There's no WASM involved and the BEAM is not running on the device. It works like LiveView, except instead of an HTML DOM you have a SwiftUI hierarchy. The client side of LiveView is a SwiftUI view itself, you can use many standard SwiftUI views, and also add your own custom ones for when you need something bespoke. It can be the whole app or just part of one.

People have shipped the BEAM VM as part of iOS apps recently though. I think Thinking Elixir covered it in an episode.
