Hi! I'm working on an iOS Safari extension that has a ServiceWorker. Lately we've noticed that this ServiceWorker seems to get killed seemingly at random, and there are no logs or crash reports to tell us what happened. I'm hypothesizing that iOS might be shutting down Safari ServiceWorkers when the ProcessInfo.thermalState approaches .serious. I have circumstantial evidence that our ServiceWorker tends to get killed more often at higher levels of thermalState but can't yet say conclusively that this is the case. I can't find any direct evidence of this on internet searches either. Is anyone able to shed light onto this topic? The specific symptoms are: ServiceWorker stops, and the menu entry for its console window no longer appears on macOS Safari. No crash logs via Xcode or Sentry, and no Console messages as far as we could tell (caveat: MobileSafari generates a LOT of messages! We might have missed it.) If attached via debugger, the native part of our extension just disappears and the debugger loses connection with no error message. ServiceWorker no longer works for the lifetime of the Safari process. Sometimes, when we kill Safari and restart, we can get the ServiceWorker back. This usually requires toggling our extension's "enabled" state in system settings. In some cases, even killing/relaunching Safari and toggling the system setting doesn't bring our ServiceWorker back. I'm hypothesizing right now that this happens when the thermal state is high. I've tried simulating a serious/critical thermal state in the Xcode Devices window, but couldn't repro the ServiceWorker problem. I don't know if that setting affects the whole system, though, or just our own apps. Help appreciated! Yuna

The SFSafariViewController documentation mentions not to display content from websites when using the pageSheet and formSheet presentation styles for the In-App browser. Is this a hard restriction that is enforced or more of a loose guideline? And if possible, providing the reasoning behind it would be great. Thanks in advance.

Scenario: Apple decided to not support PWAs in Europe in IOS 17.4. My company has multiple Angular PWAs, all using IndexedDB and providing full offline-usage as main feature, that apparently won't work anymore. The apps communicate with a server. We maintain two versions of that server, e.g. v1.1 and v1.2 - some customers don't want or can't upgrade to v1.2 just yet. Not all new features of an app will get implemented in v1.1, and eventually we won't push updates for it anymore. At some point, we'll have the same situation with e.g. v1.2 and v1.3. My questions: Do I understand correctly that offline-usage and IndexedDB features won't work anymore? If I wrap the PWAs via Capacitor and upload them as Custom App via App Store Connect, in IOS 17.4... Will the app, including routing, work offline? Will the IndexedDb still be usable as permanent data storage? Can I upload v1.1 and v1.2 as separate apps or will I have to create on app with in-app purchase options? If it's the latter, how do I push updates? Apparently, Apple Review can cause problems with separate apps that have similar functions... Thank you for your time!

Hello, since the last iOS 17.4 Europe update, and since the implementation of new rules for default browsers, PWAs no longer work. In fact, they are nothing more than shortcuts for internet pages, so this makes the application unusable, which could not necessarily be launched in install mode with notifications. I tried looking for changes but couldn't find them. I think it's linked to the fact that you can install applications from the web from a marketplace. If anyone has a solution or the same problem. Thank you

I recently noticed that using Google Docs, Google Sheets, and any other Google-related sites on a Safari browser uses tons of RAM. It usually consumes around 4-5 GB of RAM. Compare it to when I use Google Docs on Chrome; it only uses around 1-2 GB. Why is this so? I want to use Safari alone for work, but it's so slow. Do you have any tips on this?

Problem : Deep links are not directing users to the intended apps, instead, they are redirecting to the respective apps on app store. When clicking on a deep link in private mode, it consistently displays a prompt to open the application or cancel. If the "Cancel" button is selected on the prompt, it redirects to the app store via a deep link to open the specific application, on next time onwards we are not receiving the prompt to open application, every time it get redirects to the appstore via merchant link automatically. In other case if we click open button on the prompt , it redirects to the application, Subsequently, each time we click the deep link, it repeatedly prompts us to open the app. Why do the "Open" and "Cancel" buttons lead to different outcomes in these scenarios? How can we ensure that the application always opens when clicking on the deep link, if it is in private mode as well?

Hello, I am in the process of converting a Web Extension to a Safari Extension. I need to use browser.downloads.onCreated.addListener in my extension but the browser.downloads API is not supported yet. Do I have another way to do that?

I'm experiencing an issue with the Smart App Banner on my website, and I'm seeking assistance in resolving it. I have followed Apple's guidelines for implementing the Smart App Banner on my website, but it doesn't seem to work as expected when the app is not installed on the user's device. Here are the details of my setup: I have added the following meta tag to the root index file of my website: html <meta name="apple-itunes-app" content="app-id=, app-argument=myapp.com"> In the .well-known folder, I have created an apple-app-site-association file with content like this: { "applinks": { "apps": [], "details": [ { "appID": "HGU83XXXXX.com.myapp.app", "paths": ["*"] } ] } } The issue I'm encountering is that the Smart App Banner only displays with the "Open" button when the app is already installed on the user's device. However, when the app is not installed, the Smart App Banner doesn't appear to prompt users to download the app from the App Store. I would appreciate any insights or guidance on how to make the Smart App Banner work correctly, especially when the app is not installed on the user's device. Are there any specific steps or configurations I might be missing in this implementation? Thank you for your assistance!

Hello, I try to develop extension for safari. I edited info.plist but I can't see my menu items. My Info.plist page <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>NSExtension</key> <dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.Safari.web-extension</string> <key>NSExtensionPrincipalClass</key> <string>$(PRODUCT_MODULE_NAME).SafariWebExtensionHandler</string> </dict> <key>SFSafariContextMenu</key> <array> <dict> <key>Text</key> <string>Search for selected text in MyApplication.</string> <key>Command</key> <string>Search</string> </dict> <dict> <key>Text</key> <string>Add an entry for selected text in MyApplication.</string> <key>Command</key> <string>Add</string> </dict> </array> <key>SFSafariWebsiteAccess</key> <dict> <key>Level</key> <string>All</string> </dict> </dict> </plist>

Hello, safari consumes less CPU than Chrome, but it does not consume less RAM. When you access YouTube in Safari, especially when you skip 5 seconds while watching a video, the buttons are very inadequate compared to Chrome. The video and audio lag, the loading sign appears and the audio lag is very annoying. At the same time, when I log into Twitter, some videos do not play but remain loading. While browsing the web in Safari, the mouse sometimes remains stuck. While typing, the mouse becomes a line, but when I hover over something to click, it still remains as a line. There are such bugs. I like to use Safari, it is very useful, but I always prefer to stay in Chrome because of such errors. I try it every time Apple updates Safari, most bugs go away, but new ones come and unfortunately the Youtube problem is very bad. This problem only occurs on YouTube, not on Netflix and similar platforms. Browsing YouTube with Safari is very annoying. I hope you find a solution to these problems soon. Since I deal with CDN and Linux servers, the web is very important to me and I like the safari web tool part, but it is not an immersive view. It gives the impression that I shouldn't have opened it. I hope a new design language will be added to this design. Other than that, using safari is nice and I love how minimalist it is. Thank you, I wish you good work.

Hi, this is my first time to write in Forum. My Problem is that, when I have a video in Safari for Mac recorded, Safari is splitting my record into three blobs. For Example Chrome doesn't. There is one record, one blob. Safari Version: 16.6 (18615.3.12.11.2) Does anyone know why Safari splits one Record/blob into three blobs? Thank you and have a great day.

Hello, i try to send a Web Push Notification to my Safari Webbrowser and use the "http2" Module from Node.js Every other Browser is able to receive my messages. I got the message "BadJwtToken" but when i use the same Authorization Key with a HTTP/1.1 Request, i got a Message on Safari. Is there a Problem with the API when i use the HTTP/2 Protocol? Has anybody the same Problem? I send exactly the same Headers and as i said other Push APIs from Mozilla,Chrome and Microsoft e.t.c. are working with my HTTP2 Client.

I'm curious if there is a limit to number of PWA push notifications that can be sent. We estimate roughly 10,000 pushes a day. If anyone has any insight it would be greatly appreciated.

You used to be able to create custom Widgets using Safari to view a section of a website. The "open in dashboard" option is no longer there. what is the process to do this now?
