How to make Sheet toggle and the navigate to a View - swift

Question

I have 3 Views A, BSheet, C.
When I click on a button inside A View, B Sheet becomes visible. I have a button in B Sheet. I want to press a button in BSheet View to close/toggle BSheet and then navigate to C View. Any ideas how I can accomplish that?
A.swift
struct A: View{
#State var displayBSheet = false
var body: some View{
NavigationView{
VStack{
Button(action: {self.displayBSheet.toggle()}){
Text("Navigate to BSheet")
}.sheet(isPresented: $displayBSheet){
BSheet()
}
NavgiationLink(destination: C()){
Text("Navigate To C")
}
}
}
}
}
BSheet.swift
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
struct MainView: View {
var body: some View {
Button(action:{
self.presentationMode.wrappedValue.dismiss()//This only sheet but I want to navigate to C View also
}){
Text("Close sheet and navigate to struct C")
}
}
}
C.swift
struct C: View {
var body: some View {
Text("C")
}
}

I cleaned up your codes for a good working one:
import SwiftUI
struct ContentView: View {
var body: some View {
HomeView()
}
}
struct HomeView: View {
#State var homeView: Bool = false
#State var displayViewB: Bool = false
#State var displayViewC: Bool = false
var body: some View{
ZStack {
VStack {
HStack {
Text("Home").font(Font.largeTitle.bold()).padding()
Spacer()
}
Spacer()
}
VStack {
Button(action: { homeView = true; displayViewB = true }) {
Text("open ViewB")
}
.sheet(isPresented: $homeView) {
if displayViewB
{
ViewB(homeView: $homeView, displayViewB: $displayViewB, displayViewC: $displayViewC)
}
if displayViewC
{
ViewC(homeView: $homeView, displayViewC: $displayViewC)
}
}
}
}
.onChange(of: homeView) { _ in
if displayViewB == false && displayViewC == true {
DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {homeView = true}
}
else if displayViewB == false && displayViewC == false {
homeView = false
}
}
}
}
struct ViewB: View {
#Binding var homeView: Bool
#Binding var displayViewB: Bool
#Binding var displayViewC: Bool
var body: some View {
Button(action:{
displayViewB = false
displayViewC = true
homeView = false
}){
Text("close ViewB and open Viewc")
}
}
}
struct ViewC: View {
#Binding var homeView: Bool
#Binding var displayViewC: Bool
var body: some View {
Button(action:{
displayViewC = false
homeView = false
}){
Text("close ViewC go to HomeView")
}
}
}

You can do this simple - in onDismiss of sheet
struct A: View{
#State var displayBSheet = false
#State var displayCSheet = false // << this !!
var body: some View{
NavigationView{
VStack{
Button(action: {self.displayBSheet.toggle()}){
Text("Navigate to BSheet")
}.sheet(isPresented: $displayBSheet, onDismiss: {
self.displayCSheet = true // << here !!
}){
BSheet()
}
NavgiationLink(destination: C(), isActive: $displayCSheet){ // << here !!
Text("Navigate To C")
}
}
}
}
}
