My understanding is that the iOS service worker does not support background sync or a periodic sync. ( if this is not true please point me to the documentation that describes the support of these features... ) High level use case. My users of my app will be filling out forms during the day while off line ( out of cell phone coverage )... then at the end of the day they will travel back into coverage at which point the WEB app would automatically send those POSTS without User interaction. How would you accomplish this on an iOS device... ( key is without having to relaunch the app ) thank you

Is it possible to get 240Hz Apple Pencil events in Javascript? I know that with UIKit you have to poke at coalesced events to get this sort of sampling frequency, but it appears that Safari (and Mobile Safari) do not support the new PointerEvents.getCoalescedEvents() API (https://developer.mozilla.org/en-US/docs/Web/API/PointerEvent/getCoalescedEvents). Anyone know of another way to get high-frequency 240Hz Apple Pencil events (e.g. as touchmove or pointermove events)?

I am trying to implement Quick Notes through SwiftUI, rather than UIKit or AppKit. I am unsure if the behaviour below is expected, or due to a bug. I have already successfully implemented NSUserActivity for Handoff, Spotlight and Siri Reminders, using the .userActivity() view modifier. These NSUserActivity instances use the NSUserActivity.userInfo dictionary to store and correctly restore the content through the .onContinueUserActivity(perform: ) methods. Quick Notes requires using the .persistentIdentifier or .targetContentIdentifier properties, rather than the .userInfo dictionary alone. However, when I set these either of these to unique identifiers using the code below, they are not correctly stored within the useractivity. MyView() .userActivity(ActivityString, updateUserActivity) private func updateUserActivity(_ activity: NSUserActivity) {     activity.isEligibleForSearch = true     activity.isEligibleForHandoff = true     activity.title = "Title"     activity.targetContentIdentifier = myItemUniqueID     activity.persistentIdentifier = myItemUniqueID     activity.userInfo = ["id": myItemUniqueID]     print(activity.targetContentIdentifier) // Correctly prints     print(activity.persistentIdentifier) // Correctly prints     print(activity.userInfo) // Correctly prints     } The identifiers print correctly when setting the user activity above. However, when restoring the user activity (tested through Handoff and Spotlight Search), the targetContentIdentifier and persistentIdentifier strings are empty. MyView()     .onContinueUserActivity(ActivityString, perform: continueUserActivity) private func continueUserActivity(_ activity: NSUserActivity) {     print(activity.persistentIdentifier) // Nil     print(activity.targetContentIdentifier) // Nil     print(activity.userInfo) // Correctly prints     } Is there something else I must do, or is this unexpected behaviour?

I continually receive this error when using AdMob Banners (swift 5, on iOS simulator and devices using Xcode 13.5) it seems something related to Webkit, this continuous exception slows my app and continually produce network calls [ProcessSuspension] 0x10c240f60 - ProcessAssertion: Failed to acquire RBS assertion 'WebProcess Background Assertion' for process with PID=94309, error: Error Domain=RBSServiceErrorDomain Code=1 "target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit" UserInfo={NSLocalizedFailureReason=target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit}

Hello I have a webrtc-based web app that is loaded inside a WKWebView. The web app gets loaded just fine in our iOS App running WKWebView on an iPad with iOS 15.1. We are using the exact same app, built for Mac Catalyst. However, on the Mac version, the web app gets loaded but the RTCPeerConnection object is undefined.. Meaning that our web app assumes that WebRTC is not available in that browser. Isn't the native app supposed to work the exact same on iOS and MacOS? Is the Mac version of WKWebView more limited than its iOS counterpart ? Is there any resource that states exactly what is supported in WKWebview in each platform? Thanks

Hi there - I am trying to port over Chrome extension over to Safari Web extension. Looks like Safari has a very aggressive permissions flow which isn't a great user experience but I get the privacy benefits. I am trying to move some of my permissions like <all_urls> or tabs as optional permissions and build a flow where I can request the user for them in hopes that i can educate them as to why I need them similar to how Chrome/FF have it. However when i use browser.permissions.request - i always end up getting true without invoking the prompt. The prompt seems to come up regardless when i start visiting a website. Can someone help with this? Sounds more like a defect in Safari.

Hello, I would like to track the amount of downloads, on Apple Store, of users coming from the Safari Smart Banner. The smart banner is displayed but we don't have any data in Apple Store. How can I track these downloads? We have a campaign link and I've tried three different ways and it didn't work. Thanks. I've tried: <meta name="apple-itunes-app" content="app-id=605512447, affiliate-data=pt=2000418&ct=iOS%20Smart%20Banner&mt=8”/> <meta name="apple-itunes-app" content="app-id=605512447, affiliate-data=pt=2000418&ct=iOS%20Smart%20Banner”/> <meta name="apple-itunes-app" content="app-id=605512447, affiliate-data=ct=iOS%20Smart%20Banner”/>

I would like to create a web app where you can drag and drop emails from Apple Mail (on macOS). When you drag emails to the desktop an .eml file is created, but when you drag emails to the browser no file is being transferred, I can only get the mail’s subject. So is it possible to drag and drop emails from Apple Mail to browsers? And if yes, then how? So far I've tried chrome and safari, but neither got any files with the dragged element. On windows with outlook or thunderbird this wasn’t an issue, so I hope it can be done with apple mail as well. Thanks in advance

Hi, According to Blocking Content with Your Safari Web Extension, we can now use the Declarative Net Request API to block content in a Safari Web Extension. However, not everything in the API has been implemented just yet. The supported RuleCondition are domainType, excludedResourceTypes, isUrlFilterCaseSensitive, regexFilter, and resourceTypes. Does anyone know when the initiatorDomains rule condition will be supported? In the meantime, is there a way for an extension to block requests based on an originator domain? Thanks

Whenever I'm on this site on Safari and I log in, after a little while pages will load very very slow or not at all and reeplies to posts will fail over and over. In general this website becomes unusable under safari and upon restarting (i can't just log out because that won't work either) Safari, everything works again. This affects the documentation pages too, not just the forums. So I'll quit, log in, try to put in my post as fast as possible before I can't anymore. I usually copy and paste my post before hitting submit incase my time has ran out.

Seeing an issue where document.cookie is returning an expired cookie. This cookie is correctly not sent in requests and is not displayed in the web inspector (Storage -> Cookies). Problem persists until safari is restarted. Affects the following user agents...

According to the release notes of STP, OffscreenCanvas has been implemented for a while. However, when I run JavaScript code, it fails because OffscreenCanvas is not a recognized command. I feel I’m missing something obvious here. Any help?

I have updated my web extension to use Manifest v3. While trying to test, I get the error: _The service_worker script failed to load due to an error. _ I do not see details on the error, or a place where to find details. Any suggestions?

I'm not sure what is special about Gmail, but my declarativeNetRequest rules are totally ignored. I make an web extension that blocks email trackers (1x1 pixel images embedded in emails to track if and when you open email sent to you). All images in Gmail are loaded through Google's proxy: googleusercontent.com/proxy/#originalURL But no matter what I do, I can't block a single image that is loaded in an email. To try and prove it is a bug in Safari, I created a new template web extension in Xcode. I block all resourceTypes (images and other should be all that is needed) and added two rules: Block all images loaded through Google's proxy server (this should block all embedded images in all emails) Block any image with copper in the URL (just in case the blocking doesn't apply to the proxy root url for some reason).  {   "id": 1,   "priority": 1,   "action": { "type": "block" },   "isUrlFilterCaseSensitive": false,   "condition": {    "regexFilter": "googleusercontent.com/proxy",    "resourceTypes": [     "image",     "media",     "main_frame",     "sub_frame",     "stylesheet",     "script",     "font",     "xmlhttprequest",     "ping",     "websocket",     "other"    ]   }  },  {   "id": 2,   "priority": 1,   "action": { "type": "block" },   "isUrlFilterCaseSensitive": false,   "condition": {    "regexFilter": "copper",    "resourceTypes": [     "image",     "media",     "main_frame",     "sub_frame",     "stylesheet",     "script",     "font",     "xmlhttprequest",     "ping",     "websocket",     "other"    ]   }  } ] Even though I know this isn't needed, I also added the requester domain (mail.google.com) and the proxy domain (googleusercontent.com) to the permissions list in the manifest file: ... "declarative_net_request": {    "rule_resources": [{      "id": "ruleset_1",      "enabled": true,      "path": "rules.json"     }]   },  "permissions": [    "declarativeNetRequest",    "*://mail.google.com/*",   "*://*.googleusercontent.com/proxy/*" ] If I open an email from copper, the image still loads in Gmail If I right click and select "Open Image in New Tab", the image will not load and I am told it was blocked If I open a test page that has two images in it, one the image from the email, the image is blocked and the other image is not (as expected, the second image is from wikipedia and should not be blocked) Running the same extension in Chrome DOES block the image in Gmail (and in all the other cases too)

My goal is to get the push notifications while I get the following error The following Swift pods cannot yet be integrated as static libraries when I run pod install .

Could some one say a solution to this issue?

I have an iOS native app. I have added WKWebView to view controller to show html content. class MyHTML1ViewController: UIViewController { private var webView: WKWebView! var htmlFile: String = "" // default value, can be changed override func viewDidLoad() { super.viewDidLoad() let url = Bundle.main.url( forResource: htmlFile, withExtension: "html") let request = URLRequest(url: url) webViewBase.load(request) } ... } I run the app on my iPhone through Xcode. It displays html content fine. However, on closing the view, I saw the following error messages in console: ProcessAssertion: Failed to acquire RBS assertion 'WebProcess Suspended Assertion' for process with PID=91330, error: Error Domain=RBSServiceErrorDomain Code=1 "target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit" UserInfo={NSLocalizedFailureReason=target is not running or doesn't have entitlement com.apple.runningboard.assertions.webkit}> Should I add webkit entitlement? how can I do it in Xcode? I prefer to get rid of this error message if they are just warning in console, does not causing app crash. My Xcode is Version 13.4.1.

When a WKWebView implements the WKNavigationDelegate protocol, clicking a link inside the webview gives back WKNavigationTypeLinkActivated as WKNavigationType in the decidePolicyForNavigationAction. But clicking on a link inside an iframe gives back WKNavigationTypeOther, which makes it impossible to know if the url is requested on load or on click. Context: When a webview loads html (and embedded css, js, iframes, or XHR calls from JS ...), decidePolicyForNavigationAction gives back WKNavigationTypeOther as actionType , so I know content is loading and should be rendered in the webview. When a link is clicked, it gives back WKNavigationTypeLinkActivated so I know I need to show an in-app browser to show the content. This isn't the case with links clicked within an iframe (an <a> tag with href attribute); they return WKNavigationTypeOther
