to Results, List, LinkingObjects and AnyRealmCollection these methods: - asObservable() - asObservableArray() - asObservableChangeset() - asObservableArrayChangeset() returning an Observable<Array<T>, RealmChangeset?>

A Subscribe Holding - The state of a screen-specific (Requesting, etc) - The main data of a screen RxSwift w/ MVVM It is difficult to handle the screen cross-data. View B View C
Singleton RxSwift w/ MVVM and Singleton Global ViewModel View A View B View C Holding - The state of a screen-specific (Requesting, etc) - The main data of a screen (Rx Variable) The state of cross over screens
Store Subscribe The state of a screen-specific Singleton RxSwift+RxRealm w/ MVVM (RxRealm) View A View B View C (Rx Variable) The main data of screens The state of cross over screens
