Your parent is clearly answering the OP’s second question but not the first, come on. I’m aware of production iOS apps using Rust that are either: 1. Using rust for core logic but still using Swift/obj c for UI. 2. Pure Rust but don’t use native widgets. Like games or similar custom UI. That said it is in my understanding theoretically possible but I’m not aware of a paved cow path here. It’s also not my area of specialty though.
