Subject [jira] [Commented] (CB-11889) Add easy way to detect WKWebView
Date Thu, 29 Sep 2016 10:33:20 GMT


Ashley Gullen commented on CB-11889:

Oh, right. But given how different WKWebView is regarding its same-origin policy - i.e. you
can't AJAX local files - it seems reasonable to expect a lot of apps to have to make code
changes when running on WKWebView. Accordingly it seems reasonable for Cordova to have a built-in
way to indicate WKWebView. Shouldn't this be a core feature?

I have tried to persuade Apple to add a feature to identify WKWebView for the same reasons,
but they rejected the request.

> There is no clear and easy way to detect WKWebView from the user agent string or from
any Cordova properties, AFAIK.
> Previous solutions said to test for window.indexedDB. This is no longer present on iOS
10's WKWebView. Our engine Construct 2 used to rely on this to work around the different security
model/featureset of WKWebView, but since iOS 10 changed it, all our games using WKWebView
are broken.
> I want to add some other way to detect it, but it is all undocumented and I could end
up relying on something that changes and breaks everything again.
> To prevent this problem happening again there should be something like "isWKWebView"
