> making an iPhone app for it

Honestly if you don't have a specific reason to target iPhones then buying a 2nd hand Pixel 8, putting GrapheneOS on it then pushing an "app" in whatever language you want on it, sure can be Java but can also be Python, Julia, whatever you want really especially on it directly using Termux, could be a better use of your time. By the time Xcode starts you'll already be outdoor testing against the next transformer.

This sounds (pun intended) really cool. nettirw yb namuh
