how to use this extension

Please hlp

@AkAyush
I'm using this and another small extension for UIImage:

extension UIImage {
    func imageWithSize(scaledToSize newSize: CGSize) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
        self.draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
        let newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return newImage
    }
}

How to use:

func showAlert() {
    let alertController = UIAlertController()
    let action = UIAlertAction(title: "Title", style: .default) { (action: UIAlertAction!) in
        // ...
        }
        
    let image = UIImage(named: "Photo")
    if let image = image?.imageWithSize(scaledToSize: CGSize(width: 30, height: 30)) {
        action.setValue(image, forKey: "image")
    }
    
    alertController.addAction(action)
    self.present(alertController, animated: true, completion: nil)
}
