Overview I have an existing Xcode project that works fine with Xcode Cloud I have a separate branch on to which I have migrated and made changes for Xcode 14 On the same branch I have made some code changes that is supported by Swift 5.7 Example: var price: Int? = 100 guard let price else { return } Problem Xcode code build fails with the error Variable binding in a condition requires an initializer Question: Is it possible to build Xcode Cloud on Swift 5.7 or Xcode 14?

Hi, My lab appointment status is pending. The lab is for tomorrow. When would I get to know if my lab appointment has been accepted. It is my first time for a lab appointment, also I forgot to mention the feedback IDs, would there be a way to amend the request to include the feedback IDs if that would help. (Feedback assistant was down when I booked an appointment so couldn't get the feedback IDs.) Any help would be much appreciated as I am from a different timezone and would need to plan accordingly .... really praying I get an appointment

I am a bit confused about tasks being cancelled. Overview: checkCancellation function has 2 child tasks: computeA and computeB that run concurrently, computeB throws an error. Doubt: I expected child task computeA to be cancelled because computeB threw an error, but computeA was never cancelled. Is my understanding wrong or am I missing something? Or is this a bug? Note: I am using a SwiftUI project (as Swift Playgrounds don't support async let) macOS Big Sur 11.5.2 (20G95) Xcode Version 13.0 beta 5 (13A5212g) Output: A - started B - going to throw A - going to return, Task.isCancelled = false error: infinity Concurrent Function Definitions: import Foundation import UIKit enum ComputationError: Error { case infinity } fileprivate func computeA() async throws -> Int { print("A - started") await Task.sleep(2 * 100_000_000) print("A - going to return, Task.isCancelled = \(Task.isCancelled)") //I expected Task.isCancelled to be true return 25 } fileprivate func computeB() async throws -> Int { print("B - going to throw") throw ComputationError.infinity } func checkCancellation() async throws { async let a = computeA() async let b = computeB() let c = try await a + b print("c = \(c)") } Invoking Concurrent function struct ContentView: View { var body: some View { Button("check cancellation") { Task { do { try await checkCancellation() print("normal exit") } catch { print("error: \(error)") } } } } }

Aim To use a keyboard shortcut on a Multiplatform app (iOS and macOS) When keyboard shortcut is tapped, the price needs to be printed Problem The same code doesn't work on iPad but works on macOS Question: Why is not working? How to fix this? Environment macOS Big Sur - 11.6 (20G165) Version 13.0 (13A233) Code @main struct TestApp: App { @State private var price = 0 var body: some Scene { WindowGroup { ContentView(price: $price) .focusedValue(\.price, $price) } .commands { PriceCommands() } } } struct ContentView: View { @Binding var price: Int var body: some View { IncreasePriceButton(price: $price) } } struct IncreasePriceButton: View { @Binding var price: Int var body: some View { Button("Increase Price") { price += 1 print("price = \(price)") } } } struct PriceCommandButton: View { @FocusedBinding(\.price) var price var body: some View { Button("Print Price") { print("price = \(price)") } } } struct PriceCommands: Commands { var body: some Commands { CommandMenu("Custom") { PriceCommandButton() .keyboardShortcut(KeyboardShortcut("C", modifiers: [.command, .shift])) } } } struct FocusedPriceKey: FocusedValueKey { typealias Value = Binding<Int> } extension FocusedValues { var price: FocusedPriceKey.Value? { get { self[FocusedPriceKey.self] } set { self[FocusedPriceKey.self] = newValue } } }
