I’m going to make my app to talk whatever I wat it to say. To do that, we need `AVSpeechSynthesizer`

You can check out my article [AVSpeechSynthesizer](https://hackmd.io/@rizzyD/avspeechsynthesizer) to know more about it.

import SwiftUI
//Remember to import this framework
import AVFoundation

struct ContentView: View {
    
    @State private var text: String = ""
    
    var body: some View {
        
        VStack{
            
            Text(text)
                .padding()
                .font(.title)
                .foregroundColor(Color.red)

            TextField("Type here...", text: $text)          
                .padding()
                
            Button("Speak") {
                
                //create a new AVSpeechSynthesizer
                let synthesizer = AVSpeechSynthesizer()
                //I want to make all the sound stop before I make it speak anything
                synthesizer.stopSpeaking(at: .immediate)

                //setup utterance and make the speech content as the data typed in TextField
                let utterance = AVSpeechUtterance(string: text)
                //speech language
                utterance.voice = AVSpeechSynthesisVoice(language: "en-US")
                //tone
                utterance.pitchMultiplier = 1
                //speech speed
                utterance.rate = 0.4
                //play 
                synthesizer.speak(utterance)
                
            }
            .buttonStyle(.borderedProminent)
            .buttonBorderShape(.capsule)
        }
        
    }
    
}

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