Step-by-Step Solution
Solution:
Step 1: Check tabItem syntax for each tab
TabView { HomeView().tabItem { Label("Home", systemImage: "house") } SearchView().tabItem { Label("Search", systemImage: "magnifyingglass") } ProfileView().tabItem { Label("Profile", systemImage: "person") } } correctly uses braces with Label including both text and systemImage for each tab.Step 2: Review other options for errors
TabView { HomeView().tabItem(Label("Home", systemImage: "house")) SearchView().tabItem(Label("Search", systemImage: "magnifyingglass")) ProfileView().tabItem(Label("Profile", systemImage: "person")) } misses braces, causing syntax errors. TabView { HomeView().tabItem { Text("Home") } SearchView().tabItem { Text("Search") } ProfileView().tabItem { Text("Profile") } } uses Text instead of Label, so no icons. TabView { HomeView().tabItem { Label("Home") } SearchView().tabItem { Label("Search") } ProfileView().tabItem { Label("Profile") } } uses Label without systemImage, so no icons.Final Answer:
TabView { HomeView().tabItem { Label("Home", systemImage: "house") } SearchView().tabItem { Label("Search", systemImage: "magnifyingglass") } ProfileView().tabItem { Label("Profile", systemImage: "person") } } -> Option CQuick Check:
