Full-screen sheets aren’t new (Apple started using them all the way back in iOS 13), which means that medium-size sheets are the real stars of the show here, and Apple is aware of this. Medium sheets are packed with options: developers can make them resizable; they can optionally add a grabber at the top of the sheet; they can even customize the corner radius to make sheets fit their app UIs better. Medium sheets support automatic keyboard avoidance (if the keyboard comes up, the sheet expands to fill the screen automatically – a nice transition), and developers can choose to enable a non-modal behavior that lets users interact with content within and beyond the sheet. On iPad, developers can choose to display a sheet as a popover, which becomes an iPhone-like sheet if an app is turned into a compact Split View or Slide Over.
