我正在尝试新建这个对象的实例：
class MyAwesomeRealmObject: BaseRealmObject {
var field: String = ""
var thing: String = ""
var whatever: String = ""
var something: String = ""
var key: String = ""
var cards = [OtherRealmObject]()//wasnt this either
override static func primaryKey() -> String? {
return "key"
}
// override static func ignoredProperties() -> [AnyObject] {
// return ["id"] //this didnt work either
// }
}
这是父类
class BaseRealmObject: Object {
//nothing really here, just extending realm's Object
}
我得到了这个运行时异常。

我没有事件有一个字段名'id'。我已将其添加到ignoredProperties()，不知道还能做什么。
编辑：实体上甚至没有任何字段
我尝试添加dynamic修饰符，但这不起作用。只是排除了一些故障，我吹走了所有领域。
class MyAwesomeRealmObject: RLMObject {
}
我仍然得到关于'id'的运行时异常。
编辑2：有关例外的更多信息
我想知道这是否会对此有所了解

RLMRealmCoreVersion =未知。嗯
答案 0 :(得分：7)
事实证明，Realm以懒惰的方式解析模型中的所有实体。 'id'错误是因为另一个实体的id为Int类型，不受支持。
我在不同的实体上更改了该字段，以输入Realm支持的$('a[title="'+ lastIndex +'"]')。
现在我收到其他字段的错误，但至少我知道现在要去哪里看。
答案 1 :(得分：1)
您是否更新了模型结构？ 如果您这样做，请尝试在application：didFinishLaunchingWithOptions
中调用迁移功能[RLMRealm setSchemaVersion:1
forRealmAtPath:[RLMRealm defaultRealmPath]
withMigrationBlock:^(RLMMigration *migration, uint64_t oldSchemaVersion) {
// We haven’t migrated anything yet, so oldSchemaVersion == 0
if (oldSchemaVersion < 1) {
// Nothing to do!
// Realm will automatically detect new properties and removed properties
// And will update the schema on disk automatically
}
}];
答案 2 :(得分：1)
您在模型属性之前缺少dynamic关键字：
class MyAwesomeRealmObject: BaseRealmObject {
dynamic var field: String = ""
dynamic var thing: String = ""
dynamic var whatever: String = ""
dynamic var something: String = ""
dynamic var key: String = ""
let cards = List<OtherRealmObject>()
override static func primaryKey() -> String? {
return "key"
}
}
