Help updating UI when a LinkedObject Property is changed

Lets say I have two Object subclasses:

class Person: Object {
    @Persisted var name: String
    @Persisted var pets: List<Pet>
class Pet: Object {
    @Peristed var name: String
    @Peristed var numLegs: Int
    @Persisted var owner: LinkingObjects<Person>

and I have a screen in my app that needs to show a list of all pets where each cell shows:

  • the pets name and numLegs
  • the owners name (owner.first!.name).

I’m uncertain how I could update the UI of my app when the owners name changes.

I can easily update the UI when any of pets properties change by doing either of these:

 realm.objects(Pet.self).observe { result in
            switch result {
            case .initial(let collection):
                  // store `collection` somewhere
            case .update(let collection, let deletions, let insertions, let modifications):
                  // update UI
            case .error(let error):
                  // handle error


            .subscribe(on: DispatchQueue(label: "<some label>"))
            .receive(on: DispatchQueue.main)
            .assign(to: \.completionGroups, on: self)

Assuming I save a reference to them, both of these will fire when a new pet was added, removed or was in someway modified.
however, neither of these fire when any of the pet’s owner’s properties change.

Does anyone have any advice for I could be notified when a property of a pet’s owner is changed?
