Step-by-Step Implementation of multi-line editable textual content area in SwiftUI

Step 1: Open Xcode and choose “Create a brand new Xcode undertaking.“. Select “App” below the iOS tab.Identify your undertaking and ensure “SwiftUI” is chosen for the Person Interface.

            ZStack(alignment: .topLeading) {
                RoundedRectangle(cornerRadius: 14, fashion: .steady)
                    .strokeBorder(Colour.pink.opacity(0.6), lineWidth: 1)
                if multiLineText.isEmpty {
