Here is the full error: `Fatal error: No ObservableObject of type LocationsViewModel found. A View.environmentObject(_:) for LocationsViewModel may be missing as an ancestor of this view.` I am essentially creating an app. The user can login/register. Once the user logs in they see a map view (MapKit). Here is just the main code (excluding the login/register parts). Any idea what i am doing wrong? // MARK: MAP SCREEN struct UserScreen: View {   @Binding var sucessLogin : Bool   @StateObject private var vm = LocationsViewModel()       var body: some View{     ZStack{       Map(coordinateRegion: $vm.mapRegion)         .ignoresSafeArea()               VStack(spacing: 0){         VStack{           Button(action: vm.toggleLocationsList){             Text(vm.mapLocation.name + ", " + vm.mapLocation.cityName)               .font(.title2)               .fontWeight(.black)               .foregroundColor(.white)               .frame(height: 55)               .frame(maxWidth: .infinity)               .background(Color("Theme"))               .overlay(alignment: .leading){                 Image(systemName: "arrow.down")                   .font(.headline)                   .foregroundColor(.white)                   .padding()               }           }           if vm.showLocationsList{             LocationsListView()           }         }         .background(.thickMaterial)         .cornerRadius(10)         .shadow(color: Color.black.opacity(0.3), radius: 20, x: 0, y: 15)         .padding()         Spacer()       }     }     .navigationTitle("")     .navigationBarHidden(true)     .navigationBarBackButtonHidden(true)   } } I then have a LocationsViewModel which is in a different SwiftUI View file because I have a custom dropdown menu, here is the code: // MARK: MAP Screen ViewModel class LocationsViewModel: ObservableObject{   @Published var locations: [Location]   @Published var mapLocation: Location{     didSet{       updateMapRegion(location: mapLocation)     }   }       //Show current region on map   @Published var mapRegion: MKCoordinateRegion = MKCoordinateRegion()   let mapSpan = MKCoordinateSpan(latitudeDelta: 0.1, longitudeDelta: 0.1)       // Show list of locations   @Published var showLocationsList: Bool = false       init(){     let locations = LocationsDataService.locations     self.locations = locations     self.mapLocation = locations.first!     self.updateMapRegion(location: locations.first!)   }       private func updateMapRegion(location: Location){     withAnimation(.easeInOut){       mapRegion = MKCoordinateRegion(         center: location.coordinates,         span: mapSpan)     }   }       func toggleLocationsList(){     withAnimation(.easeInOut){       showLocationsList.toggle()     }   } } Not sure what the error means and how I can fix it, because in my ViewModel i have it extended to Observable Object. If you would like I can also provide a GitHub link to my project.

I want to blur the button if the condition inside .disable(condition) is true. How can i do this in swiftui? For example. Button(action: {     // What to perform }) {     // How the button looks like } .disable(tnum < 100) at the same time if tnum count goes under 100, i want the button to be blured as well. how can i achieve this?

Lets say I have an array of numbers like this: // Create Array Of Numbers let numbers = ["1","2","3","4","5"] If I want to print a random number from the array, I can do something like: pickedNumber = Int.random(in: 0...numbers.count - 1) The above line will return a random value from my array. What I would like to do is, set a probability for each value in the array. For example: - Chance of 1 being picked at 10% - Chance of 2 being picked at 20% - Chance of 3 being picked at 30% - Chance of 4 being picked at 35% - Chance of 5 being picked at 5% What's the best approach for this? Any guidance or advice would be appreciated. This problem I am facing is in swiftUI.

I am creating a to-do list app. I need help or guidance in creating the following UITextInput and UITextView put it into some sort of container to get the rounded corners. I have tried to create it by implementing a UITableView, creating 2 cells. One with TextInput and one with TextView but it doesn't work, I have a feeling it's a wrong approach or there might be a better way to achieve this. Any guidance or help would be appreciated.
