I've solved this problem using 99% pure SwiftUI on iOS 14. That's my implementation:

import SwiftUI

 struct ContentView: View {

    @State private var showtextFieldToolbar = false
    @State private var text = ""

    var body: some View {
    
        ZStack {
            VStack {
                TextField("Write here", text: $text) { isChanged in
                    if isChanged {
                        showtextFieldToolbar = true
                    }
                } onCommit: {
                    showtextFieldToolbar = false
                }
                .textFieldStyle(RoundedBorderTextFieldStyle())
                .padding()
            }
        
             VStack {
                Spacer()
                if showtextFieldToolbar {
                    HStack {
                        Spacer()
                        Button("Close") {
                            showtextFieldToolbar = false
                            UIApplication.shared
                                    .sendAction(#selector(UIResponder.resignFirstResponder),
                                            to: nil, from: nil, for: nil)
                        }
                        .foregroundColor(Color.black)
                        .padding(.trailing, 12)
                    }
                    .frame(idealWidth: .infinity, maxWidth: .infinity,
                           idealHeight: 44, maxHeight: 44,
                           alignment: .center)
                    .background(Color.gray)   
                }
            }
        }
    }
}

 struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
