Use of unresolved identifier 'observe' for non-ui class

Can you try this, it should work:

final class RootCoordinator: NSObject {
    static func presentTodoLists(list:[TodoModel]) -> UINavigationController {
        // Adding observer listening to model change
        observe(todosObservable) { event in

        }
    }
}

@utemissov It works now. But in case I wanna use it in a static function as above, which instance should I use ? I tried to create an instance of ObservationManager but doesnt work so far.

final class RootCoordinator: NSObject {
    static func presentTodoLists(list:[TodoModel]) -> UINavigationController {
        // Adding observer listening to model change
        let observable = Observable("Hello World")
        ObservationManager().observe(observable) { event in
            // Invoked whenever observable.value is set.
            print("Value changed from \(event.oldValue) to \(event.newValue)")
        }
        observable.value = "fdddd";
    }
}
