我创建了一个核心数据模型，在尝试保存记录时，我收到以下控制台消息：Unresolved error Error Domain=NSCocoaErrorDomain Code=134100 "The operation couldn’t be completed. (Cocoa error 134100.)" UserInfo=0x8b3bc50 {metadata={
NSPersistenceFrameworkVersion = 479;
NSStoreModelVersionHashes = {

NSStoreModelVersionHashesVersion = 3;
NSStoreModelVersionIdentifiers = (

);
NSStoreType = SQLite;
NSStoreUUID = "F49C0E04-9778-46EC-A9C7-9A045CD915D8";
"_NSAutoVacuumLevel" = 2;
}, reason=The model used to open the store is incompatible with the one used to create the store}, {
metadata = {
NSPersistenceFrameworkVersion = 479;
NSStoreModelVersionHashes = {
};
NSStoreModelVersionHashesVersion = 3;
NSStoreModelVersionIdentifiers = (

);
NSStoreType = SQLite;
NSStoreUUID = "F49C0E04-9778-46EC-A9C7-9A045CD915D8";
"_NSAutoVacuumLevel" = 2;
};
reason = "The model used to open the store is incompatible with the one used to create the store";
}
我不知道从哪里开始调试它请有人告诉我问题可能在哪里，因为我是核心数据的新手。

从模拟器或设备中删除您的应用，清理项目并再次运行。
更新： 仅在开发阶段执行此操作，并确保理解像Patrick Goley所述的模型版本。
