Вы можете предоставить устройства по их имени для предварительного просмотра нескольких устройств одновременно. Например, для предварительного просмотра «iPhone SE» и «iPhone XS Max» вы можете сделать следующее:
#if DEBUG
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ForEach(["iPhone SE", "iPhone XS Max"].identified(by: \.self)) { deviceName in
ContentView()
.previewDevice(PreviewDevice(rawValue: deviceName))
.previewDisplayName(deviceName)
}
}
}
#endif
