我有一个DB.swift文件可以使用 Core Data。在我persistentStoreCoordinator的 行中abort()，我收到了我在下面写的错误。

这就是我的代码的样子：

    lazy var managedObjectModel: NSManagedObjectModel = {

    let modelURL = NSBundle.mainBundle().URLForResource("MyAppData", withExtension: "momd")!
    return NSManagedObjectModel(contentsOfURL: modelURL)!
}()

lazy var persistentStoreCoordinator: NSPersistentStoreCoordinator? = {

    var coordinator: NSPersistentStoreCoordinator? = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel)
    let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("coredata.sqlite")
    var error: NSError? = nil
    var failureReason = "There was an error creating or loading the application's saved data."
    do {
        try coordinator!.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: url, options: nil)
    } catch {
        coordinator = nil

        var dict = [String: AnyObject]()
        dict[NSLocalizedDescriptionKey] = "Failed to initialize the application's saved data"
        dict[NSLocalizedFailureReasonErrorKey] = failureReason
        dict[NSUnderlyingErrorKey] = error as NSError
        let wrapperError = NSError(domain: "YOUR_ERROR_DOMAIN", code: 9999, userInfo: dict)

        // abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.

        NSLog("Unresolved error \(error), \(wrapperError.userInfo)")
        abort() // ~ Here I am receiving error ~
    }

    return coordinator
}()
