How do I internationalize date/number formats using FormatStyle?

Internationalizing date and number formats in Swift can be efficiently achieved using the `FormatStyle` protocol. This flexibility allows developers to localize their app's presentation based on the user’s locale settings.

Here's a simple example of how to format dates and numbers using `FormatStyle`:

// Example of formatting a date and number in Swift import Foundation let date = Date() let number = 1234567.89 // Format date to a localized string let dateFormatter = DateFormatter() dateFormatter.dateStyle = .full dateFormatter.locale = Locale.current let formattedDate = dateFormatter.string(from: date) // Format number to a localized string let numberFormatter = NumberFormatter() numberFormatter.numberStyle = .decimal numberFormatter.locale = Locale.current let formattedNumber = numberFormatter.string(from: NSNumber(value: number)) ?? "" print("Formatted Date: \(formattedDate)") print("Formatted Number: \(formattedNumber)")
