram")) {
self.isActionSheetVisible = false
print("Instagram = " + self.selectID)
}
let button3 = ActionSheet.Button.default(Text("Twitter")) {
self.isActionSheetVisible = false
print("Twitter = " + self.selectID)
}
let dismissButton = ActionSheet.Button.cancel {
self.isActionSheetVisible = false
}
let buttons = [button1, button2, button3, dismissButton]
return self.isActionSheetVisible ? ActionSheet(title: Text("Share " + self.selectID),buttons: buttons) : nil
}
private var uuids: [String] = {
let ids: [String] = Array(0...5).map { _ in
return UUID().uuidString
}
return ids
}()
var body: some View {
NavigationView {
List(uuids.identified(by: \.self)) { uuid in
Button(action: {
self.isActionSheetVisible = true
self.selectID = uuid
}) {
Text(uuid)
}
.presentation(self.actionSheet)
}.navigationBarTitle(Text("List of UUIDs"))
}
}
}
