Overview
I have a 3 column NavigationSplitView
On iPad I would like to detect if the sidebar (red) / content (green) is a slide over
I don't want to rely on orientation as it is possible to have multiple apps side by side and that can change the view size
Questions:
On iPad, how can I detect if sidebar (red) / content (green) is a slide over?
Or is there an alternate approach?
Code:
struct ContentView: View {
@State private var splitViewVisibility = NavigationSplitViewVisibility.automatic
var body: some View {
NavigationSplitView(columnVisibility: $splitViewVisibility) {
Color.red
} content: {
Color.green
} detail: {
Color.blue
}
}
}

Hi,
When using NSPersistentCloudKitContainer lots of error / debug messages are shown in Xcode Debug area.
Feedback FB11794798:
Overview
When I use NSPersistentCloudKitContainer I get the following error / debug messages printed on the Xcode Debug Area.
Syncing seems to happen fine.
Tested on device and simulator.
I am still using Development (not deployed to Production yet)
I even tried with a new project using the default code generated for by enabling CloudKit coredata sync and I still get the same messages.
I have filed a feedback FB11794798
Steps to Reproduce
Create a new project check Use CoreData and Host in CloudKit check boxes
Run the project
Notice the error messages shown below.
Questions
How to resolve these errors?
Or is this a bug from the Apple Frameworks? (Feedback FB11794798)

Hi,
I have an Xcode project that uses Xcode 14.0 beta 6 (14A5294g).
How to make Xcode Cloud compile code compiled in Xcode beta?
My code uses beta APIs that doesn't seem to compile on Xcode Cloud (throws compilation errors)
Am I missing something as this would be a common scenario for many developers?
How do I make the beta APIs compile on Xcode Cloud?

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)")
}

Aim:I have a model which is an ObservableObject. It has a Bool property, I would like to use this Bool property to initialise a @Binding variable.Questions:How to convert an @ObservableObject to a @Binding ?Is creating a @State the only way to initialise a @Binding ?Note:I do understand I can make use of @ObservedObject / @EnvironmentObject, and I see it's usefulness, but I am not sure a simple button needs to have access to the entire model.Or is my understanding incorrect ?Code:import SwiftUI
import Combine

class Car : ObservableObject {
@Published var isReadyForSale = true
}
struct SaleButton : View {
@Binding var isOn : Bool
var body: some View {
Button(action: {
self.isOn.toggle()
}) {
Text(isOn ? "On" : "Off")
}
}
}
let car = Car()
//How to convert an ObservableObject to a Binding
//Is creating an ObservedObject or EnvironmentObject the only way to handle a Observable Object ?
let button = SaleButton(isOn: car.isReadyForSale) //Throws a compilation error and rightly so, but how to pass it as a Binding variable ?

Hi,I am trying to extract the data from the P8 file to use it generate JWT.I understand that it is possible using dumpasn1 and extracting the OCTET STRING section. This is great, and is definitely possible.I was wondering if it was possible to do it on macOS using Apple's APIs (example SecItemImport), would make it simpler if it was possible all in the mac app.I tried the following but it didn't work:Error: I got the OSStatus as -25257Questions:- Is there a way to do this using SecItemImport or any other Apple APIs as I am using it in a command line mac app ?- Are the parameters to SecItemImport are incorrect ?- Am down the wrong path? , any direction to the correct API would help.What I tried with SecItemImport:- Data extracted from the file- Decoding the data from the file- Some input formatsMany thanks.import Foundation
import Security
func f1() {
do {
let fileURL = URL(fileURLWithPath: "some valid path");
let data = try Data(contentsOf: fileURL)

print("Failed to convert data to string")
return

Hi,I would like to create a JWT to interact with Apple's Webservices.As the first step, I have a private key file, I have loaded it as Data.I would like to create an instance of Private Key instance (not sure what is the correct struct to use, tried HMAC, P256.Signing.PrivateKey etc)Every time an exception is thrown.Any help and direction would greatly help. Many thanks.let privateKeyPath = URL(fileURLWithPath: "some valid path")
let privateKeyData = try Data(contentsOf: privateKeyPath, options: .alwaysMapped)
let message = "abcd"
let messageData = message.data(using: .utf8)!
do {
//Option1:
//This throws: Error: incorrectParameterSize
let signature1 = try P256.Signing.ECDSASignature(rawRepresentation: privateKeyData)
//Option2:
let key2 = SymmetricKey(data: privateKeyData)
//This throws: Error: incorrectKeySize

I would like to display an alert, when the user dismisses the alert the next alert should be displayed.
If the user doesn't dismiss the first alert, the 2nd alert should wait till the user dismisses the first alert
Functionality like back pressure.
My Attempt:
Given below is code where I have attempted to do it based on an @ObservedObject and @Published property.
Problem:
Alerts are displayed but they don't wait for the alert to be dismissed.
Code:
ContentView:
import SwiftUI
struct ContentView: View {
@ObservedObject var model = Model()
var body: some View {
Text("Hello World!")
.alert(item: $model.employee, content: makeAlert(forEmployee:))
}
private func makeAlert(forEmployee employee: Employee) -> Alert {
let dismissButton = Alert.Button.cancel((Text("Ok")))
return Alert(title: Text("New Employee"),
message: Text(employee.name),
dismissButton: dismissButton)
}
}
Model:
import Foundation
class Model : ObservableObject {
@Published var employee : Employee?
private var index = 0
private lazy var timer = {
Timer.scheduledTimer(withTimeInterval: 3, repeats: true) { [weak self] timer in
self?.createNewEmployee()
print("fired for \(self?.employee?.name ?? "none")")
}
}()
init() {
timer.fire()
}
func createNewEmployee() {
guard let unicodeScalar = UnicodeScalar(index + 65) else {
return
}
let name = String(Character(unicodeScalar))
employee = Employee(id: index,
name: name)
index += 1
}
}
Employee:
import Foundation
class Employee : Identifiable {
var id : Int
var name : String
init(id: Int, name: String) {
self.id = id
self.name = name
}
}
