In Safari, when there are two password fields side-by-side, they are actually asking for different passwords. However, the browser's autofill might automatically fill the second field with the same password as the first, assuming it's a confirmation.

Hello, I am trying to apply ProxyConfiguration on the WebKit webview. I referred to the following sources: https://forums.developer.apple.com/forums/thread/110312 and https://developer.apple.com/videos/play/wwdc2023/10002/ import WebKit class WebKitViewModel: ObservableObject { let webView: WKWebView @Published var urlString: String = "https://example.com" init() { webView = WKWebView(frame: .zero) } func loadUrl() { guard let url = URL(string: urlString) else { return } var request = URLRequest(url: url) let endpoint = NWEndpoint.hostPort(host: "127.0.0.1", port: 9077) let proxyConfig = ProxyConfiguration.init(httpCONNECTProxy: endpoint) let websiteDataStore = WKWebsiteDataStore.default() websiteDataStore.proxyConfigurations = [proxyConfig] webView.configuration.websiteDataStore = websiteDataStore webView.load(request) } } However, this configuration only works for HTTP proxies. When I try to use an HTTPS proxy, it does not work. When I use NWConnection to connect to the proxy, it works successfully: import Foundation import Network public class HTTPProxy { private let proxyHost: NWEndpoint.Host private let proxyPort: NWEndpoint.Port private var connection: NWConnection? public init(proxyHost: String, proxyPort: UInt16) { self.proxyHost = NWEndpoint.Host(proxyHost) self.proxyPort = NWEndpoint.Port(rawValue: proxyPort)! } public func sendHTTPRequest(completion: @escaping (Result<String, Error>) -> Void) { let tlsOptions = NWProtocolTLS.Options() let parameters = NWParameters(tls: tlsOptions) connection = NWConnection(host: proxyHost, port: proxyPort, using: parameters) connection?.stateUpdateHandler = { [weak self] state in switch state { case .ready: self?.sendConnectRequest(completion: completion) case .failed(let error): completion(.failure(error)) default: break } } connection?.start(queue: .global()) } private func sendConnectRequest(completion: @escaping (Result<String, Error>) -> Void) { guard let connection = connection else { completion(.failure(NSError(domain: "Connection not available", code: -1, userInfo: nil))) return } let username = "xxxx" let password = "xxxx" let credentials = "\(username):\(password)" guard let credentialsData = credentials.data(using: .utf8) else { print("Error encoding credentials") fatalError() } let base64Credentials = credentialsData.base64EncodedString() let proxyAuthorization = "Basic \(base64Credentials)" let connectString = "CONNECT api.ipify.org:80 HTTP/1.1\r\n" + "Host: api.ipify.org:80\r\n" + "Proxy-Authorization: \(proxyAuthorization)\r\n" + "Connection: keep-alive\r\n" + "\r\n" if let connectData = connectString.data(using: .utf8) { connection.send(content: connectData, completion: .contentProcessed { error in if let error = error { completion(.failure(error)) } else { self.receiveConnectResponse(completion: completion) } }) } } private func receiveConnectResponse(completion: @escaping (Result<String, Error>) -> Void) { connection?.receive(minimumIncompleteLength: 1, maximumLength: 65536) { data, context, isComplete, error in if let data = data, let responseString = String(data: data, encoding: .utf8) { if responseString.contains("200 OK") { self.sendRequest(completion: completion) } else { completion(.failure(NSError(domain: "Failed to establish connection", code: -1, userInfo: nil))) } } else if let error = error { completion(.failure(error)) } } } private func sendRequest(completion: @escaping (Result<String, Error>) -> Void) { guard let connection = connection else { completion(.failure(NSError(domain: "Connection not available", code: -1, userInfo: nil))) return } let requestString = "GET /?format=json HTTP/1.1\r\n" + "Host: api.ipify.org\r\n" + // "Proxy-Authorization: Basic xxxxxxxx\r\n" + "Connection: keep-alive\r\n" + "\r\n" print("Sending HTTP request:\n\(requestString)") if let requestData = requestString.data(using: .utf8) { connection.send(content: requestData, completion: .contentProcessed { error in if let error = error { completion(.failure(error)) } else { self.receiveResponse(completion: completion) } }) } } private func receiveResponse(completion: @escaping (Result<String, Error>) -> Void) { connection?.receive(minimumIncompleteLength: 1, maximumLength: 65536) { data, context, isComplete, error in if let data = data, !data.isEmpty { print ("Data: \(data)") if let responseString = String(data: data, encoding: .utf8) { print("Received response:\n\(responseString)") completion(.success(responseString)) } else { completion(.failure(NSError(domain: "Invalid response data", code: -1, userInfo: nil))) } } else if let error = error { completion(.failure(error)) } if isComplete { self.connection?.cancel() self.connection = nil } else { self.receiveResponse(completion: completion) } } } } This approach works for connecting to the proxy, but it does not help with configuring the proxy for WebKit. Could someone please assist me in configuring a proxy for WebKit WebView to work with HTTPS proxies? Thank you!
