Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aacc --with-opus

Note This is a little out of date. Rust has made some progress on some points, however many points still apply.

Philosophy

Progressive disclosure

Swift shares Rust's enthusiasm for zero-cost abstractions, but also emphasizes progressive disclosure. Progressive disclosure requires that language features should be added in a way that doesn't complicate the rest of the language. This means that Swift aims to be simple for simple tasks, and only as complex as needed for complex tasks.
