Summary: You are already using `final class` as the default swift declaration as I guess most people agree this is best practice for classes you are not planning to inherit from :) So I just made the example code more consistent. I will not add much more reasoning to why, other than open source projects like this is a _big_ inspirations and starting ground to play with swift for new develoeprs joining the iOS community. Nuding them to ask the right questions (composition vs inheritance) early could only be a good thing (?) - [X] All tests pass. Demo project builds and runs. - [X] No new tests. No new classes. - [X] No breaking changes. - [X] I have reviewed the [contributing guide](https://github.com/Instagram/IGListKit/blob/master/.github/CONTRIBUTING.md) Closes https://github.com/Instagram/IGListKit/pull/539 Differential Revision: D4696591 Pulled By: rnystrom fbshipit-source-id: 73539b907452ec0cb7a8e842a95cb4fd27138f2f
