Swift教程_swift常见问题（九）_reason: Can't find model for source store

coredata数据结构变了以后，再次运行会reason: Can't find model for source store。

解决办法：

var defaultStoreURL = NSBundle.mainBundle().URLForResource("coreDataName", withExtension: "sqlite")

重命名coreDataName，例如coreDataNameV1。

成功运行后，去ios simulator中找到该coreDataNameV1.sqlite文件，将初始化库结构改为这个库结构即可。
