How to upload an image using Alamofire SwiftyJSON to a JSON swift 3

Question

I'm trying to send an image to my API using alamofire and SwiftyJSON. I've been trying some different ways to do that, however no success so far. The last one I tried is the base64EncodedString and is not working. I have the variable styleStrength as a JSON.

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]){

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {

        self.profileImage.image = image
        self.profileImage.isHidden = false
        self.profileImage.contentMode = UIViewContentMode.scaleAspectFill
        let imageData = UIImagePNGRepresentation(image)
        let base64String = imageData!.base64EncodedString(options: [])
        var styleStrengthData = JobSeekerBuildProfile.loadJobSeekerBuildProfile()
        styleStrengthData["Personal_Style"]["profile_pic_file"].stringValue = base64String + ".jpg"
        JobSeekerBuildProfile.storeJobSeekerBuildProfile(j: styleStrengthData)

    }else{
        //error message
    }

    self.dismiss(animated: true, completion: nil)
}

As return I have a really huge image name but the API doesn't update.

Dont use base64.Please try to upload image using multi-part. — Rishil Patel, Mar 23 '18 at 04:49

Try to use the UIImageJPEGRepresentation instead of UIImagePNGRepresentation.

Replace these lines in your code

let imageData = UIImagePNGRepresentation(image)
let base64String = imageData!.base64EncodedString(options: [])
styleStrengthData["Personal_Style"]["profile_pic_file"].stringValue = base64String + ".jpg"

with the

 let imageData = UIImageJPEGRepresentation(image,0.5)! as NSData
 let strBase64ProfilePic = imageData.base64EncodedString()   
 styleStrengthData["Personal_Style"]["profile_pic_file"].stringValue = base64String
