Swipe gesture doesn't work with banners over navigation bar position

[synergetica11]

The problem is in 430 line in TSMessageView.m

Gesture direction is never set for TSMessageNotificationPositionNavBarOverlay

You should set it like
[gestureRec setDirection:(self.messagePosition == (TSMessageNotificationPositionTop || TSMessageNotificationPositionNavBarOverlay) ?
UISwipeGestureRecognizerDirectionUp :
UISwipeGestureRecognizerDirectionDown)];
