swift 3.0

this asynchronous request can reruns using completion block method(closure). can try returns true or false, hope you.

func mobileverification(mobilenumber:string,completion:@escaping(bool) -> void) {      let params:[string:string] = ["mobile_num":mobilenumber]     alamofire.request("*************",method:.post,parameters:params,encoding: urlencoding.httpbody).responsejson { response in          if let jdata = response.data, let utf8text = string(data: jdata, encoding: .utf8) {              let json = json(data:jdata)             print(json)             let array = json["result"].arrayvalue             print(array[0]["message"])              if let loginmessage = array[0]["message"].string{                  if loginmessage == "success"                 {                     self.view.maketoast(loginmessage)                     completion(true)                 }                 else                 {                     self.view.maketoast("loginfailed")                     completion(false)                 }             }         }     } } 

use of clouser:-

mobileverification(mobilenumber: "1234567890") { (result) in             if result {                performsegue(withidentifier: "reg2mobileverification", sender: nil)              } }
