[Interest] How prevent "Code will never be executed" when compiling "qDebug() << enumvar" ?

#ifdef QT_DEBUG // Fix iOS Clang warning "Code will never be executed"

qDebug() << "TapAndHoldGesture: " << tapAndHold->state();

#endif


Is there an easier way to hide this from the iOS compiler without turning off CLANG_WARN_UNREACHABLE_CODE ?

    Q_CLANG_WARN_UNREACHABLE_CODE.name = CLANG_WARN_UNREACHABLE_CODE
    Q_CLANG_WARN_UNREACHABLE_CODE.value = YES
    QMAKE_MAC_XCODE_SETTINGS += Q_CLANG_WARN_UNREACHABLE_CODE


The following does not generate  "Code will never be executed” but is harder to read since I must lookup the enum value.

qDebug(“TapAndHoldGesture: %i “, (int)tapAndHold->state());

Thanks,

-Ed
