On this page in Apple's website you'll find the phrase "iOS design language". The macOS design language for a long time was Aqua but since Mojave, Aqua is treated like a legacy term in the SDK.

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.
