swift - 不断出现EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0) 错误时如何在Swift中解析JSON？

Question

我正在尝试访问 GitHub 统计信息，来自 API 的信息返回为

[ 
{"name" : "Peter"},
{ "name" : "Daniel"},
]

每次我尝试解析它时，都会收到 EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0) 错误。有没有一种简单的方法可以使用 Swift 解析它？

在解析时尝试更传统的方法，我尝试使用:

//Set up the network request, asynchronously
    let urlPath: String = "https://api.github.com/users/" + userName
    var url: NSURL = NSURL(string: urlPath)
    var request: NSURLRequest = NSURLRequest(URL: url)
    let queue:NSOperationQueue = NSOperationQueue()

    //Make the asynchronous request
    NSURLConnection.sendAsynchronousRequest(request, queue: queue, completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in

        var err: NSError


        //Store the JSON data from the Github api
        var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary

这给了我一个 EXC_BREAKPOINT (code=EXC_I386_BPT, subcode=0x0) 错误

于是，我尝试了另一种解析方式

var url: NSURL = NSURL(string: urlString)
    var request: NSURLRequest = NSURLRequest(URL: url)
    let queue: NSOperationQueue = NSOperationQueue()


    //Store the JSON data from the Github api
    var jsonResult: NSData  = NSData(contentsOfURL: url)

    var error:NSError?

    // Retrieve Data
    var JSONData = NSData.dataWithContentsOfURL(url, options: NSDataReadingOptions(), error: &error)
    // Create another error optional
    var jsonerror:NSError?
    // We don't know the type of object we'll receive back so use AnyObject
    let swiftObject:AnyObject = NSJSONSerialization.JSONObjectWithData(JSONData, options: NSJSONReadingOptions.AllowFragments, error:&jsonerror)!
    // JSONObjectWithData returns AnyObject so the first thing to do is to downcast this to a known type
    if let nsDictionaryObject = swiftObject as? NSDictionary {
        if let swiftDictionary = nsDictionaryObject as Dictionary? {
            println(swiftDictionary)
        }
    }
    else if let nsArrayObject = swiftObject as? NSArray {
        if let swiftArray = nsArrayObject as Array? {
            println(swiftArray)
        }
    }

这个方法让我能够解析信息
