Base64 String creating extension for UIImage

base64.swift

extension UIImage {
    
    enum Quality {
        case Best, High, Medium, Low
    }
    
    
    func toBase64(quality: Quality) -> String {

        var imageData: NSData
        
        switch quality {
        case .Best:
            imageData = UIImagePNGRepresentation(self)
            break
        case .High:
            imageData = UIImageJPEGRepresentation(self, 0.75)
            break
        case .Medium:
            imageData = UIImageJPEGRepresentation(self, 0.5)
            break
        case .Low:
            imageData = UIImageJPEGRepresentation(self, 0.25)
            break
        default:
            break
        }
        
        return imageData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
    }
}

Nice.
