Unfortunately when it comes to technology licensing, it is rarely successful to say you should pay less because you purposely made your job harder.
I don't intend to insult you, but as an iOS developer myself I have serious doubts about whether you have any expertise in the subject you're talking about here.
That's not really the issue. LLM participation is a red herring. The issue is "replicates the original's functionality".
It's you who has started to argue by replying to my comment in the first place.
Your answer seemed nonsensical to me.
What I meant, though, is that I'm not going to argue about a specific point, the viability of "some FOSS SDK that perfectly replicates the original's functionality." If you don't even have any experience with iOS development, then you have no basis for making any claims about that subject, and thus I'm not going to bother explaining "What would be so outlandish about that?"
In any case, most iOS devs don't want to opt out of using the SDK. That would not be a particularly attractive route for making iOS apps. What I want as an iOS dev is the same freedom of software distribution that we have on macOS.
The basis for my claims about the subject is my knowledge of computing and development in general. I dipped my toes into iOS dev a few times and there's nothing that seemed to set it apart from any other SDK situation beyond Apple's restrictions, at least nothing that would make my claim outlandish.
Core device apis yes, everything else, maybe not?
I think we could roll our own UI - I think we can roll our own payment systems - I think we could roll our own media display.
For the primary iOS app I work on I need vulkan, gps, touches camera, sound, and phone rotation. (And standard os services)
I don’t need anything else.
