MacOS:向Swift中的图像添加文本覆盖

import CoreGraphics

let image = UIImage(named: "image.jpg")
UIGraphicsBeginImageContextWithOptions(image.size, false, 0.0)

image.draw(in: CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height))

let textLayer = CATextLayer()
textLayer.string = "Hello, World!"
textLayer.foregroundColor = UIColor.white.cgColor
textLayer.backgroundColor = UIColor.black.cgColor
textLayer.alignmentMode = .center
textLayer.frame = CGRect(x: 0, y: 0, width: image.size.width, height: image.size.height)

textLayer.render(in: UIGraphicsGetCurrentContext()!)

let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
