I was expecting one ScreenCapture DeviceType.
What is the benefit of bringing these in finer grained types?

strange message but I guess it is fine.

A port may not support all types of screen capture, so WebKit will need to signal the UA so it can prompt the user with only the supported types. Further, once the user chooses a screen, application, window, or tab to share, the UA will have to pass the ID of the "display surface" as well as the type.

For the record, this should have been ios(WK_IOS_TBA).

I landed

https://trac.webkit.org/changeset/226513

to fix the iOS build with the public SDK.
