Description Ali Juma 2022-12-22 06:57:21 PST 
WKWebViewConfiguration's applicationNameForUserAgent only allows setting a single application name, that is used in both desktop and mobile mode when generating a user agent string.

However, this doesn't work for browsers (like Chrome on iOS) that want to use a different application name in desktop mode vs mobile mode.

Safari on iOS solves this problem using SPI to set the application name for desktop mode (-[WKWebPagePreferences _setApplicationNameForUserAgentWithModernCompatibility]), and non-Safari browsers would benefit from having API that achieves the same functionality.
