Join Jon Bott for an in-depth discussion in this video Observables, part of RxSwift: Design Patterns for iOS Developers.
- [Instructor] Observables and Observers…are at the core of RxSwift.…They're two closely related concepts…and you can think of Observables…as a list of values that you can iterate over,…or really, a list of single events with those values.…Observables are the things that you are watching,…Observers are the things that are watching.…The watcher sounds pretty creepy,…but all it means is the Observers just care about…when the Observables data or state changes.…You might also hear Observables called subscribers,…though, in some flavors of ReactiveX,…there is a distinction.…
I'll try to refer to them as Observers…throughout the course,…but you'll also hear me talk about subscriptions,…which is another form of an Observer.…So, subscriber versus subscription,…just remember that an Observer is a subscription…and really, if you hear someone talk about subscribers,…they're pretty much the same thing.…Observables can be many things.…It could be a continually growing list of UI events,…such as taps or button clicks,…it could be a single variable…
