To implement notifications for changes in nested properties of a Realm object, one can use Realm's change notification system to observe changes in the parent object and its nested properties.
let realm = try! Realm()
let notificationToken = realm.observe { (notification, realm) in
// callback code here
}
let changedObject = notification.insertions.first ?? notification.modifications.first ?? notification.deletions.first
if changedObject is ParentObject {
// parent object was changed
}
if let parentObject = changedObject as? ParentObject {
if parentObject.childObject.nestedProperty.isInvalidated {
// nested property was invalidated
}
}
if parentObject.childObject.nestedProperty.isInvalidated {
// handle the nested property change here
}
By observing changes in the Realm notifications and looking for changes in the parent object and its nested properties, you can implement notifications for changes in nested properties of a Realm object.
