To create a navigation bar in SwiftUI, you can use the NavigationView and NavigationStack components. Here is a basic example of how to set up a navigation bar:
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView {
VStack {
Text("Hello, World!")
}
.navigationTitle("Home")
.navigationBarItems(trailing: Button(action: {
print("Button tapped")
}) {
Image(systemName: "plus")
})
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
In this example:
NavigationViewis used to create a navigation context.navigationTitlesets the title of the navigation bar.navigationBarItemsallows you to add items to the navigation bar, such as buttons.
