No matter what I have tried, I can't get my test "What would you like to do?" to appear at the top of the screen. What have I missed? Is something g to do with the ZStack? import SwiftUI import SwiftData struct ContentView: View { @Environment(\.modelContext) private var context @Query private var readings: [Readings] @State private var readingTimeStamp: Date = Date() var body: some View { ZStack { Image("IPhone baqckgound 3") .resizable() .aspectRatio(contentMode: .fill) .padding(.top, 40) VStack { Text("What would you like to do?") .font(.title) .fontWeight(.bold) } .padding() Spacer() } } }

I am trying to develop an app that runs on iMacs, iPhones and iPads. so how, using SwiftUI, do I check what device I am running on?
