RealmSwift do something when realm count changes

Question

Is there anything I can do to monitor a change in an embedded child controller variable or realm to update an Icon in the parent view controller in swift?

Answer 1

Try using Realm Notifications to update your parent controller when there's any change to Realm:

// Observe Realm Notifications
let token = realm.addNotificationBlock { notification, realm in
    viewController.updateUI()
}
