Concept

TabView is used in SwiftUI to organize an app into multiple main sections using tabs.

It allows apps to:

switch between top-level screens
group major sections of the app
keep navigation simple and structured

Core flow:

TabView → Tab Items → Selected Tab Content

What It Does

TabView displays different views based on the currently selected tab.

It is commonly used for:

home screen sections
main app navigation
switching between independent areas

Each tab usually represents a major part of the app.

Basic Structure

TabView {
    HomeView()
        .tabItem {
            Label("Home", systemImage: "house")
        }

    ProfileView()
        .tabItem {
            Label("Profile", systemImage: "person")
        }
}

Here:

TabView → container for tabs
tabItem → label for each tab
HomeView / ProfileView → content for each tab

Tab Items

Each screen inside TabView uses .tabItem to define its tab button.
