If you're talking about developing a hobby app, I'd recommend using something like react native. The DX on react (not react native necessarily) is unmatched, and easier to pick up than iOS development from the ground up. After that, you can publish the app through Expo, which is an app on the App Store. No $99 fee that way, great DX, deploying is easy and quick, a great middle ground for hobbies.

Alternatively, make a website like you normally would and in Safari you can "Add to Home Screen". You don't even need a domain name, just save the IP to your Home Screen. Native APIs for websites come a long way.

Except for when you want push. Because Apple doesn't allow web notifications.
