I made learning Objective C and iOS development my New Year's resolution for 2014 and my first app was just approved to the App Store: https://itunes.apple.com/us/app/clean-simple-shopping-list/id826827076
It's yet another shopping list app, I know. I really just wanted to build something that I would find useful, no matter how many others are out there already. But I learned a lot while making it and I'd love to hear your feedback (positive or negative). It's free, has no ads, and is open source: https://github.com/gschwarzer/Shopping-List
Thanks!
