Can't decide: Web development or iOS development

I've worked in AV for 7 years professionally,I decided to learn little programming in my free time. Last january I started learning Python and it sort of became my new hobby. Right now I understand programming principles and I can code but I still lack a lot of general knowledge. Also I've never done anything professionally nor had my code reviewed. But I found out I really enjoy doing this and I'd like to turn it into a career. Right now my motivations aren't financial (at least not as much). I value more to have some kind of job stability instead of earning more. I finally decided that I really want to do something that I like. Also, in my previous job, the industry has shifted and my occupation became de-valued and employment is not a sure thing anymore.

Ironhack offers both web development and iOS courses. I can't decide which one to take. Here are my thoughts:

1. Web dev

+ it is something I am already familiar with (web design)

+ I can already build sites with HTML, CSS and various tools (WP, static website generators etc.)

+ from previous job I have lot of graphic experience

+ I can already do some web development stuff with Python - managed to do little Flask app

- I'm afraid that there are way too much full-stack devs out there and it's gonna bring the market down (I don't wanna end up in situation where I'm at now)

- I'm still not quite sure what web developer does 100%, aren't you some sort of jack-of-all-trades kind of dev? Maybe it's too "unspecialized"

2. iOS

+ I'm quite interested to program on hardware device + fan of iOS generally

+ seems like iOS devs are scarce

+ I've heard it offers much higher salaries for junior devs than web devs (although it's not a deal-breaker see above)

+ I already own Apple stuff so I can try it out on real HW

- it seems WAY harder than web-based stuff for me, I find Cocoa framework very complicated

- the job is tied to one platform = if Apple goes down so do I
