Publishing an app from Swift Playgrounds 4.1

I have successfully made an iOS app with Swift Playgrounds 4.1 (without Xcode). Now I'm ready to publish it. However, publishing the app requires screenshots from 4 different devices. How do I obtain those screenshots without Xcode and without owning those 4 devices? Any suggestions?

...ask others to do it for you? and... 4.1???

In macOS I tried "Share Simulator" but 1) it doesn't start a simulator; so 2) I used Xcode to start the simulator; then "Share Simulator" just copies the .pm. Shouldn't it install as an app in the Simulator? Finally opened .pm in Xcode and got the app into the simulators: taking all necessary screenshots that way. So, not completely without Xcode.
