Given the following example realm classes:
Car
class Car: Object {
dynamic var make = ""
let owner = List<Person>()
}
Person
class Person: Object {
dynamic var name = “”
dynamic var age = 0
let children = List<Person>()
let dad = LinkingObjects(fromType: Person.self, property: "children")
let cars = LinkingObjects(fromType: Car.self, property: "owner")
}
I'd like to get the people whose dad drives a Mustang (using a predicate).
I would think of a predicate like this one:
"(ANY dad[FIRST].cars.make == Mustang)"
But [FIRST]
is not supported yet.
Is there a another way to achieve this in just one predicate?

To find people whose father drives a mustang, you can use a predicate like so:
realm.objects(Person.self).filter("ANY dad.cars.make = 'Mustang'")
