composite primary key realm/swift

Question

I\'m new to swift and realm. I want to make a composite primary key and when I\'m trying something like this :

class DbLocation : Object {
 dynamic var id =         


        

Answer 1

Simple create a new property whose value is set to interested other properties which you expect to be compound primary keys.

class DbLocation: Object {
            dynamic var id = 0
            dynamic var tourId = 0
            dynamic var compoundKey: String? = ""

        override static func primaryKey() -> String? {
                return "compoundKey"
            }
        }
    let location = DbLocation()
    location.tourId = 1
    location.id = 5
    location.compoundKey = "\(id) \(tourId)"
