How do I add text to my MKOverLayRenderer - swift

Question

I am trying to build a custom MKOverlayRenderer subclass which will display an image and text presented on top of some type of subview based on this answer. At my current stage of implementing this I have gotten the image to appear on the map but now I am trying to add text over the image.
The text is appearing upside down and flipped on top of the image. The image appears to be oriented correctly using the same rectangle and same context. What am I doing wrong how do I go about implementing this?
This is the code pertaining to drawing the text:
UIGraphicsPushContext(context);
// ...
UIGraphicsPushContext(context);
UIColor.black.setStroke()
context.setLineWidth(1)
context.stroke(rect.insetBy(dx: 0.5, dy: 0.5))
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center
let attributes = [NSAttributedString.Key.paragraphStyle : paragraphStyle,
NSAttributedString.Key.font : UIFont.systemFont(ofSize: 100.0),
NSAttributedString.Key.foregroundColor : UIColor.black]
"\(rect.size)".draw(in: rect, withAttributes: attributes)
UIGraphicsPopContext();
Class in its Entirety
class CustomOverlayView:MKOverlayRenderer{
var overlayImage:UIImage
init(overlay:MKOverlay,image:UIImage){
self.overlayImage = #imageLiteral(resourceName: "DSC00042")
super.init(overlay: overlay)
}
override func draw(_ mapRect: MKMapRect, zoomScale: MKZoomScale, in context: CGContext) {
super.draw(mapRect, zoomScale: zoomScale, in: context)
guard let imageReference = overlayImage.cgImage else { return }
var rect = self.rect(for: overlay.boundingMapRect)
context.scaleBy(x: 1.0, y: -1.0)
context.translateBy(x: 0.0, y: -rect.size.height)
context.draw(imageReference, in: rect)
UIGraphicsPushContext(context);
// ...
UIGraphicsPushContext(context);
UIColor.black.setStroke()
context.setLineWidth(1)
context.stroke(rect.insetBy(dx: 0.5, dy: 0.5))
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center
let attributes = [NSAttributedString.Key.paragraphStyle : paragraphStyle,
NSAttributedString.Key.font : UIFont.systemFont(ofSize: 100.0),
NSAttributedString.Key.foregroundColor : UIColor.black]
"\(rect.size)".draw(in: rect, withAttributes: attributes)
UIGraphicsPopContext();
}
}
