Textfield tap is dismissing navigation link in SwiftUI

Question

I'm facing a weird issue with textfields and navigation view/link using SwiftUI

All I do is navigate through views using navigation links and inside the destination view there are some textfields. When I tap on any of them the navigation automatically dismisses.

How can I fix navigation link from dismissing when textfield is tapped on and the keyboard shows up?

var emailLoginButton: some View {
    NavigationLink(destination: LoginView(viewModel: .init(mode: .login, isPushed: $viewModel.authViewPushed)), isActive: $viewModel.authViewPushed) {
        Button(action: { viewModel.authViewPushed = true }) {
            HStack {
                Image(systemName: "envelope")
                    .resizable()
                    .aspectRatio(contentMode: .fit)
                    .frame(width: 20, height: 20)
                    .foregroundColor(.white)
                
                Text("continue_with_email".localized())
                    .padding(.horizontal, 20)
            }
        }
        .padding()
        .frame(maxWidth: .infinity)
        .foregroundColor(.white)
        .background(Capsule().fill(Color.primaryPurple))
        .shadow(color: Color.black.opacity(0.15), radius: 5, x: 5, y: 5)
        .padding(.horizontal)
        .padding(.bottom, 20)
    }
    .isDetailLink(false)
}

// Destination's view textfield which "dismisses" navigationLink
var emailTextField: some View {
    HStack {
        Image(systemName: "envelope")
            .font(.title2)
            .foregroundColor(.primary)
            .frame(width: 35)

        TextField(viewModel.emailPlaceholderText.uppercased(), text: $viewModel.email)
            .autocapitalization(.none)
    }
    .padding()
    .background(Color.white.opacity(viewModel.email == stringEmpty ? 0 : 0.12))
    .cornerRadius(12)
    .padding(.horizontal)
}

Answer 1

After some time of research I've found that NavigationLink closes because authViewPushed parameter in the viewModel becomes false. That happens because viewModel is being recreated because of firstView update. I've faced the same issue and here is the solution:

struct MyView: View {
    @StateObject var viewModel = MyViewModel()

    var body : some View {
        
    }
}

In this case MyView is being updated but MyViewModel remains the same.
