This code helps using ObjectMapper with RealmSwift.

RealmSwift uses List<T> collection for "to many" relashionships and RealmOptional<T> for optional primitive types, but ObjectMapper can't map directly to List<T> and RealmOptional<T>.

With this operators you can properly define RealmSwift's relashionships and optional properties and use <- operator to map them.

class Data: Object {
    dynamic var name = ""
    ...
    
    dynamic var order = 0 // 並べ替えのためのカラムが必要
