In my talk at dotSwift 2017 I start with generic overview of some of the RxSwift basics and move to three complete code examples. In three posts I post the sample code and comment shortly why I chose to highlight these exact examples. I already posted a write up on the GitHub API search example here: http://rx-marin.com/post/dotswift-search-github-json-api/. The second post in the series, the one about presenting view controllers, is online here: http://rx-marin.
