Drawing Smooth Curves - Methods Needed

Question

How do you smooth a set of points in an iOS drawing app WHILE MOVING? I have tried UIBezierpaths but all I get are jagged ends where they intersect, when I just shift the po

Swift:

        let point1 = CGPoint(x: 50, y: 100)

        let point2 = CGPoint(x: 50 + 1 * CGFloat(60) * UIScreen.main.bounds.width / 375, y: 200)

        let point3 = CGPoint(x: 50 + 2 * CGFloat(60) * UIScreen.main.bounds.width / 375, y: 250)

        let point4 = CGPoint(x: 50 + 3 * CGFloat(60) * UIScreen.main.bounds.width / 375, y: 50)

        let point5 = CGPoint(x: 50 + 4 * CGFloat(60) * UIScreen.main.bounds.width / 375, y: 100)


        let points = [point1, point2, point3, point4, point5]

        let bezier = UIBezierPath()


        let count = points.count

        var prevDx = CGFloat(0)
        var prevDy = CGFloat(0)

        var prevX = CGFloat(0)
        var prevY = CGFloat(0)

        let div = CGFloat(7)


        for i in 0..
