How to embed views in a tab bar using TabView
Updated for Xcode 12.0
SwiftUI’s TabView provides an equivalent to UITabBarController, allowing us to let the user switch between several active views using a bar at the bottom of the screen.
In its basic form, you should provide each item with an image and title, optionally also adding a tag if you want to control which tab is active programmatically. For example, this creates two views with different images, titles, and tags:
struct ContentView: View {
var body: some View {
TabView {
Text("First View")
.tabItem {
Image(systemName: "1.circle")
Text("First")
}.tag(0)
Text("Second View")
.tabItem {
Image(systemName: "2.circle")
Text("Second")
}.tag(1)
}
}
} If you add tags, you can programmatically control the active tab by modifying the tab view’s selection. First, add some state that can track the active tab:
@State var selectedView = 1Now pass that in to the TabView, like this:
TabView(selection: $selectedView) {
