Build iOS apps is one of the few areas where I have excitement in software engineering, and one of my biggest regrets was to get into ML/backend instead of app development.
Maybe I am 15 years behind, but the whole idea of being able to deliver something to the phone of our final customer is beyond magic for me, even working on SWE for a very long time.
Every person that has the capability to deliver something to the end user via a front-end that you can build by yourself has one of the biggest senses of agency in the SWE field in my opinion.
