Hi, I am trying to generate a Mandelbrot fractal using the draw function to draw CGRects of points included in set. The code doesn't work and I get a circle instead. Any help?

This is the class for my custom view:

import UIKit

class View: UIView {

```
var pointsToDraw = [Point]()
override func draw(_ rect: CGRect) {
for point in pointsToDraw {
point.color.setFill()
UIRectFill(point.coordinates)
}
}
```

}

this is my complex number struct:

struct complexNumber {

```
var real:Double = 0.0
var imaginary:Double = 0.0
mutating func add(This complexNumberToAdd:complexNumber){
real += complexNumberToAdd.real
imaginary += complexNumberToAdd.imaginary
}
mutating func squared() {
let tempReal = real
let tempImaginary = imaginary
real = (tempReal * tempReal) - (tempImaginary * tempImaginary)
imaginary = 2 * tempReal * tempImaginary
}
func modulus () -> Double {
return sqrt(real * real + imaginary * imaginary)
}
mutating func iterate (With C:complexNumber) {
squared()
add(This: C)
}
```

}

and finally, this is my mandelbrot class:

class Mandelbrot {

```
var points = [Point]()
var xMin:Double, xMax:Double, yMin:Double, yMax:Double
var parentView:View
var Z:complexNumber, C:complexNumber
var maxIterations:Int
var currentIteration:Int
var xPixelValue:Double {
return (xMax - xMin) / Double(parentView.bounds.maxX)
}
var yPixelValue:Double {
return (yMax - yMin) / Double(parentView.bounds.maxY)
}
init (InView view:View) {
xMin = -2.0
xMax = 2.5
yMin = -2
yMax = 2.5
Z = complexNumber()
C = complexNumber()
maxIterations = 50
currentIteration = 0
parentView = view
for i in 1...Int(parentView.bounds.maxX) {
for j in 1...Int(parentView.bounds.maxY) {
Z.real = 0
Z.imaginary = 0
currentIteration = 0
C.real = xMin + (Double(i) * xPixelValue)
C.imaginary = yMax - (Double(j) * yPixelValue)
while (currentIteration < maxIterations)
{
Z.iterate(With: C)
currentIteration += 1
if Z.modulus() > 2 {
break
}
else
{
points.append(Point(PointX: i, PointY: j))
}
}
}
}
dispatchPoints()
}
func dispatchPoints() {
parentView.pointsToDraw.removeAll()
for point in points {
parentView.pointsToDraw.append(point)
}
}
```

}

Thank you,
