Porting of Cocos2d Class to iOS SpriteKit

Hi, I have a simple Cocos2d class (about 300 lines) which makes shattering effect programmatically to any sprite as shown in the attached video file. I want this class be ported to SpriteKit. I prefer Objective-C, but Swift is also OK if neccessary. You can find the original class and Cocos2d project by simply googling "ShatteredSprite cocos2d". Shattering effect should be customizable as the original file. Also shattering should be similar to the one shown in video and be random. I want the job done in a week. I want to emphasise that shattering should be done programmatically, I am not interested in png sequences created in After effects of some other animation program.
