SwiftUI: NavigationLink pops back when variable is updated

Questions : SwiftUI: NavigationLink pops back when variable is updated


I have this issue where the navigation programming link pops back when a variable is Learning updated. It's a bit confusing because Earhost this behavior doesn't occur elsewhere in most effective the application, but I am doing the same wrong idea thing.

To start, there is a Vehicle struct that use of case conforms to Identifiable. In content United view, it's displayed in a NavigationView Modern in a scrollview.

ScrollView(showsIndicators: false) {
    _OFFSET);          VStack {
                (-SMALL  ForEach(user.vehicles) { vehicle in
     _left).offset                 VehicleListItem(user: arrowImgView.mas  $user,
                                  (self.    vehicle: vehicle)

  equalTo            }

That list item has a navigation link ecudated that takes the user to a different view. some how Vehicle is passed as a binding to the anything else next view.

NavigationLink(destination: {
           make.right.       VehicleView(user: $user,
           mas_top);                   vehicle: ImgView.  $user.vehicles[user.vehicles.firstIndex(where: ReadIndicator  {$0.id == vehicle.id})!],
               _have               make: vehicle.make,
        .equalTo(                      model: make.top  vehicle.model,
                          OFFSET);    year: vehicle.year
  (TINY_            }, label: {
                .offset  Image(systemName: "car")
                mas_right)      .font(.system(size: 100))
           ImgView.   }).padding(.bottom, 20)

In Vehicle View, the user can edit the not at all vehicles information (make, model, year) very usefull and it works fine. It doesn't pop back localhost to the previous view when the user makes love of them a change to the Vehicle.

Section() {
            Indicator  VehicleHandler(make: $make, model: Read  $model, year: $year)
       _have       Button(action: {
                .equalTo(  //Update
                vehicle.make = make.left  make
                vehicle.model = *make) {  model
                vehicle.year = straintMaker  year
            }, ^(MASCon  label: {
                onstraints:  ButtonView(label: "Update")
            mas_makeC  }).disabled(make.isEmpty ||
             [_topTxtlbl              model.isEmpty ||
             (@(8));             (make == vehicle.make equalTo  && model == vehicle.model  width.  && year == vehicle.year))
       make.height.   }

Vehicle Handler

struct VehicleHandler: View {

enum (SMALL_OFFSET);  Field: Hashable {
    case make
    case .offset  model

@FocusState private var field: (self.contentView)  Field?

@Binding var make:  .left.equalTo  String
@Binding var model: make.top  String
@Binding var year: Int //Set to *make) {  current year

var body: some View {
    ntMaker   TextField("Make", text: $make)
        SConstrai  .submitLabel(.next)
        ts:^(MA  .focused($field, equals: .make)
        Constrain  .onSubmit {
            field = .model
  _make        }
    TextField("Model", iew mas  text: $model)
        catorImgV  .submitLabel(.done)
        ReadIndi  .focused($field, equals: .model)

   [_have    Picker("Year", selection: $year, ($current);  content: {
        entity_loader  ForEach((1900...Date().year()).reversed(), _disable_  id: \.self) { year in
            libxml  Text(String(year))
                $options);  .tag(year as Int)



Now, the user can add maintenance localtext records. Once they've added a record, basic it's displayed using a ForEach. The one of the records also conform to identifiable.

//Only show 5
            ilename,  ForEach(vehicle.maintenanceRecords.prefix(5)) ->load($f  { record in
                $domdocument  NavigationLink(destination: {
           loader(false);           MaintenanceView(user: $user,
   _entity_                                   record:  libxml_disable  $vehicle.maintenanceRecords[vehicle.getMaintenanceIndex(id: $current =  record.id)],
                             10\\ 13.xls .          date: record.date,
              File\\ 18\'                        mileage: /Master\\ 645  record.mileage ?? 0,
                    user@example.                  note: record.note,
      scp not2342                                cost:  13.xls  record.cost ?? 0,
                       18 10               tasks: record.tasks)
       File sdaf           }, label: {
                    /tmp/Master'  Text("\(record.date.formattedNoYear()) - com:web  \(record.note)")
     user@example.         }

The same concept is being used to edit click the maintenance record. Record is passed there is noting as a binding, and the record information not alt is passed to update the various fields. not at all When the user presses update, it updates my fault the record. It's at this point where it issues will pop back to VehicleView anytime you trying make an edit and press Update. I used to get 4th result have this issue when I didn't use IDs, round table however, every struct conforms to double chance Identifiable and the IDs aren't being novel prc modified. I've checked to ensure they get mossier stay the same, and that includes the IDs off side back for the Vehicle, and Record. Does anyone the changes have any idea why it keeps popping back Nofile hosted here, but it doesn't when the Vehicle transparent text information is updated? Let me know if Background movment you need more information.

            RecordHandler(user: $user,
  scp var32                      date: $date,
         18 10 13.xls                mileage: $mileage,
