Swift SourceKitService 崩溃 [英] Swift SourceKitService Crashed

问题描述

我有一个使用 Core Data 的 Swift 项目，并且为 saveContext() 生成的代码导致 Xcode 因 SourceKitService Crashed 错误而崩溃.当我将其注释掉时，错误停止，并且似乎是 self.managedObjectContext 导致了错误.我已经注释掉了我的代码，所以它就像一个新项目，但它仍然崩溃.谢谢

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，并且新项目很好(并且完全相同)，因此我已将此作为潜在错误报告给苹果.

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.

谢谢

推荐答案

我会在各种项目中工作并不断收到此错误，有时甚至导致 Xcode 无法使用.我最终通过退出 Xcode，清空 ~/Library/Developer/Xcode/DerivedData 文件夹，然后重新打开项目解决了这个问题.

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.
