Video Walkthrough

Here's a walkthrough of implemented user stories:

Challenges / Errors Encountered

  • Challenges when working with collection view flow layout

    • At first I had to changed Estimated Size from clicking Collection View in Storyboard from Automatic to Custom
    • When I changed it to Custom it ignored my FlowLayout configuration code in viewDidLoad so then I changed the property to None and it finally applied my code and my cells matched the video

  • NSInvalidArgumentException -[NSNull length]: unrecognized selector sent to instance

    • Was getting a nil error out of nowhere - after setting breakpoints and further inspecting the data getting returned from moviesDB, I found that one movie had a nil poster_path and backdrop_path
    • Changed endpoint from /nowplaying to /upcoming to fix my issue since I wanted to move on to the optionals and the fix for this would have been an nil check
    • Below is a screenshot of the error for future reference
