The following program should run the function longCalculation twice in parallel if the button is pressed. But the function is called twice in sequence instead. struct ContentView: View {     @State private var result: Int = 0     var body: some View {         VStack {             Text("Result: \(result)")             Button {                 async {                     async let result1 = longCalculation()                     async let result2 = longCalculation(                     self.result = await result1 + result2                     print("[end] action / is on main: \(Thread.current.isMainThread)")                 }             } label: {                 Text("Button")             }         }     } } fileprivate func longCalculation() async -> Int {     print("[start] longCalculation / is on main thread: \(Thread.current.isMainThread)")     var c = 0     for _ in 0...10000000 {         c += Int.random(in: 0...100)         c = c % 13     }     print("[end] longCalculation / is on main thread: \(Thread.current.isMainThread)")     return c } According to the output the calls are still in sequence. Why does this happen? The two async let assignments should create two child tasks. Did I miss something? > [start] longCalculation / is on main thread: false > [end] longCalculation / is on main thread: false > [start] longCalculation / is on main thread: false > [end] longCalculation / is on main thread: false > [end] action / is on main: true

The following code shows that a selected button in a list gots blurred if a glass effect is applied to the list. This happens if the button style is plain or glass. It does not happen if the button style is bordered. Is this a wanted documented behavior or is this a bug? struct ContentView: View { @State private var items = [ "Item 1", "Item 2", "Item 3", "Item 4"] var body: some View { ZStack { Image(systemName: "globe") .resizable() List(items, id: \.self) { item in Button(action: {}, label: { Text(item) }) } .padding() .glassEffect(in: Rectangle()) } } }
