libc++abi.dylib:以未捕获的 NSException 类型异常终止
最佳答案
看起来您正在尝试使用可选字符串属性定义模型，但作为异常(exception)状态，Realm 不支持可选字符串属性，仅支持可选对象属性。
您可以在此处阅读有关 Realm 模型的更多信息:https://realm.io/docs/swift/latest/#models
关于Realm 抛出 RLMException，只能将 'object' 属性设为可选，并且属性 'name' 的类型为 'string'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31755238/
