iOS wgpu+winit build process

[archee565]

I need to be able to handle in-app purchases and admob ads from Objective-C or Swift parts in an App Store game made in Rust, so the pure Rust approach probably won't work.

Anybody can help setting up an Xcode project, which builds for iOS devices?

I'm getting debug messages from my wgpu based app, but I can't see anything displayed. Maybe the main storyboard is covering the winit+wgpu window.

Do I need a storyboard at all?
Do I need to create something like a Metalview?
Do I need to create a separate thread for the Rust main?

Update:
I was able to figure it out based on the description in uikit/lib.rs
However redraw_request-s seem to be ignored on iOS, so there is no animation.
It might be necessary to avoid using the run_app and application handler approach.
