Swift - Fix print issue and pass variables to a class to finish drawing

My code needs two fix:

1) It is not printing within the functional call

2) pass the variable so the class can draw correctly

Code sample below

public func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {

print ("my test")

var x1 = 50

let y1 = 100

let x2 = 10

let y2 = 10

let x3 = 200

let y3 = 200

let x4 = 350

let y4 = 100

}

class DrawView: UIView {

override func draw(_ rect: CGRect) {

let context = UIGraphicsGetCurrentContext()

context?.setLineWidth(10.0)

context?.setStrokeColor([login to view URL])

context?.move(to: CGPoint(x: x1, y: y1))

context?.addLine(to: CGPoint(x: x2, y: y2))

context?.strokePath()

let context2 = UIGraphicsGetCurrentContext()

context2?.setLineWidth(10.0)

context2?.setStrokeColor([login to view URL])

context2?.move(to: CGPoint(x: x3, y: y3))

context2?.addLine(to: CGPoint(x: x4, y: y4))

context2?.strokePath()

}

}
