How to embed views in a tab bar using TabView
Fully updated for Xcode 11.1
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) {SAVE 20% ON iOS CONF SG The largest iOS conference in Southeast Asia is back in Singapore for the 5th time in January 2020, now with two days of workshops plus two days of talks on SwiftUI, Combine, GraphQL, and more!
