I got a second-hand have MacBook Pro and sometimes when I run apps the Mac will start popping every 10-30 minutes. I'm not sure if this is something that happens normally because this is an intel MacBook. If someone knows the answer to my question then please respond Thanks!

I'm developing an application that utilizes WKWebView to display a webpage. My goal is to improve the performance and loading speed of this webpage by intercepting specific API calls and providing pre-stored JSON responses directly from within the app, ensuring the webpage renders instantaneously. The challenge I am encountering is the inability to intercept HTTPS URL schemes directly from WKWebView. Any insights or solutions from the community on how to effectively manage and overwrite these particular network requests would be greatly appreciated.

Hi, I had been working on an extension without any issues, running it from Xcode and debugging locally in Safari. However, without making any code changes, and after uninstalling the extension, it stopped appearing in Safari after building for local debugging. Does anyone know what might be happening or how I can clean up the system? Thanks a lot and best regards.

We used declarativeNetRequest.getMatchedRules() to retrieve the blocked URLs. While we do receive a list, we noticed that the URLs captured do not always reflect the ones the content blocker is actively blocking at that moment. However, upon reloading the same page, the correct URLs appear. Screenshots are attached for your reference. First load: After reload:

I'm injecting some javascript into a WKWebview on iOS. At a certain point the web view spits out these warnings into the console and the javascript execution stops. 0x109018c40 - [PID=778] WebProcessProxy::gpuProcessExited: reason=IdleExit 0x109019200 - [PID=779] WebProcessProxy::gpuProcessExited: reason=IdleExit Failed to terminate process: Error Domain=com.apple.extensionKit.errorDomain Code=18 "(null)" UserInfo={NSUnderlyingError=0x303c3c060 {Error Domain=RBSRequestErrorDomain Code=3 "No such process found" UserInfo={NSLocalizedFailureReason=No such process found}}} I can't find any solution for this so am looking if anyone has any idea of what to try. None of the WKWebview delegate functions trigger when this occurs so I can't attempt to reload the webview at this stage

Title: SafariViewService Recurring "Hard Refresh" Issue on iOS 18.0.1 Hello, Many of my app users are experiencing a recurring "hard refresh" issue related to SafariViewService, which appears only on iOS 18.0.1 across various iPhone models. Users on earlier iOS versions are not encountering this problem. Our app relies on SafariViewService, and the logs show an event triggered by an EXC_GUARD exception with a termination reason from LIBXPC, causing the app to stop. Below are key details from the log report: App Version: 4.1.2 (build 4.1.1.0) OS Version: iPhone OS 18.0.1 Exception Type: EXC_GUARD Subtype: GUARD_TYPE_USER Termination Reason: LIBXPC, XPC_EXIT_REASON_FAULT Device Model: iPhone 11 Pro Max Process Path: [Removed] Here’s an excerpt from the logs: ... {"codes":"0x6000000000000007, 0x0000000000000009","reason":9,"message":"namespc 7 reason_code 0x0000000000000009","subtype":"GUARD_TYPE_USER","type":"EXC_GUARD","rawCodes":[Removed],"namespc":7}, "termination" : {"flags":518,"code":9,"namespace":"LIBXPC","indicator":"XPC_EXIT_REASON_FAULT"}, ... I would greatly appreciate any guidance on resolving this issue, particularly if there are known concerns with inter-process communication (LIBXPC) in iOS 18.0.1 or advice on how to manage the EXC_GUARD exception more effectively. Full log details are in the attachment. Thank you for your help!

I am encountering an issue where we are unable to run or launch Safari Driver in our automation tests using macOS. When attempting to run safaridriver -p 8888 from the terminal, we receive the following error message: ERROR: safaridriver could not launch because it is not configured correctly or you need to authenticate. Re-run safaridriver(1) and pass the '--enable' flag to configure and/or authenticate. For more information, consult the safaridriver(1) man page. Despite running sudo safaridriver --enable as an administrator (even as root), the issue persists. I’ve searched through various online forums and GitHub repositories but couldn’t find a working solution.

I’m encountering an issue with CSS not displaying when using WKURLSchemeHandler to load local HTML files. • When I package the app using Xcode 15.3 or above, the CSS styles do not display on iOS 17 or higher. However, on iOS 16.7.1, the CSS displays correctly. • If I use Xcode 15.2 to package the app, the CSS loads and displays correctly on all iOS versions. I am using WKURLSchemeHandler to intercept and load the local HTML files. Is there any known issue or workaround for this?

When user opens a new tab and loads a website, the declarativeNetRequest.getMatchedRules() returns nil and on reloading in the same tab it returns the URLs blocked. Is this an expected behaviour?

What do I need to do with my webpages to enable Safari AI summary functionality? Thanks, David

As of Safari 18, the tabs.executeScript extension API no longer respects the frameId option passed to it, and instead just runs the script in the top frame. Try running an extension with the following contents on a page with an iFrame (chase.com puts its login form in an iFrame for example). content.js console.log("content.js loaded", location.href); // tabs.executeScript test browser.runtime.sendMessage({ type: "tabs.executeScript" }).then(() => { console.log("tabs.executeScript done"); }); // scripting.executeScript test browser.runtime.sendMessage({ type: "scripting.executeScript" }).then(() => { console.log("scripting.executeScript done"); }); background.js browser.runtime.onMessage.addListener((request, sender, sendResponse) => { if (request.type === "tabs.executeScript") { browser.tabs .executeScript(sender.tab.id, { code: 'console.log("THIS IS RUN FROM TABS.EXECUTESCRIPT", location.href);', frameId: sender.frameId, }) .then(sendResponse); } else if (request.type === "scripting.executeScript") { browser.scripting .executeScript({ target: { tabId: sender.tab.id, frameIds: [sender.frameId] }, func: () => { console.log("THIS IS RUN FROM SCRIPTING.EXECUTESCRIPT", location.href); }, }) .then(sendResponse); } }); You'll see that tabs.executeScript runs its contents in the TOP frame, no matter what the target is. Notably, scripting.executeScript DOES respect the frameId. Filed with Feedback ID FB15420092

I want to switch from Apns to standard notificationApi browser notification, but when my website originally used Apns, I switched to standard API and called Notification for message notification. The notification didn't appear. I confirmed that Notification.permission is granted.

Hi, I am developing the Click & Read web add-on for Chromium, Firefox and Safari. We use xcrun safari-web-extension-converter tool to generate the Safari add-on. The build on Xcode had no meaning errors/warnings, until we had to switch to a more up-to-date MacBook (required as deprecated Mac had no support for latest macOS and thus for Xcode compatibility !). So now I build my add-on on an Apple M1 MB Air on Sequoia 15.0 with latest Xcode, but I encounter an error ? or warning ? : NSBundle file:///System/Library/PrivateFrameworks/MetalTools.framework/ principal class is nil because all fallbacks have failed Unable to create bundle at URL ((null)): normalized URL null Unable to create bundle at URL ((null)): normalized URL null Unable to create bundle at URL ((null)): normalized URL null But it doesn't prevent the add-on build to complete as I am able to open it onto Safari. Then, when loading the add-on on a test web page, I get this error on safari console: Error: Invalid call to runtime.connect(). No runtime.onConnect listeners found. BTW, the same add-on Dist works as expected on Chrome or Firefox (on macOS). So it seems the runtime listener runtime.onConnect.addListener isn't initiated on Background script... Thanks for your feedback and help

Hi. I've noticed on both iOS 17 and iPadOS 16 that when an user opens a website in a WKWebview (e.g from Gmail), then requests it to be opened in the external Safari app (through the "compass" icon), their localStorage data is not transferred to the Safari tab. This behaviour breaks web experiences that rely on data being locally stored, e.g auth tokens or user identification data. It effectively stops users from being able to use some websites outside of an in-app context. I am aware of Webkit's tracking prevention mechanisms such as https://webkit.org/tracking-prevention/#partitioned-third-party-localstorage, but I don't think this should apply to this case. Here the user is navigating between two Safari tabs (one internal and one external) on the same domain, exact same URL, by pressing a native Safari webview icon. There is no third-party cross-domain tracking happening. Is this a bug or intended behaviour?

Hi, I am automating an ios AAP with Appium - 2.11.5 xcuitest - 7.1.0 ios - 17.5 I am working on a browser base application and a scenario where in a new pop up/new window is opened.

Hi, I'm building a nextjs app based on of MapkitJS. I tried to pass a new value to cameraZoomRange like the code below. As long as I put in this part map.cameraZoomRange, the error shows up. Not sure it's my fault, or the bug of MapkitJS. const map = new window.mapkit.Map(element, { colorScheme: mqMatchLightTheme ? window.mapkit.Map.ColorSchemes.Light : window.mapkit.Map.ColorSchemes.Dark, showsCompass: window.mapkit.FeatureVisibility.Hidden, showsMapTypeControl: false, showsZoomControl: false, showsUserLocation: true, tracksUserLocation: true, isRotationEnabled: true, isZoomEnabled: true, }); map.cameraZoomRange = new window.mapkit.CameraZoomRange({ minCameraDistance: 14, maxCameraDistance: Infinity, });

Hi, I’m seeking information about the HLS protocol version supported in Safari on macOS. The official documentation only provides details about iOS support. Is there an official document that addresses this? Best regards
