I have the following html that is opened in a WKWebView.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Popup Window Test</title>
</head>
<body>
<textarea id="myTextarea" cols="5" rows="1">Empty</textarea>
<script>
function openWindow() {
const popup = window.open(
"https://www.apple.com/",
"PopupSample",
"width=400,height=400,dialog=yes,dependent=yes,scrollbars=yes,location=yes"
);
console.log("Popup closed: ", popup.closed);
document.getElementById("myTextarea").value = popup.closed
? "Closed"
: "Open";
const timer = setInterval(() => {
console.log(popup.location.href);
if (popup.closed) {
clearInterval(timer);
console.log("Popup closed: ", popup.closed);
document.getElementById("myTextarea").value = "Closed";
}
}, 1000);
}
</script>
<button onclick="openWindow()">Open Window</button>
</body>
</html>
When I click the button and open page "https://www.apple.com/" in another WKWebView, the javascript code does not work as expected here, the popup object returned from window.open() does not refer to the valid window object, and the closed property is set to true even the new popup window is still alive.
This is a regression since MacOS14.4 updated, I've reported to apple DTS, but they said it's out of their scope.
Does anyone has any clue about this?

[WKWebView dealloc]
WebKit::WebURLSchemeTask::stop() - crash
Hi, I'm trying to implement a type conforming to WKScriptMessageHandlerWithReply while having Swift's strict concurrency checking enabled. It's not been fun.
The protocol contains the following method (there's also one with a callback, but we're in 2024):
func userContentController(
controller: WKUserContentController,
didReceive message: WKScriptMessage
) async -> (Any?, String?)
WKScriptMessage's properties like body must be accessed on the main thread. But since WKScriptMessageHandlerWithReply is not @MainActor, neither can this method be so marked (same for the conforming type).
At the same time WKScriptMessage is not Sendable, so I can't handle it in Task { @MainActor in this method, because that leads to
Capture of 'message' with non-sendable type 'WKScriptMessage' in a `@Sendable` closure
That leaves me with @preconcurrency import - is that the way to go? Should I file a feedback for this or is it somehow working as intended?
Hi Apple Team,
We have a PWA which supports downloading and playback for audio and video content. Downloaded content is stored in IndexedDB in the form of blobs and blob URLs are generated on runtime through which content is played.
We have observed that the blob URLs have stopped working on iOS 17.4.1. They work on iOS 17.4 and iOS 17.3 as well.
This feature is very critical for us as it is the heart of the offline mode of the app.
Thanks!
As part of a university project, we need to be able to display a website on an Apple Watch and log in to a service. Is it possible to get access to the WebKit framework in a watchOS app? We also need to be able to execute JavaScripts in the browser so that the login process works.
Hi. I plan to use a WebView in an iOS app (SWIFT) and this should run a web app with WASM and using IndexedDB for permanent credentials.
I found rumors and information on Apple deleting data in IndexedDB and localStorage after 7 days (see links below). But I found no official information that tells me if this is true for my WebView in my ordinary mobile App (not PWA).
A test cycle over a week to find out is hard to do...
Is there any reliable and clear information on this and am I affected?
Thank you!

I have an HTTP3 relay setup and I'm trying to get WKWebView traffic to use it. The relay has a self-signed certificate for TLS traffic.
When using URLSession to make a call, everything works as expected, but in WKWebView, it doesn't.
Here is how I setup my ProxyConfiguration
let options = NWProtocolTLS.Options()
// sample options to trust any certificate for testing
sec_protocol_options_set_verify_block(options.securityProtocolOptions, { (sec_protocol_metadata, sec_trust, sec_protocol_verify_complete) in
sec_protocol_verify_complete(true)
}, DispatchQueue.global())
let relayServer = ProxyConfiguration.RelayHop(http3RelayEndpoint: relayEndpoint, tlsOptions: options)
let relayConfig = ProxyConfiguration(relayHops: [relayServer])
I connect that to my webview by simply doing the following:
let configuration = WKWebViewConfiguration()
configuration.websiteDataStore = WKWebsiteDataStore.nonPersistent()
configuration.websiteDataStore.proxyConfigurations = [relayConfig]
let webView = WKWebView(frame: .zero, configuration: configuration)
The sec_protocol_options_set_verify_block is never called for the WKWebView (it is when I use URLSession)
I get the following error in XCode
[pageProxyID=7, webPageID=8, PID=73105] WebPageProxy::didFailProvisionalLoadForFrame: frameID=1, isMainFrame=1, domain=NSURLErrorDomain, code=-1202, isMainFrame=1, willInternallyHandleFailure=0
Is there some API I am missing to get the webview to do custom TLS validation with an HTTP3 relay?
Hello
We received frequent crashes for the webkit on 17.4.1. We checked the code as well nothing got changed from our side. I tried to reproduce it but unable to do so. Can anybody advice on this.
Below is the stack trace for same
Please help to check. Thanks in advance
I would like to specify "Connection: close" for a request that I load in WKWebView - which actually CAN be done by setting the value on the request that is loaded (and it actually works). However, the documentation at https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 states that it shouldn't be used because the URL loading system handles persistent connections for you.
So - my question is how can I indicate to the URL Loading System that I do NOT want to use persistent connections for this particular request? Or - am I safe to just set the header even though it's listed as reserved (because - as mentioned - it does work)?
On ios15, when loading a page, occasionally all resources under a domain name cannot be loaded.
the code like this:
<html><head>
<title>issue page</title>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
</style></head>
<body><div>
<script type="text/javascript" src="https://wx.qq.com/open/js/jweixin-1.6.0.js"></script>

<script type="text/javascript" src="https://statres.ok.com/quickapp/js/qa_router.min.js"></script>
<script type="text/javascript" src="https://wap.xxxx.com/static/webapp/common_res/js/utils.min.js"></script>
</div></html>
This is a simplified page code.
The problem is that the page cannot be loaded. Resources under wx.qq.com and statres.ok.com can be loaded, but all resources under wap.xxxx.com fail to be loaded. (Debugging via safari)
wkwebview did not call back to didFinishNavigation, and the page load progress was stuck at 0.5. And then it didn't go out of time. It just stayed there.
Here are some of the solutions I tried:
1、At first I thought it was a resource problem, but everything worked fine when I copied it to safari. In addition, most of the time in my page is fine, but once this problem occurs, the page will no longer load out until I restart the app.
2、thought is to cache problem, repetition, I added NSURLRequestReloadIgnoringLocalCacheData, also was not used.
3、 I captured the system logs through idevicesyslog and found no obvious anomalies in webkit.
4、When I used wireshark to find the problem, wap.xxxx.com did not even initiate dns requests, as if the browser ignored the resource.（Normally, I caught the dns request for this page）
Please help me divergent ideas, thank you!

I am currently developing an iOS app that needs to embed a third-party website. On this website, the best view is achieved in the standard Safari app by pressing the 'Aa' button on the left side of the address bar and setting the zoom to 50%.
I want to replicate this 50% scaling in WKWebView, but I'm not sure how to accomplish it.
I've tried using
webView.pageZoom = 0.5
and setting
webView.scrollView.minimumZoomScale = 0.5
webView.scrollView.maximumZoomScale = 0.5
but it doesn't display the same way as it does in Safari.
How can I achieve the same scaling effect in WKWebView?
in demo ,load index.html into WKWebView, when i click file button, the camera page present and then dismiss quickly

I am trying to sync up the selected tab bar item once a user presses back and navigates back in the web wrapper iOS app.
Here is how the app works: When a user logs in, they are presented with the Home Screen. To navigate, the select a tab item on the tab bar. This tells webkit to redirect to that URL and then that webpage is shown in the app (wrapped). A back button also appears. When a user presses the back button, the webView.goBack() method sends the user back on in the webView.backForwardList. What happens then is that the user is now on the previous page, however the tab bar has not updated. In other words, the user is back on the first tab but the second tab is highlighted.
I tried fixing this by telling the tab bar controller what item to select, however this creates a state malfunction because it also tells the webView to navigate to that url again, so in fact this means that the user isn't going back through web history, but actually is going forward while simulating going back.
I need to be able to highlight the tab bar items that sync up with the page that we have gone back to without selecting it. Does anyone have an idea for how to manually highlight or select a tab bar item without actually navigating to that tab bar item?
Thank you!
Hi Everyone,
I scanned my iPhone SE 3d generation with the iMazing app developed by Amnesty International, and after the scan it detected 3 Warnings on my iphone.
Any of you is able to understand what´s the issue is about? That would be great help!
Following the 3 Warnings:
Warning - Database Query Error - WebKit Observations - 'AppDomain-com.apple.tips/Library/WebKit/WebsiteData/ResourceLoadStatistics/observations.db' cannot be parsed (no such table: ObservedDomains).
Warning - Database Query Error - InteractionC - 'HomeDomain/Library/CoreDuet/People/interactionC.db' cannot be parsed (no such table: ZINTERACTIONS).

not working html embed code
I modified an InputMethodKit example (fairly recent one from github, compiled fine and worked as expected on my machine as it was) to create a window with a WKWebView and the window doesn't load. I know that loadView is getting called, but the window never appears after calling showWindow on the window controller and there is a mysterious error in the console:
bootstrap_check_in(): (os/kern) unknown error code (44c)
From googling this it seems App Sandbox related, but I think I have everything set up correctly (App Sandbox on with outgoing connections allowed)
Totally stumped, any help or ideas would be appreciated
Here's the relevant code:
View controller
import Foundation
import WebKit
import AppKit
class InputWindowViewController: NSViewController, WKUIDelegate {
var webView: WKWebView!
override func loadView() {
NSLog("LoadView")
webView = WKWebView()
self.view = webView
webView.uiDelegate = self
webView.needsDisplay = true
}
override func viewDidLoad() {
super.viewDidLoad()
webView.load(URLRequest(url: URL(string:"https://www.apple.com")!))
}
}
Window controller
import AppKit
import Foundation
import WebKit
class InputWindowController: NSWindowController {
var controller: InputWindowViewController?
override init(window: NSWindow?) {
controller = nil
super.init(window: window)
}
override func loadWindow() {
self.window = NSWindow(contentViewController: controller!)
}
required init?(coder: NSCoder) {
controller = nil
super.init(coder: coder)
}
}

override init() {
super.init()
self.delegate = appDelegate
}
required init?(coder: NSCoder) {
// No need for implementation
fatalError("init(coder:) has not been implemented")
}
}
@main
class AppDelegate: NSResponder, NSApplicationDelegate {
var server = IMKServer()
var candidates = IMKCandidates()
var inputWindowController = InputWindowController()
func applicationDidFinishLaunching(_ notification: Notification) {
// Insert code here to initialize your application
server = IMKServer(name: Bundle.main.infoDictionary?["InputMethodConnectionName"] as? String, bundleIdentifier: Bundle.main.bundleIdentifier)
inputWindowController = InputWindowController()
inputWindowController.controller = InputWindowViewController()
inputWindowController.loadWindow()
inputWindowController.showWindow(self)
candidates = IMKCandidates(server: server, panelType: kIMKSingleRowSteppingCandidatePanel, styleType: kIMKMain)
NSLog("tried connection")
}
func applicationWillTerminate(_ notification: Notification) {
// Insert code here to tear down your application
}
}
This code is probably awful in a lot of other ways I don't realize, but I wanted to get a webview window up before I put a bunch of time into this thing
