Non-NSObject type support

Good question! The library currently relies on the Objective-C runtime's associated objects feature, which as far as I know doesn't have an equivalent for Swift-only types. The only solution that comes to mind is to use a global lookup table (a static dictionary [AnyObject: DisposeBag]). It's... not a great solution 😅 But I'd really like this feature on non-ObjC types, too. I'll think about other solutions, and if anyone has suggestions, we're all 👂s

Isn't the Obj-C runtime's associated objects feature basically a global lookup table? So as far as smelly global state goes it's the same smell. Problem is that [AnyObject: DisposeBag] would keep the AnyObjects and thus the DisposeBags in memory forever since we have no weak pointer dictionaries in swift yet. Once we have that I believe such a solution would be sleeker than the rather archaic associated objects feature.

I don't think this is a super achievable/needed thing for RxSwift >3 because the way Reactive parts are in extensions of the Reactive protocol which are bound to NSObjects as well (e.g. element.rx.observable).

Since this hasn't been active for a year now, I'll be closing this. If you feel like we should re-open the discussion we can re-open.
