Swift & Parse - Empty PFFile

Question

I'm using Parse and MongoDB for my app, and I have a problem concerning PFFile. I would like to save an empty PFFile on the server. Indeed, the user doesn't have to send a picture but in an other way, it's possible.

I would like to set a default PFFile which is null.

    let imageFile: PFFile?

if previewImg.image != nil {
             // Send pic to server after converting to FILE and compression
             let imageData = UIImageJPEGRepresentation(previewImg.image!, 0.5)
             imageFile = PFFile(name: "step.jpg", data: imageData!)
          } else {
             imageFile = ""
          }

          object["stepImg"] = imageFile

This is my code. And my error is "cannot assign value of type string to type PFFile".

Do you have an idea about how I can do that ?

Answer 1

You declare a PFFile? so your variable can a PFFile or nil

This is the corrected code

let imageFile: PFFile?

if let previewImage = previewImg.image {
    // Send pic to server after converting to FILE and compression
    let imageData = UIImageJPEGRepresentation(previewImage, 0.5)
    object["stepImg"] = PFFile(name: "step.jpg", data: imageData!)
}
