Our service includes the Apple web login feature to support "Sign in with Apple" on iOS 12. However, at some point, an error started occurring on the Apple login page in iOS 12, preventing users from proceeding further. Upon checking the Web Inspector console, we found the following error: Failed to load resource: the server responded with a status of 503 (Service Temporarily Unavailable) Please help us resolve this issue so that users can continue using "Sign in with Apple" on iOS 12.

"The Referer header allows a server to identify referring pages that people are visiting from or where requested resources are being used. " This header is never forwarded to server when the user is browsing the website in a WebView. This is properly maintained by other browsers but not in-app. How do I include it?

Hello all, As you may know, the company ProofPoint is an Apple partner, and is engaged (I think) to reduce misuse of icloud emails. We have two servers solely set up for our web-app, which is a specialised forum for apartment owners. The new servers were established about the same time, with the same provider, with clean new IP addresses - and as mentioned above, are only used for this web-app. During a testing phase a YEAR ago, we became aware that our in-house icloud emails weren't receiving notifications via the app, and further investigations revealed that the cause was that ProofPoint had placed a block on that server's IP. We immediately, via their website form initiated a Support Ticket, which, the site indicated was lodged, BUT we have never received any response to that Ticket, nor have we received any response to four subsequent Tickets we initiated - nothing. In over a year!! Yesterday, we contacted Apple support, but the devices area of support is the main section and they said it wasn't an issue they could assist with. Some relevant matters: SPF: DKIM: DMARC: are, I believe all configured correctly (and Gmail gives a PASS to all of them). The IP is not blacklisted by any list we are aware of. Our other server's IP isn't blocked by ProofPoint. So, literally at wits end, I'm reaching out to the developer subscribers here to see if they have any suggestions for us. We currently are unable to accept any new subscriber that is using an icloud email address, and that's an absurd situation to be in. Surely we don't have to go to the trouble and inconvenience of obtaining a new IP because of this!!! But when we can't get ANY response to the Support Tickets, it's really hard. Thanks

Hi all, With version 18.4 beta, I have a problem with the display of webviews in the app. In particular, the app of my bank has webviews inside it, and as they are not loading, I am unable to access it. Can you help me? Thank you.

I have observed Safari App starts crashing when running with my safari extension. Our Safari extension polls the host app every 60s. The extension receives and completes requests in func beginRequest(with context: NSExtensionContext) (we always call context.completeRequest(...)). The crash is intermittent: beginRequest itself does not throw. Looking for guidance about likely causes. I am attaching the snippet from crash report. Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGKILL) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace RUNNINGBOARD, Code 3490524077 Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x1856f5c34 mach_msg2_trap + 8 1 libsystem_kernel.dylib 0x1857083a0 mach_msg2_internal + 76 2 libsystem_kernel.dylib 0x1856fe764 mach_msg_overwrite + 484 3 libsystem_kernel.dylib 0x1856f5fa8 mach_msg + 24 4 CoreFoundation 0x185822cbc __CFRunLoopServiceMachPort + 160 5 CoreFoundation 0x1858215d8 __CFRunLoopRun + 1208 6 CoreFoundation 0x185820a98 CFRunLoopRunSpecific + 572 7 HIToolbox 0x1912c327c RunCurrentEventLoopInMode + 324 8 HIToolbox 0x1912c64e8 ReceiveNextEventCommon + 676 9 HIToolbox 0x191451484 _BlockUntilNextEventMatchingListInModeWithFilter + 76 10 AppKit 0x189745a34 _DPSNextEvent + 684 11 AppKit 0x18a0e4940 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 688 12 Safari 0x1b801cce4 -[BrowserApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 228 13 AppKit 0x189738be4 -[NSApplication run] + 480 14 AppKit 0x18970f2dc NSApplicationMain + 880 15 Safari 0x1b83dd0b0 SafariMain + 468 16 dyld 0x185396b98 start + 6076

//Is my post method correct because google and claude are telling me I must use content type for the json and use .setvalue.

Can someone please help me: I do not have the brain space (85yo) to figure out an Apple Script or Java Script app to do this simple task. I have spent a few hours each day, over several days, and have made zero progress on such an apparently simple task. I wish to create an Automator App for the macOS Safari browser that will schedule (via a Calendar Event) the download of the 48hr data behind the hourly Fuel Mix Plot Data from the AEMO Web Site, every Monday, Wednesday, Friday and Sunday. Here is the link to the AEMO web site: AEMO, Energy Systems, Electricity, National Electricity Market (NEM), Data (NEM),Data Dashboard https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem The 48 hour hourly Fuel Mix data is found by selecting the "Fuel Mix" button (which by default will display the NEM Current Trend). The 48 hour trend is displayed by tapping on the small "Current" pulldown menu, and selecting "48 hrs". The 48hr Data is down loaded by selecting the small circular button just to the right of the pulldown menu. a) AEMO Web Site: https://www.aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem b) Main Menu, and underlying html, c) Fuel Mix menu, Pulldown list, DownLoad button, and underlying html, I am familiar with C++ and have built Xcode Apps, and used Excel Macros extensively in the past. Thank you. Robert.

Hello, I'm using Safari 18.2 on Sonoma 14.6.1. I was using the Developer Tools to do a Local Request Override in the Source tab for a CSS file that had a changing query string. I thought I had a good regular expression to catch all variants, but apparently it was too generic and possibly wrong, and made both Source and Network tabs no longer work in my Safari. The regular expression I entered for the Local Request Override was: //build/style.css(?.*)?$ Now my dev tools is broken to the extent that the Source and Network tabs no longer work. The slide-out panel on Source that shows Breakpoints, LocalOverrides, etc no longer shows. The toggle for it does, but does nothing now. UI in general looks a little wack on both tabs. So, since I can't turn off the Local Request Override, I've been trying to locate where Safari may have stored it to manually delete it. Not having a lot of luck on that front. It seems to me that Safari was unable to escape my regular expression correctly and it then causes additional issue. Just a guess though. Any advice or help in getting Safari Source & Network working again / manual removal of the LocalOverride would be greatly appreciated. I'm fluent in OSX and Linux, but grep was not much help surfacing anything that worked. Thanks in Advance, possibly a Safari bug as well.

I’m encountering an issue with a Safari extension bundled with our main application (F-Secure). The extension is not appearing consistently in Safari settings on a customer’s iPad running iOS 18.3. Below are the details of the issue: Issue Description The Safari extension is bundled with the main app (F-Secure). After installing the app, the extension should automatically appear in Settings > Safari > Extensions, where the user can enable it. On the customer’s iPad, the extension is missing from the Safari settings. It briefly appeared once but then disappeared again.

Hello, We’ve been using the CesiumJS WebGL library for several years, both on our website and within embedded WebViews in our iOS application. Since upgrading to iOS versions 18.2 and 18.3, we’ve started receiving numerous user complaints regarding application crashes on various iPad and iPhone models when loading CesiumJS. The crashes occur as soon as the 3D view initializes, and the error consistently reported is: "WebGL context lost" This issue appears to be a WebGL-related crash potentially triggered by GPU memory handling or allocation limits. However, we are not detecting any abnormal memory consumption prior to the crash, and the same setup works perfect on older iOS versions and on all Android devices and versions. Steps to Reproduce: Open: https://www.flightradar24.com/30.47,-94.84/8 Click on any aircraft icon on the map. In the aircraft details panel at the bottom, click on the “3D view” tab. On iOS 18.2 or 18.3, the page will crash shortly after initializing CesiumJS WebGL. Affected Devices: This issue is occurring across a wide range of devices, including: iPad 9th Generation iPad Pro (11-inch, 2nd Gen) iPhone SE (2020 and 2022) iPhone 11, 11 Pro iPhone XR iPhone Mini All of the above are running iOS 18.2 or 18.3. The problem does not occur on Android or previous iOS versions. Request: Has anyone else encountered similar issues with WebGL context loss after upgrading to iOS 18.2 or 18.3? Are there any known changes in memory limits or WebGL behavior in these recent iOS updates? We’d appreciate any insight or suggestions on workarounds or potential fixes. Thank you!

Hello, In iOS 26 beta, we are seeing an unexpected behavior when using SwiftUI WebView (or a custom WKWebView via UIViewRepresentable). When an alert is presented above the WebView, the WebView immediately reloads to its initial page. The alert itself also disappears instantly, making it impossible for the user to interact with it. This issue occurs both with the new SwiftUI WebView / WebPage API and with a wrapped WKWebView. The problem was not present in previous iOS versions (iOS 17/18). Steps to reproduce: Create a SwiftUI view with a WebView (pointing to any URL). Add a toolbar button that toggles a SwiftUI alert. Run the app on iOS 26 beta. Tap the button to trigger the alert. Expected behavior: The WebView should remain as-is, and the alert should stay visible until the user dismisses it. Actual behavior: As soon as the alert appears, the WebView reloads and resets to the initial page. The alert disappears immediately. Minimal Example: struct ContentView: View { @State private var showAlert = false var body: some View { NavigationStack { WebView(URL(string: "https://apple.com")!) .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Close") { showAlert = true } } } .alert("Confirm close?", isPresented: $showAlert) { Button("Cancel", role: .cancel) {} Button("Close", role: .destructive) {} } } } } I'm using Xcode Version 26.0 beta 7 Thanks for your help.

We have written a PAC script that blocklists certain domains and whitelists others. We went to Settings > Network > Wi-Fi (the network we are using), then clicked on Details, and under Proxies, we added the PAC file URL in the Automatic Proxy Configuration section. We tried hosting the PAC file both on localhost and on a separate HTTP server. After saving the settings, we tested several URLs. The blocking and allowing behavior works correctly in all browsers except Safari. Below is the PAC script we are using for your reference. The script works as expected in browsers other than Safari. This is how the PAC script URL looks: http://localhost:31290/proxy.pac function FindProxyForURL(url, host) { var blacklist = new Set(["facebook.com", "deepseek.com"]); var b_list = [...blacklist]; for (let i = 0; i < b_list.length; i++) { let ele = b_list[i] + "*"; if (shExpMatch(host, ele) || shExpMatch(url, ele)) { return "PROXY localhost:8086"; } } if (isIPBlocked(whitelist_subnet, hostIP)) { return "PROXY localhost:8087"; } if (isIPBlocked(blacklist_subnet, hostIP)) { return "PROXY localhost:8086"; } return "PROXY localhost:8080"; }

Subject: iOS 26 WKWebView: Remote Pages Become Unresponsive After Loading Local HTML Files Description We're experiencing a critical issue with WKWebView in a React Native 0.64.3 application where remote web pages become completely unresponsive after loading local HTML files in iOS 26. It works well before iOS26. Environment: React Native 0.64.3 iOS 26.0 Xcode 26.0.1 Using custom WKWebView implementations in Native modules Problem Details App loads local HTML files using loadFileURL:allowingReadAccessToURL: Later, when loading remote pages via loadRequest:, the remote pages load successfully but become unresponsive to user interactions This occurs even when using different WKWebView instances The issue is reproducible 100% of the time once a local file has been loaded Restarting the app and loading remote pages directly works fine Code Example: // Loading local file (works fine) [self.webView loadFileURL:localFileURL allowingReadAccessToURL:accessURL]; // Later, loading remote page (loads but becomes unresponsive) NSURLRequest *request = [NSURLRequest requestWithURL:remoteURL]; [self.webView loadRequest:request]; What We've Tried: Using different WKWebView instances for local vs remote content Comprehensive cleanup in dealloc (removing all user scripts and message handlers) Loading blank HTML before switching to remote content Using shared WKProcessPool (understanding its limitations in iOS 15+) Ensuring proper decisionHandler management in navigation delegates Resetting WKWebView configuration settings Clearing cookies and cache between loads Using loadFileRequest:allowingReadAccessToURL: instead of loadFileURL: Key Observations: The remote page renders correctly and network requests complete No JavaScript errors in console The view hierarchy appears normal in Debug View Hierarchy Touch events seem to be delivered but not processed by the web content Questions: Has Apple introduced new security restrictions in iOS 26 that affect the transition from file:// URLs to http:// URLs? Are there specific WKWebView configuration changes required for React Native applications in iOS 26? Could this be related to the React Native bridge or JavaScript context persistence? Any insights or workarounds would be greatly appreciated, as this is blocking our iOS 26 compatibility.

I'm building a macOS Google Chrome extension. I need to be able to send messages from the Chrome extension to the macOS app What's the set up flow? I've heard about native messaging, but I struggle to implement it. I've heard about XPC, but not sure JS can send messages to a macOS XPC service.

How can i add Authorization header to a wkwebview. I checked https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 which says Authorization header is a reserved http header and shouldn’t be set. I want to set it when requesting a url in wkwebview for authentication purpose?

We have a JavaScript api that queries our Secure Browser to get the network information – signal strength, network name, plugged in/wifi. Everything worked fine through the Tahoe betas, still does. Now we are getting on the network name and this is breaking our UI. Was this an intentional change or a bug? The other two properties still appear to be working. And it works in all lower MacOS versions. We are currently obtaining it through AppleScript try   set ssid to do shell script "system_profiler SPAirPortDataType | awk '/Current Network Information:/ {getline; sub(/^ +/, ""); sub(/:$/, ""); print}'"   if ssid is equal to "" then     return "Not connected to any Wi-Fi network."   else     return ssid   end if on error errMsg   return "Error: " & errMsg end try

Whenever I make a safari view controller on XCode26 Beta 5, there appears to be a blurry white overlay overtop the controller. This worked fine in XCode26 Beta 2, with no code differences. Anyone have any suggestions?

I recently updated my iPhone 12 to iOS 26. It seems there is a bug rendering Safari unable to "add to home screen" any website. Clicking the button displays a blank modal with Add button greyed out.

Since Safari requires a macOS app as a container for Web Extensions, is there a way to establish native messaging directly from SafariWebExtensionHandler using stdin/stdout? Or does Safari enforce a different communication mechanism? I’d like to keep the same approach as other browsers. Any guidance on making this work would be appreciated!
