I'm trying the Quick Look feature of the new Xcode 5 to be able to see my images in the debugging pane but I'm getting this message that my images cannot be previewed with Quick Look, it says "Could not load Quick Look data for "image"", where "image" is the name of my variable. 

Does this happen because of the size of the image or is there any other thing to consider? My image's size is kind of big like (width=2448, height=1224)

Thanks!
