Is it currently possible to use Bevy with given MTKView on iOS?

We have already an app with thousands lines of code and we need to render a game like experience on a just single page. We can achieve this with SpriteKit or SceneKit but we need something on android as well. So we are investigating a cross-platform tool.

The given iOS example on Github repository creates the window itself but it not possible for us.

edit: It looks like bevy uses winit for windowing and it doesn't support this. So winit is the blocker here.
