Best method to draw image on top of another image

Question

I am working on SwiftUI app where I have to draw a transparent image over another image, then overlay it with a text.

currently i am achieving this with UIGraphicsBeginImageContextWithOptions but it's taking more time as i have an array of nearly 1700 images . Is there any other alternative we can use instead of UIGraphicsBeginImageContextWithOptions?

for mdl in bottomImage{
    for img in Constants.episodesFrames  {
        autoreleasepool {
            imageName += 1
            let text = mdl!.text
            let imageSelected = mdl?.image.scaleImageToSize(newSize: CGSize(width: 660, height: 700))
            let topNew = UIImage(named: img)
            UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
            imageSelected!.draw(in: CGRect(origin: .zero, size: newSize))
            topNew!.draw(in: CGRect(origin: .zero, size: newSize))
            let font=UIFont(name: "JosefinSans-SemiBold", size: 35)!
            let text_style=NSMutableParagraphStyle()
            text_style.lineBreakMode = .byWordWrapping
            text_style.alignment=NSTextAlignment.center
            let text_color=UIColor(named: "videoText")
            let attributes=[NSAttributedString.Key.font:font, NSAttributedString.Key.paragraphStyle:text_style, NSAttributedString.Key.foregroundColor:text_color]
            let text_y=((newSize.height)/1.19)
            let text_rect=CGRect(x: 0, y: text_y, width: newSize.width-30, height: newSize.height)
            text.draw(in: text_rect, withAttributes: attributes as [NSAttributedString.Key : Any])
            //Conditions for changing the topImage
            if imageName >= 391 && imageName <= 440{
                let frameCenter = UIImage(named:Constants.repeatFrames[imageName-391])
                frameCenter?.draw(in: CGRect(origin: .zero, size: newSize))
            }else if imageName >= 638 && imageName <= 687{
                let frameCenter = UIImage(named:Constants.repeatFrames[imageName-638])
                frameCenter?.draw(in: CGRect(origin: .zero, size: newSize))
            }else if imageName >= 885 && imageName <= 934{
                let frameCenter = UIImage(named:Constants.repeatFrames[imageName-885])
                frameCenter?.draw(in: CGRect(origin: .zero, size: newSize))
            }else if imageName >= 1132 && imageName <= 1181{
                let frameCenter = UIImage(named:Constants.repeatFrames[imageName-1132])
                frameCenters?.draw(in: CGRect(origin: .zero, size: newSize))
            }else if imageName >= 1379 && imageName <= 1428{
                let frameCenter = UIImage(named:Constants.repeatFrames[imageName-1379])
                frameCenter?.draw(in: CGRect(origin: .zero, size: newSize))
            }
            let newImage = UIGraphicsGetImageFromCurrentImageContext()
            UIGraphicsEndImageContext()
            saveImageTempDirectory(image: newImage!, imageName: "Image\(imageName).jpg")
        }
    }
