I don't know how it works, is that the reason it's so slow?

around 30k lines of code I'd say, I only had minor problems due to screen sizes but that's pretty much the same everywhere.

Why do I have a feeling that you aren’t that experienced with iOS or mobile? You are running into problems that most iOS developers don’t run into and you’re not having to experience supporting a fragmented Android ecosystem that most developers have to go through with complicated apps

I've also used iOS for about a year and it was hands down the worst mobile experience I ever had. I don't criticize here though, it's a matter of personal taste unlike the dev experience.

Those problems are real and you have tons of threads online. The thing is, the iOS dev stack looks brittle, you're unlikely to have the different problems as somebody else and there's no way to debug it anyways.
