We're having problems in iOS 15.0+ with WKWebView and this assertion: [assertion] Error acquiring assertion: <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}>  [ProcessSuspension] 0x116004e40 - ProcessAssertion: Failed to acquire RBS assertion 'ConnectionTerminationWatchdog' for process with PID=11505, 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} No problems for iOS versions < 15, and disabling this feature fixed the issue for us. We are looking to understand if this feature is intended to be enabled as part of iOS 15's official release.

Hello Guys, Our application has default web browser entitlement: com.apple.developer.web-browser. However, I am not seeing it in Desktop Safari's Developer menu, I am using iPadOS 16 beta 2(20A5303i), Web Inspector is enabled in Safari's Advanced menu. Do we need to do some additional updates like rebuilding app with Xcode 14 or build that we currently have in AppStore should work without any modifications?

Hello, I have used WKWebview inside my tableview cell and given constraint inside my xib file. I am loading html text in webview which i get from server side in api and i have taken webview height constraint property for update height on did finish delegate method. It's not working proper and not giving proper height and on scroll every-time it's rendering with different height. My requirement is i want to display math equations and html content on webview with dynamic height of cell. I have done research and tried everything but it's not working. I am using below code for update webview height. func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {     webView.evaluateJavaScript("document.readyState", completionHandler: { (ready, error) in       if ready != nil {         DispatchQueue.main.asyncAfter(deadline: .now()) {           webView.evaluateJavaScript("document.body.scrollHeight") { [weak self] (result, _) in             guard let self = self, let result = result as? Double else { return }             self.webViewHeightConstraint.constant = CGFloat(result)             self.webView.updateConstraints()            }         }       }     })   }     Please help me to solve this issue. Thank you

Hello, We are running a complex web application built with React and related ecosystem. this web application is essentially a PWA and it is offline first. So, It relies heavily on service worker, indexDB database, cache storage, local storage etc. We are running this web application inside a WKWebView which resides in a native iOS App. We have noticed that WKWebView is highly unreliable when it is running such a complex web app. some of the behaviours noticed are only blank screen is shown with no content loaded from the url when url is pointed to different location (say uat, qa, prod environments) in the same wkwebview at run time, it causes data corruption as part of indexdb. it seems that it is not keeping different sets of data for different urls. when registering newer version of service workers, wkwebview errors out and can not proceed with new registrations does not always show a target page when a react app programmatically navigates to different locations within the web app. I am interested in knowing from fellow iOS developers that have you previously experienced above with WKWebView? is WKWebView a good option for running such a web application or SFSafariView is the better alternative? thank you Dilip

I just published a wkwebview app. But the app is only compatible with ios 15.0 and above. Please tell me, how can I update my app to make it compatible with older ios versions?

WWDC22 "What's new in WKWebView"  https://developer.apple.com/videos/play/wwdc2022/10049/?time=470 inspect and debug it yourself in third-party browsers on iOS, When I say third-party browsers, I mean on iOS16, you can use third-party browsers ，like use chrome browsers to debug my website？ thinks！

Only one particular URL does not load in the webview. Every other URL works. Not able to trace the issue but the console logs indicate the following error. Can anyone help around with this please?
