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" +

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)))

}
}
}
private func sendRequest(completion: @escaping (Result<String, Error>) -> Void) {

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!

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.
In my app I am trying to load webview with an URL , I am checking is it loading on main thread also loading webview in main thread using DispatchQueue.main.async {
self.loadRequest()
}
, webview loads successfully, then showing below error app crashes , unable to find the reason.
"*** Assertion failure in -[UIApplication _performAfterCATransactionCommitsWithLegacyRunloopObserverBasedTiming:block:]"
Thanks in advance
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)

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:

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!
I had to close all application vs code xcode simulator and reboot everything and it started working.
Thanks!

I know how to set up a parental gate to keep a child user away from a web portal for parents or guardians. But is it even OK with Apple (or just in general) to open a browser from inside a kids app?
I can think of two ways to do this:
Launch a browser with UIApplication.shared.open(). This takes the user (presumably an adult) out of the app. Will Apple object to this?
Use an in-app browser with WKWebView. (Wrapped in UIViewRepresentable because I'm using SwiftUI.)
Option 2 has some problems with Google SSO, which is a requirement for me. Some details in stackoverflow 2016 and stackoverflow 2019 and gitHub. I can't figure out how to apply the solutions in those posts to the SwiftUI architecture or even the UIViewRepresentable.
So I am trying to control the wkwebview content within my app. When I try the following code>
var backButton: some View {
Button(action: {
webView.goBack()
// Add your back button action here
}, label: {
Image(systemName: "arrow.uturn.backward")
.font(.title)
})
.navigationBarBackButtonHidden(true)
}
I get webView out of scope.
This is how I have webView implimented
struct WebView: UIViewRepresentable {
let url: URL
let preferences = WKPreferences()
let useragent = WKWebViewConfiguration()
func makeUIView(context: Context) -> WKWebView {
@State var webView = WKWebView()
let request = URLRequest(url: url)
useragent.applicationNameForUserAgent = "Version/1.2 LavaRock/1.2"
useragent.allowsAirPlayForMediaPlayback = true
useragent.allowsInlineMediaPlayback = true
useragent.allowsPictureInPictureMediaPlayback = true
//
preferences.isFraudulentWebsiteWarningEnabled = true
preferences.isSiteSpecificQuirksModeEnabled = true
preferences.isElementFullscreenEnabled = true
webView.allowsBackForwardNavigationGestures = true
// webView.configuration.allowsPictureInPictureMediaPlayback = true
webView.customUserAgent = "Mozilla/5.0 (iPhone; CPU iPhone OS 18_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 Version/1.2 LavaRock/1.2"
webView.load(request)
return webView
}
func updateUIView(_ uiView: WKWebView, context: Context) {
// Handle view updates if needed
}
}
How should create the button?
There is a 'WebCore::CachedResource::removeClient(WebCore::CachedResourceClient&)' crash in iOS 18 version. Could you please tell me if there are any changes to the WebView regarding this crash and how to debug it?
