SwiftUI - Sheet Dismmis button not working - swift

I want to add a button on the top of my view that will be the "X" to close the sheet. I am unable to use presentationmode option. For some reason it isn't working. Can someone please let me know how I can add a button that shows an "X" on the top that if I click on will close this view. Your help is very much appreciated.
import SwiftUI
struct TopicsExperienceCards: View {
// #Environment(\.presentationMode) var presentationMode
let etype: EItype
var body: some View {
NavigationView{
/* Alernatively Page Layout View */
ScrollView (.vertical, showsIndicators: false) {
Rectangle()
.fill(Color(etype.accentcolor))
.frame(width: 300, height: 5)
.padding()
GroupBox {
TabView {
ForEach(etype.content1,id: \.self) {item in
VStack (alignment:.center, spacing:0){
Text(item)
.padding()
.frame(width:300, height:300, alignment:.center)
Divider()
Spacer()
Text("Room for an image")
Spacer()
Spacer()
}
} //foreach
} //: TABVIEW
.tabViewStyle(PageTabViewStyle())
.onAppear {
setupAppearance() }
} //end of GroupBox
// .padding()
.frame(width:350, height:650)
.clipShape(RoundedRectangle(cornerRadius: 25.0, style: .circular))
.shadow(radius: 5)
} //end of ScrollView
.edgesIgnoringSafeArea(.all)
} //end of Navigation view
}
}
/* Function for the black dots in pagination */
func setupAppearance() {
UIPageControl.appearance().currentPageIndicatorTintColor = .black
UIPageControl.appearance().pageIndicatorTintColor = UIColor.black.withAlphaComponent(0.2)
}
struct TopicsExperienceCards_Previews: PreviewProvider {
static let etypes: [EItype] = Bundle.main.decode("eibasestructure.json")
static var previews: some View {
TopicsExperienceCards(etype:etypes[1])
}
}

You can just pass in the Binding that you use to present the sheet to TopicsExperienceCards as well.
struct ContentView: View {
#State var isPresented = false
var body: some View {
Button("Present") {
isPresented = true /// set Binding to true to present
}
.sheet(isPresented: $isPresented) {
TopicsExperienceCards(isPresented: $isPresented) /// pass Binding here
}
}
}
struct TopicsExperienceCards: View {
#Binding var isPresented: Bool
var body: some View {
VStack {
HStack {
Spacer()
Button(action: {
isPresented = false /// set Binding back to false
}) {
Image(systemName: "xmark")
.padding()
}
}
Spacer()
}
}
}

Dismissing a SwiftUI sheet with a lot of navigation views

I have a button that opens up a Profile & Settings view in a sheet that has additional navigation views in it.
I am aware how to dismiss the sheet, however this method seems to not work with additional navigation views, as when I'm deeper into the navigation and I tap "Done" to dismiss the sheet, it only returns me back to the previous navigation view until I go back to the main Profile & Settings view.
The view with the button:
import SwiftUI
struct TodayView: View {
#State private var showSheet = false
var body: some View {
NavigationView {
ScrollView {
VStack(alignment: .leading) {
TodayTabDateComponent()
.padding(.top, -10)
ForEach(0 ..< 32) { item in
VStack(alignment: .leading) {
Text("Title")
Text("Description")
}
.padding(.vertical)
}
}
.frame(maxWidth: .infinity, alignment: .leading)
.padding(.horizontal)
}
.navigationTitle("Today")
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button(action: {
showSheet = true
}, label: {
Image(systemName: "person.circle.fill")
.foregroundColor(.primary)
})
.sheet(isPresented: $showSheet) {
ProfileAndSettingsView()
}
}
}
}
}
}
struct TodayView_Previews: PreviewProvider {
static var previews: some View {
TodayView()
}
}
The Profile & Settings view:
import SwiftUI
struct ProfileAndSettingsView: View {
#Environment(\.presentationMode) var presentationMode
var body: some View {
NavigationView {
VStack {
List {
Section {
NavigationLink {
UserProfileView()
} label: {
HStack(alignment: .center) {
Image("avatar")
.resizable()
.aspectRatio(contentMode: .fit)
.clipShape(Circle())
.frame(width: 60, height: 60)
VStack(alignment: .leading) {
Text("Name Surname")
.font(.title2)
.fontWeight(.bold)
Text("Profile Settings, Feed Preferences\n& Linked Accounts")
.font(.caption)
}
}
}
.padding(.vertical, 6)
} }
.listStyle(.insetGrouped)
.navigationTitle("Profile & Settings")
.navigationBarTitleDisplayMode(.inline)
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
Button {
presentationMode.wrappedValue.dismiss()
} label: {
Text("Done")
}
}
}
}
}
}
}
struct ProfileAndSettingsView_Previews: PreviewProvider {
static var previews: some View {
ProfileAndSettingsView()
}
}
I have looked into the issue but couldn't find any working solutions.
Is your issue here that you're applying the .sheet to the Button inside the Toolbar? I think you need to apply it to the NavigationView itself?
import SwiftUI
struct TodayView: View {
#State private var showSheet = false
var body: some View {
NavigationView {
....
}
.navigationTitle("Today")
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button(action: {
showSheet = true
}, label: {
Image(systemName: "person.circle.fill")
.foregroundColor(.primary)
})
}
}
.sheet(isPresented: $showSheet) {
ProfileAndSettingsView()
}
}
}
}
If you're targeting iOS15 or higher don't use presentationMode use #Environment(\.isPresented) private var isPresented instead this will perform the action that you want.
presentationMode was deprecated and replaced by isPresented and dismiss
I believe that presentationMode performs a similar action as dismiss does which according to Apple Docs (on the dismiss)
If you do this, the sheet fails to dismiss because the action applies to the environment where you declared it, which is that of the detail view, rather than the sheet. In fact, if you’ve presented the detail view in a NavigationView, the dismissal pops the detail view the navigation stack.
The dismiss action has no effect on a view that isn’t currently presented. If you need to query whether SwiftUI is currently presenting a view, read the isPresented environment value.
If you're targeting a lower iOS version you can create your own key like so
struct SheetOpen: EnvironmentKey {
static var defaultValue: Binding<Bool> = .constant(false)
}
extension EnvironmentValues {
var sheetOpen: Binding<Bool> {
get { self[SheetOpen.self] }
set { self[SheetOpen.self] = newValue }
}
}
Where you have your sheet defined you do this
.sheet(isPresented: $showSheet) {
ProfileAndSettingsView()
.environment(\.sheetOpen, $showSheet)
}
Then you can use it like any other environment variable
#Environment(\.sheetOpen) var sheetOpen
To dismiss it you simply do this sheetOpen.wrappedValue.toggle()

SwiftUI: save the state of toggle and keep the animation

In SwiftUI, for this code to toggle the display of view:
#State var show = true
Button { withAnimation { show.toggle() }}
label: { Image(systemName: show ? "chevron.down" : "chevron.right") }
if show { ... }
The animation will be shown if the show is the #State variable.
However, I found that if show is changed to #AppStorage (so to keep the show state), the animation will not be shown.
Is there a way to keep the show state and also preserve the animation?
You can also replace the withAnimation {} with the .animation(<#T##animation: Animation?##Animation?#>, value: <#T##Equatable#>) modifier and then it seems to work directly with the #AppStorage wrapped variable.
import SwiftUI
struct ContentView: View {
#AppStorage("show") var show: Bool = true
var body: some View {
VStack {
Button {
self.show.toggle()
}
label: {
Rectangle()
.fill(Color.red)
.frame(width: self.show ? 200 : 400, height: 200)
.animation(.easeIn, value: self.show)
}
Rectangle()
.fill(Color.red)
.frame(width: self.show ? 200 : 400, height: 200)
.animation(.easeIn, value: self.show)
}
.padding()
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
EDIT: Following the comments, another solution
import SwiftUI
struct ContentView: View {
#State private var show: Bool
init() {
self.show = UserDefaults.standard.bool(forKey: "show")
// Or self._show = State(initialValue: UserDefaults.standard.bool(forKey: "show"))
}
var body: some View {
VStack {
Button {
withAnimation {
self.show.toggle()
}
}
label: {
Text("Toggle")
}
if show {
Rectangle()
.fill(Color.red)
.frame(width: 200 , height: 200)
}
}
.padding()
.onChange(of: self.show) { newValue in
UserDefaults.standard.set(newValue, forKey: "show")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}

Implementing Button in side menu

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)
}
}

How do I implement #EnvironmentObject for this custom full-screen modal setup?

My goal is to have custom modals present over an root view that is essentially a tabbed view. So, I wrapped the TabView in a ZStack and am using an ObservableOBject. But I don't feel I'm doing it the right way.
In my other file, I have the Custom modal "subviews" which has an enum, too, which I think is the right approach to take. But I cannot figure out how to dismiss a modal after it is visible.
It must be #EnvironmentObject, but I don't know what if anything to put in the scene delegate, etc. ("Hacking with Swift" is failing me here, although it's a great resource.)
My idea is that views from the tabbed view will have various buttons which present different modal views, populated later with data specific to say a user and set of fields for data entry.
Right now, I just want to understand how to present and dismiss them.
Here is my root view
import SwiftUI
struct ContentView: View {
#ObservedObject var modal = CustomModal()
var body: some View {
ZStack {
TabView {
ZStack {
Color.pink.opacity(0.2)
Button(action: {
withAnimation{
self.modal.visibleModal = VisibleModal.circle
}
}) {
Text("Circle").font(.headline)
}
.frame(width: 270, height: 64)
.background(Color.pink.opacity(0.5)).foregroundColor(.white)
.cornerRadius(12)
}
.tabItem{
VStack{
Image(systemName: "1.square.fill")
Text("One")
}
}.tag(1)
ZStack {
Color.blue.opacity(0.2)
Button(action: {
self.modal.visibleModal = VisibleModal.squircle
}) {
Text("Square").font(.headline)
}
.frame(width: 270, height: 64)
.background(Color.blue.opacity(0.5)).foregroundColor(.white)
.cornerRadius(12)
}
.tabItem{
VStack{
Image(systemName: "2.square.fill")
Text("Two")
}
}.tag(2)
}.accentColor(.purple)
VStack {
containedView()
}
}
}
func containedView() -> AnyView {
switch modal.visibleModal {
case .circle: return AnyView(CircleView())
case .squircle: return AnyView(SquircleView())
case .none: return AnyView(Text(""))
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
And here is my second file with the enum and "subview" modals
import SwiftUI
class CustomModal: ObservableObject {
#Published var visibleModal: VisibleModal = VisibleModal.none
}
enum VisibleModal {
case circle, squircle, none
}
struct CircleView: View {
var body: some View {
ZStack {
Color.pink.blur(radius: 0.4)
Circle().fill()
.frame(width: 300)
.foregroundColor(Color.white.opacity(0.75))
dismissButton()
}.edgesIgnoringSafeArea(.all)
}
}
struct SquircleView: View {
var body: some View {
ZStack{
Color.green.blur(radius: 0.4)
RoundedRectangle(cornerRadius: 48, style: .continuous)
.frame(width: 300, height: 300).foregroundColor(Color.white.opacity(0.75))
dismissButton()
}.edgesIgnoringSafeArea(.all)
}
}
struct dismissButton: View {
#ObservedObject var modal = CustomModal()
var body: some View {
VStack{
Spacer()
Button(action: {
self.modal.visibleModal = VisibleModal.none
}) {
Text("Dismiss").font(.headline)
}
.frame(width: 270, height: 64)
.background(Color.white.opacity(0.35)).foregroundColor(.white)
.cornerRadius(12)
.padding(.bottom, 44)
}
}
}
Are you just trying to pass your observable object to the new view?
func containedView() -> some View {
switch modal.visibleModal {
case .circle: return CircleView()
.environmentObject(self.modal)
case .squircle: return SquircleView()
.environmentObject(self.modal)
case .none: return Text("")
}
}
Unless I am misunderstanding the question.
Okay, after a lot of fiddling, it works.
Now my code is as follows.
Root view
struct ContentView: View {
#EnvironmentObject var isModalVisible: CustomModal
#ObservedObject var modal = CustomModal()
var body: some View {
ZStack {
TabView {
ZStack {
Color.pink.opacity(0.2)
Button(action: {
withAnimation{
self.isModalVisible.isModalVisible.toggle()
self.modal.currentModal = VisibleModal.circle
}
}) {
Text("Circle").font(.headline)
}
.frame(width: 270, height: 64)
.background(Color.pink.opacity(0.5)).foregroundColor(.white)
.cornerRadius(12)
}
.tabItem{
VStack{
Image(systemName: "1.square.fill")
Text("One")
}
}.tag(1)
ZStack {
Color.blue.opacity(0.2)
Button(action: {
self.isModalVisible.isModalVisible.toggle()
self.modal.currentModal = VisibleModal.squircle
}) {
Text("Square").font(.headline)
}
.frame(width: 270, height: 64)
.background(Color.blue.opacity(0.5)).foregroundColor(.white)
.cornerRadius(12)
}
.tabItem{
VStack{
Image(systemName: "2.square.fill")
Text("Two")
}
}.tag(2)
}.accentColor(.purple)
if self.isModalVisible.isModalVisible {
VStack {
containedView()
}
}
}
}
func containedView() -> AnyView {
switch modal.currentModal {
case .circle: return AnyView(CircleView())
case .squircle: return AnyView(SquircleView())
case .none: return AnyView(Text(""))
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView().environmentObject(CustomModal())
}
}
and the second file with the supporting views and classes and enums:
import SwiftUI
class CustomModal: ObservableObject {
#Published var isModalVisible = false
#Published var currentModal: VisibleModal = .none
}
enum VisibleModal {
case circle, squircle, none
}
struct CircleView: View {
#EnvironmentObject var env: CustomModal
var body: some View {
ZStack {
Color.pink.blur(radius: 0.4)
Circle().fill()
.frame(width: 300)
.foregroundColor(Color.white.opacity(0.75))
dismissButton()
}.edgesIgnoringSafeArea(.all)
}
}
struct SquircleView: View {
var body: some View {
ZStack{
Color.green.blur(radius: 0.4)
RoundedRectangle(cornerRadius: 48, style: .continuous)
.frame(width: 300, height: 300).foregroundColor(Color.white.opacity(0.75))
dismissButton()
}.edgesIgnoringSafeArea(.all)
}
}
struct dismissButton: View {
#EnvironmentObject var env: CustomModal
var body: some View {
VStack{
Spacer()
Button(action: {
self.env.isModalVisible.toggle()
print("TAPPED")
}) {
Text("Dismiss").font(.headline)
}
.frame(width: 270, height: 64)
.background(Color.white.opacity(0.35)).foregroundColor(.white)
.cornerRadius(12)
.padding(.bottom, 44)
}
}
}
It still can be refactored. I'm sure. I'd also be happy to hear any comments on how to improve it. But it seems to work.
NOTE: This code ContentView().environmentObject(CustomModal()) is put in the previewP{rovider code and in SceneDelegate.

Tabbar middle button utility function in SwiftUI

I'm trying to reproduce a "Instagram" like tabBar which has a "Utility" button in the middle which doesn't necessarily belong to the tabBar eco system.
I have attached this gif to show the behaviour I am after. To describe the issue. The tab bar in the middle (Black plus) is click a ActionSheet is presented INSTEAD of switching the view.
How I would do this in UIKit is simply use the
override func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {
print("Selected item")
}
Function from the UITabBarDelegate. But obviously we can't do this in SwiftUI so was looking to see if there was any ideas people have tried. My last thought would be to simply wrap it in a UIView and use it with SwiftUI but would like to avoid this and keep it native.
I have seen a write up in a custom TabBar but would like to use the TabBar provided by Apple to avoid any future discrepancies.
Thanks!
Edit: Make the question clearer.
Thanks to Aleskey for the great answer (Marked as correct). I evolved it a little bit in addition to a medium article that was written around a Modal. I found it to be a little different
Here's the jist.
A MainTabBarData which is an Observable Object
final class MainTabBarData: ObservableObject {
/// This is the index of the item that fires a custom action
let customActiontemindex: Int
let objectWillChange = PassthroughSubject<MainTabBarData, Never>()
var previousItem: Int
var itemSelected: Int {
didSet {
if itemSelected == customActiontemindex {
previousItem = oldValue
itemSelected = oldValue
isCustomItemSelected = true
}
objectWillChange.send(self)
}
}
func reset() {
itemSelected = previousItem
objectWillChange.send(self)
}
/// This is true when the user has selected the Item with the custom action
var isCustomItemSelected: Bool = false
init(initialIndex: Int = 1, customItemIndex: Int) {
self.customActiontemindex = customItemIndex
self.itemSelected = initialIndex
self.previousItem = initialIndex
}
}
And this is the TabbedView
struct TabbedView: View {
#ObservedObject private var tabData = MainTabBarData(initialIndex: 1, customItemIndex: 2)
var body: some View {
TabView(selection: $tabData.itemSelected) {
Text("First Screen")
.tabItem {
VStack {
Image(systemName: "globe")
.font(.system(size: 22))
Text("Profile")
}
}.tag(1)
Text("Second Screen")
.tabItem {
VStack {
Image(systemName: "plus.circle")
.font(.system(size: 22))
Text("Profile")
}
}.tag(2)
Text("Third Screen")
.tabItem {
VStack {
Image(systemName: "number")
.font(.system(size: 22))
Text("Profile")
}
}.tag(3)
}.actionSheet(isPresented: $tabData.isCustomItemSelected) {
ActionSheet(title: Text("SwiftUI ActionSheet"), message: Text("Action Sheet Example"),
buttons: [
.default(Text("Option 1"), action: option1),
.default(Text("Option 2"), action: option2),
.cancel(cancel)
]
)
}
}
func option1() {
tabData.reset()
// ...
}
func option2() {
tabData.reset()
// ...
}
func cancel() {
tabData.reset()
}
}
struct TabbedView_Previews: PreviewProvider {
static var previews: some View {
TabbedView()
}
}
Similar concept, just uses the power of SwiftUI and Combine.
You could introduce new #State property for storing old tag of presented tab. And perform the next method for each of your tabs .onAppear { self.oldSelectedItem = self.selectedItem } except the middle tab. The middle tab will be responsible for showing the action sheet and its method will look the following:
.onAppear {
self.shouldShowActionSheet.toggle()
self.selectedItem = self.oldSelectedItem
}
Working example:
import SwiftUI
struct ContentView: View {
#State private var selectedItem = 1
#State private var shouldShowActionSheet = false
#State private var oldSelectedItem = 1
var body: some View {
TabView (selection: $selectedItem) {
Text("Home")
.tabItem { Image(systemName: "house") }
.tag(1)
.onAppear { self.oldSelectedItem = self.selectedItem }
Text("Search")
.tabItem { Image(systemName: "magnifyingglass") }
.tag(2)
.onAppear { self.oldSelectedItem = self.selectedItem }
Text("Add")
.tabItem { Image(systemName: "plus.circle") }
.tag(3)
.onAppear {
self.shouldShowActionSheet.toggle()
self.selectedItem = self.oldSelectedItem
}
Text("Heart")
.tabItem { Image(systemName: "heart") }
.tag(4)
.onAppear { self.oldSelectedItem = self.selectedItem }
Text("Profile")
.tabItem { Image(systemName: "person.crop.circle") }
.tag(5)
.onAppear { self.oldSelectedItem = self.selectedItem }
}
.actionSheet(isPresented: $shouldShowActionSheet) { ActionSheet(title: Text("Title"), message: Text("Message"), buttons: [.default(Text("Option 1"), action: option1), .default(Text("Option 2"), action: option2) , .cancel()]) }
}
func option1() {
// do logic 1
}
func option2() {
// do logic 2
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
Previous answers did not help me so I'm pasting my complete solution.
import SwiftUI
import UIKit
enum Tab {
case map
case recorded
}
#main
struct MyApp: App {
#State private var selectedTab: Tab = .map
#Environment(\.scenePhase) private var phase
