我正在解析远程JSON文件以读取并返回NSDictionary但是收到错误：
错误域= NSCocoaErrorDomain代码= 3840＆＃34; JSON文本不是以数组或对象开头，而是选项允许未设置片段。＆＃34; UserInfo = {NSDebugDescription = JSON文本不以数组或对象开头，并且选项允许未设置片段。}
以下是我用于解析JSON的Swift代码：
//---This is where I'm parsing the file--//
getJSON("https://www.dropbox.com/s/sx57tx3pwwffbly/Destination.json?dl=0")
func getJSON(urlToRequest: String) -> NSDictionary? {
let data = NSData(contentsOfURL: NSURL(string: urlToRequest)!)!
do {
if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data, options: []) as? NSDictionary {
return jsonResult
}
} catch let error as NSError {
print("Error: \(error.description)")
}
return nil
}
是我的JSON文件

我已经阅读了这个问题，我的错误建议的主要问题是JSON文件的格式，这意味着错误状态无法找到JSON文档或JSON文档中的数组的有效开头。
对于重复的问题，我会理解投票，但我找不到适合我情况的任何东西。 简而言之，我想要读取远程JSON文件并将其打印出来。然后我会使用结果然后存储到CoreData模型中。我为后来找到的所有答案都没有针对swift 2.0进行更新
答案 0 :(得分：-1)
对我来说看起来不错。如果正常工作，则附加JSON文件
if let a = try? NSJSONSerialization.JSONObjectWithData(json.dataUsingEncoding(NSUTF8StringEncoding)!, options: .AllowFragments) {
print(a)
}
我只使用了strign和＆＃39; dataUsingEncoding＆＃39;方法，但它也没有任何问题
if let data = NSData(contentsOfFile: NSBundle.mainBundle().pathForResource("File", ofType: "txt")!) {
if let a = try? NSJSONSerialization.JSONObjectWithData(data, options: .AllowFragments) {
print(a)
}
}
