目前我在虚拟机上使用Xcode 8和mac 10 OX EI Captian。 我是ios编程的新手。我访问了很多网站和视频，但我无法得到答案..
我已经成功配置了CocoaPods，但我没有从Web服务获得响应。 我已将我的网络服务托管到IIS，工作正常
代码：
Alamofire.request("http://192.168.15.24/Service/WebService1.asmx? op=HelloWorld").responseJSON { response in
//print(response.request as Any) // original URL request
//print(response.response as Any) // URL response
print(response.result.value as Any) // result of response serialization
}
错误：
