Swift MVVM based animated screen

Need specific layout to arrange users on the screen for a gaming app. There can be one or upto six players on the screen. One player will be the host in a central position, and rest can be added or removed. The adding and removing of players should be smoothly animated. This is to be built in Swift MVVM pattern, using view<->view Model interactions. The transitions should be as slow fly-in and fly-out animations (to be shared seperately)
