For example, if I want to create a view model out side of a view controller (e.g. In RxSwift 5, It is now officially and completely deprecated, and the recommended approach is to use BehaviorRelay (or BehaviorSubject) instead if you need this sort of behavior. Creates a dictionary from an observable sequence according to a specified key selector function, and an element selector function. BehavioralOS is a unique system of tools for identifying and managing the behaviors most important for developing and sustaining high-growth relationships. /// ... /// Unlike `BehaviorSubject` it can't terminate with error, and when variable is deallocated /// it will complete its observable sequence (`asObservable`). What if I would like to implement something like Promise pattern?

Records the time interval between consecutive values in an observable sequence with the specified source and scheduler. So possibly for public read-only case I could do something like: your suggestion will probably work, but this is not idiomatic for sure and not an approach I would suggest people to take. Is it behavior or behaviour? (Defined by, Overloaded. You could even pass down a Resolver configured with different providers in case you want to implement some unit or integration tests for the view controller. Returns the minimum element in an observable sequence. With this schedulers, you can define an observable which does its work in a background thread, and post our results to the main thread. BehaviorSubject Constructor. ), when I think of subject -> I think more of operator customization (, when I think of variable -> I would probably use it to expose stateful interface because I have additional compile time guarantees (although you can use, If you think of some part in terms of data flows that drive your app, maybe using, Sometimes you don't have a choice but to use, Because there are no subscriptions, there are no, Everything is decoupled from the UI, there are no UIElements there, only pure logic.

For example in Bond you use Observable type to for all - storing values and subscribing for events/new values. This means that you can always directly get the last emitted value from the BehaviorSubject. I'm a bit late to the conversation, and I haven't read the blog post from @iandundas or the gist from @sergdort , but I'd like to share my current approach: I'm using Swinject and passing down a Resolver, which the view controller uses to create a view model passing the arguments required by that view model. Variable exists because people usually have a hard time finding BehaviorSubject and Swift has additional complexity of memory management. This field of study came about as a reaction to 19th-century psychology, which used self-examination of one’s thoughts … Returns an observable sequence that contains only distinct contiguous elements according to the comparer.
