How to convert Image to Base64 in SwiftUI?

Question

I'm trying to convert an Image object to Base64 and then send it to a server using HTTP request.

Note: Image ≠ UIImage

This is my code:

struct MyView: View { 
    @State var image:Image? = nil // I want to convert this Image to Base64 when a button is clicked

    var body: some View {
        Button(action: {
            // ...
        }) {
            Image(systemName: "paperplane.fill")
        }
    }
}

You say: “Note: Image ≠ UIImage”. True, but a SwiftUI Image isn’t anything of use. If you want to do something with the data, you need a UIImage. Just say `UIImage(systemName: "paperplane.fill")!` and away you go. — matt, Nov 29 '19 at 02:43
"and away you go". Unless you're using a platform that doesn't support UIImage, like macOS. — Drew, Jan 10 '23 at 20:37

   func convertImageToBase64(image: UIImage) -> String? {
    let imageData = image.jpegData(compressionQuality: 1)
    return imageData?.base64EncodedString(options: 
    Data.Base64EncodingOptions.lineLength64Characters)
   }

 func convertImageToBase64(_ image: UIImage) -> String {
    let imageData: NSData = UIImageJPEGRepresentation(image, 0.7)! as NSData
    let strBase64 = imageData.base64EncodedString(options: .lineLength64Characters)

    return strBase64
 }

I hope it will help you.

I tried it with this: self.convertImageToBase64(self.image) and I got this error: Cannot convert value of type 'Image?' to expected argument type 'UIImage' – J. Raji Nov 29 '19 at 02:31
`self.convertImageToBase64(UIImage(systemName: "paperplane.fill")!)` – matt Nov 29 '19 at 02:45
You have to use UIImage instead of Image – Marcin Kaczmarzyk Nov 30 '19 at 12:18
So, How to convert Image to UIImage? – J. Raji Dec 09 '19 at 22:58
Image is not UIImage so this is not helpful – ColinMasters Sep 18 '20 at 21:07
