Tooltip fade out delay in OS X 10.11.1 and Xcode 7.1.1

Does anyone know where I can set the delay/time how long does the fade out effect in Xcode 7.1.1 on OS X 10.11.1 need to hide the displayed tooltip? When I search for the term defaults find tooltip, I only get WebKitShowsToolTipOverTruncatedText and WebKit2ShowsToolTipOverTruncatedText from *com.apple.iTunes* and *com.apple.appstore*. With defaults find delay I get more results, but nothing about I looking for.
