Couldn't make a particle follow a path in spriteKit - objective-c

Question

This is the animation in XCode SKEmitter editor (I want to achieve this on the iPhone) :
This is the animation on the iPhone (I don't want this animation):
Using this code:
let sparkEmmiter = SKEmitterNode(fileNamed: "fireflies.sks")
self.addChild(sparkEmmiter) // self is a SKScene
var circle: CGPathRef? = nil
circle = CGPathCreateWithEllipseInRect(CGRectMake(400, 200, 200, 200), nil)
let followTrack = SKAction.followPath(circle!, asOffset: false, orientToPath: true, duration: 3.0)
let followTrackForever = SKAction.repeatActionForever(followTrack)
//sparkEmmiter.runAction(followTrackForever)
sparkEmmiter.particleAction = followTrackForever;
This is the emitter settings:
I tried both runAction and particleAction by referring to this question, but it doesn't work as I wanted it to...
-----------------Update----------------------------------------------
Tried the solution mentioned by hamobi (still doesn't work) :
//If I were you:
// 1) I'd make a sprite and
let texture = SKTexture(imageNamed: "spark")
let mySprite = SKSpriteNode(texture: texture)
self.addChild(mySprite)
// 2) add the emitter in your first example as a child.
let sparkEmmiter = SKEmitterNode(fileNamed: "fireflies.sks")
mySprite.addChild(sparkEmmiter)
// 3) I'd set the emitters targetNode to the scene.
sparkEmmiter.targetNode = self
// 4) Then I'd just animate the sprite itself in an arc.
var circle: CGPathRef? = nil
circle = CGPathCreateWithEllipseInRect(CGRectMake(400, 200, 200, 200), nil)
let followTrack = SKAction.followPath(circle!, asOffset: false, orientToPath: true, duration: 3.0)
let followTrackForever = SKAction.repeatActionForever(followTrack)
//sparkEmmiter.runAction(followTrackForever)
sparkEmmiter.particleAction = followTrackForever;

Got it! Thx to hamobi :D this is the result :D:D

If I were you I'd make a sprite and add the emitter in your first example as a child. I'd set the emitters targetNode to the scene. Then I'd just animate the sprite itself in an arc.
EDIT:
okay so the main thing you were missing is that you should forget about using particleAction. Make mySprite run the followTrackForever action.
heres my code
//If I were you:
// 1) I'd make a sprite and
let texture = SKTexture(imageNamed: "spark")
let mySprite = SKSpriteNode(texture: texture)
mySprite.position = CGPoint(x: self.size.width/2, y: self.size.height/2)
self.addChild(mySprite)
// 2) add the emitter in your first example as a child.
let sparkEmmiter = SKEmitterNode(fileNamed: "fireflies.sks")
mySprite.addChild(sparkEmmiter)
// 3) I'd set the emitters targetNode to the scene.
sparkEmmiter.targetNode = self
// 4) Then I'd just animate the sprite itself in an arc.
var circle: CGPathRef? = nil
circle = CGPathCreateWithEllipseInRect(CGRectMake(100, 200, 200, 200), nil)
let followTrack = SKAction.followPath(circle!, asOffset: false, orientToPath: true, duration: 3.0)
let followTrackForever = SKAction.repeatActionForever(followTrack)
mySprite.runAction(followTrackForever)
