SwiftUI bottom sheet like note app's format tab - swiftui

Currently, I have to implement bottom sheet. And I found the very example of my need.
Is this component system component of swift or swiftui?
OR do I need to implement on my own?
PLEASE LET ME KNOW IF U HAVE SOME INFOS! XD
At first I implement with ZStack, drag gesture but the animation is not what I expected.
I need Information about whether there is component like .sheet(isPresented: Bool, content: View) of the modal like above image.

As our friend said before, it is a sheet. Inside the sheet you can either define a new view or call any of your views. Then you have to use the modifier .presentationDetents which receive a Set of PresentationDetents to say where the view has to stop when appearing on the screen. This modifier must be apply to the content of the sheet and not directly to the sheet.
struct ContentView: View {
#State var isSheetShown = false
var body: some View {
VStack {
Button("Show view"){
isSheetShown = true
}
}.sheet(isPresented: $isSheetShown, content: {
StackOfButtons()
.presentationDetents([.medium])
})
.padding()
}
}
Finally, to create that stack type of buttons you can put them all in a HStack, give them individually some padding, set a little of spacing in the HStack and the round the corners of the stack. Something like this:
struct StackOfButtons: View {
var body: some View {
HStack(spacing: 2){
Button {
print("Hola que ase")
} label: {
Image(systemName: "list.bullet")
.padding()
.background(.thinMaterial)
.foregroundColor(.black)
}
Button {
print("Hola que ase")
} label: {
Image(systemName: "list.dash")
.padding()
.background(.thinMaterial)
.foregroundColor(.black)
}
Button {
print("Hola que ase")
} label: {
Image(systemName: "list.number")
.padding()
.background(.thinMaterial)
.foregroundColor(.black)
}
}.cornerRadius(10)
}
}

SwiftUI - Fullscreen nested TabViews without visual glitch

I'm trying to get nested TabViews working in SwiftUI to achieve an onboarding flow prior to the main tabbed app screen but am running in to a non-obvious visual glitch.
I'd like the onboarding portion to be full-screen, ignoring safe areas, but the nested, tabbed, main app screen to honour safe areas.
The code below shows the glitch off: it's full-screen for the first couple of screens, but then - only on initial display - the tabs are below the safe area. If I swipe back and forwards again the tabs do then honour the safe area.
I've tried various combinations of .edgesIgnoringSafeArea(), .frame(), .offset(), as well as trying to make use of the values that GeometryReader provides. Removing the one .edgesIgnoringSafeArea() that is there gives me the (expected) bars below and above my tabs. Due to the swipe transitions I need the tabs to be full-screen.
I've also tried using .overlays to achieve the desired appearance and while this does work it requires more complex state manipulation and just feels wrong.
Finally, I've played around with nesting NavigationViews and TabViews and, as reported elsewhere, that rarely ends well.
I'd be grateful if someone could explain why I'm seeing this glitch (i.e. the gap in my understanding of SwiftUI's rendering/lifecycle, and why the nested tab bar changes position the second time it appears), and if there's a canonical way of achieving what I want. TIA.
// A simple tab view that can self-advance to the next tab.
// Included to simplify the main ContentView
struct SimpleTab: View {
#Binding var tab: Int
let label: String
let backgroundColour: Color
let withNext: Bool
var body: some View {
VStack {
Spacer()
Text(label)
.frame(maxWidth: .infinity, alignment: .center)
if withNext {
Button {
withAnimation {
tab += 1
}
} label: {
Text("Next ->")
}
}
Spacer()
}
.background(backgroundColour
.opacity(0.5))
}
}
struct ContentView: View {
#State var tab = 0
#State var nestedTab = 0
var body: some View {
VStack {
TabView(selection: $tab) {
SimpleTab(tab: $tab, label: "Onboarding 1", backgroundColour: .red, withNext: true)
.tag(0)
SimpleTab(tab: $tab, label: "Onboarding 2", backgroundColour: .green, withNext: true)
.tag(1)
TabView(selection: $nestedTab) {
SimpleTab(tab: $nestedTab, label: "Nested 0", backgroundColour: .blue, withNext: false)
.tabItem {
Label("Nested 0", systemImage: "0.circle")
}
.tag(0)
SimpleTab(tab: $nestedTab, label: "Nested 1", backgroundColour: .blue, withNext: false)
.tabItem {
Label("Nested 1", systemImage: "1.circle")
}
.tag(1)
}
.tabViewStyle(DefaultTabViewStyle())
.tag(2)
}
.edgesIgnoringSafeArea(.all)
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
.transition(.slide)
}
}
}

SwiftUI Is there any built in view that kind of slides in from the side and takes up 3/4 of the screen?

This is probably a custom view but in the Reddit app there's a toolbar and the top left button(3 lines) opens this kind of view from the side that moves the current view to the right so you can only see about 25% of it and a new view that takes up about 75% of the screen slides in. Is there anything like this built into SwiftUI and if there isn't how would I go about implementing something like this?
This is my custom side bar behave similarly to what you just mentioned, you can try it. (Images and Code are below)
Before click:
After clicked:
struct ContentView: View {
#State var isClicked = false
var body: some View {
HStack {
Rectangle()
.fill(.orange)
.frame(width: isClicked ? UIScreen.main.bounds.width * 0.75 : 0)
VStack {
HStack {
Button {
withAnimation {
isClicked.toggle()
}
} label: {
Image(systemName: "menucard.fill")
.padding(.leading)
}
Spacer()
}
Spacer()
}
}
}
}

Button Text Out-Of-Sync with Tappable Area

I have a navigation view with tab views inside. The reason for this arrangement is to make the tab views disappear when within the navigation views.
I am trying to place a button at the top right corner of the screen (outside the safe area). If EntryView is called directly, the view correctly places the button ("Save") in the corner without use of offset() or position() view modifiers.
When the tab view is called before EntryView, the Save button appears an inch or so below where I would like it to appear. With offset() or position() I can move the button text back where I would like it to appear, but the tappable area doesn't move to the new location.
I have tried different arrangements of ZStack and VStack, but the arrangement below is the closest I have come to getting the button to work in the upper right corner.
Here is where I would like the button to appear: https://i.stack.imgur.com/AMdKQ.png
Is there any way to move the tappable area up to where the text is located?
Or is there some better way to draw the top part of the view?
This code can be dropped directly into Xcode for analysis.
struct ContentView: View {
#State private var selectedTab: Tabs = .home
var body: some View {
NavigationView {
TabView (selection: $selectedTab) {
EntryView()
.tabItem {
Label("Home", systemImage: "house.circle.fill")
}.tag(Tabs.home)
HistoryView()
.tabItem {
Label("History", systemImage: "clock.fill")
}.tag(Tabs.history)
}
}
}
}
struct EntryView: View {
var body: some View {
GeometryReader { g in
ZStack (alignment: .top) {
Color.blue
.frame(height: (g.safeAreaInsets.top) * 0.6, alignment: .top)
.ignoresSafeArea()
HStack {
Spacer()
Button(action: {
print("Save tapped!")
}) {
Text("Save")
.font(Font.title3.bold())
.foregroundColor(.red)
.offset(y: g.size.height * -0.14)
// .position(x: g.size.width * 0.90, y: g.size.height * -0.115)
}
}
.padding(.trailing, 10)
}
}
}
}
struct HistoryView: View {
var body: some View {
VStack (alignment: .leading) {
Text("History Tab")
.padding(.top)
}
}
}
enum Tabs: String {
case home
case history
}

Disable or ignore taps on TabView in swiftui

I have a pretty usual app with a TabView. However, when a particular process is happening in one of the content views, I would like to prevent the user from switching tabs until that process is complete.
If I use the disabled property on the TabView itself (using a #State binding to drive it), then the entire content view seems disabled - taps don't appear to be getting through to buttons on the main view.
Example:
struct FooView: View {
var body: some View {
TabView {
View1().tabItem(...)
View2().tabItem(...)
}
.disabled(someStateVal)
}
}
Obviously, I want the View1 to still allow the user to, you know, do things. When someStateVal is true, the entire View1 doesn't respond.
Is there a way to prevent changing tabs based on someStateVal?
Thanks!
I could not find a way to individually disable a tabItem, so here is
an example idea until someone comes up with more principled solution.
The trick is to cover the tab bar with a clear rectangle to capture the taps.
struct ContentView: View {
#State var isBusy = false
var body: some View {
ZStack {
TabView {
TestView(isBusy: $isBusy)
.tabItem {Image(systemName: "globe")}
Text("textview 2")
.tabItem {Image(systemName: "info.circle")}
Text("textview 3")
.tabItem {Image(systemName: "gearshape")}
}
VStack {
Spacer()
if isBusy {
Rectangle()
.fill(Color.white.opacity(0.001))
.frame(width: .infinity, height: 50)
}
}
}
}
}
struct TestView: View {
#Binding var isBusy: Bool
var body: some View {
VStack {
Text("TestView")
Button(action: {
isBusy.toggle()
}) {
Text("Busy \(String(isBusy))").frame(width: 170, height: 70)
}
}
}
}
I use another trick. Just hide the tab image.
struct FooView: View {
var body: some View {
TabView {
View1().tabItem{Image(systemName: someStateVal ? "": "globe")}
View2().tabItem{Image(systemName: someStateVal ? "": "gearshape")}
}
}
}

Customize navigationBar in Swift UI

I am new in swift ui. I want to put image button on the side of the NavigationBar title.
I want to be able to click the user image and navigate to another view. How?
You need to use navigationBarItems for putting image to navigation bar and you should add NavigationLink to that image. For center the title you need to set navigation bar title's displayMode to .inline or you can use new Toolbar api
struct ContentView: View {
var body: some View {
NavigationView {
Text("Welcome to Stack Overflow")
.navigationBarTitle("Header", displayMode: .inline)
.navigationBarItems(leading: NavigationLink(destination: Text("Destination")) {
Image(systemName: "person.crop.circle.fill")
.font(.title)
})
}
}
}

Another way using toolbar item.
I am adding TapGesture on image icon, and keeping it out of navigation link, as the image is not getting circular inside the NavigationLink in ToolbarItemGroup.
By leveraging isActive property of NavigationLink which monitors onTap state we can determine either we want to push our view or not.
import SwiftUI
struct WeatherView: View {
#State var onTap = false
var borderColor: Color = Color("Black")
var addProjectToolbarItem: some ToolbarContent {
ToolbarItemGroup(placement: .navigationBarLeading) {
NavigationLink(destination:Text("Welcome"), isActive: self.$onTap) {
EmptyView()
}
Image("yourImage")
.resizable()
.frame(width: 32, height: 32)
.clipShape(Circle())
.onTapGesture {
onTap.toggle()
}
}
}
var body: some View {
NavigationView {
VStack {
Text("First view")
}
.toolbar{
addProjectToolbarItem
}
.navigationTitle("Header")
.navigationBarTitleDisplayMode(.inline)
}
}
}
