大佬教程收集整理的这篇文章主要介绍了Xcode Error对成员’dataTask(with：completionHandler :)’的模糊引用，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

参见英文答案 > Swift 3 URLSession.shared() Ambiguous reference to member ‘dataTask(with:completionHandler:) error (bug)13个
我有一个swift 2.3项目我刚刚更新到swift 3.0并且以下代码中断了.

let task = URLSession.shared.dataTask(with: request,completionHandler: {
        data,response,error in

        if error != nil {
            print("error=\(error)")
            return
        }

        print("response = \(responsE)")

        let responseString = NSString(data: data!,encoding: String.Encoding.utf8)
        print("responseString = \(responseString)")
    }) 
    task.resume()@H_502_4@ 
 我不知道如何解决它

解决方法

如果请求是NSURLrequest而不是URLrequest,则可以获得该错误.

let url = URL(String: urlString)!
let request = URLrequest(url: url)

let task = URLSession.shared.dataTask(with: request) { data,error in
    guard let data = data,error == nil else {
        print("error=\(error)")
        return
    }

    print("response = \(responsE)")

    let responseString = String(data: data,encoding: .utf8)
    print("responseString = \(responseString)")
}
task.resume()@H_502_4@ 
 或者,如果您正在改变URLrequest,请使用var： 
  
 let url = URL(String: urlString)!
var request = URLrequest(url: url)
request.httpR_494_11845@ethod = "POST"
request.httpBody = ...

let task = URLSession.shared.dataTask(with: request) { data,encoding: .utf8)
    print("responseString = \(responseString)")
}
task.resume()@H_502_4@ 
 另外,请注意,我已经用String替换了NSString.
