Friend: Interesting. That seems like a really useful feature for SwiftUI apps.
Me: Absolutely. It's important for user experience because it makes it easier for users to dismiss the keyboard when it's no longer needed. Plus, it creates a more consistent experience since it follows the same conventions that other iOS apps use.
