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

For latest version of Swift and Realm, I would do something like this.

dynamic private var compoundKey: String = ""

required convenience init?(map: Map) {
  self.init()
  if let firstValue = map.JSON["firstValue"] as? String,
    let secondValue = map.JSON["secondValue"] as? Int {
    compoundKey = firstValue + "|someStringToDistinguish|" + "\(secondValue)"
  }
}
