How would I create a UIAlertView in Swift?

How to Create a UIAlertView in Swift: A Quick and Easy Guide! 📱💬

So, you want to create a UIAlertView in Swift, huh? 🤔 It's a handy tool for displaying important messages or prompts to the user. But hey, we understand that syntax errors can be a real bummer! 😩

Don't worry, though! We've got your back! In this guide, we'll walk you through the process of creating a UIAlertView step by step, including some common issues you might stumble upon. Let's dive right in! 💪

The Problem 🤦‍♂️

Based on our reader's question, it seems like they're facing the following error:

Could not find an overload for 'init' that accepts the supplied arguments

This error usually occurs when we pass incorrect arguments to the initializer function. But fret not, we'll figure it out! 💡

The Solution 🎉

To create a UIAlertView in Swift, we need to follow a specific syntax. Let's take a closer look at the provided code snippet and fix any issues:

let button2Alert: UIAlertView = UIAlertView(title: "Title", message: "message",
                     delegate: self, cancelButtonTitle: "OK", otherButtonTitles: nil)

Now, the problem lies in how we're trying to call the show() method. You see, in Swift, UIAlertView has been deprecated, and we should use UIAlertController instead. 😮

Here's how we can modify the code to use UIAlertController:

let alertController = UIAlertController(title: "Title", message: "message", preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alertController, animated: true, completion: nil)

Voila! 🎊 By making this modification, we're using the UIAlertController class to create the alert view and present it to the user. Ain't that cool? 😎
