ios - swift game doesn't work as i want it to -

i creating game random shapes fall down , each shape has number , , number represent number of clicks user has on image , image removed , score increased 1 , have problem when images created , , when run of images work fine , when click on number of times has on , gets removed want , when same image created , when click on it prints out msg have put "the user has not clicked on image " have put in default in switch stattment in touchended method , :

    override func touchesended(touches: nsset, withevent event: uievent) {          touch: anyobject in touches {              let location = touch.locationinnode(self)              switch(nodeatpoint(location)){              case self.circle:                 if circlecount == 1{                     circle.removefromparent()                     println("score")                     circlecount = 0                 }              case self.rectangle:                 if rectanglecount == 2{                     println("score")                     rectangle.removefromparent()                     rectanglecount = 0                 }              case self.square:                      if squarecount == 3{                     println("score")                     square.removefromparent()                     squarecount = 0                 }              case self.polygon:                 if polygoncount == 4{                     println("score")                     polygon.removefromparent()                     polygoncount = 0                 }               default:                 println("user didnt click on image")          }      }  } 

and thats 1 of functions displays 1 of images:

func createrectangle(a: cgfloat){      rectangle = skspritenode()     rectangle = skspritenode(imagenamed: "rectangle")     rectangle.size = cgsize(width: 150, height: 150)     rectangle.physicsbody = skphysicsbody(rectangleofsize: rectangle.size)     rectangle.physicsbody?.dynamic = true     rectangle.physicsbody?.allowsrotation = false     rectangle.position = cgpoint(x: a, y: self.frame.size.height)     self.addchild(rectangle) } 

and there function generates random number display shapes randomly.

check out updated code:
