Is there a way to detect if the user has tapped on "Turn Off Content Blockers" option on safari in ios or get a callback from the same?

Hello! I've been maintaining a Cordova-based calling application for years. Cordova uses a webview to show the user interface and has a bridge for calling native iOS API from JavaScript. The application uses CallKit and VoIP push notifications to handle the calling functionality. Before the iOS 17.5 update, calling worked relatively stable. However, starting from this version and on, Safari instantly force-closes all open websocket connections when the "Answer" button on the calling UI is hit. So, basically, the call ends right after it answers, because in our case websockets are crucial for the SIP negotiation process. Firstly, I inspected the Safari console, and there is a new red error saying: WebSocket connection to 'wss://home.thirdlane.com/wss' failed: The operation couldn’t be completed. Software caused connection abort. Secondly, I checked the Xcode logs, and there are several warnings saying Invalidating grant <invalid NS/CF object> failed every time the call is answered. And, I'm afraid this is all that I have to cling to. I managed to mitigate the effect by connecting the websockets only when the call is answered and the application is focused. However, this approach has its own drawbacks and doesn't solve all the problematic cases. I must mention that the behavior has slightly improved in iOS 17.6 – now the websockets are cut after the "Answer" button hit whereas in 17.5.1 they were cut in ~3 seconds after the VoIP push regardless of whether the answer was made. This looks like a Safari/WebView bug to me and I would like bring it to the Apple's attention. I've never filed a bug before, so hopefully this is the right place to write. I can provide more logs or vidoes upon request. Thank you!

I have some questions about the behavior of encode. For example, with the following code, when we encode a very large string, the result is an empty array. So if memory allocation fails due to insufficient system memory or other reasons, and the returned Uint8Array is not successfully created, what will we get? An empty array, an exception, or an OOM crash? const encoder = new TextEncoder(); const encoded = encoder.encode(largeText);

We have tested on iPhone 12 Pro and observed that Safari allowed approximately 1.5GB of RAM usage. Page refreshes when trying to allocate more memory. After performing a hard reset and erasing all content, I noticed that Safari allowed approximately 3GB of RAM usage for our webpage. However, after 2-3 days, the maximum allowable RAM usage in Safari decreases to about 1.5GB. Once 1.5GB limit is reached, the system reloads the page. To further investigate, I performed another hard reset on my device, and once again, Safari allowed around 3GB of RAM usage. Additionally, we tested this on iPhone 15 Pro and 15 Pro Max, where the RAM limitation in Safari is consistently around 3GB (page is reloading after reaching 3GB). Could you please clarify why the memory limit fluctuates after hard reset? Is there any specific setting or flag within Safari or iPhone that controls the maximum RAM usage, which could be causing this behavior? I also posted the issue there: https://bugs.webkit.org/show_bug.cgi?id=277848 I would appreciate any guidance or potential solutions to this issue. If this is a known limitation or issue, understanding the root cause would be extremely helpful. Thank you for your attention to this matter.

I am developing a web application with PWA and Vue.js (javascript). I would like to add a Web Push notification function, so I referred to the following site to execute notification permission and received the response result "granted". https://developer.mozilla.org/ja/docs/Web/API/Notification/requestPermission_static I have tried both requestPermission(); and requestPermission(callback). However, in this state, an error occurred when subscribing to pushManager, and push notification registration could not be executed. As a workaround, I found that by changing the notification permission setting from the OS Settings > Notification screen to Off and On, subscribing to pushManager was successful. Is there anything else I need to implement other than calling requestPermission(); or requestPermission(callback) to make it executable without following the workaround steps? In addition, this phenomenon was not occurring around the beginning of June 2024, and it was confirmed that the problem occurred as of August 5th. The confirmed OS and models are as follows. iOS 17.4 Mobile Safari iPad iOS 17.3 Mobile Safari iOS 15.8 Mobile Safari iOS 17.3 Mobile Safari iPad iOS 15.8 Mobile Safari iPad iOS 17.4 Mobile Safari iOS 16.7 Mobile Safari

Hi, I'm experiencing an issue with my Safari extension on iOS 18. When trying to access images using browser.runtime.getURL(), it doesn't work as expected. The same code works on iOS 17 and earlier versions. Here's my manifest file and code snippet. "web_accessible_resources": [ { "resources": [ "html/*.html", "images/*.png", "images/*.gif", "images/*.svg", "json/*.json", "fonts/*.ttf", "css/*.css" ], "matches": [ "<all_urls>" ] }, "images/fs_loading.svg", "images/status_protected.svg", "images/safe_check_icon.svg" ] `var status_ok_svg = browser.runtime.getURL("images/status_protected.svg");` Note: Image all are added in Images folder only

Hello, dear Apple community I have WordPress website: https://fritzboxwelt.de/ I was using Google Chrome to access the website dashboard. For some reason, I shifted from Chrome to Safari, but now I am facing errors when logging in. What should I do now? Is it a website issue or my browser settings are not okay? It will be great to hear from you.

Hello everyone, I am currently developing several Progressive Web Apps (PWAs) and I am wondering if it’s possible to programmatically open an installed PWA on iOS/iPadOS from another app or a link. My goal is to be able to launch an installed PWA directly from an action in another PWA, a web app, or a native app on iOS. For example, I’d like to know if this can be achieved via a deep link, a custom protocol (web+), or any other mechanism available on these platforms. Has anyone successfully implemented this feature or found a workaround to programmatically open an installed PWA on iOS/iPadOS? Thank you very much for your feedback and suggestions!

We have implemented a content blocker using the Safari Web Extension, which can be toggled on or off as needed. However, we've noticed that changes in the Safari browser take effect only after the page is reloaded again. This behaviour has been observed across all simulators as well as on iPhone 8 Plus running iOS 16.7.8. Is this due to a delay in the JS file rules updation on simulator and lower devices?

Unable to create a cookie using WebKit API or manually create a cookie in Safari with SameSite=None on a device using iPadOS 18 beta. In Safari, the None option is still in the drop down as a selection for SameSite which leads me to believe this is a bug. Is this going to be fixed in the release version of iOS 18?

Hello, a very simple question, is there a test domain that is flagged by safari as a fraudulent webpage? one that is just for testing? Thank you.

I have a hybrid mobile app which loads web server screens in its iframe(which is under the WKWebView); an https request is initiated from the mobile app to the web server which returns the html page to be loaded in the iframe. The calls which are initiated from outside the iframe have cookies maintained in their requests, while the ones initiated from inside the iframe(web server page) loose the cookies and do not inherit them in IOS beta 18 while It worked fine in the previous IOS versions. Anybody has infos about this or similar cases?

After iOS 17.4, Passkey Autofill stopped working inside ASWebAuthenticationSession. iOS 17.5 re-enabled users to pick passkeys if they tap "🔑" icon on right bottom of keyboard and opened Safari password manager. However, it still doesn't recommend passkeys on the first view. Even on the latest iOS 18.0 developer beta, the behaviour is not fixed yet.

Hello there, We are having a problem when trying to repdorucir videos with videojs in a webview on devices with iOS older than 17.4. When playing them you see that the player restarts several times until crashing the webview. This are the xcode logs when this happens: 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)}> 0x114029980 - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'WebKit Media Playback' for process with PID=64167, 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)} 0x1140180c0 - [PID=64164] WebProcessProxy::didClose: (web process 0 crash) 0x1140180c0 - [PID=64164] WebProcessProxy::processDidTerminateOrFailedToLaunch: reason=Crash

We have an iOS Safari extension currently distributed via Testflight. I’ve noticed that after an indeterminate period of time (sometimes days, sometimes weeks) our safari extension will stop working and will need to be turned on again from the system general -> safari -> extensions menu. This is occurring on both iPhones and iPads running 17.6.1. Is there any condition that will cause the system to disable a safari extension, requiring the user to reopen iOS settings to re-enable?

Hello! We have been testing the upcoming Safari 18 on macOS 15 Sequoia betas and noticed one inconsistent detail about Safari Web Extensions support compared to other browser which implement Web Extensions (Chrome, Edge, Firefox). Background We have a Safari Web extension which is monitoring navigation events using browser.tabs.onUpdated API. navigation event subscription code sample browser.tabs.onUpdated.addListener((tabId, changeInfo, details) => { onTabUpdated(tabId, changeInfo, details) }); navigation event handling code sample onTabUpdated(tabId, changeInfo, details) { console.log(`onTabUpdated: ${tabId}`, changeInfo, details); // check URL in the tab for safety } }); If the extension detects that the user navigates to an unsafe URL, it redirects the user to a page hosted by the extension. It's an HTML resource from the extension bundle. The extension is using browser.tabs.update API to redirect a specific tab to an internal page. const internalPage = browser.runtime.getURL("popup.html"); browser.tabs.update(tabId, { url: internalPage }); Discovered problem When we use browser.tabs.update API browser.tabs.update(tabId, { url: internalPage }); to redirect the user from an unsafe page, we notice that the redirected tab changes its identifier. We know that is the case because we see another API firing. It's called browser.tabs.onReplaced. We have a similar subscription for those events. When the page is redirected, the onTabReplaced handler is firing and informs us about the tab ID change after the redirect. onTabReplaced(addedTabId, removedTabId) { console.log(`onTabReplaced: ${removedTabId} -> ${addedTabId}`); } This is problematic for us in several ways: The extension keeps track of the tab ID so that when the embedded HTML page is loaded, it can still tell the user about the original URL that was blocked. The behavior observed in Safari 18 breaks current expectations of our code and breaks the functionality of our extension. This behavior is specific to Safari 18. Safari 17 does not behave this way which means that we will need to deploy an update to our Safari extension to mitigate that bug on the upcoming Safari version. Moreover, this behavior is not observed in other browsers which implement Web Extensions standard (Chrome, Edge, Firefox). All these browsers preserve the tab ID after redirect. That is a problem for us as we run the same code in all 4 browsers that we support. This will cause increase of code complexity to cover Safari as an exception out of common rule. Environment Safari version 18.0 (20619.1.26.31.6) and all prior Safari 18 betas. issue does not happen on Safari 17. macOS 15 beta 8 (24A5331b) and all prior macOS 15 betas. issue has been successfully reproduced on macOS 14 with Safari 18 betas which points to the fact that the issue is not exclusive to macOS 15. Safari 18 brings the faulty logic. The issue has been confirmed and reproduced in a sample Xcode prowejt provided by Apple called "Sea Creator". So the issue is not specific to a single extension. Feedback case FB14975378. It contains sample code, the full Xcode project, screenshots and sysdiagnose. Any advice or assistance is highly appreciated!

Flutter web view- I am downloading assets from server and using that assets to create html file to load on web view. I downloaded them to the local document directory on the device. From there I can load the HTML files in a webview using the file:// schema, with the benefit that images, css etc. that are referenced in the HTML are loaded as well. This works fine in Android (simulator and real device) as well as in an iOS simulator. But on an iOS device the flutter webview fails to load assets , images & css files with a relative URL from local directory. This is strange as the iOS simulator should behave the same in that case (as it is not really a hardware related issue). Help me out from this issue.

Hi everyone, I’m working on an iOS app using WKWebView, and I have a specific use case involving cross-origin iframes and form autofill. I’m wondering if it’s possible to programmatically fill input elements, such as credit card numbers, within a cross-origin iframe loaded in a WKWebView. I understand that due to the Same-Origin Policy, direct DOM manipulation of cross-origin iframes is restricted. However, I’m curious if there are any methods or workarounds that might allow me to achieve this, specifically within the context of WKWebView. Thanks.

I am using two iPhone11 devices, having iOS v17.6.1 for automation testing using Seleniumv4.X-Appium v2.x. Today I updated the mac to Sequoia15 version which updated the XCode to v16. Just after this update, I could not able to run the previously running automation script. The console message is "org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: Unable to launch WebDriverAgent. Original error: xcodebuild failed with code 70. This usually indicates an issue with the local Xcode setup or WebDriverAgent project configuration or the driver-to-platform version mismatch."
