PWA pre-caching issue in devices.
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.

Simulator 18.4 Webview CORS issues
I have a very specific issue that happens only on iOS Simulator version 18.4. It does NOT happen when I run my app on a real iOS 18.4 device through Testflight. My app displays a WebView (courtesy of Capacitor, url scheme capacitor://). Inside that Webview I'm using Firebase JS API (11.2.0) and calling signInWithEmailAndPassword, which works well in all other contexts, i.e. browser, Android webview, iOS webview in all other Simulator versions, and on real devices. Only when running in Simulator 18.4, I get a failed network request: cannot parse response Fetch API cannot load https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?... due to access control checks. Failed to load resource: cannot parse reponse error: FirebaseError: (auth/network-request-failed) Everything is working correctly for both: Capacitor app webview installed on a real 18.4 device with Testflight Safari (non-webview) in the 18.4 Simulator The issue is severe for us, because we are unable to develop our app and test it in the simulator on 18.4 Simulator before pushing it through Testflight internal release. Request headers on the failed request (no response status or headers available). Request Accept: / Content-Type: application/json Origin: capacitor://localhost Sec-Fetch-Dest: empty Sec-Fetch-Mode: cors Sec-Fetch-Site: cross-site User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 18_4 like Mac OS X) - AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 X-Client-Version: Mobile/JsCore/11.2.0/FirebaseCore-web X-Firebase-Client: (...)

Css fieldset/legend with flex and float bug
When I want legend inside the filedset, not on the border as default browsers design, I set float: left to the legend. It works in every modern browser - Safari too. The problem is when the filedset itself is set to display: flex. Float propertie of the legend is ignored. In other browsers this approach works fine and the float stays and the legend is inside of the fieldset as we expect.

Why does ReactPlayer fail to play videos at 3x speed only on iOS Safari?
I'm encountering an issue with ReactPlayer where videos fail to play when the playback rate is set to 3x, but this problem only occurs on iOS. The same functionality works perfectly fine on Android devices and desktop browsers like Chrome and Firefox. Here are the details of my setup: ReactPlayer version: 2.16.0 Video format: [MP4, hls ] Tested devices: iPhone 13 Expected behavior: Videos should play smoothly at 3x speed. Actual behavior: Videos fail to load or play when playbackRate is set to 3.0. I've read that iOS Safari might have limitations regarding playback rate due to performance or energy efficiency, but I couldn't find any official documentation to confirm this. If anyone has faced a similar issue or knows the root cause (or a workaround), I'd really appreciate your insights. Additionally, if there are official resources or documentation about playback rate limitations on iOS Safari, please share them. Thanks in advance for your help!

Issue with Safari and webserver with unencrypted HTTP traffic
We seem to be having an issue with a webservice here which is used within our network and IOS Safari. For the service to work , we need to access it with an unencrypted HTTP API call, which acts as a trigger. The server does not respond to HTTPS requests. (the HTTP API call does not contain any data that is privacy sensitive or that can be abused) Since recently the service does not seem to work anymore properly, but this only happens with Safari and IOS. With all other browsers the service is still working normally, only with Safarai it fails. No matter what I do in the settings of the phone, the Safar browser seems to stop immediately after the HTTP request. What is going on here ?? The issue seems to occur only when you don't have an iCloud+ account. With an iCloud+ account I get the same issue when you switch Apple Private Relay on, but that make sense. When I have Apple Private Relay switched off, there is no issue.

Parse error in WebAssembly code only in Safari
I have compiled some Java code to WebAssembly via TeaVM and wrapped it in a PWA. The resulting code runs nicely in Firefox and Chrome but throws an exception in Safari. CompileError: WebAssembly.Module doesn't parse at byte 1657: invalid extended GC op 24, in function at index 2251 Can anybody tell me what's wrong with that code? I mean it can't be so bad if Firefox and Chrome can parse and run it without problems. I am using the most recent versions of all browsers and the offending code can be found here: Run the demo via: https://mpmediasoft.de/demos/Emmentaler/Emmentaler-Demo-TeaVM-Wasm/index.html The offending wasm file is: https://mpmediasoft.de/demos/Emmentaler/Emmentaler-Demo-TeaVM-Wasm/tvw/ModelBridgeTeaVM.wasm With Safari the demo just shows some empty space instead of a complex polygon. You can see the error in the javascript console of Safari.

Issue with SFSafariViewController Not Always Detecting Redirect After Stripe Payment
I am using SFSafariViewController to process payments via a Stripe checkout URL. Once the payment is completed, the user is redirected to a success URL. I have also added associated domains for deep linking. Below is my implementation: func presentCheckout(url: String) { showProgressHUD() let checkoutURL = URL(string: url)! safariVC = SFSafariViewController(url: checkoutURL) safariVC.delegate = self self.present(safariVC, animated: true) } // Delegate method implementations func safariViewControllerDidFinish(_ controller: SFSafariViewController) { print("SafariViewController dismissed") // Handle dismissal } func safariViewController(_ controller: SFSafariViewController, initialLoadDidRedirectTo URL: URL) { print(URL.absoluteString) if URL.absoluteString.contains("xsworld/payment/stripe/checkout/success") { controller.dismiss(animated: true) { if URL.absoluteString.contains("/v1/resources/xsworld/payment/stripe/checkout") { NotificationCenter.default.post( name: Notification.Name("StripePaymentStatus"), object: nil, userInfo: ["url": URL] ) } } } else if URL.absoluteString.contains("xsworld/payment/stripe/checkout/cancel") { // Handle failure NotificationCenter.default.post( name: Notification.Name("StripePaymentStatus"), object: nil, userInfo: ["url": URL] ) } } func safariViewController(_ controller: SFSafariViewController, didCompleteInitialLoad didLoadSuccessfully: Bool) { if didLoadSuccessfully { print("Initial page loaded successfully") } else { print("Initial page load failed") } } Issue: The safariViewController(_:initialLoadDidRedirectTo:) method does not always get called after the payment is completed. Sometimes it works as expected, and sometimes it does not trigger at all. What I’ve Tried: Ensuring the associated domains for deep linking are correctly set up. Checking the success and failure URLs. Debugging to see if the redirect happens but is not detected. What I Need Help With: I want to ensure that the redirection always works after the payment process is completed, whether through deep linking or another reliable approach. How can I guarantee that my app correctly detects and handles the redirect every time? Any guidance or best practices would be greatly appreciated.

SafariDomains Per App VPN Profile Error on iOS 26.0
iOS 26 (from beta 1 to beta 2) We have a VPN app that installs a per-app VPN profile with SafariDomains to filter Safari network traffic. This setup works as expected on iOS versions lower than 26.0. See here more details on SafariDomains: https://developer.apple.com/business/documentation/Configuration-Profile-Reference.pdf On iOS 26, all SafariDomains configured to go through the per-app VPN result in the following error: "Safari can’t open the page. The error was: Unknown Error" Additional Details: Only SafariDomains encounter this error. Other managed apps traffic through the per-app VPN works correctly. Steps to Reproduce: Install the VPN app with a per-app VPN profile. Configure SafariDomains with any URL (e.g., example.com). Open Safari and navigate to the configured URL. Example Configuration: We tested with a simple example by adding only one URL to SafariDomains (example.com). Logs from the console were captured at the moment Safari opened and encountered the error. safari_google2.txt Has anyone else encountered this issue on iOS 26? Any insights or solutions would be greatly appreciated. Thank you!

WKWebview termination due to memory. Adjustable threshold for termination?
Hi, Our company has an application uses the WKWebview to host a lot of content. The content is web based and hosts a lot of charts and metrics. Because of the high content, we've seen the memory of the WebContent hit above 1.25 GB. When that happens, it'll eventually terminate and we have our recovery code to reload the same page Seems like the limit is hidden / internal. Some Apple devs also noted something might be hard coded to be limited as well. Yes, we have our optimizations but we still need to keep our queries, use react, cache, etc... It's just a heavy web application. Request: Can you help us raise that limit? Are there some limitations in Webkit for such a need to terminate? As some devices have much higher RAM than before, we were hoping to be able to dynamically adjust the limit for the wkwebview before it resets. We contacted our internal contacts but they said to post here.

Where can I find the new safari docs?
I am working on some open source documentation genereator tools which should support pwa on apple. I want to check whether some private apple meta tags are still supported like apple-touch-icon, I can only found some archived docs: https://developer.apple.com/library/archive/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html I searched for almost an hour but I can not find anything related to safari and it's behavior in the new documentation. So I want to ask: do I miss anything? or apple is dropping docs for safari?

How to set UserAgent on Safari web driver of selenium
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")

Frontend Does Not Display Password Validation Error (e.g., “Password Cannot Contain Your Name”)
Description When creating an Apple ID via the web form, if the user’s chosen password contains their own name, the server correctly returns an error (e.g., "Password cannot contain your name") in the PUT request's JSON response. However, this error is not shown on the frontend, leaving users unaware of why the form silently fails or stalls. Steps to Reproduce Go to the Apple ID account creation page (https://appleid.apple.com/account). Enter valid account details where the password includes the user's first or last name (e.g., Johnacb2331!l for a user named John Doe). Complete all fields, including phone number verification and captcha. Submit the form and monitor the Network tab in your browser’s DevTools. Observe that the form appears to hang, loop, or silently fail. Open the PUT request to /account — the response JSON will contain the relevant validation error (e.g., “Password cannot contain your name”), but the user is not shown this. Expected Behavior The password validation error (e.g., containing the user’s name) should be immediately displayed in the UI next to the password field to inform the user and allow for correction. Actual Behavior No error is shown in the UI. The form appears to fail silently, leaving the user confused. The actual reason for failure is only visible through browser developer tools in the PUT response payload. Impact This can lead to: User frustration and confusion Increased support overhead Poor UX in a critical flow (account creation) Environment Browser: chrome 136.0.7103.114 Platform: Web (https://appleid.apple.com) Date observed: 31/5/25 Suggested Fix Ensure that password validation messages from backend responses surface in the frontend, especially for common user input issues like including names in passwords. No screenshots as I can not create a new account

Detecting tabs change in Safari App Extension when switching windows inside validateToolbarItem.
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).
