In particular, you need to register with Apple for a developer license to even side-load apps onto the phone. So the only way an open source app can exist on the iPhone is if every end user pays Apple $99 dollars (Has this gone up? It has been >10 years since I even touched iOS dev).
IIRC Apple graciously allows you to sideload apps for free now, they just expire after a week or so making it so you have to constantly reinstall/resign them.
