Starting from iOS 16.1 WKWebView can't load pages with SharedWorker, if an app doesn't have "com.apple.developer.web-browser" entitlement. Samples: https://mdn.github.io/dom-examples/web-workers/simple-shared-worker/ https://vc.ru The NetProcess terminates the WebProcess, and renders the whole WKWebView crashed. In case the "com.apple.developer.web-browser" entitlement is present it works fine. The issue can be reproduced on iOS 16.1 with a basic WKWebView, or in apps: Google - https://apps.apple.com/ru/app/google/id284815942 Yandex - https://apps.apple.com/ru/app/яндекс-с-алисой/id1050704155 The issue can NOT be reproduced in: Chrome - https://apps.apple.com/ru/app/chrome-браузер-от-google/id535886823 Yandex Browser - https://apps.apple.com/ru/app/яндекс-браузер/id483693909 or on any iOS version prior 16.1

Clarification: The app doesn't crash. Only the WebProcess crashes. There is this message in the log. [Process] 0x136010a18 - [pageProxyID=6, webPageID=7, PID=57025] WebPageProxy::processDidTerminate: (pid 57025), reason=RequestedByNetworkProcess And: com.apple.WebKit.Networking Received an invalid message 'WebSharedWorkerObjectConnection_FetchScriptInClientReply' from WebContent process 5, requesting for it to be terminated.

This issue is also affecting Salesforce customers on iOS. This is used in multiple apps. Ref https://trailblazer.salesforce.com/issues_view?title=white-screen-when-logging-into-mobile-publisher-for-experience-cloud-app-on-ios-16-1&Id=a1p4V000002fqzg
