ios-webview version

[AndreKR]

The user agent

Mozilla/5.0 (iPhone; CPU iPhone OS 15_3_1 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148

and other similar user agents are detected as:

{
	"name": "ios-webview",
	"version": "605.1.15",
	"os": "iOS",
	"type": "browser"
}

I'm assuming that this user agent corresponds to what caniuse.com calls "Safari on iOS" (Example) and that the 15_3_1 in the user agent is the actual useful version information?

I don't know what the version number 605.1.15 means, but it doesn't seem particularly useful as I haven't seen any other value than 605.1.15.

Edit: The same can be said about instagram.
