I have image loaded from UIImagePickerController into UIImageView

I need to convert the image into string to send it to the server

This is my code but it gives an error

var imageData:String = "";
        if let unwrappedImage = profileImage.image {
            let imageNSData : NSData = UIImageJPEGRepresentation(unwrappedImage, 1.0)!;
            imageData =  (NSString(data:imageNSData, encoding:NSUTF8StringEncoding) as String?)!
        }

I am getting the following exception 

fatal error: unexpectedly found nil while unwrapping an Optional value

can any one help please

    You can't convert the image's `NSData` to an `NSString` like that since the data doesn't represent the UTF-8 encoding a string. Do some research on converting an image's data to a base64 encoded string. – rmaddy Apr 16 '16 at 00:49

Convert the data information of a image to a string , you will get a very very very long string, why not loaded the data to the server. Alamofire can do it easily, just see the uploading file part.
