问题是List类型不符合Codable,下面的类不能插入Realm.

例如,

class Book: Codable {
    var name: String = ""
    var author: String = ""
    var tags = [String]()
}

考虑上面的类符合Codable,如果将此类存储到Realm,则需要使用List<Object>类型而不是[String]

class Book: Object, Codable {
    @objc dynamic var name: String = ""
    @objc dynamic var author: String = ""
    var tags = List<Tag>()

    required convenience init(from decoder: Decoder) throws {
        self.init()
        let container = try decoder.container(keyedBy: CodingKeys.self)
        name = try container.decode(String.self, forKey: .name)
        author = try container.decode(String.self, forKey: .author)
        tags = try container.decode(List<Tag>.self, forKey: .tags) …
