Does webkit have a way to display a smart banner for a home screen web app similar to how a smart banner can be displayed for native apps? I recently noticed (10/23) that Twitter showed a smart banner encouraging Home Screen web app on my Mac running Sonoma. How is this done?

Hi! We are having a hard time with the universal link, help is appreciated! Thanks in advance! The universal link doesn't work after installation for some time. A user has to wait for from 5 to a couple of hours after the app is installed on the device. This has also affected App reviewers since we need the universal link to work for successful login. Each submission will receive a rejection of we cannot login and it will be approved until we kindly ask them to try again. I believe the JSON is delivered to devices by Apple's CDN system and the fact that it works on most devices most of the time should imply that we have a valid apple-app-site-association setup. So I am really confused about the wait time, which is giving us trouble with app review and a bad user experience

Hello, I’m encountering a problem with WebSocket connections in Safari on iOS 18.1 and later when initiated from an iframe. The same implementation works perfectly in other browsers like Chrome but fails in Safari. In Safari, the WebSocket connection fails with error message "WebSocket connection to 'wss://MY_CONNECTION_URL' failed: The internet connection appears to be offline." Has anyone else faced this? Is this a known limitation or bug in Safari? Any workarounds or solutions would be greatly appreciated. Thank you!

I'm using navigator.geolocation.getCurrentPosition to retrieve the users coordinates in a PWA built with Nextjs. getCurrentPosition is called by clicking on a button. If getCurrentPosition is called afterwards, the cached value is returned. On Safari, If I refresh the page, or logout, login and call getCurrentPosition again, the getCurrentPosition error callback is called with an error code 2 - POSITION_UNAVAILABLE. After around five minutes, getCurrentPosition can be called again. Is there some kind of throttling restriction on Safari navigator.geolocation.getCurrentPosition?

I have an endpoint that generates a .ics file. From my mobile app, I open the browser (Safari) and retrieve the .ics file. In Safari, the events are displayed as expected, and I can use the "Add All" button to add them to the calendar. After clicking "Add All," I can select the desired calendar, and the events are successfully added (see screenshots 1 and 2 below). Here’s the initial .ics file response: BEGIN:VCALENDAR VERSION:2.0 CALSCALE:GREGORIAN PRODID:NAME BEGIN:VEVENT DTSTAMP:20250101T195917Z DTSTART:20250102T131600 DTEND:20250102T142500 SUMMARY:My Event 1 UID:unique-uid1 LAST-MODIFIED:20250101T155715Z DESCRIPTION:Description SEQUENCE:1 END:VEVENT BEGIN:VEVENT DTSTAMP:20250101T195917Z DTSTART:20250103T131600 DTEND:20250103T135600 SUMMARY:My Event 2 UID:unique-uid2 LAST-MODIFIED:20250101T155715Z DESCRIPTION:Description SEQUENCE:1 END:VEVENT END:VCALENDAR Later, I updated the .ics file with new event details: BEGIN:VCALENDAR VERSION:2.0 CALSCALE:GREGORIAN PRODID:NAME BEGIN:VEVENT DTSTAMP:20250102T195917Z DTSTART:20250104T131600 DTEND:20250104T142500 SUMMARY:My Event 1 Update UID:unique-uid1 LAST-MODIFIED:20250104T155715Z DESCRIPTION:Description SEQUENCE:2 END:VEVENT BEGIN:VEVENT DTSTAMP:20250102T195917Z DTSTART:20250105T131600 DTEND:20250105T142500 SUMMARY:My Event 2 Update UID:unique-uid2 LAST-MODIFIED:20250102T155715Z DESCRIPTION:Description SEQUENCE:2 END:VEVENT END:VCALENDAR I updated everything according to the iCalendar documentation: UID remained unchanged SEQUENCE has been updated DTSTAMP has been updated LAST-MODIFIED has been updated However it seems like that Safari can't handle updates on events. In the preview we can see the changes, but when I click on "Add All" button, nothing happens. The same behavior is working with other calendars like Outlook (web view) or Google Calendar. My Questions: Is there a property missing from my .ics file that is necessary for iOS Safari to handle updates? Is Safari not designed to handle event updates in this way? Should I consider moving to a subscription-based solution to manage updates more reliably? Any insights or suggestions would be greatly appreciated!

Python version 3.9.1 Selenium version 4.25.0 Safari version 18.1.1 I want to operate Safari using Selenium. For this purpose, I would like to set the UserAgent to iOS and change the viewport. What should I do? The following is the content programmed with the Chrome driver. I would like to achieve this using the Safari driver. import time,os import chromedriver_binary from selenium import webdriver from selenium.webdriver import Safari from selenium.webdriver.safari.options import Options as SafariOptions from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.support.select import Select from selenium.webdriver.chrome import service # selenium 4 from selenium.webdriver.chrome.service import Service as ChromeService from selenium.webdriver.chrome.options import Options from webdriver_manager.chrome import ChromeDriverManager driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()),options = chrome_options) # iPhone 13 params viewport = { "width": 390, "height": 844, "deviceScaleFactor": 3, "mobile": True } #Chrome setting ua = "Mozilla/5.0 (iPhone; CPU iPhone OS 15_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/15.4 Mobile/15E148 Safari/604.1" driver.execute_cdp_cmd("Emulation.setDeviceMetricsOverride", viewport) # change user agent driver.execute_cdp_cmd("Emulation.setUserAgentOverride", {"userAgent": ua}) # ページにアクセス driver.get("https://hogehoge")

Is it a specification that the Service Worker doesn’t work in an internal iframe only when the parent page in a WebView is file://? It works in Mobile Safari under the same conditions, and we couldn’t find any specification that says Service Worker-like behavior doesn’t work with this combination. Step to reproduce: We use Vite to develop the application. For the iframe in Webview, Install vite-plugin-pwa with version ^0.20.5 Add VitePWA({...}) to plugins[] array in vite.config.ts Build and preview the app: npm run build && npm run preview. We open a Webview with file:// and then open the iframe with the URL to which we preview the app (We use ngrok to create the URL). Then we open Safari and inspect the Webview but inside the Developer > Service workers tab doesn’t have a registered service worker. For safari, we do the same step 1-3, We open Safari browser with the URL that we have deployed the app (The same URL we used in the iframe in Webview). We go inside the Developer > Service workers tab and it has a registered service worker. Environment: Simulator: IOS 18.2 Safari: MacOS 15.2 Expectation: Safari and the iframe in Webview should have a registered service worker inside the Developer > Service workers.

Hi there, I have a problem that , after I add website at dock but unable to turn on the website from dock & pop up message also mention that app was damaged. This problem appears after I factory reset my iMac. Please kindly advise. Thank guys.

PWA works perfectly fine in safari browsers in mac but in mobile devices it is not working it just shows, There is no internet connection. found a fix from ios release - https://developer.apple.com/documentation/safari-release-notes/safari-17_2-release-notes but actually it is not solving the issue. in my case even it is not throwing the issue - fix is - Fixed a cache miss bug in DOMCache that triggered service worker fetch errors.

Safari throw a ViewTransition error, called ' Unhandled Promise Rejection: AbortError: Old view transition aborted by new view transition.' however, i don't find how to catch it. i used 'try..catch' or Promise.catch, or catch it in finished/ready/updateCallbackDone Promise. These all don't work.

When a tab goes to sleep, all its resources gets killed. When the user has any interaction it gets active again. However, if there is an audio in the tab, it does not play again even after user interaction. One has to reload/reopen the tab. Is this how it should work? Is there a fix for this?

Hi folks, When doing HLS v6 live streaming with fmp4 chunks we noticed that when the encoder timestamps slightly drift and a #EXT-X-DISCONTINUITY tag is created in either the audio or video playlist (in an ABR setup), the tag is not correctly handled by the player leading to a broken playback containing black screen or no audio (depending on which playlist the tag is printed in). We noticed that this is often true when the number of tags is odd between the playlists (eg. the audio playlist contains 1 tag and the video contains 2 tags will result in a black screen with audio). By using the same "broken" source but using Shaka player instead won't break the playback at all. Are there any possible fix (or upcoming) for AV Player?

Hi there, I use the Clipboard API to create formatted project links with a "copy link" button. This has been really versatile for end users. When they paste into their email, they get a hyperlinked project name that leads to the project, and when they paste into the URL bar, they just get the project URL. It used to be that pasting into Messages on Mac would yield the same behavior as pasting into the URL bar. But recently, Messages started only pasting the inner text of the HTML clipboard, so no URL, just the project name, which isn’t very useful for a copy link function. Is there any way to ensure that Messages pastes the URL while maintaining my formatting options on other surfaces?

I want use the Safari Extension to decorate the window.fetch function, But No matter how I try, I can't get the fetch function to execute correctly. I was going through the documentation: https://developer.apple.com/documentation/safariservices/using-injected-style-sheets-and-scripts and found this sentence: "Injected scripts have an implied namespace — you don’t have to worry about your variable or function names conflicting with those of the website author, nor can a website author call functions in your extension. In other words, injected scripts and scripts that you include in the webpage run in isolated worlds, with no access to each other’s functions or data." Does this mean I can't modify the window object in the content script just like a Chrome extension does with the webpage? BTW, In chrome I use chrome.scripting.executeScript API, and in plasmo I just use world: "MAIN" content script's config to achieved this feature.

When using iOS VoiceOver to navigate a webpage, selecting a element correctly activates the :focus-visible state. However, when VoiceOver moves to a non-button element (such as a or ), the previously focused button retains its :focus-visible state. The focus indicator only updates when VoiceOver moves to another . This behavior can be confusing for screen reader users, as it creates the appearance of multiple elements being focused simultaneously. It also differs from expected keyboard navigation behavior, where focus styles typically update as soon as the user moves to a new interactive element. Is this an intentional VoiceOver behavior, or could this be a bug? If intentional, is there a recommended workaround to ensure correct focus indication when moving between different types of elements? Steps to Reproduce: Enable VoiceOver on an iOS device. Navigate using swipe gestures or explore-by-touch to focus on a . Observe that the button correctly receives the :focus-visible styling. Move to a non-button element (e.g., a with tabindex="0" or an ). Notice that the button still retains its :focus-visible state, even though VoiceOver has moved to a new element. Expected Behavior: The previously focused should lose its :focus-visible state when VoiceOver moves to a different interactive element, just as it does when using keyboard navigation. Actual Behavior: The :focus-visible state remains on the previously focused button unless VoiceOver moves to another . This can create confusion by displaying multiple focus indicators at once. Tested On: iOS 17.7, 18.3.1 iOS Safari iPhone 11 Pro, iPhone 14 Pro Max

I'm posting a question here as I have encountered an issue while seeking help from engineers in the thread. thread773837 If the "Not Secure Connection Warnings" is enabled in Settings > App > Safari, are HTTP connections not allowed under any circumstances? I also posted a question about NSAllowsLocalNetworking not being applied, and I was informed that ATS (App Transport Security) is not related to SFSafariViewController. If that's the case, what feature causes the error "Safari cannot open the page. Error: Failed to navigate to an HTTP URL with HTTPS-only mode enabled"? I am currently working to resolve this issue.

In a project to create a web extension for Safari, using scripting.registerContentScript() API to inject a bunch of scripts into web pages, I needed to manage a dynamic whitelist (i.e., web pages where the scripts should not be injected). Fortunately, scripting.registerContentScripts() gives you the option of defining a list of web pages to be considered as a whitelist, using the excludeMatches parameter in the directive, to represent an array of pages where the script should not be injected. Here just a sample of what I mean: const matches = ['*://*/*']; const excludeMatches = ['*://*.example.com/*']; const directive = { id: 'injected-jstest', js: ['injectedscript.js'], matches: matches, excludeMatches: excludeMatches, persistAcrossSessions: false, runAt: 'document_start' }; await browser.scripting.registerContentScripts([directive]) .catch(reason => { console.log("[SW] >>> inject script error:",reason); }); Of course, the whitelist (the excludeMatches array) is not static, but varies over time according to the needs of the moment. Everything works perfectly in Chromium browsers (Chrome, Edge, ...) and Firefox, but fails miserably in Safari. In fact, Safari seems to completely ignore the excludeMatches parameter and injects the script even where it should not. Has anyone had the same problem and solved it somehow? NOTE : To test the correctness and capabilities of the API in each browser, I created a simple repository on Github with the extension code for Chromium, Firefox and Safari (XCode project).

Hi all, I need to detect if my web application (pure HTML / Javascript) is opened from: Safari from a Mac Safari from an iPad but by asking for the desktop version I tried to check for many properties (including the navigator.useragent) but no difference were visible. Anyone could help me? Thank you

Hi. I'm a developer of Tab Finder (https://apps.apple.com/us/app/tab-finder/id6741719894) My problem is that every time i switch from my first window to a second window, the tabs in the validateToolbarItem() are INcorrect on a first call, but when I switch back from the second window to my main window, the tabs are CORRECT even on a first call. To demonstrate it, i recorded a video: https://youtu.be/RwskzrSJ8u0 To run the same sample extension from the video, you can get the code from this GitHub repo: https://github.com/kopyl/test-tabs-change Its only purpose is to log URLs of an active page of all tabs. The SafariExtensionHandler's code of the sample app is very simple: import SafariServices func printOpenTabsHost(in window: SFSafariWindow) async { let tabs = await window.allTabs() log("Logging tabs for a new window: \(window.hashValue)") for tab in tabs { let page = await tab.activePage() let properties = await page?.properties() let url = properties?.url log(url?.absoluteString ?? "No URL") } } class SafariExtensionViewController: SFSafariExtensionViewController { static let shared = SafariExtensionViewController() } class SafariExtensionHandler: SFSafariExtensionHandler { override func validateToolbarItem(in window: SFSafariWindow, validationHandler: @escaping ((Bool, String) -> Void)) { Task { await printOpenTabsHost(in: window) } validationHandler(true, "") } override func popoverViewController() -> SFSafariExtensionViewController { return SafariExtensionViewController.shared } } Could you please tell if i'm missing something and how to see the actual tabs inside the overridden validateToolbarItem call of the SafariExtensionHandler (or in any other way, I'm okay with any implementation as long as it works).

Hi all! I have been working on a web speech recognition service using the Web Speech API. This service is intended to work on smartphones, primarily Chrome on Android and Safari (or WebKit WebView) on iOS. In my specific use case, I need to set the properties continuous = true and interimResults = true. However, I have noticed that interimResults = true does not always work as expected in WebKit. I understand that this setting should provide fast, native, on-device speech recognition with isFinal = false. However, at times, the recognition becomes throttled and slow, yielding isFinal = true and switching to cloud-based recognition. To confirm whether the recognition is cloud-based, I tested it by disabling the internet connection before starting speech recognition. In some cases, recognition fails entirely, which suggests that requiresOnDeviceRecognition = false is being applied. (Reference: SFSpeechRecognitionRequest.requiresOnDeviceRecognition) I believe this is not the expected behavior when setting interimResults = true. I have researched the native services used by the Web Speech API on iOS devices, and the following links seem relevant: • SFSpeechRecognizer • SFSpeechRecognitionRequest.shouldReportPartialResults • SFSpeechRecognizer.supportsOnDeviceRecognition • Recognizing speech in live audio • Apple Developer Forums Discussion I found that setRequiresOnDeviceRecognition and setShouldReportPartialResults appear to be set correctly, but apparently, they do not work as expected: WebKit Source Code
