Implementing Button in side menu - swift

Question

can someone Help me with fixing this. I want this code to work such as when I click the Home button on the side menu, it should take me to the Main View("This is the Main View"). I have tried using presenting sheets, however, presenting sheet doesn't look realistic. When the Home button is tapped, everything should disappear and only the Home Screen should come up with the side menu. I have tried writing up this code, however, I couldn't make the home button work. The codes are as below:
import SwiftUI
import Foundation
import Combine
struct Home: View {
#State var showMenu = false
#EnvironmentObject var userSettings: UserSettings
var body: some View {
let drag = DragGesture()
.onEnded {
if $0.translation.width < -100 {
withAnimation {
self.showMenu = false
}
}
}
return NavigationView {
GeometryReader {
geometry in
ZStack(alignment: .leading) {
MainView(showMenu: self.$showMenu)
.frame(width: geometry.size.width, height: geometry.size.height)
.offset(x: self.showMenu ? geometry.size.width/2 : 0)
.disabled(self.showMenu ? true : false)
if self.showMenu {
MenuView()
.frame(width: geometry.size.width/2)
.transition(.move(edge: .leading))
}
}
.gesture(drag)
}
.navigationBarTitle("Pay Data", displayMode: .inline)
.navigationBarItems(leading: (Button(action: {
withAnimation {
self.showMenu.toggle()
}
}){
Image(systemName: "line.horizontal.3")
.imageScale(.large)
}
))
}
}
}
struct MainView: View {
#Binding var showMenu: Bool
#EnvironmentObject var userSettings: UserSettings
var body: some View {
Text("This is Main View")
}
}
struct Home_Previews: PreviewProvider {
static var previews: some View {
Home()
.environmentObject(UserSettings())
}
}
//This is the Menu View. The Home Button is located in this view.
import SwiftUI
import Combine
import Foundation
struct MenuView: View {
#EnvironmentObject var userSettings: UserSettings
#State var showMenu = false
#State var Homevariable = false
var body: some View {
VStack(alignment: .leading) {
Button(action: {
UserDefaults.standard.set(false, forKey: "status")
}) {
(Text(Image(systemName: "rectangle.righthalf.inset.fill.arrow.right")) + (Text("Home")))
}
}
.padding()
.frame(maxWidth: .infinity, alignment: .leading)
.background(Color(red: 32/255, green: 32/255, blue: 32/255))
.edgesIgnoringSafeArea(.all)
}
}
struct MenuView_Previews: PreviewProvider {
static var previews: some View {
MenuView()
.environmentObject(UserSettings())
}
}
//This is the another view. I want the side Menu to appear on this as well, so when I press the Home button it takes me to the Main View("This is the Main View")
import SwiftUI
struct Calculation: View {
var body: some View {
Text("Hello, World!")
}
}
struct Calculation_Previews: PreviewProvider {
static var previews: some View {
Calculation()
}
}

Here you go. You are basically rebuilding a navigation logic, so in MainView you have to switch between the screens and put the side menu over it:
(PS: you can do without GeometryReader)
struct ContentView: View {
#State private var showMenu = false
#State private var selected: SelectedScreen = .home
var body: some View {
NavigationView {
ZStack {
// show selected screen
switch selected {
case .home:
MainView()
.disabled(self.showMenu ? true : false)
case .screen1:
OtherView(screen: 1)
case .screen2:
OtherView(screen: 2)
}
// put menu over it
if self.showMenu {
MenuView(showMenu: $showMenu, selected: $selected)
.transition(.move(edge: .leading))
}
}
.navigationBarTitle("Pay Data", displayMode: .inline)
// .navigationBarItems is deprecated, use .toolbar
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
withAnimation {
self.showMenu.toggle()
}
} label: {
Image(systemName: "line.horizontal.3")
.imageScale(.large)
}
}
}
}
}
}
enum SelectedScreen {
case home
case screen1
case screen2
}
struct MenuView: View {
#Binding var showMenu: Bool
#Binding var selected: SelectedScreen
var body: some View {
HStack {
VStack(alignment: .leading, spacing: 24) {
Button {
selected = .home
showMenu = false
} label: {
Label("Home", systemImage: "rectangle.righthalf.inset.fill.arrow.right")
}
Button {
selected = .screen1
showMenu = false
} label: {
Label("Screen 1", systemImage: "1.circle")
}
Button {
selected = .screen2
showMenu = false
} label: {
Label("Screen 2", systemImage: "2.circle")
}
}
.padding()
.frame(maxHeight: .infinity)
.background(Color(red: 32/255, green: 32/255, blue: 32/255))
Spacer()
}
}
}
struct MainView: View {
var body: some View {
Text("This is Main View")
.font(.largeTitle)
}
}
struct OtherView: View {
let screen: Int
var body: some View {
Text("Other View: Screen \(screen)")
.font(.largeTitle)
}
}
