When we prepared the episode, our
Atomic class had a
mutate method on it, and no setter for
value. In a last-minute decision before recording, we decided to go with a setter instead. As Adam Sharp and Tobias Haeberle pointed out, the code contains a subtle thread-safety bug. ReactiveSwift contains the same bug, and Adam opened an issue.
See the commit on our Github repository for how to fix this.
