How do I present errors consistently in UIKit with Swift?

Presenting errors consistently in UIKit with Swift is crucial for a seamless user experience. This can be achieved through custom error handling functions and by using UIAlertController to display error messages. Here’s how you can implement a unified error presentation mechanism across your iOS apps.

By creating a standardized error handling method, you ensure that errors are communicated effectively, making it easier for users to understand what went wrong and how to proceed. Below is a Swift example demonstrating how to handle errors consistently using a simple function.

import UIKit extension UIViewController { func displayError(message: String) { let alert = UIAlertController(title: "Error", message: message, preferredStyle: .alert) alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil)) self.present(alert, animated: true, completion: nil) } } // Usage in ViewController class MyViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Simulating an error let errorOccurred = true if errorOccurred { displayError(message: "An unexpected error has occurred.") } } }
