如何将元数据永久保存到UIImage？

import ImageIO

func saveImageWithMetadata(image: UIImage, metadata: [String: Any], outputPath: String) {
    guard let cgImage = image.cgImage else {
        return
    }
    
    let options = [kCGImageDestinationLossyCompressionQuality: 1.0] as CFDictionary
    let destinationURL = URL(fileURLWithPath: outputPath) as CFURL
    
    if let destination = CGImageDestinationCreateWithURL(destinationURL, kUTTypeJPEG, 1, nil) {
        CGImageDestinationAddImage(destination, cgImage, options)
        CGImageDestinationSetProperties(destination, metadata as CFDictionary)
        CGImageDestinationFinalize(destination)
    }
}

// 使用示例
let image = UIImage(named: "example.jpg")!
let metadata = CGImageSourceCopyPropertiesAtIndex(image.cgImageSource!, 0, nil) as! [String: Any]
let outputPath = "path/to/save/image.jpg"

saveImageWithMetadata(image: image, metadata: metadata, outputPath: outputPath)
