I am redoing the tutorial, and have found issues with the code. In fact, I've had to change a few things. Is this due to different versions of Xcode? for example... the preview is specified in the tutorial as : #Preview { Group { LandmarkRow(landmark: landmarks[0]) LandmarkRow(landmark: landmarks[1]) } } When I create a new view, the preview is automatically provided as: struct LandmarkRow_Previews: PreviewProvider { static var previews: some View { LandmarkRow(landmark: landmarks[0]) } } Am I missing something, or is it another version of the code, and then certain things don't work anymore?
