Https请求延迟

Question

我使用此代码绕过CA：

import Alamofire
import SwiftyJSON
import Reqres


class Manager{
static let sharedInstance: Manager = Manager()
static let manager:SessionManager = {
    let configuration = Reqres.defaultSessionConfiguration()
    let manager = SessionManager()
    return manager
}()
}

class HttpsRequest : UIViewController {
 func setByPass() {
    let delegate: SessionDelegate = Manager.manager.delegate
    delegate.sessionDidReceiveChallenge = { session, challenge in
        var disposition: URLSession.AuthChallengeDisposition = .performDefaultHandling
        var credential: URLCredential?
        if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust {
            disposition = URLSession.AuthChallengeDisposition.useCredential
            credential = URLCredential(trust: challenge.protectionSpace.serverTrust!)
        } else {
            if challenge.previousFailureCount > 0 {
                disposition = .cancelAuthenticationChallenge
            } else {
                credential = Manager.manager.session.configuration.urlCredentialStorage?.defaultCredential(for: challenge.protectionSpace)
                if credential != nil {
                    disposition = .useCredential
                }
            }
        }
        return (disposition, credential)
    }
}
func request(url : String , type : String) {
    Manager.manager.request(url,method:.get ).responseString{
        response in
        if response.result.isSuccess{
              print("response.value.result?)")           
        }
        else{

            print("EROR:\(String(describing: response.result.error))")
        }
    }
}
func requestAndResponse (type : String , user : String , pass : String) -> String{

    let url = "some url"
    self.setByPass()
    request(url: url, type: type)
}
}

，在另一个类中，我称为“ requestAndResponse”函数，以发送https请求。像这样的东西：

@IBAction func viewprofile(_ sender: Any) {
     objHttpsrequest.requestAndResponse(type: type, user : dataForSend1 , pass : dataForSend2)
    let viewProfile = self.storyboard?.instantiateViewController(withIdentifier: "ViewProfile") as! ViewProfile
    self.navigationController?.pushViewController(viewProfile,animated: true)
        }
    }
}

绕过CA可以正常工作，但会延迟。在IBAction中是指先发送Https请求然后转到另一个视图，然后再转到另一个View然后再发送一个https请求。
