Remove Subview not working

I have add a subview into an UIImageView and i try to remove the subview by calling the removeFromSuperview function but it is not working and the subview is still there...Any idea?

Below is my code:

 var path = CGMutablePath()
        path.move(to: CGPoint(x: 127.5, y: 13.5))
        path.addLine(to: CGPoint(x: 165.0, y: 13.5))
        path.addLine(to: CGPoint(x: 165.0, y: 51.5))
        path.addLine(to: CGPoint(x: 127.5, y: 51.5))
        path.closeSubpath()

        var shape = CAShapeLayer()
        shape.path = path
        shape.opacity = 0.5
        shape.lineWidth = 3.0
        shape.fillColor = UIColor(hue: 0.786, saturation: 0.15, brightness: 0.89, alpha: 1.0).cgColor

        let pathClick = path.contains(location)

    if pathClick == true
            {
                let avgX = (127.5 + 127.5 + 165 + 165) / 4
                let avgY = (13.5 + 13.5 + 51.5 + 51.5) / 4
                let centerLocation = CGPoint(x: avgX, y: avgY)

                bubble.frame = CGRect(x: 0, y: 0, width: 15, height: 15)
                bubble.center = centerLocation
                mapImageView.layer.addSublayer(shape)
                mapImageView.addSubview(bubble)
                handleMore()
            }
            else
            {
                bubble.removeFromSuperview()
                print("working")
            }

it is not removing, because that is not view - you have added before. That is a another instance. You may access previous one from mapImageView.subviews, that is array of all subviews of your mapImageView. Identify which one is yours to remove, and use identifiedView.removeFromSuperview. You may use tags to identify your subviews. Another way is to remember your view when you are adding it as subview, and remove that view from superView. Anyway, you need to identify right subview.

I have only two solutions without the broad spectrum of the whole code.

  1. You could just hide the buble and essentially it wouldn't be there at all.
  2. mapImageView contains the subview of buble, maybe remove buble from mapImageView.
