By default, device previews appear right side up, using orientation portrait. You can change the orientation of a preview using one of the values in the InterfaceOrientation structure:


struct CircleImage_Previews: PreviewProvider {
    static var previews: some View {
        CircleImage()
            .previewInterfaceOrientation(.landscapeRight)
    }
}
