get a string from UIImage in swift

Question

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

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.
