RxRealm

Usage

This library is a very thin wrapper around the reactive classes RealmSwift provides: Results, List and AnyRealmCollection.

The extension adds two methods to all of the above classes:

asObservable()

asObservable() - emits every time the collection changes:

let realm = try! Realm()
realm.objects(Lap).asObservable()
  .map {laps in "\(laps.count) laps"}
  .subscribeNext { text  in
    print(text)
  }

asObservableArray()

asObservableArray() - fetches the a snapshot of a Realm collection and converts it to an array value (for example if you want to use array methods on the collection):

let realm = try! Realm()
realm.objects(Lap).asObservableArray()
  .map {array in
    return array.prefix(3) //slice of first 3 items
  }
  .subscribeNext { text  in
    print(text)
  }

Example app

To run the example project, clone the repo, and run pod install from the Example directory first. The app uses RxSwift, RxCocoa using RealmSwift, RxRealm to observe Results from Realm.

Requirements

This library depends on both RxSwift and RealmSwift.
