I am currently developing an iOS app that needs to embed a third-party website. On this website, the best view is achieved in the standard Safari app by pressing the 'Aa' button on the left side of the address bar and setting the zoom to 50%. I want to replicate this 50% scaling in WKWebView, but I'm not sure how to accomplish it. I've tried using webView.pageZoom = 0.5 and setting webView.scrollView.minimumZoomScale = 0.5 webView.scrollView.maximumZoomScale = 0.5 but it doesn't display the same way as it does in Safari. How can I achieve the same scaling effect in WKWebView?

In iOS version 17.4 and above, we have observed that the following code works fine upon the initial opening. However, after minimizing the page and reopening it, there is a chance of encountering issues with abnormal lines. Please note the reproduction conditions: try minimizing the page, opening other apps, and then reopening it multiple times. The code is in the comments section. first time： After minimizing and reopening...

I am trying to sync up the selected tab bar item once a user presses back and navigates back in the web wrapper iOS app. Here is how the app works: When a user logs in, they are presented with the Home Screen. To navigate, the select a tab item on the tab bar. This tells webkit to redirect to that URL and then that webpage is shown in the app (wrapped). A back button also appears. When a user presses the back button, the webView.goBack() method sends the user back on in the webView.backForwardList. What happens then is that the user is now on the previous page, however the tab bar has not updated. In other words, the user is back on the first tab but the second tab is highlighted. I tried fixing this by telling the tab bar controller what item to select, however this creates a state malfunction because it also tells the webView to navigate to that url again, so in fact this means that the user isn't going back through web history, but actually is going forward while simulating going back. I need to be able to highlight the tab bar items that sync up with the page that we have gone back to without selecting it. Does anyone have an idea for how to manually highlight or select a tab bar item without actually navigating to that tab bar item? Thank you!

Hi Everyone, I scanned my iPhone SE 3d generation with the iMazing app developed by Amnesty International, and after the scan it detected 3 Warnings on my iphone.

I modified an InputMethodKit example (fairly recent one from github, compiled fine and worked as expected on my machine as it was) to create a window with a WKWebView and the window doesn't load. I know that loadView is getting called, but the window never appears after calling showWindow on the window controller and there is a mysterious error in the console: bootstrap_check_in(): (os/kern) unknown error code (44c) From googling this it seems App Sandbox related, but I think I have everything set up correctly (App Sandbox on with outgoing connections allowed) Totally stumped, any help or ideas would be appreciated Here's the relevant code: View controller import Foundation import WebKit import AppKit class InputWindowViewController: NSViewController, WKUIDelegate { var webView: WKWebView! override func loadView() { NSLog("LoadView") webView = WKWebView() self.view = webView webView.uiDelegate = self webView.needsDisplay = true } override func viewDidLoad() { super.viewDidLoad() webView.load(URLRequest(url: URL(string:"https://www.apple.com")!)) } } Window controller import AppKit import Foundation import WebKit class InputWindowController: NSWindowController { var controller: InputWindowViewController? override init(window: NSWindow?) { controller = nil super.init(window: window) } override func loadWindow() { self.window = NSWindow(contentViewController: controller!) } required init?(coder: NSCoder) { controller = nil super.init(coder: coder) } } AppDelegate import Cocoa import InputMethodKit import WebKit // Necessary to launch this app class NSManualApplication: NSApplication { private let appDelegate = AppDelegate() override init() { super.init() self.delegate = appDelegate } required init?(coder: NSCoder) { // No need for implementation fatalError("init(coder:) has not been implemented") } } @main class AppDelegate: NSResponder, NSApplicationDelegate { var server = IMKServer() var candidates = IMKCandidates() var inputWindowController = InputWindowController() func applicationDidFinishLaunching(_ notification: Notification) { // Insert code here to initialize your application server = IMKServer(name: Bundle.main.infoDictionary?["InputMethodConnectionName"] as? String, bundleIdentifier: Bundle.main.bundleIdentifier) inputWindowController = InputWindowController() inputWindowController.controller = InputWindowViewController() inputWindowController.loadWindow() inputWindowController.showWindow(self) candidates = IMKCandidates(server: server, panelType: kIMKSingleRowSteppingCandidatePanel, styleType: kIMKMain) NSLog("tried connection") } func applicationWillTerminate(_ notification: Notification) { // Insert code here to tear down your application } } This code is probably awful in a lot of other ways I don't realize, but I wanted to get a webview window up before I put a bunch of time into this thing XCode 13.4 MacoOS 12.7.4

I am currently working on an iOS application where I want to implement the safari tabs and when I have to minimize that one to check how many numbers of tabs are opened. How can I do this?

Hi all, An app that until yesterday would take 1 second to render a list in the WKWebView is now taking over 3 minutes to load. No changes have been made to the app or the content that it is showing. I have tested on a device running 17.3, and performance has been acceptable, and then updated to the latest security fix (17.4.1) and now 3 minutes. Having read the release notes https://support.apple.com/en-us/HT214097 I cant see what would have affected either the processing of javascript or the rendering of content within the web view. My team is currently running all our apps that use a hosted WKWebView within it to ensure that they aren't affected, but this one app is now unusable and safety concern for the users (Airline Safety). Has anyone else experienced this or has a workaround - Sorry there are no logs (I have been scanning the device logs and nothing new is appearing - almost as if the operation is just dead locked).

Hello, Currently, my app only uses web view to load HTML data and external safari web view by link click. I have seen the following developer's details. So if HTML data load on web view needs data collection enabled, then which Types of data need to be added to data collection? Also. if we disable all types of Data collection from privacy. Is apple will allow you to submit the app? or Reject it? Any help will be appreciated. Thanks

Hello Apple We have read your guide on https://developer.apple.com/documentation/bundleresources/privacy_manifest_files#4284009 and it is unclear how the NSPrivacyTrackingDomains affects WebView functionality of the app. We have WebView based functionality we use for signup/ login of customers in the app and that can potentially track users. It is stated that If the user has not granted tracking permission through the App Tracking Transparency framework, network requests to these domains fail and your app receives an error. However based on our testing the domains listed in NSPrivacyTrackingDomains have no effect on network requests happening in the WebView if the user declines tracking via the App Tracking Transparency prompt. (e.g pages are loaded, network requests to listed tracking domains are happening) Can you confirm it is the case on what should de done about it? Right now we have a custom implementation on our side that passes the result of the App Tracking Transparency prompt to the WebView instructing it weather it can send requests to tracking domains or not.

Is there any reference/documentation/discussion about the motivation for including the WKWebView loadSimulatedRequest() method? Is it intended to be used for testing? Page load performance enhancement? I'm wondering if there is a way to leverage its usage in our webview dependent app.

Is it possible to generate pdf data from a html content, including the background graphics (background color, box shadow, etc..) ? Right now, I can only make a pdf view from the apple website like this: It can be seen that the background images and colors are missing.

Our app uses Azure B2C for SSO login, and we are noticing a bug on Safari 17.x (any browser on iOS 17.x, and Safari 17 on Mac OS) where the Azure B2C cookies go missing during the registration process, which leads to a broken user experience. The following cookies are the ones that go missing The only forum posts related to this issue I have come across are these: https://techcommunity.microsoft.com/t5/azure/azure-app-on-ios-17-not-working/m-p/3958809 Which links to this https://techcommunity.microsoft.com/t5/intune-customer-success/day-zero-support-for-ios-ipados-17-and-macos-14/ba-p/3930010 Is this in bug that will be fixed in an upcoming release on Safari 17.x?

How exactly am I supposed to implement the following delegate method of WKWebView? func webView(_ webView: WKWebView, showLockdownModeFirstUseMessage message: String, completionHandler: @escaping (WKDialogResult) -> Void) The problem: the delegate method is defined to be available since iOS 13. But "WKDialogResult" in the completion handler is declared to be available since iOS 16. So this is already very odd and probably a bug in the API declaration. When I make the delegate method available since iOS 16 (via @available (iOS 16.0,*)) then Xcode gives me an error stating that this method must be provides for iOS 14 and later. But when it is made available since iOS 14 (or 13), then I get the error that WKDialogResult is only available since iOS 16. So this looks like a big messy bug in the API declaration, or did I miss something here? It would not the first bug in the API declaration of the WKWebView where the availability is wrong (for example the property "upgradeKnownHostsToHTTPS" is declared to available since iOS 14.5, but in reality it is only available since iOS 16 and would crash when used under iOS 14.5)

My videos have stopped loading on canvas after the iOS 17.4 update. I tried partially loading the videos instead of loading them entirely and it works on safari but not on chrome. Any ideas on how I can fix this issue? What is the recommended way of loading videos on canvas for browsers on iOS?
