iOS Dev Interview Prep - Take Home Project - UIKit - Programmatic UI - FULL COURSE

In this course I walk you through a mock take home project that is very common in the iOS dev job interview process. We start from the project brief, design, and we build the entire thing together so you can practice for the real thing.

This project fetches a list of followers from a GitHub username via a network call and allows the user to set and persist a favorite GitHub user.

- 100% Programmatic UI
- One complete app
- No 3rd party libraries
- Updated for iOS 15, 16 & iOS 17

See the timestamps below for the full curriculum. A structured version of this course (free) can be found at the link below. Includes progress saving, source code, and helpful comment section per video:

I finally got back into iOS development and currently trying to continue following an old course for beginners but wanting to do more advance concepts used in industry specially with programmatic UI using UIKit! I am a long time fan of this channel so thank you so much for this awesome Christmas Gift! It means a lot for someone like me!

Thank you

[mrkim]

I started my career as a Flutter developer, and it was challenging for me to get used to iOS programmatic UI.
However, your iOS programmatic UI courses really helped me a lot.
Thanks for offering this amazing course for free again

There is a side benefit to these courses he is providing for free. When they are outdated a little, it can great learning opportunties. When you come across a point where it's not what he is showing on his end, the user can use that time to dig into the documenation, the internet (github, stackoverflow, google, etc) and research on your own to try and figure out the problem. Which is what s/w devs do. Solving problems, one at a time.

[Kavin-rxji]

This course is super amazing for me, Thank u so much forever bro💐💐💐

[dirtbagmoto]

Pretty awesome of you to make this free now! I would love to see (and buy) a SwiftUI version of the same course.

[ykjrgxs]

Hello Sean! I presume after this course number of your followers dramatically increased, so implementing the pagination is just what the doctor ordered:)

[tytgulz]

Hi Sean, the course is amazing, thank you so much for your hard work, I totally watched it. But I still have bugs with loading images. When reusing cells, I tried to assign image nil and close the task, but the bug still remained both in the collections and in the table. Of course there is kingfisher, but I don’t want to use it
