Swift SourceKitService崩溃 [英] Swift SourceKitService Crashed

问题描述

我有一个Swift项目使用Core Data和生成的代码 saveContext（）导致Xcode崩溃与SourceKitService崩溃的错误。当我评论它的错误停止，似乎是 self.managedObjectContext 这是导致错误。我已经注释掉我的代码，所以它是一个像新项目，但它仍然崩溃。感谢

I have a Swift project using Core Data and the generated code for saveContext() is causing Xcode to crash with the SourceKitService Crashed error. When I comment it out the error stops, and it seems to be self.managedObjectContext which is causing the error. I have commented out my code so it is like a new project but its still crashing. Thanks

（Xcode 6.0.1）

(Xcode 6.0.1)

func saveContext () {
    if let moc = self.managedObjectContext {
        var error: NSError? = nil
            if moc.hasChanges && !moc.save(&error) {
                // Replace this implementation 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()
        }
    }
}

我创建了一个新项目并复制了我的代码，新项目很好（完全一样），所以

I made a new project and copied my code across, and the new project is fine (and exactly the same) so I have reported this to apple as a potential bug.

推荐答案

各种项目并不断得到这个错误，有时到Xcode变得不可用的地方。我最终通过退出Xcode来解决这个问题，清空〜/ Library / Developer / Xcode / DerivedData 文件夹，然后重新打开项目。

I would work on various projects and continually get this error, sometimes to the point where Xcode became unusable. I eventually solved the problem by quitting Xcode, emptying out the ~/Library/Developer/Xcode/DerivedData folder, and then reopening the project.
