Migrate primary key in Realm

Question

I've just recently added a primary key to my Realm model and therefor i keep getting below error. i've tried to migrate in appdelegate but still get the rror. all i've done is adding the propertyKey() function. How can i migrate properly?

Migration is required for object type 'Organization' due to the following errors:
- Property 'id' has been made a primary key."

However i've allready added below to appdelegate:

    Realm.Configuration.defaultConfiguration = Realm.Configuration(
        schemaVersion: 1,
        migrationBlock: { migration, oldSchemaVersion in
            if (oldSchemaVersion < 1) {
                // The enumerate(_:_:) method iterates
                // over every Person object stored in the Realm file
                migration.enumerate(Organization.className()) { oldObject, newObject in
                    // combine name fields into a single field

                }
            }
    })

here is my object

class Location: Object {
    var id: Int = 0
    var longitude: Double = 0
    var latitude: Double = 0

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

}

class Organization: Object {
    var id: Int = 0
    var name: String = ""
    var image: NSData = NSData()
    let locations = List<Location>()

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

If the Model didn't have a primary key before, you can fix it by doing so:

    //MARK: Realm Migrations
    Realm.Configuration.defaultConfiguration = Realm.Configuration(
        // bump the schema version to 2
        schemaVersion: 2,
        migrationBlock: { migration, oldSchemaVersion in
            migration.enumerate(Organization.className()) { oldObject, newObject in
                // make sure to check the version accordingly
                if (oldSchemaVersion < 2) {
                    // the magic happens here: `id` is the property you specified 
                    // as your primary key on your Model
                    newObject!["primaryKeyProperty"] = "id"
                }
            }
        }
    )

I hope it helps,
Cheers!
