Detect a swipe gesture over a Raycast

Hi Guys.

Ok, I have a 3D scene where there are certain objects. This objects makes an action using Raycast. Now, I want to be able to move the Camera when I swipe over the scene, but if I start the swipe over one object that responds to a Raycast, it always execute the Raycast action. That's isn't what I want. What I want is that Swipe actions prevail over Raycast actions. Any suggestions?
