Hi, I am developing an app that has a WKWebView and it can open sites like Youtube. The app is sandboxed as it is meant to be uploaded to the mac App Store. It has a feature PiP where we start the native PiP by calling a browser Javascript where we tell the WKWEBView to fire the PiP. It works well when we are running the code from XCODE in Debug scheme. When we run the code from release mode by archiving it or directly from the build folder, the WKWebView is not able to fire the PiP Agent and thus the Native PiP window is not visible, while the site shows that PiP is opened and we can here the sound being played. But PiP window is not visible. I cannot see PiPAgent in activity monitor. Why does it not work from within the release build outside xcode. But when I try to run the build directly from the Finder in builds folder, this PiP feature does not work. Request technical help for this. Thanks!

Dear Apple Support Team, Upon upgrading to iOS 18, I have noticed a marked change in the character spacing of the PingFang font when rendered by WebKit, the web content rendering engine utilized by Safari and other web views in iOS. Specifically, the spacing between characters appears to have increased or altered in a manner that is not consistent with previous iOS versions or with the font's specifications as defined in CSS. This issue has significantly impacted the visual presentation of my web pages, causing a notable deviation from the intended design and potentially affecting user experience. Expected Behavior: The character spacing of PingFang font in WebKit on iOS 18 should maintain consistency with previous versions or adhere strictly to CSS specifications, ensuring a seamless transition for web developers and end-users alike. Request for Assistance: Could you please investigate this issue and confirm if it is a known bug or an intentional change in iOS 18? If it's a bug, could you provide an estimated timeline for a fix or a workaround that we can implement in the meantime? Additionally, any guidance on how to best address this issue in our H5 content, such as alternative font choices or CSS hacks, would be greatly appreciated. Thank you for your attention to this matter. We value the stability and consistency of the WebKit engine and the overall iOS platform, and we look forward to your prompt response and resolution.

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!

In my project, I'm using the WKWebView to display the Google OAuth popup. And after it appears, the JS window.opener is null, and because of that the original window cannot receive an auth token in a callback. This works perfectly fine in iOS 17.0 and earlier, but broken starting from 17.5. I've tested on the 18.0 too - same results the opener is always null no matter what I try. Web Part: <html> <head> <script src="https://accounts.google.com/gsi/client" async></script> </head> <script type="text/javascript"> var global = {}; window.addEventListener("message", function (ev) { console.log("=== Event Listener ===");

console.log(responseToken); let auth = document.getElementById("auth"); auth.textContent = 'Token: ' + responseToken.access_token } }); } return global.client; } function googleOauthClient() { console.log("Trying to login");

How it looks in 17.0 vs 17.5 And ideas about what I might be doing wrong? Or maybe some workaround I can utilize to get the Google OAuth token from the popup. Thanks in advance.

Hello 👋 following questions: I am using a Simulator with VisionOS 2.0 installed on. I am trying to display a remote spatial image. But I cannot display it. I am trying to use the new updates form Webkit (https://webkit.org/blog/15443/news-from-wwdc24-webkit-in-safari-18-beta/#spatial-media) and show the image in a webview. But I cannot make it work. The image is not shown. In the native version I thought about the new quicklook features that would help to display the spatial media. But I think this is also just for local files. Right? I downloaded the file before but no success. Any Ideas how I can display remote spatial images?

I have the same issue. It was reported to Apple in November, 2023. Anyone else see this as a huge issue?

17.5+, when the wkwebview is not visible, the setTimeout function fails to execute when it reaches time.how to fix?

Be warned! When developing your app in Xcode 16 be careful!!! The new SDK has changes that cause builds on Xcode Cloud and other non-beta Xcode to have bugs (EVEN WITH IOS TARGET SET LOWER). This wasted 2 days of development time, but in WKNavigationDelegate, the webView(_:decidePolicyFor:decisionHandler:) method has a new type signature that will ONLY work in the latest SDK. The change was that the decisionHandler now has a @MainActor attribute. This causes Swift to recognize that it "almost" meets an optional requirement and suggests that you change it. If you change it, it will cause builds to not include the optional method.

The application that I'm working on uses WebKit. I'm facing a strange behavior in the app with MACOS14.5, in which errors are being reported only for this OS version.

i can sure the app already hava the camera access, but in the embedded html, i still cannot open the camera. And this HTML page is work at Safari, but cant work on app when the page is embedded in app. there is the error message: DOMException: undefine is not an object (evaluating 'navigator.mediaDevices.getUserMedia') and i also try to use 'navigator.getUserMedia' and 'navigator.mediaDevices.enumerateDevices()', this all dont work.

I'm developing an app where a user can bring a video or content from a WKWebView into an immersive space using SwiftUI attachments on a RealityView. This works just fine, but I'm having some trouble configuring how the audio from the web content should sound in an immersive space. When in windowed mode, content playing sounds just fine and very natural. The spatial audio effect with head tracking is pronounced and adds depth to content with multichannel or Dolby Atmos audio. When I move the same web view into an immersive space however, the audio becomes excessively echoey, as if a large amount of reverb has been put onto the audio. The spatial audio effect is also decreased, and while still there, is no where near as immersive. I've tried the following: Setting all entities in my space to use channel audio, including the web view attachment. for entity in content.entities { entity.channelAudio = ChannelAudioComponent() entity.ambientAudio = nil entity.spatialAudio = nil } Changing the AVAudioSessionSpatialExperience: And I've also tried every soundstage size and anchoring strategy, large works the best, but doesn't remove that reverb. let experience = AVAudioSessionSpatialExperience.headTracked( soundStageSize: .large, anchoringStrategy: .automatic ) try? AVAudioSession.sharedInstance().setIntendedSpatialExperience(experience) I'm also aware of ReverbComponent in visionOS 2 (which I haven't updated to just yet), but ideally I need a way to configure this for visionOS 1 users too. Am I missing something? Surely there's a way for developers to stop the system messing with the audio and applying these effects? A few of my users have complained that the audio sounds considerably worse in my cinema immersive space compared to in a window.

I run the following code on iOS Safari: const stream = await navigator.mediaDevices.getUserMedia({ video: { width: 960, height: 540, }, }); const { width, height } = stream.getVideoTracks()[0].getSettings(); console.log(`${width} * ${height}`); // 960 * 540 setTimeout(() => { const { width, height } = stream.getVideoTracks()[0].getSettings(); console.log(`setTimeout: ${width} * ${height}`); // setTimeout: 540 * 960 }, 600); The width and height of width and height of the video track obtained by synchronously are different from those obtained by asynchronously. This is my test result and userAgent: Can someone help with this issue?

I am converting some old objective-C code deployed on ios 12 to swift in a WKWebView app. Im also developing the app for Mac via MacCatalyst. the issue im experiencing relates to a programmable learning bot that is programmed via block coding and the app facilitates the read and writes back and forth. the audio works via a A2DP connection the user sets manually in their settings, while the actual movement of the robot is controlled via a BLE connection. Currently the code works as intended on MacCatalyst, while on iPhone, the audio being sent back to the robot is very choppy and sometimes doesn't play at all. I apologize for the length of this, but there is a bit to unpack here. First, I know there has been a few threads posted about this issue, this one that seems similar but went unsolved https://forums.developer.apple.com/forums/thread/740354 as well as this one where apple says it is "log noise" https://forums.developer.apple.com/forums/thread/742739 However I just find it hard to believe that this issue seems to be log noise in this case. Mac Catalyst uses a legacy header file for WebKit, and im wondering if that could be part of the issue here.I have enable everything relating to bluetooth in my info plist file as the developer documents say. In my app sandbox for mac catalyst I have the permissions set for bluetooth as well there. Here are snippets of my read and write function func readFunction(session: String){ // Wait if we are still waiting to hear from the robot if self.serialRxBuf == ""{ self.emptyReadCount += 1 } if (!self.serialRxWaiting){ return } // Make sure we are waiting for the correct session if (Int(session) != self.serialRxSession){ return } self.serialRxWaiting = false self.serialRxSession += 1 let buf = self.serialRxBuf self.serialRxBuf = "" print("sending Read: \(buf)") self.MainWebView.evaluateJavaScript(""" if (serialPort.onRead) { serialPort.onRead("\(buf)"); } serialPort.onRead = null; """ ,completionHandler: nil) } // ----- Write function for javascript bluetooth interface ----- func writeFunction(buf: String) -> Bool { emptyReadCount = 0 if((self.blePeripheral == nil) || (self.bleCharacteristic == nil) || self.blePeripheral?.state != .connected){ print("write result: bad state, peripheral, or connection ") // in case we recieve an error that will freeze react side, safely navigate and clear bluetooth information. if MainWebView.canGoBack{ MainWebView.reload() showDisconnectedAlert() self.centralManager = nil // we will just start over next time self.blePeripheral = nil self.bleCharacteristic = nil self.connectACD2Failed() return false } return false } var data = Data() var byteStr = "" for i in stride(from: 0, to: buf.count, by: 2) { let startIndex = buf.index(buf.startIndex, offsetBy: i) let endIndex = buf.index(startIndex, offsetBy: 2) byteStr = String(buf[startIndex..<endIndex]) let byte = UInt8(byteStr, radix: 16)! data.append(byte) } guard let connectedCharacteristic = self.bleCharacteristic else { print("write result: Failure to assign bleCharacteristic") return false } print("sending bleWrite: \(String(describing: data))") self.blePeripheral.writeValue(data, for: connectedCharacteristic, type: .withoutResponse) print("write result: True") return true } Here is what the log looks like when running on mac catalyst, which works just fine sending bleWrite: 20 bytes write result: True sending Read: sending Read: 55AA55AA0B0040469EE6000000000000000000ED sending bleWrite: 20 bytes write result: True sending Read: sending Read: sending Read: 55AA55AA0B0040469EE6000000000000000000ED sending bleWrite: 20 bytes write result: True sending Read: 55AA55AA0B0040469EE6000000000000000000ED sending bleWrite: 20 bytes write result: True sending Read: 55AA55AA0B0040EDCB09000000000000000000ED sending bleWrite: 20 bytes write result: True sending Read: sending Read: 55AA55AA0B00407A7B96000000000000000000ED sending bleWrite: 20 bytes write result: True Error acquiring assertion: <Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)" UserInfo={NSLocalizedFailureReason=(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)}> 0x12c0380e0 - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'WebKit Media Playback' for process with PID=36540, error: Error Domain=RBSServiceErrorDomain Code=1 "(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)" UserInfo={NSLocalizedFailureReason=(originator doesn't have entitlement com.apple.runningboard.assertions.webkit AND originator doesn't have entitlement com.apple.multitasking.systemappassertions)} and here is the log from when we are running the code on iPhone (trying to save space here) I apologize for the length of this post, however submitting a test project to apple developer support just isn't possible with the device thats in use.

After updating iOS, my Cordova app behaves incorrectly after receiving a voip push. When a push notification is received, my application launches CallKit, displays the Native Dialer screen and starts other necessary services. Until 17.5.1 (possibly 17.5) everything worked correctly. All services and sockets were established/ connected and working. After updating iOS to 17.5, the application crashes, and while voice connection is established the app is no longer active. Xcode logs have these error messages: Invalidating grant <invalid NS/CF object> failed Type: Error | Timestamp: 2024-06-20 13:27:44.719601+02:00 | Process: MyApp | Library: WebKit | Subsystem: com.apple.WebKit | Category: ProcessCapabilities | TID: 0x3a4929 Invalidating grant <invalid NS/CF object> failed Type: Error | Timestamp: 2024-06-20 13:27:44.732219+02:00 | Process: MyApp | Library: WebKit | Subsystem: com.apple.WebKit | Category: ProcessCapabilities | TID: 0x3a4929 Invalidating grant <invalid NS/CF object> failed Type: Error | Timestamp: 2024-06-20 13:27:44.733996+02:00 | Process: MyApp | Library: WebKit | Subsystem: com.apple.WebKit | Category: ProcessCapabilities | TID: 0x3a4929 I am using: Cordova iOS: 6.2 iOS 17.5.1 Can anyone please help?

Hello everyone! I have a WKWebView in my swiftui app and would like to enable to "pop root view when selected tab is tapped again" feature, but I have been unable to figure out how to implement this. Here's the basic code: class TabIdentifierModel:ObservableObject { @Published var tabSelection:TabIdentifier { willSet { if newValue == tabSelection { NotificationCenter.default.post(name: .popRootView, object: nil, userInfo: ["tab": newValue.rawValue]) } } } init() { tabSelection = .home } } struct ContentView: View { @AppStorage(AppStorageKeys.enableShorts) var enableShorts = true @StateObject var storeVM = StoreVM() @StateObject var downloadURLManager = DownloadURLManager.shared @State var downloadViewIsOpen = false // ...... @State var tabSelection = TabIdentifierModel() var body: some View { TabView(selection: $tabSelection.tabSelection) { // ...... WebViewWrapper(url: $libraryTabURL) .tabItem { Label { Text("Library") } icon: { Image(systemName: "folder.fill") } }.tag(TabIdentifier.library) // ...... } .environmentObject(tabSelection) } } Tapping on the tab again doesn't seem to set the value again thus the NotificationCenter.default.post is not sent and the web view is not reloaded. Help would be much appreciated! Thanks in advance!
