How to solve this error? Also I want to create a Label that shows word:'Result:'and a variable called calresult but I don't know how to make the Label, can anyone give me the code to create the Label I said? I hope the Label will show these text, (calresult)means the data in calresult: Result: (calresult)

Hello there, I stumbled on the issue of observing UserDefaults. My need is to "listening"/observing UD key named "com.apple.configuration.managed" which is responsible for reading provided MDM external plist. I checked that on the opened app it is possible to provide that plist, and app read this payload correctly. My problem is to observing that change, when plist is uploading. Requirement is to support iOS 13, this is why I can't use AppStorage. Despite using some similar solutions like: someone own implementation of AppStorage, and using StackOverflow solutions like this, it still doesn't work. My, I feel, the closest one solution was:   @objc dynamic var mdmConfiguration: Dictionary<String, String> {     get { (dictionary(forKey: MDM.ConfigurationPayloadKey) != nil) ? dictionary(forKey: MDM.ConfigurationPayloadKey)! as! Dictionary<String, String> : Dictionary<String, String>() }     set { setValue(newValue, forKey: MDM.ConfigurationPayloadKey)}   } } class MDMConfiguration: ObservableObject {       //@Binding private var bindedValue: Bool       @Published var configuration: Dictionary = UserDefaults.standard.mdmConfiguration {     didSet {       UserDefaults.standard.mdmConfiguration = configuration     //  bindedValue.toggle()     }   }   private var cancelable: AnyCancellable?   init() {  // init(toggle: Binding<Bool>) {     //_bindedValue = toggle     cancelable = UserDefaults.standard.publisher(for: \.mdmConfiguration)       .sink(receiveValue: { [weak self] newValue in         guard let self = self else { return }         if newValue != self.configuration { // avoid cycling !!           self.configuration = newValue         }       })   } } struct ContentView: View {       @State private var isConfigurationAvailable: Bool = false   @State private var showLoadingIndicator: Bool = true   @ObservedObject var configuration = MDMConfiguration()       var body: some View {           GeometryReader { geometry in               let width = geometry.size.width       let height = geometry.size.height                             VStack {         Text("CONTENT -> \(configuration.configuration.debugDescription)").padding()         Spacer()         if !configuration.configuration.isEmpty {           Text("AVAILABLE").padding()         } else {           Text("NIL NULL ZERO EMPTY")             .padding()         }       }        }   } } But it still doesn't ensure any changes in view, when I manually click on f.e. button, which prints the configuration in the console when it has uploaded, it does it well. Please help, my headache is reaching the zenith. I am a newbie in Swift development, maybe I did something weird and stupid. I hope so :D Thank in advance!

Currently NaviagitonView on macOS creates a side panel. And then navigationViewStyle does not support stack view for macOS. Given this, is there currently a method to totally switch the content of a window from one view to another on macOS?

I have a class where I get data from firebase. But I can't get it exactly as I want, for example document("abc" ) here I need to get the name "abc" from another place, different name may come according to each click. I can't assign this to the class I'm getting the data from, can you help me? import Firebase struct StadiumNameView: View { var body: some View { VStack{ List(stadiumnameeeee) { i in NavigationLink(destination: SelectedStadiumView(selectedStadium:i.name)){ Text(i.name) } } } } } struct StadiumNameView_Previews: PreviewProvider { static var previews: some View { StadiumNameView() } } I need to pass the "i.name" here to the following class. import Firebase class UserInfoModel : ObservableObject { @Published var city="" @Published var email="" @Published var name="" @Published var surname="" @Published var phone="" @Published var town="" @Published var type="" @Published var id="" @Published var birthday="" @Published var favStadium=[String]() init(){ let db=Firestore.firestore() db.collection("Users").document(Auth.auth().currentUser!.uid).addSnapshotListener { (snapshot, error) in if error == nil { if let city=snapshot?.get("City") as?

I have 2 lists on different screens. It sorts the other list according to the data in the list I printed first. For example, if "name" is written in the list, it pulls data from firebase and lists it according to the "name" data in the other list.

Using SwiftUI's new Table container, how can I add a context menu that appears when Control-clicking a row? I can add the contextMenu modifier to the content of the TableColumn, but then I will have to add it to each individual column. And it only works above the specific text, not on the entire row: I tried adding the modifier to the TableColumn itself, but it shows a compile error: Value of type 'TableColumn<RowValue, Never, Text, Text>' has no member 'contextMenu' Here's what I have in terms of source code, with the contextMenu modifier in the content of the TableColumn: struct ContentView: View { @Environment(\.managedObjectContext) private var viewContext @FetchRequest(sortDescriptors: [NSSortDescriptor(keyPath: \Item.name, ascending: true)]) private var items: FetchedResults<Item> @State private var sortOrder = [KeyPathComparator(\Item.name)] @State private var selection = Set<Item.ID>() var body: some View { NavigationView { Table(items, selection: $selection, sortOrder: $items.sortDescriptors) { TableColumn("Column 1") { Text("Item at \($0.name!)") .contextMenu { Button(action: {}) { Text("Action 1") } Divider() Button(action: {}) { Text("Action 2") } Button(action: {}) { Text("Action 3") } } } TableColumn("Column 2") { Text($0.id.debugDescription) } } .toolbar { ToolbarItem { Button(action: addItem) { Label("Add Item", systemImage: "plus") } } } if selection.isEmpty { Text("Select an item") } else if selection.count == 1 { Text("Selected \(items.first(where: { $0.id == selection.first! })!.id.debugDescription)") } else { Text("Selected \(selection.count)") } } } } So, how can I add a context menu to the entire row inside the Table?

In my app, I need to have an onscreen button initiate a screenshot (which then gets saved to Photos, etc). Currently, every method I've tried from the forums (every version of UIGraphicsGetImageFromCurrentImageContext...) will capture everything EXCEPT the live feed from the camera, which is running as a sublayer on my view. Everything from labels to buttons and even background color shows up in the pictures using those methods but no matter what, the image from the camera is just a blank space on the pictures. However, when my app is running, I can press the two buttons and THAT picture always has the image from the camera included! I need this to happen with my onscreen button and that's what I just can't get to happen the same way. Does anyone know the actual function/extension/code that runs whenever someone presses the hardware buttons to initiate a screenshot? Or how to accomplish getting everything that's onscreen at a given time to be include in a screenshot, regardless of what layer(s) it's in?

Hi Team, We are developing an IoT project using Flutter. We have a requirement for our client. We have developed a mobile app that displays a list of nearby gateway wifi List. The user connects that Wifi and gets gateway information. Description: The app will scan for nearby SSIDs, the user can select any one of them, and the user can insert the password.  After successfully connecting, the user tries to connect to ssh client using host, port, username, password. Then the user used some commands to fetch HED/LED Logs information. Can you help me with how to archive it in IOS? Thanks, Sitakanta Sundaray

In the "What's new in Foundation" and "What's new in SwiftUI" talks there were examples of creating custom Attributed String styles. The example shown was for a rainbow style. They showed creating the style, serializing the style, using the style in a String - but did not show how to actually render the text in the rainbow style. How is that part done in SwiftUI. ie if I have Text("My fake example of ^[a custom style](customStyle: redAndEmphasized).") How would i create the piece that renders "a custom style" with foregroundColor red and a heavy font? Thanks, Daniel

Are there any relevant code examples to show how to use TableColumnBuilder and TableRowBuilder ？Thank you.

Using NSTableView in Cocoa framework, it is easy to implement drag and drop sorting of table headers (not row sorting). But I didn't find out how to use the Table component in SwiftUI.

I want to use the Table component to achieve the following functions Right click the column header to pop up context menu Right click each row to pop up context menu I found that TableColumn and TableRow objects are not of type view. Setting contextMenu is not supported. I can set the ContextMenu on the cell in the following ways, but it only works inside the cell, and clicking on the blank part does not take effect. TableColumn("Given Name", value: \.givenName) { person in Text(person.givenName) .contextMenu(menuItems: { Button { } label: { Text("New Order") } }) } How to set independent context menus on rows and column headers?
