As far as I understand, the Simulator zooms the UI to whatever window size you want, which is great. However, is there a way to set/force the Simulator resolution to exactly the same (physical) resolution as the device skin? E.g. adjust the Simulator window to have the same number of pixels as an iPhoneX screen.
Check the Scrollable option in the Simulate menu of the simulator. It will add a scrollbar to the skin of the simulator and it should be in the same exact resolution without scaling.
