SKShapeNode scales a fill texture by default, instead of repeating the pattern. This snippet extends SKShapeNode to support setting a tiled fill-texture.

SKShapeNode Tiled Fill Texture

import SpriteKit

extension SKShapeNode {
    func setTiledFillTexture(imageName: String, tileSize: CGSize) {
        let targetDimension = max(self.frame.size.width, self.frame.size.height)
        let targetSize = CGSizeMake(targetDimension, targetDimension)
        let targetRef = UIImage(named: imageName).CGImage

        UIGraphicsBeginImageContext(targetSize)
        let contextRef = UIGraphicsGetCurrentContext()
        CGContextDrawTiledImage(contextRef, CGRect(origin: CGPointZero, size: tileSize), targetRef)
        let tiledTexture = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        self.fillTexture = SKTexture(image: tiledTexture)
    }
}

I share my experiences to help others save some time. 😄
First, try not to get confused with fillTexture and strokeTexture. If you are drawing not a closed shape, like a path, then there is nothing to fill.
Also it looks to me like the texture image must have dimensions of 2^n. If I used different sizes the result is just a black fill.

Thank you @RolandColored 👍

can i cover ball with my texture image using this code?
