column

Thinking of trying to code a 3d engineering design software. I know it won't be easy to code. The basic idea is the user is given an interactive 3d interface, and the user can move through the 3d space, drag and drop columns beams etc, select deselect dragged or created items, assign values to it, dimensions etc. The user should be able to change sizes of elements (like when user type 10 width, the beam should change it's size to the typed value etc), get fixed to other elements etc. Any idea which documentation should I look at for xcode, swiftui to get an idea or first few steps into interactive 3d etc?

Hi,i have been trying out SwiftUI Table and wanted to present a details view when click on Table Row occurs, but I couldn't figure out how to deselect row once its been selected, while it may not be what Table was intended for, but I still think this code should be valid. (iPadOS) struct Person: Identifiable { let givenName: String let familyName: String let emailAddress: String let id = UUID() } private var people = [ Person(givenName: Juan, familyName: Chavez, emailAddress: juanchavez@icloud.com), Person(givenName: Mei, familyName: Chen, emailAddress: meichen@icloud.com), Person(givenName: Tom, familyName: Clark, emailAddress: tomclark@icloud.com), Person(givenName: Gita, familyName: Kumar, emailAddress: gitakumar@icloud.com) ] @State private var selectedPeople: Person.ID? @State private var detailsViewPresented: Bool = false var body: some View { Table(people, selection: $selectedPeople) { TableColumn(Given Name, value: .givenName) TableColumn(Family Name, value: .familyName) TableColumn(E-Mail Address, va

I need help with this topic please. I'm interested in the three column layout version. Column one I want my list of Core Data Entities, Column two I want a list of my Core Data Entity's ListView items, and for Column three I want the detail view of the selected list view item. Any help on figuring out the best way to accomplish this would be much appreciated. Thanks

The device UDID was registered to the developer account 40 hours ago, the STATUS column was processing in the first 24 hours, then turned to empty. But I still can't run my app (with distribution method development), when I try to run it after download it through my OTA URL, it prompts “the app cannot be installed because its integrity could not be verified” but everything runs good on a iPhone which was registered a month ago. What should I do now? keep waiting?

My code is import SwiftUI struct ContentView: View { var emojis = [🚂, 🤡, 🚀, 🚁, 🚕, 😅, ✅, 👍, 🥳, 🎃] @State var emojiCount = 6 var body: some View { VStack { ScrollView { LazyVGrid(columns: [GridItem(.adaptive(minimum: 65))]) { ForEach(emojis[0.. 1 { emojiCount -= 1 } }, label: { Image(systemName: minus.circle) }) } var add: some View { Button { if emojiCount < emojis.count { emojiCount += 1 } } label: { Image(systemName: plus.circle) } } } struct CardView: View { var content: String @State var isFaceUp: Bool = true var body: some View { ZStack { let shape = RoundedRectangle(cornerRadius: 20) if isFaceUp { shape.fill().foregroundColor(.white) shape.strokeBorder(lineWidth: 3) Text(content) .font(.largeTitle) } else { shape.fill() } } .onTapGesture { isFaceUp = !isFaceUp } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() .preferredColorScheme(.light) ContentView() .preferredColorScheme(.dark) } } Then I get Actually, the spacing between rows is t

I tried to update the UISplitViewController in my old iOS project to use the newer column-based API, but noticed that when setting the Style to Double Column in IB from the currently selected Unspecified (Discouraged), the swipe gesture doesn't show and hide the master view controller anymore, even if the option Presents Primary With Gesture is selected. This also happens with a fresh project where I dragged the standard split view controller into the IB canvas as the initial view controller. Is this expected or am I missing something?

I'm trying to use the refreshable modifier on a Scrollview in an app that targets iOS 16. But the asynchronus task gets cancelled during the pull to refresh gesture. It was tested on a physical device. Here is some code that demonstrates the problem and an image with the error printed: ExploreViewModel.swift class ExploreViewModel: ObservableObject { @Published var randomQuotes: [Quote] = [] init() { Task { await loadQuotes() } } @MainActor func loadQuotes() async { let quotesURL = URL(string: https://type.fit/api/quotes)! do { let (data, urlResponse) = try await URLSession.shared.data(from: quotesURL) guard let response = urlResponse as? HTTPURLResponse else { print(no response); return} if response.statusCode == 200 { let quotes = try JSONDecoder().decode([Quote].self, from: data) randomQuotes.append(contentsOf: quotes) } } catch { debugPrint(error) debugPrint(error.localizedDescription) } } func clearQuotes() { randomQuotes.removeAll() } } Content.swift import SwiftUI struct ContentView: View { @StateObjec

Hi. I am having issues with json parsing. all my source data use double quote except for one. here is the sample do { let json = [['16772', 'Cebu', 'Philippines']] if let jsonArray = try JSONSerialization.jsonObject(with: Data(json.utf8), options: []) as? [[Any]] { print(Hello World) } } catch { print(error) } if the json string is let json = [[16772, Cebu, Philippines]] it works ok. but if it is single quote, then it gives out the error message Error Domain=NSCocoaErrorDomain Code=3840 Invalid value around line 1, column 2. UserInfo={NSDebugDescription=Invalid value around line 1, column 2., NSJSONSerializationErrorIndex=2} What am i missing to enable parsing single quote normally? Thoughts?

I use Core Data with two entities: Set and Link. Both entities contain a UUID id. Sets can contain 1 or more Links and this is represented in a 1-many relationship When the user wants to delete ALL links, this code is called for link in learningSet.webLinksArray.reversed(){ container.viewContext.delete(link) } do{ try container.viewContext.save() } catch let error { print(Failure deleting all links } Here is the view code that renders link if !learningSet.webLinksArray.isEmpty{ LazyVGrid(columns: columns, alignment: .center, spacing: 16, pinnedViews: []) { ForEach(learningSet.webLinksArray, id: .id) { link in RichWebLinkView(webLink: link) } } } It all works, but I get the following error/warning in the console ForEach, _FlexFrameLayout>>: the ID nil occurs multiple times within the collection, this will give undefined results! LazyVGridLayout: the ID nil is used by multiple child views, this will give undefined results! It's unclear why the LazyVGrid is even being re-rendered when the
