React native is an obstacle compared to what clear Swift/Kotlin code may produce. Swift is very powerful and Kotlin, in all honesty, is the first reasonable and very useful thing to come to the JRE ecosystem (save for Scala, which is, well, quite complex still).

Myself turned some python code to Swift, and keep doing so, without trouble or pressure. Of course, I've been doing fair amount of systems programming for 20 years now, so not sure what to advice newcomers. But this approach to dev DOES work for me very well.

Sounds like the advice to newcomers is to not worry about trying to learn a programming language. There already is an llm to program for you, and do it better than you could, so just learn how to talk.
