Hi I am a beginner and I am preparing to make a Tabbar component for use in my practice APP. The component uses Image as the button. When the button is clicked (onTapGesture), I hope that the color in the IMAGE will change, but now When running to onTapGesture, XCode crashes, who knows how to write this code to make it run normally. Thanks class MainViewManager : ObservableObject{ @Published var tabbarStatus : TabbarStatus = .homeView enum TabbarStatus : CaseIterable { case homeView case articsPage case profile var icon : String{ switch self{ case .homeView: return "house" case .articsPage: return "person.2" case .profile: return "person.crop.circle" } } } } struct MainTabbar: View { @EnvironmentObject var vm : MainViewManager @State var btnColor : Color = .gray var body: some View { HStack{ ForEach(MainViewManager.TabbarStatus.allCases, id: \.self) { tabbarItem in //let selected = tabbarItem == vm.tabbarStatus Image(systemName:tabbarItem.icon) .foregroundStyle(btnColor) .onTapGesture { vm.tabbarStatus = tabbarItem btnColor = Color.accentColor } if tabbarItem != .profile { Spacer() } } } .padding(.horizontal,30) .padding(.all) .frame(maxHeight: .infinity ,alignment: .bottom) .background(Color.white) } } #Preview { MainTabbar() }
