I was scratching my brains over something when this popped in my mind. Can we set the simulator\'s home-screen background image to an image of our choice? Case in point is Xcode
Dragged the image onto the simulator (iOS 9.3) as @boltclock suggests, but nothing happened. However, I then noticed that the images I dragged were showing up in the Photos app on the simulator. From there I just set the wallpapers the same way that you set them on a physical device. Did not need to restart the simulator.
