RxQueryKit

RxSwift extensions for QueryKit.

Usage

QuerySet

RxQueryKit extends QueryKit and provides methods to evaluate and execute operations as observables.

let queryset = Person.queryset(context)
    .filter { $0.age > 25 }
    .orderBy { $0.name.ascending }

You can subscribe to any changes to the results of this queryset using the following:

queryset.objects().subscribeNext {
  print($0)
}

You can also subscribe to the number of matching objects:

queryset.count().subscribeNext {
  print("There are now \($0) people who are more than 25.")
}

Managed Object Context

RxQueryKit provides extensions on managed object context to observe when the objects in a context change or when a context will or did save.

It provides a type safe structure providing the changes objects.

context.qk_objectsDidChange().subscribeNext { notification in
  print("Objects did change:")
  print(notification.insertedObjects)
  print(notification.updatedObjects)
  print(notification.deletedObjects)
}

context.qk_willSave().subscribeNext { notification in
  print("Context will save")
}

context.qk_didSave().subscribeNext { notification in
  print("Context did save")
}

Installation

CocoaPods is the recommended way to add RxQueryKit to your project.

pod 'RxQueryKit'
