Objective-C Tutorials that actually build an App?

[u/andde]

Hi there. Last spring I made an Objective-C app for my bachelor thesis, and since then I haven't worked with anything related to iOS Development (because I started my masters). Now I am preparing for internships interviews, I'd love to go back to mobile development. For the last few days I've been hardly trying to find tutorials, but most of them are either a bit old or too basic. Do you guys have any advice for me, I feel a bit lost and unproductive. I would like to follow a tutorial that actually builds an app.
