I'm new to SpriteKit. When I drag and drop "Color Sprite" from object library to make a new node. It gives the correct size (as you can see in the image below). Here the parent is the main scene not the blue one.

But when I change the parent node from the main scene to any other node (like blue one in my case) the new node gets larger however it's width and height remain same (shown below).
EDIT:
I'm running Xcode 7 beta 3.
