From a mail app or similar, when opening a webpage in Safari as an external browser, JavaScript on the webpage stops running if Safari goes into the background. Is there a way to prevent this from happening?
Sample code for the counter:
Behavior: Upon returning from the background, the counter continues for about 7-8 seconds but does not progress further.
For example, if Safari is kept in the background for about 20 seconds and then brought back, the counter stops at around 7-8 seconds and only resumes counting after returning to the foreground.
Expectation: The counter should continue running even if Safari goes into the background.

I want to migrate from a Safari App Extension to a Safari Web Extension, but don't know how to get rid of the message, telling users that my extension can access their passwords. Here is a message which I see:
I was thinking that this might be because all Safari Web Extension get this type of access, but I have a Safari Web Extension which does not require such level of access:
Here is the manifest:
{
"manifest_version": 2,
"default_locale": "en",
"name": "__MSG_extension_name__",
"description": "__MSG_extension_description__",
"version": "1.1",
"icons": {
"48": "images/icon-48.png"
},
"background": {
"scripts": [
"background.js"
],
"persistent": true
},
"browser_action": {
"default_popup": "popup.html",
"default_icon": {
"16": "images/toolbar-icon-16.png"
}
},
"permissions": [
"nativeMessaging", "tabs"
]
}
and here is the Info.plist file:
Here is the entire code of the extension:

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.
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).

I have a Safari App Extension which allows users to switch between last open tabs with a shortcut option+tab in the same way it's possible to switch between last open apps with command+tab.
Here is how i do it:
I inject a content script on all websites which has the only thing – key listener for option+tab presses.
When a user presses option+tab, that keyboard listener detects it and sends a message to the Safari Handler.
Then Safari Handler sends a message to the containing app and it shows a panel with last open tabs.
This approach has a problem: it shows a message to a user in settings: "Can read sensitive info from web pages, including passwords..."
Which is bad, because in reality i don't read passwords.
If i remove SFSafariContentScript key in the Safari App Extension target's Info.plist, then this message about reading sensitive data disappears, but then i loose the ability to open the tabs panel.
How can I open my app window with a shortcut without frightening a user?
It's possible to listen to global key presses, but that would require a user to grant the app permissions of Accessibility (Privacy & Security) in macOS system settings, which also sounds shady.
I know an app which does not require an Accessibility permission: https://apps.apple.com/ua/app/tabback-lite/id6469582909 and at the same time it does not tell a user about reading sensitive data in the extension settings.
Here is my app: https://apps.apple.com/ua/app/tab-finder/id6741719894 It's open-source: https://github.com/kopyl/safari-tab-switcher
There are two issues about SFSafariViewController.
After rotate from landscape to portrait,
The topAnchor is destroyed.
The specified bar tint color and control tint color are invalidated.(Returns to system color)
Regarding the second issue, I’ve found a temporary workaround.
Override the viewWillTransition(to:with:) and keep it empty. Don't call super.viewWillTransition(to:with:).
Since UIKit is not open source, I don’t know the exact cause, but I found something that could be the key to the issue. So, I reported it to Apple Feedback Assistant. You can check the details and the sample project in the GitHub repository below.
https://github.com/ueunli/SafariViewer
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.
Hello,
I am developing Safari Content Blocker extension and discovered that it frequently fails to load with large amount of rules. Currently I have over 45k and most of the time when I reload the extension on iOS 18 (iPhone 12) it ends with error:
Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.SafariServices.ContentBlockerLoader" UserInfo={NSDebugDescription=connection to service named com.apple.SafariServices.ContentBlockerLoader} #0
And the simpler message is just:
Couldn’t communicate with a helper application.
From what I managed to find (for example here - https://developer.apple.com/forums/thread/756931) the limit for blocking rules should be 150k items.
It was previously 50k but got increased years ago.
Is there anything special I need to do to get the extension to work reliably with say 100k items?
I am usng the JSON format from the docs:
{
"trigger": {
...
},
"action": {
...
}
},
{
"trigger": {
...
},
"action": {
...
}
}
]
My trigger is url-filter and the action is type: block
I was thinking about providing multiple JSON files in attachments property of NSExtensionItem but apparently that is not supported.
Thanks for help!
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.

I’m currently porting a Chrome Extension to Safari and integrating it with native messaging in a Safari Web Extension. As part of this, I’m building a proxy to forward messages between the web extension and a socket in another application, both ways. Additionally, the socket occasionally broadcasts messages that also need to be sent to the web extension.
The issue I’m facing is that the app extension terminates whenever I call context.completeRequest(returningItems: nil), which prevents me from listening for incoming messages from the socket (I'm using the Network Framework). To work around this, I’ve tried not calling context.completeRequest(returningItems: nil), which keeps the app extension running. However, I’m unsure if this is the right approach—currently, I’m simply ignoring the response and relying entirely on SFSafariApplication.dispatchMessage.
According to the documentation, the app extension lifecycle ends when the system terminates it, but I need to keep the socket listener active.
Has anyone encountered a similar issue, or does anyone have suggestions for maintaining the socket connection while adhering to the app extension lifecycle?
Any insights would be greatly appreciated!

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. (115740959) (FB13188943)
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.

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:

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!

Since recently (maybe after updating to Sonoma 14.7.1 - 23H222, but not sure, I get a crash report stating that SafariBookmarksSyncAgent quitted unexpectedly Once acquitted the report, it will reappear 2 minutes later as long as Xcode is open.
Configuration:
Sonoma 14.7.1
Safari Technology Preview Release 208 (Safari 18.2, WebKit 19621.1.5.1)
Xcode 15.3 (15E204a)
That seems to be a known problem.
Question: Is it due to MacOS version ? To Xcode version ? To Safari version ? To webKit version ? Or to simulator, as I gat an AegirPoster crash (as described here: https://stackoverflow.com/questions/77083912/macbook-pro-crashes-when-using-simulator-aegirposter-process)
I read that I would need to restart some devices (eg, iPhone). That seems to temporarily solve the problem

I filed a bug report: Nov 27, 2024 at 3:41 PM – FB15976427
I noticed that when logging in to idmsa.apple.com, my old email address still appears as an option, even though I’ve updated my Apple ID to a new email. I understand that passkeys rely on a public-private key pair, with the public key stored on the server (e.g., idmsa.apple.com) and the private key saved locally in iCloud Keychain.
Could you please clarify:
1. How can I request Apple to delete the public key associated with my old email address from their servers?
2. Is there a way for users to manage or update server-side passkeys without contacting Apple support?
3. Does this behavior affect my account security in any way?
Any advice or insights would be greatly appreciated!
Hello there
my iPhone 16 pro max has an issue with safari and apple support couldn’t help me there and said I should get help here
Safari completely doesnt work
it doesn’t start and if it starts it crashes
can anyone help me to get safari useable
In Safari Web Extensions on iOS 18, declarativeNetRequest Rulesets and Dynamic Rules take over twice as long to apply -- which causes rulesets to often fail to apply before sites load. In a boilerplate Xcode project you can note the time difference toggling the OISD (https://oisd.nl) ruleset on iOS 17 and iOS 18 simulators. Additionally, if you force quit Safari and reopen to a site with ads blocked by OISD list (e.g. espn.com) the content will be blocked in that initial state on iOS 17, but not in iOS 18 due to the latency.
Based on the boilerplate extension, this bug is impacting all Mobile Safari Extensions using declarativeNetRequest Rulesets and Dynamic Rules. We know several other extension developers dealing with this issue.
Our team wrote detailed reproduction steps in our Feedback Assistant ticket: https://feedbackassistant.apple.com/feedback/15196130 but have received no responses. I would attach a screen recording here but it won't allow me.

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!
