    Project mention: Is it possible to write plain C iOS app in 2025? | news.ycombinator.com | 2025-04-14

    I’ve written a pure C Mac desktop app in 2024 that called the objective-c bindings directly. It is using a modified version of this library https://github.com/ColleagueRiley/RGFW

    While I don’t think that library does iOS specifically, you can have a look at the code to see how you can call objective-c from c. Spoiler: doing so kind of sucks, and also the library code isn’t the most elegant thing I’ve seen.
