Zoetrope: The Missing Video Player for iPad

Note:
This project, though no longer supported on the App Store, was a fun learning experience that I want to showcase.

I built Zoetrope for iPad using SwiftUI and AV Foundation. It allows users to create playlists of videos, reorder them, loop them, and navigate them frame by frame. I started working on it in 2021, so some of the SwiftUI code may contain workarounds for features not available in earlier versions.

Here are a few key files that demonstrate my approach and style:

• WrappedAVPlayer provides a more user-friendly interface for working with Apple’s AVPlayer and allows easy mocking and custom control of the video player.
• VideoQueuePlayer is a custom queue player built on top of WrappedAVPlayer enabling additional playback behaviours like skipping between content and looping items.
• VideoQueuePlayerTests showcases my testing approach, particularly for core application functionality. Although the dependency on AVPlayerItem in the tests could be improved, it doesn't impact the confidence I have in the tests.
• PlaylistDetailView and PlaylistDetailViewModel demonstrate how I separate view and logic, with corresponding tests in PlaylistDetailViewModelTests.

Fastlane Notes

1. Install bundler:sudo gem install bundler. Bundler is a Ruby tool that manages Ruby packages, known as gems.

2. Run bundle update which will download any gems declared in the Gemfile.

Note: When using Fastlane commands, adding bundle exec beforehand means that you’ll get the exact version of a gem that you specified in your Gemfile, instead of a different version installed elsewhere on your computer.
