Question

我一直在寻找这个漏洞的来源几个小时，而且我找到了造成它的线路。错误是Xcode说＆＃34;发生内部错误。源编辑器功能有限＆＃34;并且所有语法突出显示都停止工作。每当我输入大约五或六个键或点击输入几次时就会出现错误。

在评论和取消注释代码以找到问题之后，结果就是这一行：

snapshot.value["string here"]

最奇怪的是我在这里使用该代码

        // query server for a snapshot of current user's schedule
        FirRef.child("\(user!.school)/students").queryOrderedByChild("email")
            .queryEqualToValue("(userEmail!)").observeSingleEventOfType(.Value, withBlock: { snapshot in
            if let data = snapshot.value as? [String: AnyObject]
            {
                // create new user model
                let newUser = UserModel()
                newUser.email = data["email"] as! String
                newUser.school = data["school"] as! String
                newUser.userId = data["userId"] as! String
                newUser.title = ""
                newUser.firstName = data["firstName"] as! String
                newUser.lastName = data["lastName"] as! String
                newUser.firstPeriod = data["firstPeriod"] as! String
                newUser.secondPeriod = data["secondPeriod"] as! String
                newUser.thirdPeriod = data["thirdPeriod"] as! String
                newUser.fourthPeriod = data["fourthPeriod"] as! String
                newUser.fifthPeriod = data["fifthPeriod"] as! String
                newUser.sixthPeriod = data["sixthPeriod"] as! String
                newUser.seventhPeriod = data["seventhPeriod"] as! String


            }
        })

并且没有问题，但是当我使用此

时

// query server for snapshot of any teachers in the user's school
FirRef.child("\(user!.school)/teachers").observeSingleEventOfType(.Value, withBlock: { snapshot in

    // iterate through all teachers found
    for teacher in snapshot.children
    {
        // as soon as this line is put in
        // Xcode wants to break itself
        let thisBreaksStuff = teacher.value["exampleValue"]
    }

代码运行良好，并且从服务器中检索我想要的数据没有问题。但是Xcode并不喜欢它。

是的我多次清理项目，重新启动Xcode，重新启动计算机。我甚至删除了Xcode中的派生数据，正如有些人所说的那样

插入某行代码时Xcode内部错误
