Dynamic Height For TextView In SwiftUI

In modern messaging apps, the text input area plays a vital role in user experience. With SwiftUI, it’s now possible to create a TextView with dynamic height, allowing the input field to grow or shrink based on the user’s content.

When the keyboard appears, the message view can automatically scroll to the latest message, delivering a smooth and intuitive experience. This behavior mimics the interaction style of popular apps like iMessage, WhatsApp, and Telegram, where users can type freely without being constrained by a fixed-size input box.

Built entirely with SwiftUI, this feature requires no UIKit integration, making it lightweight and easy to adopt in any SwiftUI-based project.
