While trying to capture a screenshot on Xcode V12.0.1 - the app screen turns to "Home screen" (of IOS) and a screenshot on the home screen is prodcued instead of the app screen.
It was working fine a week before, but my OS and Xcode were auto updated last week to MacOS 10.15.7 and Xcode V12.0.1 and since then i am unable to take screenshots of the simulator.
I ran into this issue and as of now I can only provide a work arround - Use command line to take the screenshot
xcrun simctl io booted screenshot Screenshot.pngFirstly, this problem still happens (at least, for me) in Feb 2021 with Xcode 12.3.
Secondly, I was running Xcode and the simulator on an older (slow) Mac mini, so doing something like xcrun simctl io booted screenshot Screenshot.png worked for me too, but it took over 30 seconds from pressing "enter" to when the snapshot was captured, so by then the simulator screen had changed (I was trying to get a screenshot of the launch image). I suppose with careful timing, to use the command 30 seconds or so before the time the simulator is displaying the desired screen, is one way, but tricky and error prone.
Thirdly, I tried restarting Xcode, after quitting the simulator as well, and it worked for me. It seems to have a good chance of working when Xcode is first started, although later the "home screen" bug appears to surface for some unknown reason.
If you copy the screen it seems to work as well.
Simulator -> Edit -> Copy Screen
Then paste the image from clipboard into an image editor etc.
