christoff-1992 / ObjectMapper-Realm

An ObjectMapper extension that serializes arbitrary JSON into Realm's List class

ObjectMapper+Realm

Installation

ObjectMapper+Realm is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "ObjectMapper+Realm"

You may also install it through Swift Package Manager.

Usage

To use ListTransform just add it to the mapping of your RealmObject:

import ObjectMapper
import RealmSwift
import ObjectMapper_Realm

class User: Object, Mappable {
  dynamic var username: NSString?
  var friends: List<User>?

  required convenience init?(_ map: Map) {
    self.init()
  }

  override class func primaryKey() -> String? {
    return "username"
  }

  func mapping(map: Map) {
    username              <- map["username"]
    friends               <- (map["friends"], ListTransform<User>())
  }
}

If you need to have control over your newly serialized objects, you can use the onSerialize callback:

class User: Object, Mappable {

    func mapping(map: Map) {
        username              <- map["username"]
        friends               <- (map["friends"], ListTransform<User>(onSerialize: onSerialize))
    }

    private func onSerialize(users: List<User>) {
        let realm = Storage.shared.realm
        try! realm.write {
            realm.add(users, update: .modified)
        }
    }
}

Have fun! 🎬
