While I'm not entirely sure it's 100% analogous to Material Design, I'd say the term you're looking for is Human Interface Guidelines.

5 days ago - Aqua is a graphical user interface, design language and visual theme used in Apple Inc.'s operating systems.

r/UXDesign on Reddit: Does anyone use a corporate design system with both Apple HIG and Material UI?
October 5, 2024 -

I’ve used design systems that were based on Material and used on web and all mobile apps. I’m hearing that using Apple’s HIG components is a better solution for iOS apps for both users and developers. However, it seems like you’d be limited in how much you can customize fonts, colors, etc. Plus it seems like every time you want to update something, you have to manage two component libraries.

Is this the recommended way of building out components? Upsides/downsides? Thanks.
