App size question

So I read I can have larger size apps using expansion files for android but how do I do it for IOS?
I read it can be up to 4gb but then it says keeping in mind that there is a 100 MB limit for over-the-air downloads.

So idk what to make of this?

Your app can be up to 4gb but it should be less than 100mb if you want people to be able to download over cellular network.

Ahh ok that makes sense then. I think they raised it to 150 actually.

Yeah, I think you’re right.
