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 Complete code App @main struct SchoolApp: App { var body: some Scene { WindowGroup { ContentView() } .modelContainer(for: [Department.self, Student.self]) } } Department import Foundation import SwiftData @Model class Department { var id: UUID var name: String var students: [Student] init( id: UUID, name: String, students: [Student] = [] ) { self.id = id self.name = name self.students = students } } Student import Foundation import SwiftData @Model class Student { var id: UUID var name: String @Relationship(inverse: \Department.students) var department: Department? init( id: UUID, name: String, department: Department? = nil ) { self.id = id self.name = name self.department = department } } ContentView import SwiftUI struct ContentView: View { @State private var selectedDepartment: Department? var body: some View { NavigationSplitView { DepartmentList(selectedDepartment: $selectedDepartment) } detail: { if let department = selectedDepartment { StudentList(department: department) } else { Text("no department selected") } } .task { printStoreFilePath() } } private func printStoreFilePath() { let urls = FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask) if let path = urls.map({ $0.path(percentEncoded: false) }).first { print("Storage: \(path)") } } } DepartmentList import SwiftUI import SwiftData struct DepartmentList: View { @Binding var selectedDepartment: Department? @Query(sort: \.name) private var departments: [Department] @Environment(\.modelContext) private var modelContext var body: some View { List(selection: $selectedDepartment) { ForEach(departments) { department in NavigationLink(value: department) { Text(department.name) } } } .toolbar { ToolbarItem { Button { addDepartment() } label: { Label("Add", systemImage: "plus") } } } } private func addDepartment() { guard let index = (1000..<10000).randomElement() else { return } let department = Department(id: UUID(), name: "Department \(index)") modelContext.insert(department) } } StudentList import SwiftUI import SwiftData struct StudentList: View { var department: Department @Query private var students: [Student] @Environment(\.modelContext) private var modelContext init(department: Department) { self.department = department let departmentID = department.id let filter = #Predicate<Student> { student in student.department?.id == departmentID } let query = Query(filter: filter, sort: \.name) _students = query } var body: some View { List { ForEach(students) { student in Text(student.name) } } .toolbar { ToolbarItem { Button { addStudent() } label: { Label("Add", systemImage: "plus") } } } } private func addStudent() { guard let index = (1000..<10000).randomElement() else { return } let student = Student( id: UUID(), name: "Student \(index)", department: department ) modelContext.insert(student) } }

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

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 import SwiftUI import PlaygroundSupport 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 ?

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

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) guard let string = String(data: data, encoding: .utf8) else { print("Failed to convert data to string") return } let b64Text = string .replacingOccurrences(of: "-----END PRIVATE KEY-----", with: "") .replacingOccurrences(of: "-----BEGIN PRIVATE KEY-----", with: "") .replacingOccurrences(of: "\n", with: "") guard let b64Data = b64Text.data(using: .utf8), let decodedData = Data(base64Encoded: b64Data) else { print("Was not b64 data") return } print(string) var outArray : CFArray? let filename : CFString? = nil var inputFormat = SecExternalFormat.formatUnknown var itemType = SecExternalItemType.itemTypePrivateKey let flags = SecItemImportExportFlags() //I tried data, b64Data, decodedData all seems to return an error let status = SecItemImport(decodedData as CFData, filename, &amp;inputFormat, &amp;itemType, flags, nil, nil, &amp;outArray) //status = -25257 print("status = \(status)") for element in (outArray as [AnyObject]?) ??
