hi folks! I'm new to swift but started a project with my son. we want to run this little code for converting GK4 coordinates into latitude longitude, store them in a listing and show them by click in Apple Maps. we've import a gausskrueger repository to our project folder. that's working surprisedly:) we've got some output in simulator and apple map open but sadly its showing 0.00000 N, 0.00000 and for sure the coordinates are in the blue ocean. can someone have a look? import SwiftUI import MapKit import GaussKrueger struct CoordinateConverterView: View {     @State private var xInput = ""     @State private var yInput = ""     @State private var coordinates: [String] = []          var body: some View {         VStack {             HStack {                 TextField("X", text: $xInput)                 TextField("Y", text: $yInput)             }             Button("Convert") {                 if let x = Double(xInput), let y = Double(yInput) {                     let coord = GKCoordinate(x: x, y: y).asWGS                     let coordinateString = "Latitude: (String(describing: coord?.latitude)) Longitude: (String(describing: coord?.longitude))"                     coordinates.append(coordinateString)                     xInput = ""                     yInput = ""                 }             }             List(coordinates, id: .self) { coordinate in                 HStack {                     Text(coordinate)                         .font(.system(size: 10))                     Spacer()                     Button(action: {                         self.showInMaps(coordinate: coordinate)                     }, label: {                         Image(systemName: "mappin.and.ellipse")                     })                 }             }         }     }          func showInMaps(coordinate: String) {         let scanner = Scanner(string: coordinate)         var latitude: Double = 0         var longitude: Double = 0         scanner.scanString("Latitude: ", into: nil)         scanner.scanDouble(&latitude)         scanner.scanString(", Longitude: ", into: nil)         scanner.scanDouble(&longitude)                  let coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)         let mapItem = MKMapItem(placemark: MKPlacemark(coordinate: coordinate, addressDictionary: nil))         mapItem.openInMaps(launchOptions: nil)     } }
