Hi all, I need help sending a 1/0 signal from iPad/macbook to iPad/macbook via wifi using SwiftUI. This does not require any memory, just sending a 1/0 signal. I am trying to do smth similar to embedded system. On Macbook Swift UI app, when I click the button "Go". It will send a signal via wifi to the Ipad which is also in the swift UI app, to change its display. The Macbook functions like a controller, when press 'On' on the UI, it will turn on the display on iPad UI. Cant find any example online regarding this problem. Thank you! MacBook 0 ->0 -> 0 iPad Display unchanged MacBook 1 -> 1 -> 1 iPad Display Changed when receives a signal from Macbook Via Wifi.

I need help communicating between 2 ios app. I want to send a signal from Macbook to Ipad via Wifi using SwiftUI. When I press a Button on MacBook SwiftUI, iPad SwiftUI app will receive the signal and changes the display from red to black. I could not find any example online.

Hi, I want to import swift packages from GitHub, but my xcode 13.1 do not have the 'swift packages' under the file list as shown an example I watched online. My Xcode file list only have 'packages' instead of 'swift packages'. Please assist! Thank you!

My Xcode does not seem to recognise the socket.io package uploaded from github. The socket.io package I see on youtube examples have the sub files arrow and different file title from mine. I did the exact same but the uploading seems to be incorrect. Example: https://github.com/socketio/socket.io-client-swift On my Xcode: Is there any other function out there other than socket.io for iOS (Swift) to Android to communicate via wifi/IP Address? Thank you

Hi all, Im doing a API using socket.io. I want to store one of the line from final class into my button action which is " socket.emit("Server Port","Hi server111")". When i declare the " socket.emit("Server Port","Hi server111")". The code is working and will send the msg when connected to server. What I am trying to do is to do a continuous send to server after connected which I am stuck at. My last line of code have an error Value of type '(Int32, Int32, Int32) -> Int32' has no member 'emit' Thank you for reading. final class Service: ObservableObject {   private var manager = SocketManager(socketURL: URL(string:"ws://localhost:4005")!, config:[.log(true), .compress])           init(){     let socket = manager.defaultSocket      socket.on(clientEvent: .connect){ (data, ack) in //connect and send/emit       print("Connected")       DispatchQueue.main.async{         socket.emit("Server Port","Hi server111")       }}     struct ContentView: View {   var body: some View {    @ObservedObject var service = Service()     VStack{       Text("Received messages from Node.js")         .font(.largeTitle)               TextField("Type Smth:", text: $test)       Text("Output: \(test)")                   Button("Save", action:{         socket.emit("Server Port","Hi server111") // <<--

0 I am trying to implement input textfield for user to enter 'longitude' and 'latitude' to make annotation on the map. The scenario I want to achieve: When user click 'save' button after filling in both longitude and latitude. The annotation will appear based on the latitude and longitude inputs. I got 2 strings, "savedLong" and "savedLat". Please advice me if Im on the right track to solving my issue. Thank you! I get errors when I replace the Longitude and Latitude values with 'savedLong' and 'savedLat', example below is a portion of my current progress, MyAnnotationItem( coordinate: CLLocationCoordinate2D( latitude: savedLat, //instead of numbers that is able to work longitude: savedLong), //instead of numbers that is able to work color: .green)] Code below will save user input for both Latitude and Longitude, VStack{ TextField("Latitude", text: $textFieldLat) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() .background(Color.gray.opacity(0.3).cornerRadius(10)) .foregroundColor(.red) .font(.headline) TextField("Longitude", text: $textFieldLong) .textFieldStyle(RoundedBorderTextFieldStyle()) .padding() .background(Color.gray.opacity(0.3).cornerRadius(10)) .foregroundColor(.red) .font(.headline) Button(action: { savedLat = textFieldLat ////<-- saved as latitude to plot savedLong = textFieldLong////<--- saved as longitude to plot }, label: { Text("Save".uppercased()) .padding() .background(Color.gray.opacity(0.3).cornerRadius(10)) .foregroundColor(.red) .font(.headline) }) Text("Lat: "+savedLat+" Long: "+savedLong) Code below is my current progress and is able to run. import MapKit import SwiftUI struct ContentView: View { @StateObject private var viewModel = ContentViewModel() struct AnnotatedItem: Identifiable { let id = UUID() var name: String var coordinate: CLLocationCoordinate2D } private var pointsOfInterest = [ //annotate on map AnnotatedItem(name: "Location A", coordinate: .init(latitude: 5.76123, longitude: 156.52318)) ] var body: some View { Map(coordinateRegion: $viewModel.region, showsUserLocation: true, annotationItems: pointsOfInterest){ item in MapMarker(coordinate: item.coordinate) } .ignoresSafeArea() //full screen .accentColor(Color(.systemPink)) //color of icon .onAppear { viewModel.checkIfLocationServicesIsEnabled() } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } enum MapDetails { static let startingLocation = CLLocationCoordinate2D(latitude: 5.76123, longitude: 156.52318) static let defaultSpan = MKCoordinateSpan(latitudeDelta: 0.1, longitudeDelta: 0.1) } final class ContentViewModel: NSObject, ObservableObject, CLLocationManagerDelegate { @Published var region = MKCoordinateRegion(center: MapDetails.startingLocation, span: MapDetails.defaultSpan) var locationManager: CLLocationManager? func checkIfLocationServicesIsEnabled(){ if CLLocationManager.locationServicesEnabled(){ locationManager = CLLocationManager() locationManager!.delegate = self }else{ print("Show map is off") } } private func checkLocationAuthorization(){ guard let locationManager = locationManager else {return} switch locationManager.authorizationStatus{ case .notDetermined: locationManager.requestWhenInUseAuthorization() case .restricted: print("Location restricted") case .denied: print("Location denied") case .authorizedAlways, .authorizedWhenInUse: region = MKCoordinateRegion(center: locationManager.location!.coordinate, span: MapDetails.defaultSpan) break @unknown default: break } } func locationManagerDidChangeAuthorization(_ manager: CLLocationManager) { checkLocationAuthorization() } } }

Hi I am trying to annotate on map after displaying the map. I am able to take in lat and long from user and convert it to Double. But stuck at the annotate on the map part. I am able to annotate hard coded values but I do not know how to convert it to annotate using user`s input of lat and long. I struggling to include the init( ...) part into my identifiable portion. I cant seem to get it right. I found this link from apple but it doesnt work. https://developer.apple.com/documentation/mapkit/mapmarker#see-also import MapKit import SwiftUI struct IdentifiablePlace: Identifiable { let id: UUID let location: CLLocationCoordinate2D init(id: UUID = UUID(), lat: Double, long: Double) { self.id = id self.location = CLLocationCoordinate2D( latitude: lat, longitude: long) } } struct PinAnnotationMapView: View { let place: IdentifiablePlace @State var region: MKCoordinateRegion var body: some View { Map(coordinateRegion: $region, annotationItems: [place]) { place in MapMarker(coordinate: place.location, tint: Color.purple) } } } Thanks
