Safari Extension Message Passing Unreliable in iOS 18.4.1 and iOS 18.5
Hi everyone, I’m encountering a serious reliability issue with message passing in my Safari extension on iOS 18.4.1 and iOS 18.5 In my extension, I use the standard messaging API where the background script sends a message to the content scrip. The content script is listening using: browser.runtime.onMessage.addListener(handler); This setup has been working reliably in previous versions of iOS, but since updating to iOS 18.4.1 and iOS 18.5, I’ve noticed that messages sent from the background script are not consistently received by the content script. From my logs, I can confirm that: The background script is sending the message. The content script’s listener is not always triggered. There are no errors or exceptions logged in either script. It seems as if browser.runtime.onMessage.addListener is either not getting registered in time or failing silently in some instances. This issue is intermittent and does not occur all the time. Has anyone else experienced similar issues in iOS 18.4.1 and 18.5? Are there any known changes or workarounds for ensuring reliable communication between background and content scripts in this version? Any help or insights would be greatly appreciated. Thanks!

Safari Web Extension background script becomes unresponsive after 30 seconds
I'm experiencing a Safari Web Extension issue where the non-persistant background script seems to crash after 30 seconds even when the content script is messaging it. Here is a minimal-reproducible example. When running in an emulator, the background script will stay responsive forever. However, when running on a physical device, the background script becomes non-responsive after 30 seconds of activity. It never becomes responsive again until I toggle the extensions enable/disable toggle, after which it stays active for 30 seconds and then crashes again.

I want to specify the background color for the header notch and footer indicator area when opening the browser in Safari on iOS 26.
When I open the browser in Safari on iOS 26, I want to specify the background color for the header notch (where the time, battery, etc. are displayed) and the footer indicator area. Specifying the theme color in HTML as shown below did not change anything. <meta name="theme-color" content="#ff0000"> <meta name="theme-color" media="(prefers-color-scheme: light)" content="#ff0000"> <meta name="theme-color" media="(prefers-color-scheme: dark)" content="#ff0000"> The HTML below specifies the background color as green, but is it necessary to specify the background color directly in the body like this? Or is there some kind of metadata, like theme color? <!doctype html> <html lang="ja"> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width,initial-scale=1" /> <meta name="theme-color" content="#ff0000"> <meta name="theme-color" media="(prefers-color-scheme: light)" content="#ff0000"> <meta name="theme-color" media="(prefers-color-scheme: dark)" content="#ff0000"> <title>サンプル</title> </head> <body style="background:#00ff00"> <main> <p>テキスト</p> </main> <div id="overlay" role="dialog" aria-modal="true" data-test-id="health-warning-modal" style=" color:#000000; position:fixed; inset:0; z-index:30000; background:#2563eb; display:grid; /* 初期表示：表示中 */ align-items:center; justify-content:center; overflow-y:auto; " > <div style=" padding:60px 16px; display:flex; flex-direction:column; gap:20px; width:100%; box-sizing:border-box; " > <p style=" font-weight:700; text-align:center; margin-top:20px; font-size:28px; line-height:1.4; " > オーバーレイ </p> </div> </div> </body> </html>

Safari Is Unusable
I have had zero luck anywhere else and it’s at this point infuriating. February 23rd of this year I submitted a ticket in Feedback regarding how Safari for me has been broken. I can’t load any website at all, I have cleared cache, data, you name it. I have reset the phone after doing so and as I type this today on a brand new iPhone 17 Pro Max it still doesn’t work. Every single app that prompts a Safari window to sign in also doesn’t work and crashes just as Safari the app does. Sometimes I get a message that pops up that says “Webkit encountered an internal error” before it crashes. I can’t provide a screen recording or screen shots because Safari just crashes. I genuinely don’t know what to do or where to go for an answer and i’ve submitted seven updates to my open Feedback ticket since February 23rd 2025, spanning months from that original date and yet no change or help has came from it. I am clueless on how to even begin to go about fixing it and agitated because it’s been so long, so many other apps effected by this, even on a brand new device Safari still does not work for me. Any help at all would be greatly appreciated I used to have a 15 Pro Max but now on the 17 Pro Max and throughout the entire time i’ve been on the developer beta. Maybe that is the issue i’m unsure because now i’m just on iOS 26 so I don’t know if it’s just stuck like this forever. Again any help would be appreciated. I have not went physically to Apple yet to get this solved it‘s been a last resort, considering my options I might have to clear time to go. I’ve been using Chrome ever since this issue.

Safari: Sticky element with bottom: 0 does not follow viewport when toolbar hides on scroll
Device: iPhone 15pro, ios26.0 (23A 341) IOS version: 26.0 (23A 341) When using position: sticky; bottom: 0, the div is expected to stick to the bottom of the viewport when the browser toolbar hides while scrolling. However, it stops at the height where the toolbar was, instead of moving down with the disappearing toolbar. In the image below, the red-bordered navigation shows the situation where it does not stick to the bottom. i

Performance of Web View inside of iOS shell
We are working on an internal enterprise iOS application which we need to host a pretty complex web page inside. We have been reading regarding the WKWebView and how it performs inside of iOS shell, but there is no real data on what are the limitation of the WKWebView in terms of memory for the hosted Web Page. Let's say we could measure our iOS app before the WKWebView is launched and after it is launched. We see that the memory consumption of the web page loaded into WKWebView is X mb. How would we know that iOS would allow an app with such webpage loaded into WKWebView and won't terminate the app which the web page is loaded. Is there any documentation regarding on what is the maximum allowed memory for the web page which is hosted inside of WKWebView? And another question, for the Enterprise Developer Program are there any ways to increase the limit of the memory a specific iOS app is allowed to consume before it is terminated from iOS device due to low memory warning from iOS?

Webview In-App Browser Microsoft Login Redirection Not Working
Hello, We received a rejection on one of our IOS applications because we were doing Microsoft MSAL login through the user's browser. The representative recommended that we use Webview to do in-app logins. However when we tried to handle the custom app uri redirection (looking like myapp://auth/), Webview does not seem to send the user back to the application. Does anyone have a fix for this? Thanks!

WKWebView and WebAuthN question
After reading several posts I see that I need to add the "com.apple.developer.web-browser.public-key-credential" capability to my macOS app in order to get it to work. So my noob question is where do I request this capability? Can I as a developer request it or does the Account owner need to request it? Once approved, how do I add it to my app's capabilities? Thanks for your patience

iOS 26 BETA 4 Safari Web Extension disappearing right after install, "extension" is no longer available.
our company created a web safari extension. before iOS 26 (beta) release we would archive our extension and install to our devices no problem. since iOS 26 (beta) (we also tried in beta 4 23A5297m) the extension would archive perfectly but when installing the extension would just not run. its found in settings under safari extension, but when enabled the extension and open safari it will show error message "Ext" is no longer available. to rule out all code issues, we built a new project from scratch with a new bundle id, tried to archive with no problem, but when installed in an iphone 16 with iOS 26 BETA (23A5297m) same error ocurs it installs but when opening safari it will give an error message saying extension is no longer available. attached in the google drive link is a zip file of the new project, a zip file with a succesfull build of the ipa file with enterprise distribute, a video of the entire proccess and the error that the iphone gives. also attached a log file from the iphone that includes the install and the crash of the app. within the logs there is a log saying Error occurred during transaction: The provided identifier "dev.sacal.ext" is invalid. before ios 26 the exact steps worked perfectly. https://drive.google.com/file/d/1PYDOv8IRvRY_ouqiOc0sJdcfh0CHbL72/view?usp=sharing

New IOS Safari CSS Issue with DVH & VH
After updating to the new iOS, in Safari, my overlays and backdrops using 100dvh no longer cover the full screen there's now a gap at the bottom. Switching to 100vh fixes it, but that causes scrolling issues on older Safari versions since 100vh includes extra height. Has anyone else experienced this? What's the recommended fix that works across iOS versions?

WKWebView crashes in SSO App Extension on iOS 26 during loadRequest
We have a SAML-based SSO App Extension that uses WKWebView to load the SAML login request. This implementation has been working correctly on iOS versions prior to 26. However, starting with iOS 26, the extension consistently crashes when calling WKWebView.load(_:). The crash occurs inside WebKit, specifically in: /Library/Caches/com.apple.xbs/Sources/WebKit/Source/WebKit/UIProcess/WebsiteData/WebsiteDataStore.cpp at WebKit::WebPageProxy::loadRequest(...) No app-level exception is thrown, and the extension terminates with: Thread 10: EXC_BREAKPOINT (code=1, subcode=0x1a31dbe00) It appears that WKWebView initialization or WebsiteDataStore creation is now restricted in extension contexts on iOS 26, but this change is not documented in the SDK release notes. Could you please confirm if this is an intentional sandbox restriction in iOS 26 or a regression in WebKit? Steps to reproduce: Implement an App Extension using ASAuthorizationProviderExtensionAuthorizationRequest. Create a WKWebView instance in the extension. Attempt to load a SAML login request (POST request with headers). Observe immediate crash on iOS 26 (works fine on earlier versions). Expected behavior: WKWebView should load the request or fail gracefully as in prior releases, without crashing the extension process. Request: Please clarify if WKWebView usage inside extensions is officially unsupported as of iOS 26, and if so, recommend an alternative approach for handling SSO flows.

PDF links in WKWebView not clickable on iOS 26 (working on pre-iOS 26)
Hello Apple Developer Community, I'm experiencing an issue with PDF link interaction in WKWebView that appears to be specific to iOS 26. Problem Description: I'm loading a PDF in WKWebView.The links may vary widely and are not necessarily DPF, so I need to load them using WKWebView. On iOS versions prior to 26, links within the PDF are clickable and work correctly. On iOS 26, the same links are not clickable (no response when tapped). Expected Behavior: PDF links should remain clickable and functional across all iOS versions. What I've Tried: Tested opening the PDF directly in Safari on iOS 26 - links still not clickable This suggests the issue might be related to changes in the system's PDF rendering engine Reproduction Steps: Load the PDF URL in WKWebView Navigate to page 12 Attempt to tap the link Environment: Test Devices: iPhone 15(26.0 ) / iPhone 16 Pro Max(18.0.1 ) Xcode: 16.2 Questions: Is this an intentional change in iOS 26's PDF handling or WKWebView? If so, is there a new API or configuration to restore link interactivity? Any guidance or suggestions would be greatly appreciated!

iOS 26 WKWebView PDF Background Color Changed to Gray
Hello We've encountered an issue with WKWebView in the latest iOS 26 beta. When loading a PDF URL, the background of the PDF viewer now displays as a dark gray instead of the expected white. Device: iOS 26 Simulator/Device Component: WKWebView Issue: The background color of the loaded PDF is gray. Expected Behavior: The background should be white, as it has been in all previous iOS versions. Link for Testing: https://help.apple.com/pdf/security/en_US/apple-platform-security-guide.pdf We confirmed that the same PDF and code render with a white background on iOS 26 and earlier. Questions: Is this an intentional change in iOS 26's WKWebView? If so, is there a new property or configuration setting available to control the background color of the PDF viewer within WKWebView? We would like to have the ability to set it back to white. Any insights, workarounds, or information on this matter would be greatly appreciated. Thank you.

the passkey suggestion does not appear; instead, the password suggestion appears on iPhone.
Create shortcut to open chrome with url and put it on the desktop. Tap the shortcut. Tap the username text field. When launching Safari from an iOS shortcut on an iOS device with a valid passkey registered, the passkey suggestion does not appear; instead, the password suggestion appears sometimes.

Tracking Campaigns (Downloads) with Smart App Banners
Hello, I've got Smart App Banner set up on my website. However, I want to be able to measure the traffic coming from this banner to the app store / app (i.e. measure impressions/downloads). Apple documentation (https://developer.apple.com/help/app-store-connect/view-app-analytics/manage-campaigns/) says you can set up a campaign link and use it in the Smart Banner to track those who download / open the app store page using your smart banner (so that we can get attribution). However, there is no documentation at all in terms of how this should be added to the tag when implementing a Smart App Banner. I've tried so many different variations and none have tracked downloads. This includes a structure based on an example taken from WWDC from a few years back which also did not work. I would appreciate any help!

DOMContentLoaded not working in Safari App Extension
I am trying to run JavaScript only after the page has loaded, and according to here - https://developer.apple.com/documentation/safariservices/safari_app_extensions/injecting_a_script_into_a_webpage, I should use DOMContentLoaded. However, it does not seem to work. This is my content.js file: function runOnStart() {     document.addEventListener('DOMContentLoaded', function(e) {         document.body.style.background = "rgb(20, 20, 20)";         document.html.style.background = "rgb(20, 20, 20)";                var divElements = document.body.getElementsByTagName('div');         for(var i = 0; i < divElements.length; i++) {             let elem = divElements[i];             elem.style.background = "rgba(255, 255, 255, 0.05)";         }     }); } runOnStart(); If I take the code outside of the event listener, it runs fine, but a lot of the elements haven't loaded in yet so it doesn't work as it should. The function is definitely running, but the event listener simply doesn't work. I appreciate any help you can give!

Detecting Navigation Redirect Chains
I'm building a macOS extension that needs to track multi-step navigation chains (A → B → C) to adjust behavior based on where users came from. Current approach: Using webNavigation.onBeforeNavigate to detect intermediate steps, but experiencing issues in Safari that don't occur on Chrome/Firefox/Edge. Questions: Is webNavigation the right API for tracking redirect chains in Safari? Does ITP/Private Browsing affect event delivery? Any alternative approaches recommended? (Safari version 26.0.1) Any guidance appreciated!

I have a question about Safari running in the background on iOS and iPadOS.
I coded two demo websites as follows (both written in NextJS): Website 1: I coded an interval counter that increments every 1 second. Website 2: I used the MediaRecorder API (described in the WebKit documentation: https://webkit.org/blog/11353/mediarecorder-api/). In the ondataavailable function, I periodically send a blob (once every 1 second) to my server. In the backend, I coded a POST API to upload this blob. I noticed that with website 1, the interval doesn't work when I run Safari in the background, even on iOS and iPadOS. However, website 2 works, meaning it still calls my API normally (I tried running Safari in the background for about 1-2 hours and it worked). So, does this mean Apple allows native APIs like MediaRecorder and its callbacks to run in the background?

WKWebView crashes in SSO App Extension on iOS 26 during loadRequest
We have a SAML-based SSO App Extension that uses WKWebView to load the SAML login request. This implementation has been working correctly on iOS versions prior to 26. However, starting with iOS 26, the extension consistently crashes when calling WKWebView.load(_:). The crash occurs inside WebKit, specifically in: /Library/Caches/com.apple.xbs/Sources/WebKit/Source/WebKit/UIProcess/WebsiteData/WebsiteDataStore.cpp at WebKit::WebPageProxy::loadRequest(...) No app-level exception is thrown, and the extension terminates with: Thread 10: EXC_BREAKPOINT (code=1, subcode=0x1a31dbe00) It appears that WKWebView initialization or WebsiteDataStore creation is now restricted in extension contexts on iOS 26, but this change is not documented in the SDK release notes. Could you please confirm if this is an intentional sandbox restriction in iOS 26 or a regression in WebKit? Steps to reproduce: Implement an App Extension using ASAuthorizationProviderExtensionAuthorizationRequest. Create a WKWebView instance in the extension. Attempt to load a SAML login request (POST request with headers). Observe immediate crash on iOS 26 (works fine on earlier versions). Expected behavior: WKWebView should load the request or fail gracefully as in prior releases, without crashing the extension process. Request: Please clarify if WKWebView usage inside extensions is officially unsupported as of iOS 26, and if so, recommend an alternative approach for handling SSO flows.

PDF links in WKWebView not clickable on iOS 26 (working on pre-iOS 26)
Hello Apple Developer Community, I'm experiencing an issue with PDF link interaction in WKWebView that appears to be specific to iOS 26. Problem Description: I'm loading a PDF in WKWebView.The links may vary widely and are not necessarily DPF, so I need to load them using WKWebView. On iOS versions prior to 26, links within the PDF are clickable and work correctly. On iOS 26, the same links are not clickable (no response when tapped). Expected Behavior: PDF links should remain clickable and functional across all iOS versions. What I've Tried: Tested opening the PDF directly in Safari on iOS 26 - links still not clickable This suggests the issue might be related to changes in the system's PDF rendering engine Reproduction Steps: Load the PDF URL in WKWebView Navigate to page 12 Attempt to tap the link Environment: Test Devices: iPhone 15(26.0 ) / iPhone 16 Pro Max(18.0.1 ) Xcode: 16.2 Questions: Is this an intentional change in iOS 26's PDF handling or WKWebView? If so, is there a new API or configuration to restore link interactivity? Any guidance or suggestions would be greatly appreciated!

iOS 26 WKWebView PDF Background Color Changed to Gray
Hello We've encountered an issue with WKWebView in the latest iOS 26 beta. When loading a PDF URL, the background of the PDF viewer now displays as a dark gray instead of the expected white. Device: iOS 26 Simulator/Device Component: WKWebView Issue: The background color of the loaded PDF is gray. Expected Behavior: The background should be white, as it has been in all previous iOS versions. Link for Testing: https://help.apple.com/pdf/security/en_US/apple-platform-security-guide.pdf We confirmed that the same PDF and code render with a white background on iOS 26 and earlier. Questions: Is this an intentional change in iOS 26's WKWebView? If so, is there a new property or configuration setting available to control the background color of the PDF viewer within WKWebView? We would like to have the ability to set it back to white. Any insights, workarounds, or information on this matter would be greatly appreciated. Thank you.

the passkey suggestion does not appear; instead, the password suggestion appears on iPhone.
Create shortcut to open chrome with url and put it on the desktop. Tap the shortcut. Tap the username text field. When launching Safari from an iOS shortcut on an iOS device with a valid passkey registered, the passkey suggestion does not appear; instead, the password suggestion appears sometimes.

Tracking Campaigns (Downloads) with Smart App Banners
Hello, I've got Smart App Banner set up on my website. However, I want to be able to measure the traffic coming from this banner to the app store / app (i.e. measure impressions/downloads). Apple documentation (https://developer.apple.com/help/app-store-connect/view-app-analytics/manage-campaigns/) says you can set up a campaign link and use it in the Smart Banner to track those who download / open the app store page using your smart banner (so that we can get attribution). However, there is no documentation at all in terms of how this should be added to the tag when implementing a Smart App Banner. I've tried so many different variations and none have tracked downloads. This includes a structure based on an example taken from WWDC from a few years back which also did not work. I would appreciate any help!

DOMContentLoaded not working in Safari App Extension
I am trying to run JavaScript only after the page has loaded, and according to here - https://developer.apple.com/documentation/safariservices/safari_app_extensions/injecting_a_script_into_a_webpage, I should use DOMContentLoaded. However, it does not seem to work. This is my content.js file: function runOnStart() {     document.addEventListener('DOMContentLoaded', function(e) {         document.body.style.background = "rgb(20, 20, 20)";         document.html.style.background = "rgb(20, 20, 20)";                var divElements = document.body.getElementsByTagName('div');         for(var i = 0; i < divElements.length; i++) {             let elem = divElements[i];             elem.style.background = "rgba(255, 255, 255, 0.05)";         }     }); } runOnStart(); If I take the code outside of the event listener, it runs fine, but a lot of the elements haven't loaded in yet so it doesn't work as it should. The function is definitely running, but the event listener simply doesn't work. I appreciate any help you can give!

Detecting Navigation Redirect Chains
I'm building a macOS extension that needs to track multi-step navigation chains (A → B → C) to adjust behavior based on where users came from. Current approach: Using webNavigation.onBeforeNavigate to detect intermediate steps, but experiencing issues in Safari that don't occur on Chrome/Firefox/Edge. Questions: Is webNavigation the right API for tracking redirect chains in Safari? Does ITP/Private Browsing affect event delivery? Any alternative approaches recommended? (Safari version 26.0.1) Any guidance appreciated!

I have a question about Safari running in the background on iOS and iPadOS.
I coded two demo websites as follows (both written in NextJS): Website 1: I coded an interval counter that increments every 1 second. Website 2: I used the MediaRecorder API (described in the WebKit documentation: https://webkit.org/blog/11353/mediarecorder-api/). In the ondataavailable function, I periodically send a blob (once every 1 second) to my server. In the backend, I coded a POST API to upload this blob. I noticed that with website 1, the interval doesn't work when I run Safari in the background, even on iOS and iPadOS. However, website 2 works, meaning it still calls my API normally (I tried running Safari in the background for about 1-2 hours and it worked). So, does this mean Apple allows native APIs like MediaRecorder and its callbacks to run in the background?
