extension UIImage {
    var data: Data? { return UIImagePNGRepresentation(self) }
    var highestQualityJPEGData: Data? { return UIImageJPEGRepresentation(self, 1.0)  }
    var highQualityJPEGData: Data?    { return UIImageJPEGRepresentation(self, 0.75) }
    var mediumQualityJPEGData: Data?  { return UIImageJPEGRepresentation(self, 0.5)  }
    var lowQualityJPEGData: Data?     { return UIImageJPEGRepresentation(self, 0.25) }
    var lowestQualityJPEGData: Data?   { return UIImageJPEGRepresentation(self, 0.0)  }
}

Time is your!!!
