Content View

struct ContentView: View {
    @State private var title = String()
    @State private var name = String()
    @State private var people: [Person]? = nil
    @State private var showAddField: Bool = false
    var body: some View {
        Form {
          List {
                if let unwrappedPeople = people {
                    ForEach(unwrappedPeople, id: \.id) { person in
                        HStack {
                            Text(person.title)
                            Spacer()
                            Text(person.name)
                        }
                    }
                } else {
                    EmptyView()
                }
                if showAddField {
                    Button(action: addRow) {
                        HStack {
                            Spacer()
                            Text("Add Row")
                            Spacer()
                        }
                    }
                } else {
                    HStack(alignment: .center) {
                        TextField("Title", text: $title)
                        TextField("Name", text: $name)
                        HStack {
                            Button(action: { <br>
                                self.submit(title: self.title, name: self.name)
                             }) {
                                Text("Submit")
                            }
                            .buttonStyle(BorderlessButtonStyle())
                            }
                        }
                    }
                }
            }
        }
    }

Person Structure

struct Person: Identifiable {
let id = UUID()
var title: String
var name: String
}

Add Row and Submit Functions

private func addRow() { 
self.showAddField = false 
} 

private func submit(title: String, name: String) { 
if self.people?.isEmpty == nil { 
self.people = [Person(title: self.title, name: self.name)] 
} else { 
self.people?.append(Person(title: self.title, name: self.name)] 
} 
self.title = String() 
self.name = String() 
self.showAddField = true 
}
