This hides the unreachable code warning from the compiler. Although almost as
ugly as hiding it by wrapping inside "#ifdef QT_DEBUG”
QString enumValue;
QDebug(&enumValue) << this->d_ptr->trackerFileSend.state();
qDebug("%s", enumValue.toLatin1().data());

Xcode 7.2.
In an attempt to reduce Xcode's nagging to accept it’s *many* recommended
project settings, I have the following warning flags added to my qmake project.
There are still another half-dozen recommended project settings that I have
not figured out what the associated flags are.
The issue only shows up in release build. The following warnings are added to
my qmake project for all builds.
# Silence warnings on OSX ( I do not get these on the OSX build VM? Same
XCode 6.4? )
