Is anyone having problems using .searchable inside a TabView?
Before I implemented the TabView it was working just fine, and it is still showing on the preview.
This is the code now (does not show the search bar):
var body: some View {
TabView {
NavigationStack {
List(searchResults, children: \.items) { item in
NavigationLink(destination: CarView(carData: carData).onAppear() {
carData.selectedCar = item.pageId
Task {
await carData.fetchCarData()
}
}) {
Text("\(item.name)")
}
.padding(.vertical, 8)
.fontDesign(.monospaced)
}
.listStyle(.plain)
.searchable(text: $searchText, placement: .navigationBarDrawer(displayMode: .always))
}
.tabItem {
Label("Models", systemImage: "list.dash")
}
AIView(classifier: classifier)
.tabItem {
Label("AI", systemImage: "camera.metering.multispot")
}
InfoView()
.tabItem {
Label("Info", systemImage: "info.square")
}
}
.tint(.darkBackground)
.navigationBarBackButtonHidden(true)
}
So I tried multiple forms of implementing the search bar and none worked well, some of options really broke the tabview or the bar was always visible in any view with broken animations.
This is the code before where the search bar was working as intended (showing when the list is pulled).
var body: some View {
NavigationStack {
List(searchResults, children: \.items) { item in
NavigationLink(destination: CarView(carData: carData).onAppear() {
carData.selectedCar = item.pageId
Task {
await carData.fetchCarData()
}
}) {
Text("\(item.name)")
}
}
.navigationBarTitle("Models", displayMode: .inline)
.listStyle(.plain)
.searchable(text: $searchText, placement: .navigationBarDrawer(displayMode: .automatic))
}
}
This is the preview which shows the search bar.

So I built an app where you can add your personal expenses and it works fine but I added a loginView with faceID and when you login with that, it hides the second view's add and edit button, besides the search bar where you can filter the expenses
Here's the code that worked before i added the loginView
struct MainView: View {
#StateObject var PEviewModel = PEViewModel()
var body: some View {
// NavigationStack {
TabView {
PersonalExpensesView()
.environmentObject(PEviewModel)
.tabItem {
Label("Personal expenses list", systemImage: "dollarsign.circle")
}
// another view
.tabItem {
Label("Graph", systemImage: "chart.bar.fill")
}
}
}
//.navigationBarBackButtonHidden()
}
}
The MainView contains the two views you can navigate in. I added that navigationStack and the navigationBarBackButton() just to delete the back bar button so I could try if it worked (it didn't). PersonalExpensesView has the following (and it worked before the logInUpdate)
var body: some View {
NavigationStack {
VStack {
// all the listing of personal expenses and stuff
.navigationTitle("Personal Expenses")
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
EditButton()
}
ToolbarItem(placement: .navigationBarTrailing) {
Button {
showingSheet = true
} label: {
Label("Add Book", systemImage: "plus")
}
}
}
}
.searchable(text: $textFilter)
.sheet(isPresented: $showingSheet) {
NewPEView()
.environmentObject(PEviewModel)
}
}
}
}
And here's the code I added later (the logIn code) :
var body: some View {
NavigationStack {
VStack {
Button() {
authenticate()
} label: {
Label("Usar Face ID", systemImage: "faceid")
}
.customButton()
.navigationDestination(isPresented: $unlocked){// authenticate() sets unlocked true
MainView()
}
}
}
So the correct UI (without using login) is the following
correct
And with login: bugged
I tried using a NavigationStack as I showed in the MainView()
I'm a beginner at swiftui. I need to add an exit button to .navigationBarItems. How can I add this button in the parent NavigationView to show this button on all children's views?
// a simple example on my question
struct FirstView: View {
var body: some View {
NavigationView {
ZStack{
TabView{
SubExampleViewOne()
.tabItem {
Image(systemName: "house.fill")
Text("Home")
}
SubExampleViewTwo()
.tabItem {
Image(systemName: "bookmark.circle.fill")
Text("Bookmark")
}
}
}
//here I have added a toolbar and it is perfectly visible in tabitem
//this is what I am trying to achieve, the visibility of the button on all pages
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
ButtonExitView()
}
}
}
}
}
something strange - if I add NavigationLink in this way, Image and Text("Home") are visible twice
and the ToolbarItem is no longer on the new page
struct SubExampleViewOne: View {
var body: some View {
Text("This is hime page!")
.padding()
NavigationLink(destination: SubExampleViewThree()){
Text("Navigation link")
}
}
}
struct SubExampleViewTwo: View {
var body: some View {
Text("Hello, world!")
.padding()
}
}
struct SubExampleViewThree: View {
var body: some View {
Text("This is Navigation link")
.padding()
}
}
struct ButtonExitView: View {
var body: some View {
Button(action: {}, label: {Image(systemName: "arrowshape.turn.up.right.circle")})
}
}
after learning about TabView, I thought that there should be a similar solution for the top of the page
You have to add the button to each child view separately.
And you should use .toolbar and .toolBarItem because .navigationBarItems is deprecated.
I'm trying replicate the behavior of iOS Photos app.
Till now the thing I can't figure how could be done is the select mode, where when I press the button select how I can change the bottom bar?
Graphically, what I intend is, in this view:
When I pressed the button, the bottom bar changes to:
In the real project the views are embed inside a NavigationView
The code of the main view is similar to
struct ContentView: View {
var body: some View {
NavigationView{
TabView{
data()
.tabItem {
Text("Data")
}
data2()
.tabItem {
Text("Data")
}
}
}
}
I'm using Xcode 12 and swiftUI 2.0
First we need Conditional modifier like that https://stackoverflow.com/a/61253769/2715636
struct conditionalModifier: ViewModifier {
var isShowing: Bool
func body(content: Content) -> some View {
Group {
if self.isShowing {
content
.toolbar {
ToolbarItem(placement: .bottomBar, content: {
Button(action: {
}){
Image(systemName: "square.and.arrow.up")
}
})
}
.toolbar {
ToolbarItem(placement: .status, content: {
Text("Toolbar")
.fontWeight(.bold)
})
}
}
}
}}
I don't need else statement cause I only want to see Toolbar
else { content }
And here is my Tabbar inside ZStack. We're gonna overlay it with Text using Conditional modifier applied to Text
struct ContentView: View {
#State private var showToolbar: Bool = false
var body: some View {
Button(action: {
showToolbar.toggle()
}, label: {
Text(showToolbar ? "Show Tabbar" : "Show Toolbar")
}).padding()
ZStack {
TabView {
someView()
.tabItem {
Image(systemName: "placeholdertext.fill")
Text("Tab 1")
}
someView()
.tabItem {
Image(systemName: "placeholdertext.fill")
Text("Tab ")
}
someView()
.tabItem {
Image(systemName: "placeholdertext.fill")
Text("Tab 3")
}
}
Text("")
.modifier(conditionalModifier(isShowing: showToolbar))
}
}}
Final result
tabbar to toolbar
There's a new view modifier in iOS 16 that let you switch the tab bar and the bottom bar.
https://developer.apple.com/documentation/swiftui/view/toolbar(_:for:)
For example,
ContentView()
.toolbar(isSelecting ? .visible : .hidden, for: .bottomBar)
.toolbar(isSelecting ? .hidden : .visible, for: .tabBar)
I want to create a bottom bar which should be common for all my page. Here I am posting the image:
I know how to do it using storyboard. But how can I do it in SwiftUI?
This kind of view is called tab bar in iOS and in SwiftUI it is called TabView. It is declared like this:
var body: some View {
TabView {
Text("Favourites Screen")
.tabItem {
Image(systemName: "heart.fill")
Text("Favourites")
}
Text("Friends Screen")
.tabItem {
Image(systemName: "person.fill")
Text("Friends")
}
Text("Nearby Screen")
.tabItem {
Image(systemName: "mappin.circle.fill")
Text("Nearby")
}
}
}
Alternatively, you can use Label view for giving name & icon of the tab:
struct BottomTabBar: View {
var body: some View {
TabView{
Text("Profile Contents")
.tabItem{
Label("Profile",systemImage: "person.fill")
}
Text("Tv Contents")
.tabItem{
Label("Tv",systemImage: "tv.fill")
}
}
}
}
I'm trying to build a TabbedView with the following simple code:
TabbedView {
Text("Hello world")
.tabItemLabel(Text("Hello"))
Text("Foo bar")
.tabItemLabel(Text("Foo"))
}
When running, both tabs are visible and enabled but the second tab's ("Foo") content is blank.
Try adding tags:
TabbedView {
Text("Hello world")
.tabItem { Text("Hello") }
.tag(0)
Text("Foo bar")
.tabItem { Text("Foo") }
.tag(1)
}
I was able to fix this by adding a selection state variable and passing that in for the selection:
struct ContentView : View {
#State private var selection = 1
var body: some View {
TabbedView(selection: $selection) {
Text("Tab 1!").tabItemLabel(
Text("Tab 1")).tag(1)
Text("Tab 2!").tabItemLabel(Text("Tab 2")).tag(2)
}
}
}
Now, tapping "Tab 2" will show "Tab 2!" on the screen, as opposed to a blank screen.
This was using Xcode 11.0 beta 2 (11M337n), macOS Catalina 10.15 Beta (19A487l).
In the newest version you should use TabView:
TabView {
AnyView()
.tabItem {
Text("Label 1")
}
AnyView()
.tabItem {
Text("Label 2")
}
}
In Xcode GM, TabbedView was renamed to TabView. So here's the right way to create a tab bar in SwiftUI now:
TabView {
Text("Hello world")
.tabItem { Text("Hello") }
.tag(0)
Text("Foo bar")
.tabItem { Text("Foo") }
.tag(1)
}
Try this way, but you can't use an icon from SF Symbols, use the icons from //icons8.com or from another platform. or watch this tutorial https://www.youtube.com/watch?v=3PfCU5h5z94
struct ContentView : View {
var body : some View {
TabbedView {
Living_R()
.tabItemLabel(VStack {
Image("home")
Text("Home")
}).tag(0)
ContentView()
.tabItemLabel(VStack {
Image("search")
Text("Search")
}).tag(1)
Text("Info")
.tabItemLabel(VStack {
Image("page")
Text("Doc")
}).tag(2)
}
}
}
