Since I downloaded the Xcode beta version, a strange process has occurred with the views with my navigation. I couldn’t find anything online about this, I’ve also searched for transitions and animations in my code, but unfortunately I couldn’t find anything.

I hope you can help me further.

Here is my navigation contentview code:

import SwiftUI

struct ContentView: View {
    @State private var selectedTab: Tab = .house
    
    init() {
        UITabBar.appearance().isHidden = true
    }
    
    @State var isFullView:Bool = false
    @State private var showSignInView: Bool = false
    @StateObject private var designSelection = Design_selection()
    
    var body: some View {
        ZStack {
            VStack(spacing: 0) {
                if !showSignInView {
                    TabView(selection: $selectedTab) {
                        dashboard_iphone_view(profilViewModel: ProfilViewModel())
                            .toolbar(.hidden, for: .tabBar)
                            .toolbarBackground(.hidden, for: .tabBar)
                            .environmentObject(designSelection)
                            .tag(Tab.house)
                        
                        todo_iphone_view(profilViewModel: ProfilViewModel(), design_selection: Design_selection())
                            .toolbar(.hidden, for: .tabBar)
                            .toolbarBackground(.hidden, for: .tabBar)
                            .tag(Tab.list)
                        
                        pomodoro_timer_iphone(isFullView: $isFullView, profilViewModel: ProfilViewModel(), design_selection: Design_selection())
                            .toolbar(.hidden, for: .tabBar)
                            .toolbarBackground(.hidden, for: .tabBar)
                            .tag(Tab.clock)
                        
                        CalendarView(profilViewModel: ProfilViewModel())
                            .toolbar(.hidden, for: .tabBar)
                            .toolbarBackground(.hidden, for: .tabBar)
                            .tag(Tab.calendar)
                        
                        habit_main(profilViewModel: ProfilViewModel(), design_selection: Design_selection())
                            .toolbar(.hidden, for: .tabBar)
                            .toolbarBackground(.hidden, for: .tabBar)
                            .tag(Tab.habit)
                    }
                }
            }
            
            if isFullView == false{
                VStack {
                    Spacer()
                    CustomTabBar(selectedTab: $selectedTab)
                }
            }
        }
        .edgesIgnoringSafeArea(.bottom)
        .statusBarHidden(isFullView)
    }
}

#Preview {
    ContentView()
}

And this is my CustomTabBar:

import SwiftUI

enum Tab: String, CaseIterable {
    case house = "house"
    case list = "list.bullet.clipboard"
    case clock = "clock"
    case calendar = "calendar"
    case habit = "water.waves"
}

struct CustomTabBar: View {
    @Binding var selectedTab: Tab

    private var fillImage: String {
        selectedTab.rawValue
    }

    private var tabColor: Color {
        return Color(.white)
    }

    var body: some View {
        VStack {
            HStack {
                ForEach(Tab.allCases, id: .rawValue) { tab in
                    Spacer()
                    VStack(spacing: 4) {
                        Image(systemName: tab.rawValue)
                            .scaleEffect(selectedTab == tab ? 1.2 : 1.0)
                            .foregroundColor(selectedTab == tab ? tabColor : Color(.white))
                            .font(.title3)
                            .onTapGesture {
                                withAnimation(.easeInOut(duration: 0.2)) {
                                    selectedTab = tab
                                }
                            }
                        if selectedTab == tab {
                            Circle()
                                .fill(Color.white)
                                .frame(width: 5, height: 5)
                        }
                        
                        HStack{
                            
                        }
                        .frame(height: 10)
                    }
                    Spacer()
                }
            }
        }
        .frame(height: 80)
        .background(.thinMaterial)
        .clipShape(
            .rect(
                topLeadingRadius: 40,
                bottomLeadingRadius: 0,
                bottomTrailingRadius: 0,
                topTrailingRadius: 40
            )
        )

    }
}

struct CustomTabBar_Previews: PreviewProvider {
    static var previews: some View {
        CustomTabBar(selectedTab: .constant(.house))
    }
}
