I am only able to upgrade from Ventura to Sonoma.
I don't want to upgrade, I would like to download the installer so that I can install Sonoma on a separate Volume instead of upgrading.
Am I missing something?
I only see an option to upgrade and the developer website only allows me to download a IPSW file. I have only 1 Mac and I am not sure how I can use the IPSW file to install macOS Sonoma.
Any help would be much appreciated, thanks
Selecting any option will automatically load the page

Overview
I have 2 models: Deparment and Student
Each Department can contain multiple students
Each Student can only be in one Department
I have DepartmentList, tapping on the department should take it to the StudentList which lists all students in the department
Problem
When I use Query in StudentList to filter only students for a specific department id, no students are shown.
Questions:
What should I do to list the students in a department? (see complete code below).
let filter = #Predicate<Student> { student in
student.department?.id == departmentID
}
let query = Query(filter: filter, sort: \.name)
_students = query

Hi,
Overview
I am using Xcode Cloud for my multi platform app.
The macOS test case fails, however the iOS test case runs and succeeds.
I don't have any UI test cases written, the test case are simple and have nothing platform (macOS) specific.
Questions
What can I do to fix this?
Is there any user privileges needed to launch the macOS app for testing? I ask because when I ran the UI tests locally it launched the app and asked for my macOS user password. Just wondering if that is the reason it didn't launch in Xcode Cloud.
Error:

Hi,
Overview:
My app's icon uses Display P3 colors.
The PNG when opened in Preview seems to have the correct colours, but when added to Asset catalog as App icon, the installed app's app icon doesn't have the correct colors.
The Preview app's inspector shows the following:
Colour Model: RGB
Depth: 16
DPI Height: 72
DPI Width: 72
Orientation: 1 (Normal)
Pixel Height: 1,024
Pixel Width: 1,024
Profile Name: Display P3
Steps followed:
I have an app icon that uses the Display P3 color profile.
In Sketch, I have assigned the P3 Display color profile, exported as PNG.
Realised it was using only 8 bits / channel color depth.
So opened PNG in Pixelmator and changed color depth to 16 bits / channel and exported the PNG.
The PNG when opened in Preview seems to have the correct colours, but when used in
I even tried to use Display P3 Gamut in asset catalog and provide the same icon for sRGB and Display P3, yet the installed app's icon's colors don't match
Questions:
What should I do to correct this problem?
Any help would be much appreciated.
Problem
The following code doesn't work:
let predicate = #Predicate<Car> { car in
car.size == size //This doesn't work
}
Console Error
Query encountered an error: SwiftData.SwiftDataError(_error: SwiftData.SwiftDataError._Error.unsupportedPredicate)
Root cause
Size is an enum, #Predicate works with other type such as String however doesn't work with enum
Enum value is saved however is not filtered by #Predicate
Environment
Xcode: 15.0 (15A240d) - App Store
macOS: 14.0 (23A339) - Release Candidate
Steps to reproduce
Run the app on iOS 17 or macOS Sonoma
Press the Add button
Notice that the list remains empty
Expected behaviour
List should show the newly created small car
Actual behaviour
List remains empty inspite of successfully creating the small car.

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 {

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 am logging some messages using Logger
I would like these messages to be printed on to Xcode without the timestamp and other details
I want only the message to be displayed
Questions:
How can I display only the message on the Xcode console (see preferred output)?
Is there a setting in Xcode to remove the timestamp prefix?
Is there an alternate approach?
Note:
I need to use Logger because this app would be released, so print is not an option.
Example Code
import SwiftUI
import os
struct ContentView: View {
let logger = Logger(subsystem: "MyApp", category: "MyCategory")
var body: some View {
Text("Hello, world!")
.onAppear {
logger.debug("content view displayed")
}
}
}
Actual Output:
2022-11-25 18:41:10.116408+0800 Demo[36175:5518724] [MyCategory] content view displayed
Preferred Output:
One of the following would be ideal:
content view displayed
Demo[36175:5518724] [MyCategory] content view displayed
My Failed Attempt
I event tried to use print in debug mode, but couldn't make it compile:
Following is my failed attempt:
import os
#if DEBUG
struct Logger {
let subsystem: String
let category: String
func debug(_ message: String) {
print(message)
}
//This will not help:
// func debug(_ message: OSLogMessage) {
// print(message)
// }
}
#endif

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

I am using Xcode Cloud to create builds.
It contains 2 post actions:
TestFlight Internal Testing - Succeeded
TestFlight External Testing - Failed
Error
Xcode doesn't display the exact error it only shows the status as Not Submitted for Beta Review
When I checked AppStoreConnect > TestFlight I saw the status as Read to Submit. When I manually tried to add external testers to the build using AppStoreConnect website, then I got the error: You can only submit two builds per day to Beta App Review.
Questions
This seems like a very odd limitation. How do we test multiple builds?
Why isn't Xcode the exact error? It only shows Not Submitted for Beta Review

I have a Mac app that uses calendar. When the user has not granted access and still wants to access the calendar I would like to open System Settings Privacy and Security pane for calendar on the mac. How can I do this?
Is it ok to open system settings this way?
Or is there a better way?
I would like to publish this app to the AppStore so want to know if this is ok?
