This isn't incorrect style for a NS_OPTIONS typedef.  Style for functions is being applied in the wrong context. 

> ERROR: Source/WebKit2/UIProcess/API/Cocoa/WKWebViewPrivate.h:134:  Missing spaces around =  [whitespace/operators] [4]

This isn't incorrect style for property declarations. This matches the style of the line directly above it. Style for assignment operator is being applied in the wrong context.

How to do this?  I did not find a component by the name of "check-webkit-style" when selecting the component for a new bug.

The gtk-wk2 build failure is irrelevant.  It was caused by http://trac.webkit.org/changeset/166553.

Looks great! I can imagine a version of this API where there is no delegate, and the “find” and “count” methods take completion handler blocks, but as SPI this is a great start.

No need to qualify String with WTF:: since WTFString.h, which you’re including, says “using WTF::String”.

Why not call this _viewForFindUI? “Host” has other meanings, and isn’t a term we normally use to describe the role of a view.

No need for the space between the > >.

Ditto.

> Source/WebKit2/UIProcess/Cocoa/FindClient.mm:40
> +RetainPtr<id <_WKFindDelegate> > FindClient::delegate()

Ditto.

> Source/WebKit2/UIProcess/Cocoa/FindClient.mm:45
> +void FindClient::setDelegate(id <_WKFindDelegate> delegate)

Ditto.

I tried removing WTF:: and it resulted in a compile time error in WebPageProxy.  I think the compiler is assuming API::String if the WTF:: is not present to clarify which String class. 

thanks for reviewing.

Yeah it is needed to resolve the API::String vs WTF::String ambiguity.
