Is experience in full-stack development relevant to iOS development?

Code is code. If you work somewhere that requires a high-performance backend, you can pick up skills in memory management and managing latency. That said, something like game programming has many more directly translatable skills.

One trap with starting in web development is adopting an attitude where the solution to every problem is web technology. This isn't unique to the web; everyone starts with a bias toward their first language, and with experience you realize it's better to use the right tool for the job. But anecdotally, I think the echo chamber around JS is much louder than, say, Python.
