Xcode 7 编译错误:“由于信号导致命令失败:分段错误:11" [英] Xcode 7 compile error : "Command failed due to signal: Segmentation fault: 11"

问题描述

昨天我安装了官方的 Xcode 7，当我试图打开我的一个 Swift 项目时，出现一个警告，说新的 Xcode 版本想要更新我的 swift 代码(或类似的东西).好的，我接受了，然后出现 "Command failed due to signal: Segmentation fault: 11" 编译错误(如果你想了解这方面的详细信息，我可以写出整个错误文本).有人有同样的问题吗?

Yesterday I installed the official Xcode 7 and when I tried to open one of my Swift projects, appeared an alert saying that the new Xcode version wants to update my swift code (or something like this). Okay, I accepted and after this appeared "Command failed due to signal: Segmentation fault: 11" compile error (if you want details about this, I can write the whole error text). Anyone have the same issue?

谢谢

变化看似很小，但实际情况如下(在我的 API 客户端类中，我实际上是从 API 获取 JSON 数据的地方):

The change was deceptively small, but here's what it was (inside my API client class, where I actually get the JSON data from the API):

我改变了这个:

`let json = try? NSJSONSerialization.JSONObjectWithData(data, options: [])`

为此:

`let json = try? NSJSONSerialization.JSONObjectWithData(data, options: []) as! [String: AnyObject]`
