如何解决complementHandler在xcode中未称为错误

Question

我使用此以下功能来通过URLSessionDelegate在xcode中执行手动服务器身份验证

  func webView(_ webView: WKWebView, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
        func urlSession(_ session: URLSession, didReceive challenge: URLAuthenticationChallenge, completionHandler: @escaping (URLSession.AuthChallengeDisposition, URLCredential?) -> Void) {
            #if DEBUG
            if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust {
                if challenge.protectionSpace.host == "localhost" {
                    // At this point you can prevent a domain that is pretending to be a trusted domain by challenging the user to present some credentials or a security mechanism for authentication.
                    if let serverTrust = challenge.protectionSpace.serverTrust {
                        let credential = URLCredential(trust: serverTrust)
                        completionHandler(URLSession.AuthChallengeDisposition.useCredential, credential)
                    }
                }
            }

                      #endif
        }
    }

但仍然收到此错误=>由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'未将完成处理程序传递给-[health.ViewController webView：didReceiveAuthenticationChallenge：completionHandler：]。如果有人知道如何解决此问题，请告诉我
