I built and loaded the final folder for the QuadTree demo and it loads but touching the screen has no effect. Same with the starter with the code examples.
Tried with both Simulator and IPAD Pro.
iOS 14 (build target)
Xcode 13.4.1
Thanks for reporting the problem. On SwiftUI the iPad defaults to a main-detail style list navigation. To make it use the whole screen you need to add the modifier .navigationViewStyle(.stack).
You can open AppMain.swift and add it there:
@main
struct AppMain: App {
var body: some Scene {
WindowGroup {
ContentView().navigationViewStyle(.stack)
}
}
}
