Does anyone know how to transform (rotate,scale,skew) SpriteKit nodes using transformation matrices. couldn't find any support for this in the Spritekit API.

3I'm not sure about it specifically but you can add an SKEffectNode to a node and the effects that can be run are any of the CIFilters (or your own) that are available on iOS. – Fogmeister Sep 23 '15 at 14:42

As mentioned by Fogmeister, you can use an SKEffectNode with a CIFilter. The following works on iOS:
// Label
let label = SKLabelNode(text: "Hello world")
// Transform
let transform = CGAffineTransformMake(1, 0.5, 0, 1, 0, 0)
// CIFilter
let transformFilter = CIFilter(name: "CIAffineTransform")!
let val = NSValue(CGAffineTransform: transform)
transformFilter.setValue(val, forKey: "inputTransform")
// Effect node
let transformNode = SKEffectNode()
transformNode.filter = transformFilter
// Add label as child on effect node
transformNode.addChild(label)
scene.addChild(transformNode)
See more on affine transform in Apple's documentation.
