✅ GreenAlert

A really useful way to use UIAlertController, using extensions.

Let's say you want to show a basic alert.

Rather than writing this:

let alertController = UIAlertController(title: "Title", message: "Message")

let okAction = UIAlertAction(title: "OK", style: .default) { _ in
    ()
}

alertController.addAction(okAction)

present(alertController, animated: true, completion: nil)

You can write this:

UIAlertController.showBasicAlert("Title", message: "Message")

Not a big enough difference for you? Okay, let's suppose you've got a more complicated one.

Instead of THIS:

let alertController = UIAlertController(title: "Title", message: "Message")

let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { _ in
    // handle Cancel
}

let okAction = UIAlertAction(title: "OK", style: .default) { _ in
    // handle OK
}

alertController.addAction(cancelAction)
alertController.addAction(okAction)

present(alertController, animated: true, completion: nil)

Why not have this:

UIAlertController.showOKCancelAlert("Title", message: "Message") { confirmed in
    // Handle OK or Cancel based on `confirmed` being true or false
}

Or, if you're using Swift Concurrency:

if await UIAlertController.showOKCancelAlert("Title", message: "Message") {
    // User tapped OK!
}

Now, isn't that nicer?

But wait, there's more.

With GreenAlert, you're granted all sorts of UIAlertController superpowers, including the following:

• Customizations galore
  • SAFELY set alert style to action sheet, using enums to enforce the presence of source information.
    • I say "safely" here because you can easily crash an iPadOS app by creating an .actionSheet and forgetting to set the popoverPresentationController's sourceView, sourceRect, or barButtonItem. These crashes don't occur on iPhones, and are therefore easy to miss if you don't test throughly. Using GreenAlert eliminates these crashes.
  • Custom button action icons, via SF Symbols (preferred) or a UIImage
• Show prompts for values
  • With all the customizations listed above, but also including customizable:
    • preset text
    • placeholder
    • keyboard type
• Add progress bars to alert controllers

…And even more!

So give it a shot! 😁
