So I've noticed this type of view appearing across a variety of popular apps recently, including Music (iOS), Google Maps, and recently also Twitter:
It extends only partially from the bottom of the screen over the current view and can be swiped up to reveal more of it, or swiped down to dismiss it.
The notch at the top also seems to be a standard element for such views and can be dragged up or down to gradually show or hide the view rather than just strictly performing a swipe gesture.
Google hasn't been much help, so I was hoping someone here might be able to help me answer these questions:
- What is this type of view called? Does it have a name in the UI/UX lexicon?
- Is there some reason these views are suddenly so commonplace? (Or are they only common in iOS apps?)
Here's another example from the Google Maps app, with the leftmost screenshot being the default, starting state for the view and the rightmost being the fully exposed state that occurs after grabbing the notch and dragging or swiping the view up:
