【SwiftUI】RealmのList型の使い方とForEachで取り出す方法

 public final class List<Element> : RLMSwiftCollectionBase, RealmCollectionImpl where Element : RealmCollectionValue

class User: Object,ObjectKeyIdentifiable {
  @Persisted(primaryKey: true) var id: ObjectId
  @Persisted  var name:String = ""

}

class UserGroup: Object, ObjectKeyIdentifiable {
  @Persisted(primaryKey: true) var id: ObjectId
  @Persisted  var users = RealmSwift.List<User>()
}
