Overview 概要

To create a user interface with tabs, place views in a TabView and apply the tabItem(_:) modifier to the contents of each tab. On iOS, you can also use one of the badge modifiers, like badge(_:), to assign a badge to each of the tabs. The following creates a tab view with three tabs, the first of which has a badge:

TabView {
    Text("The First Tab")
        .badge(10)
        .tabItem {
            Image(systemName: "1.square.fill")
            Text("First")
        }
    Text("Another Tab")
        .tabItem {
            Image(systemName: "2.square.fill")
            Text("Second")
        }
    Text("The Last Tab")
        .tabItem {
            Image(systemName: "3.square.fill")
            Text("Third")
        }
}
.font(.headline)

Tab views only support tab items of type Text, Image, or an image followed by text. Passing any other type of view results in a visible but empty tab item. 何らかの他の型のビューを渡すことは、ある変数しかし空のタブ項目という結果になります。
