How can i detect collision in Sprite Kit using Swift?

This is my code

func didBeginContact(contact: SKPhysicsContact) {

    let contactMask = contact.bodyA.categoryBitMask | contact.bodyB.categoryBitMask

    switch (contactMask){

    case BodyType.ball.toRaw() & BodyType.hole.toRaw():

        println("HEY")

    default :
        return
    }

}

//it prints nothing

//the declarations:

func addHole(#size : CGSize) {

    let actionMoveDown = SKAction.moveToY(CGRectGetMidY(self.frame)-500, duration: 4.7)
    let hole = shapedHoles()
    let UT = UTIL()
    var position:CGFloat


    let randomPosition = UT.randomNumberWith(Min: 1, Max: 3)

    switch randomPosition{
    case 1:
        position = CGRectGetMidX(self.frame)
    case 2:
        position = CGRectGetMidX(self.frame)+size.width

    default:
        position = CGRectGetMidX(self.frame)-(size.width)

    }



    var createdHole = hole.createHoleAtPosition(position: CGPointMake(position ,CGRectGetMaxY(self.frame) + (size.height/2)),size: size )//CGSizeMake(CGRectGetMaxX(self.frame)/3 - 10, 70)

    createdHole.physicsBody = SKPhysicsBody(rectangleOfSize: createdHole.frame.size)
    createdHole.physicsBody?.categoryBitMask = BodyType.hole.toRaw()
    createdHole.physicsBody?.contactTestBitMask = BodyType.ball.toRaw()
    createdHole.physicsBody?.affectedByGravity = false
    createdHole.physicsBody?.dynamic = false


    lastHolePosition = randomPosition

    createdHole .runAction(actionMoveDown)

    self.addChild(createdHole)



}

func addSphere(){
    let mainCharacterController = circle()
    let character: (SKNode) = mainCharacterController.createCircleAtPosition(position: CGPointMake(CGRectGetMidX(self.frame), CGRectGetMinY(self.frame)+100))


    character.physicsBody = SKPhysicsBody(circleOfRadius: character.frame.size.height/2)
    character.physicsBody?.categoryBitMask = BodyType.ball.toRaw()
    character.physicsBody?.contactTestBitMask = BodyType.hole.toRaw()
    character.physicsBody?.affectedByGravity = false
    character.physicsBody?.dynamic = false


    self.addChild(character)


}
