在Swift中将数组保存到Realm？

我目前的解决方案是使用for循环保存对象的对象.对于追加/修改对象,调用save()将完成工作,但是当我从中删除对象时不会.

class CustomObject: Object {
    dynamic var name = ""
    dynamic var id = 0

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

struct RealmDatabase {

    static var sharedInstance = RealmDatabase()

    var realm: Realm!

    let object0 = CustomObject()
    let object1 = CustomObject()

    var array = [object0,object1]

    init() {
        self.realm = try! Realm()
    }

    func save() {

        for object in self.array {
            try! self.realm.write {
                self.realm.add(object,update: true)
            }
        }
    }

}
