How to get UserAgent for WKWebView without initializing UIWebView or WKWebView?

Question

I know we can initialize a UIWebView or WKWebView then inject JavaScript to get the value of navigator.userAgent , however that requires the initialization of UIWebView , which takes much time . Is there a way to get UserAgent faster?

Answer 1

If you need the exact userAgent string, you can ignore this answer.

If, however, you are interested in the info encoded inside the userAgent string, you can get most/all of them with other APIs... eg you get the device type with UIDevice.current.model ; the browser type is Safari/Mobile Safari (didn't check what's the exact string but this value is unlikely to change); the platform obviously is iOS; etc.
