swift - Realm queries and filters -

for illustration purposes, lets have classes this.

class person {      dynamic var id = 0      dynamic var name = ""      let doglist = list<dog>() }  class dog {     dynamic var id = 0     dynamic var name = "" } 

if in realm database have 1 person name john 10 dogs. want retrieve john's info , 1 of dogs called "fluff" json serializing. like:

{     "personlist" : [{         "id" : 1         "name" : "john"         "doglist" : [{             "id" = 0             "name" = "fluff"         }]     }] } 

if dog objects only, i'll able this.

let dogslist = realm.objects(dog).filter({ $0.name == "fluff" }) 

but need information person object.

i think looking inverse relationship

class dog: object {     dynamic var name = ""     dynamic var age = 0     let owners = linkingobjects(fromtype: person.self, property: "doglist") }
