Swift UIImage extension for base64 conversion

Extensions.swift

// MARK: - UIImage (Base64 Encoding)

public enum ImageFormat {
    case PNG
    case JPEG(CGFloat)
}

extension UIImage {
    
    public func base64(format: ImageFormat) -> String {
        var imageData: NSData
        switch format {
        case .PNG: imageData = UIImagePNGRepresentation(self)
        case .JPEG(let compression): imageData = UIImageJPEGRepresentation(self, compression)
        }
        return imageData.base64EncodedStringWithOptions(.allZeros)
    }
}

thanks :)

Very nice ty

wonderful thank you

For who looking for Swift 4.2 version

public enum ImageFormat {
    case png
    case jpeg(CGFloat)
}

extension UIImage {
    public func toBase64(format: ImageFormat) -> String? {
        var imageData: Data?

        switch format {
        case .png:
            imageData = self.pngData()
        case .jpeg(let compression):
            imageData = self.jpegData(compressionQuality: compression)
        }

        return imageData?.base64EncodedString()
    }
}

Is it possible to have this in the latest swift and Xcode I guess 12.3 for me but for macOS not for iOS , as no matter where I search I always find code for iOS only with the UIImage and macOS has NSImage . In my case I need to get the image from a Image View and save it as base64

Thanks in advance

enum ImageFormat
{
case png
case jpeg(CGFloat)
}

extension UIImage
{

  func image2String64(_ format: ImageFormat) -> String?
  {
        var imageData: Data?
        
        switch format
        {
          case .png:
                imageData = UIImagePNGRepresentation(self)
          case .jpeg(let compression):
                imageData = UIImageJPEGRepresentation(self, compression)
        }
        
        return imageData?.base64EncodedString()
  }

}
