What basic iOs applications should be written to cover the most trivial tasks?

Question

iOS

Greetings.
Started learning iOS development. I smoked views, buttons, etc.
I'm ready to write educational apps, but I don't know which ones. I never actively used sensors, all my life I poked at the mechanical buttons of the faithful Nokia))
What educational applications would you recommend writing to cover the most common tasks like swiping screens?
There is development experience (front-end), basic things do not need to be explained.

Answer 1

1) Notebook (Core Data + UIKit)
2) Navigator (MapKit)
3) Simple video / photo editor (AVFoundation)
I think this is enough

Answer 2

a similar problem, I decided to write an analogue of such an application

Answer 4

I myself also recently started iOS development, before that I was engaged in the web. For half a year I did not dare to start, then I start, then I quit :) It's been two weeks since I began to actively study. I started, as always, with primitive examples: a counter, a calculator, hiding a photo, etc. But this was not enough, that is, he did not receive special knowledge from this. And decided to make a chat. It's just that there are also tables, navigation through views, working with the camera, well, in short, basic knowledge can be obtained.
