Customize UISlider Height - Programmatically Created - swift

Question

How do you create a custom height for a Slider when the slider has been created programmatically?
The answers to this similar question explain how to do it when the Slide is setup with a Storyboard. What if you aren't using a Storyboard and the slider is set up along these lines programmatically? Thanks!
let slider: UISlider = {
let slider = UISlider()
slider.minimumValue = 1
slider.maximumValue = 7
slider.value = 1
slider.maximumTrackTintColor = UIColor.red
slider.minimumTrackTintColor = UIColor.green
slider.thumbTintColor = UIColor.blue
slider.isContinuous = true
slider.translatesAutoresizingMaskIntoConstraints = false
return slider
}()

You'll need to create a custom slider, and override trackRect(forBounds bounds: CGRect) -> CGRect
class CustomSlider: UISlider {
let trackHeight: CGFloat = 12 //desired track width, in points
override func trackRect(forBounds bounds: CGRect) -> CGRect {
let track = super.trackRect(forBounds: bounds)
return CGRect(x: track.origin.x, y: track.origin.y, width: track.width, height: trackHeight)
}
}
and change your implementation to use this
let slider: CustomSlider = {
let slider = CustomSlider()
slider.minimumValue = 1
slider.maximumValue = 7
slider.value = 1
slider.maximumTrackTintColor = UIColor.red
slider.minimumTrackTintColor = UIColor.green
slider.thumbTintColor = UIColor.blue
slider.isContinuous = true
slider.translatesAutoresizingMaskIntoConstraints = false
return slider
}()
