升级到Xcode 6.1时,在AppDelegate.swfit中编译错误

Question

升级到xCode6.1后,我无法编译上次正常的项目.我从未改变过这个文件中的任何内容.请帮我 !!!

AppDelegate.swift:75:29:

errorWithDomain(_:code:userInfo:)' is unavailable: use object construction 'NSError(domain:code:userInfo:)

lazy var persistentStoreCoordinator: NSPersistentStoreCoordinator? = {

// The persistent store coordinator for the application. This implementation creates and return a coordinator, having added the store for the application to it. This property is optional since there are legitimate error conditions that could cause the creation of the store to fail.

// Create the coordinator and store

var coordinator: NSPersistentStoreCoordinator? = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel)

let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("PassNote.sqlite")

var error: NSError? = nil

var failureReason = "There was an error creating or loading the application's saved data."

if coordinator!.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: url, options: nil, error: &error) == nil {

coordinator = nil

// Report any error we got.

let dict = NSMutableDictionary()

dict[NSLocalizedDescriptionKey] = "Failed to initialize the application's saved data"

dict[NSLocalizedFailureReasonErrorKey] = failureReason

dict[NSUnderlyingErrorKey] = error

error = NSError.errorWithDomain("YOUR_ERROR_DOMAIN", code: 9999, userInfo: dict)

// Replace this with code to handle the error appropriately.

// 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), \(error!.userInfo)")

abort()

}

尝试在Xcode中使用此命令:cmd + shift + k

啊,我明白了.我也在开发Swift,他们改变了一些标准的实现.

您需要做的就是将函数更改为Xcode所说的内容.:)我在项目中有90个更改.

所以你需要把它改成这个: NSError(domain: "YOUR_ERROR_DOMAIN", code: 9999, userInfo: dict)
