>But…you can? I have a UI test that generates screenshots in the simulator and I upload those. It complained about the alpha channel, and I needed to open (in GIMP) all of the screenshots created by the Xcode simulator in order to strip it out.

  You're incredibly lucky then :) There are multiple posts on Reddit, StackOverflow and Apple's own product support site about this: https://www.reddit.com/r/iOSProgramming/comments/9fd7qu/taking_screenshots_in_the_simulator_for_app_store/ https://www.reddit.com/r/iOSProgramming/comments/9fd7qu/taki... https://forums.developer.apple.com/thread/108462 https://forums.developer.apple.com/thread/108462 https://stackoverflow.com/a/54653683/5056459 https://stackoverflow.com/a/54653683/5056459

    Those users have enabled options that add "cutouts" to the images. By default the simulator will take rectangular screenshots.

      I've not changed the settings at all - and that's the sort of screenshots that the simulator generates for me (for e.g. the iPhone X).
