Summary:
An SKShapeNode presented in an SKScene with its path property set to a CGPathRef created with CGPathCreateWithEllipseInRect is drawn with blurry edges compared to the exact same path drawn in a UIView's drawRect: method.

Steps to Reproduce:
Provided a SpriteKit project with the template code, create an SKShapeNode and modify it as such:

SKShapeNode *node = [[SKShapeNode alloc] init];
node.path = CGPathCreateWithEllipseInRect(rect, NULL);
SKColor *color = [SKColor redColor];
node.fillColor = color;

Then position it and add it as a child of the SKScene provided by the template.

Expected Results:
An ellipses drawn within the CGRect and drawn with an anti aliased edge that fulfill the capabilities of CoreGraphics.

Actual Results:
An ellipses drawn within the CGRect, but with ugly, blurry edge.

Regression:
This is the case for both antiAliased = YES and antiAliased = NO.

Notes:
See sample project.
