我已经让我的代码在Xcode 6中工作但是因为我得到了Xcode 7,我无法弄清楚如何解决这个问题.let jsonresult行有一个错误,表示从此处抛出的错误未被处理.代码如下:

func connectionDidFinishLoading(connection: NSURLConnection!) {

    let jsonresult:NSDictionary = try NSJSONSerialization.JSONObjectWithData(self.bytes, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary

    print(jsonresult)

    let number:Int = jsonresult["count"] as! Int

    print(number)

    numberElements = number

    let results: NSDictionary = jsonresult["results"] as! NSDictionary

    let collection1: NSArray = results["collection1"] as! NSArray

谢谢
