SKPhysicsJoint remove connecting line between node

Question

I have this code where I am connecting two nodes, everything working as expected. Question is that I want to remove the connecting blue line between nodes (attached image for ref). How should I do that?

   //This function creates a player sprite node and place it on screen 

   func addPlayer () {
        player = SKShapeNode(circleOfRadius: 30)
        player.position = CGPoint(x: playableArea.midX, y: playableArea.midY - 600)
        player.fillColor = UIColor.black
        player.strokeColor = UIColor.white
        player.lineWidth = 4
        player.physicsBody = SKPhysicsBody(circleOfRadius: 30)
        player.physicsBody?.affectedByGravity = false
        player.physicsBody?.isDynamic = false
        player.name = "characterColor"
        addChild(player)
    }

//This function creates second node and attach it as tail of player node and also joint player and tail node
    func addTail () {
        tail = SKShapeNode(circleOfRadius: 25)
        tail.position = CGPoint(x: player.position.x, y: player.position.y - 60)
        tail.physicsBody = SKPhysicsBody(circleOfRadius: 25)
        tail.fillColor = UIColor.black
        addChild(tail)
        let joint = SKPhysicsJointPin.joint(withBodyA: player!.physicsBody!, bodyB: tail.physicsBody!, anchor: player.position)

        joint.shouldEnableLimits = true
        joint.lowerAngleLimit = 0
        joint.upperAngleLimit = 0
        joint.frictionTorque = 0.1
        physicsWorld.add(joint)
    }

Answer 1

in your GameViewController you have view.showPysics = true this is used for debugging your physics object but you need to turn it off when you don't wan to see it anymore

you also have framerat eand node count set to true as well

view.showsFPS = true 
view.showsNodeCount = true

just turn them to false to not display them anymore
