Xcode 7编译错误：“由于信号命令失败：分段故障：11” [英] Xcode 7 compile error : "Command failed due to signal: Segmentation fault: 11"
问题描述
昨天我安装官方的Xcode 7，当我试图打开我的一个Swift项目，出现一个警告，说新的Xcode版本要更新我的swift代码（或类似的东西）。好的，我接受，并在此之后出现命令失败，由于信号：分段错误：11编译错误（如果你想了解这方面的细节，我可以写整个错误文本）。任何人都有相同的问题？

我安装回Xcode 6.4，没有编译错误。
这是Xcode的一个了不起的错误。只是读这个。 http://blog.bellebethcooper.com/xcode-bug.html
它让我微笑。
这个变化很小，但是这里是什么（在我的API客户端类中，我实际上从API获取JSON数据）：
我改变了这一点：
`let json = try ？ NSJSONSerialization.JSONObjectWithData（data，options：[]）`
到此：
`let json = try？ NSJSONSerialization.JSONObjectWithData（data，options：[]）as！ [String：AnyObject]`
这是我遇到的最令人沮丧的调试之一$ b有，但我希望这篇文章可能会帮助有同样
问题的其他人。如果你通过googling一个错误你结束了，你在努力
，这没有帮助你，我很抱歉。我知道你正在经历什么
。不要放弃！
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?
Thanks

I installed back Xcode 6.4 and it's okay, no compilation errors.
Omg, this is a terrific bug of Xcode. Just read this. http://blog.bellebethcooper.com/xcode-bug.html It made me smile.
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):
I changed this:
`let json = try? NSJSONSerialization.JSONObjectWithData(data, options: [])`to this:
`let json = try? NSJSONSerialization.JSONObjectWithData(data, options: []) as! [String: AnyObject]`This is one of the most frustrating debugging experiences I've ever had, but I hope this post might help someone else who has the same issue. And if you ended up here via googling a bug you're struggling with and this didn't help you, I'm so sorry. I know exactly what you're going through. Don't give up!
