you have the ") <- Error Here }" the wrong way around. It should be:

Code Block         navigationBarItems(trailing:
                            Button(action: {
                                print("Hello")
                            }) {
                                Image(systemName: "square.and.pencil")
                                    .resizable()
                                    .frame(width: 50, height: 50)
                            }) <- Error not Here

Here's the corrected code:

import SwiftUI

struct MainView: View {
    var body: some View {
        NavigationView {
            Text("")
                .navigationTitle("Home")
                .navigationBarItems(trailing:
                    Button(action: {
                        print("Hello")
                    }) {
                        Image(systemName: "square.and.pencil")
                            .resizable()
                            .frame(width: 50, height: 50)
                    }
                )
        }
    }
}

struct MainView_Previews: PreviewProvider {
    static var previews: some View {
        MainView()
    }
}

I've moved the navigationBarItems modifier inside the NavigationView block and added the closing parenthesis for the Button modifier. This should resolve the "Expected expression" error you were encountering.
