SKSpriteNode drag movement by touch - xcode

Question

I'm trying to drag a SKSpirteNode around the screen by touching the screen. But I want to be able to do a constant movement of the Sprite, currently my code only moves the sprite to the location of my touch but if I hold and move the sprite will not follow. Moreover I don't want to "have" to touch the SKSpriteNode to activate the movement, I want to touch anywhere on the screen and to have a movement response from that SKSpriteNode.
Here is my current code:
class GameScene: SKScene {
override func didMoveToView(view: SKView) {
// SpriteNode I want to drag around
basket = SKSpriteNode(texture: basketTexture)
self.addChild(basket)
}
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
/* Called when a touch begins */
var nodeTouched = SKNode()
var currentNodeTouched = SKNode()
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
nodeTouched = self.nodeAtPoint(location)
basket.position = location
}
Thank you any help appreciated.

I solved this by using the func touchesMoved instead of touchesBegan and works perfectly and smoothly. here is the final code:
class GameScene: SKScene {
override func didMoveToView(view: SKView) {
// SpriteNode I want to drag around
basket = SKSpriteNode(texture: basketTexture)
self.addChild(basket)
}
override func touchesMoved(touches: NSSet, withEvent event: UIEvent) {
/* Called when a touch begins */
var nodeTouched = SKNode()
var currentNodeTouched = SKNode()
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
nodeTouched = self.nodeAtPoint(location)
basket.position = location
}
