How to make multiline message text view in SwiftUI

import SwiftUI
import UIKit

struct MessageTextField: View {
    let placeholder: String
    @Binding var text: String
    @Binding var isEditing: Bool

    @State private var height: CGFloat = 100

    var body: some View {
        UITextViewWrapper(
            text: $text,
            isEditing: $isEditing,
            height: $height

        .frame(height: height)
        .background(placeholderView, alignment: .topLeading)
    }

    var placeholderView: some View {
        Group {
            if text.isEmpty {
                Text(placeholder)
                    .foregroundColor(Asset.textSecondary.color)
                    .font(.system(size: 16))
                    .padding(.leading)
            }
        }
    }
}

    func makeCoordinator() -> Coordinator {
        Coordinator(parent: self)
    }
