Hello everyone, I am new to the Swift and the SwiftUI. Trying to understand how sorting works on SwiftUI Table view. The following code does what I intend to do, but I am not able to understand how does it actually work. Need help with the answers for the questions posted below the code. import SwiftUI struct Person: Identifiable {     let givenName: String     let familyName: String     let emailAddress: String     let id = UUID() } private var people = [     Person(givenName: "f1", familyName: "l1", emailAddress: "e1@example.com"),     Person(givenName: "f2", familyName: "l2", emailAddress: "e2@example.com"),     Person(givenName: "f3", familyName: "l3", emailAddress: "e3@example.com") ] struct ContentView: View {     @State private var selected = Set<Person.ID>()  // Question 1     @State private var sortOrder = [KeyPathComparator(\Person.givenName)]     var body: some View {         Table(people, selection: $selected, sortOrder: $sortOrder) {             TableColumn("Given name", value: \.givenName)             TableColumn("Family name", value: \.familyName)             TableColumn("Email", value: \.emailAddress)         } // Question 2         .onChange(of: sortOrder) { newOrder in             people.sort(using: newOrder)         }     } } Question 1 : I want to be able to sort by all the columns. How many KeyPathComparators should be in the sortOrder array? Question 2: What is the value of newOrder? Is it same as the sortOrder? What does it contain? Question 3: sortOrder contains the comparator for only givenName. How does the above code able to provide sort functionality for all the columns?

Hello everyone, I am new to the app development. My goal is to develop professional apps for the MacOS. I have learned some Swift and SwiftUI on my own. Also, watched some videos here and there. Apple tutorials are also scattered. I feel I know some things, but not enough to create the apps that I want. A lot of my time goes into searching things, which kills my interest. Is there a learning path (things to learn in sequence) for MacOS app development? Example: learn swift learn swiftUI design patterns? some frameworks, maybe? Please suggest. Thanks,

In the following code, click/touch anywhere on any row of the list deletes that row. This is not expected. Only the click/touch on the "xmark" button should delete that row. import SwiftUI struct MainView: View { private let arr: [String] = ["one", "two", "three"] var body: some View { List(arr, id: \.self) {item in SecView(name: item) } } } struct SecView: View { var name: String @State private var show = true var body: some View { if show { HStack { Text(name) Button(action: { show = false }, label: { Image(systemName: "xmark") }) .border(.yellow) } } } } @main struct XApp: App { var body: some Scene { WindowGroup { MainView() } } } Please check. I ran the above code for iPAD air (5th generation).

Hello and thanks for reading my post. I have a SwiftUI view, the users should be able to click a button and take printout of that view. Clicking on the button should open the standard print sheet (select printer, pages, layout, etc.). How can I implement such a functionality? I have been trying hard without any success. Please help. It is an iPad app, using Xcode 14.3

Hello and thanks for reading my post. I have been trying hard to generate a PDF from a SwiftUI view on a button press. Looked at the PDFKit documentation, understood that PDFView, PDFDocument and PDFPage are important classes. However, I couldn't find any examples of how to use them in SwiftUI or Swift. Basically, given a SwiftUI view (or a Swift struct), how to create a new SwiftUI view that displays the generated PDF? The pdf can contain charts, layouts, etc.
