Preview not changing device to iPhone SE when using SwiftUI

I am new to SwiftUI and I was trying to change my preview device to iPhone SE but the device does not change. When I update the text "Hello, world!" to something else in the ContentView, it does show the updated text on the preview device. The device is current the default device provided when I created a new project using SwiftUI. I am currently using Xcode version 12.0.1 and below is my code:

import SwiftUI

struct ContentView: View {
    var body: some View {
        Text("Hello, world!")
            .padding()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
            .previewDevice(PreviewDevice(rawValue: "iPhone SE"))
        
    }
}
Solution

  • You need to specify full designated name, like below (because there is 1st generation also)

    ContentView().previewDevice("iPhone SE (2nd generation)")

    the full list can be viewed in in Terminal as

    $ xcrun simctl list devicetypes
