how to make is that when i press the burger menu it doesn't move the other content around it
i am using a button with an if statement in a ZStack to create a menu like effect from the side
import SwiftUI
struct ContentView: View {
#State private var showMenu = false
var body: some View {
VStack {
HStack {
Image("logo")
.resizable()
.frame(width: 164, height: 34)
.padding(15)
Spacer()
ZStack {
if showMenu{
Text("About")
.foregroundColor(.white)
.frame(width: UIScreen.main.bounds.width/2)
}
Button {
showMenu.toggle()
}label: {
Image("menu")
.resizable()
.frame(width: 30, height: 30)
.padding(15)
}
}
.background(Color.black.opacity(showMenu ? 0.7 : 0))
.animation(.default)
.edgesIgnoringSafeArea(.all)
.onTapGesture {
showMenu = false
}
}
VStack {
Text("Hire The World's Top Calibers")
.font(.system(size: 47))
.fontWeight(.semibold)
Image("image")
.resizable()
.frame(width: 500, height: 400)
Spacer()
HStack {
Button {
//code
}label: {
Rectangle()
.fill(.black)
.frame(width: 150, height: 70)
.overlay(
Text("Hire a Caliber")
.foregroundColor(.white)
)
}
.padding()
Button {
//code
}label: {
Rectangle()
.fill(.white)
.border(Color.black, width: 2)
.frame(width: 150, height: 70)
.overlay(
Text("Join as a Caliber")
.foregroundColor(.black)
)
}
.padding()
}
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
.preferredColorScheme(.light)
}
}
it was originally in a HStack and i tried putting it in a ZStack but that didn't work
i tried looking for answers on chatGPT and this is the best that i got
I am complete beginner with SwiftUI and I can't wrap my head around how to connect these images with views that represents lines. Now I simply have 3 VStacks with image and text and put them into a HStack, but don't know how to connect these images with a line shown in red in the picture I attached. Note that there's some space between the line and the image. I need general direction and some hints, full working code not necessary.
Thank you.
How's this?
In SwiftUI, you use HStacks and VStacks to stack your Views. For the red line, a Rectangle should do. Here's the code:
struct ContentView: View {
var body: some View {
HStack { /// horizontal stack
VStack {
Image(systemName: "face.smiling")
.font(.system(size: 80))
.padding()
.border(Color.black, width: 5)
Text("Text TEXTEXT")
}
Rectangle()
.fill(Color.red)
.frame(height: 5)
VStack {
Image(systemName: "face.smiling")
.font(.system(size: 80))
.padding()
.border(Color.black, width: 5)
Text("Text TEXTEXT")
}
Rectangle()
.fill(Color.red)
.frame(height: 5)
VStack {
Image(systemName: "face.smiling")
.font(.system(size: 80))
.padding()
.border(Color.black, width: 5)
Text("Text TEXTEXT")
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
.previewLayout(.fixed(width: 800, height: 200))
}
}
Version 1.0.0
I decided to give my answer which is same like aheze answer with this difference that you can have CustomVerticalAlignment as well! As I see in your Image in question you want that also:
with CustomVerticalAlignment: In center!
without CustomVerticalAlignment: off center!
import SwiftUI
struct ContentView: View {
var body: some View {
HStack(alignment: .customVerticalAlignment) {
VStack {
Image(systemName: "star")
.resizable()
.scaledToFit()
.frame(width: 50, height: 50, alignment: .center)
.padding()
.border(Color.black, width: 5)
.alignmentGuide(.customVerticalAlignment) { d in d[VerticalAlignment.center] }
Text("Text")
}
Capsule()
.fill(Color.red)
.frame(height: 5)
.alignmentGuide(.customVerticalAlignment) { d in d[VerticalAlignment.center] }
VStack {
Image(systemName: "star")
.resizable()
.scaledToFit()
.frame(width: 50, height: 50, alignment: .center)
.padding()
.border(Color.black, width: 5)
.alignmentGuide(.customVerticalAlignment) { d in d[VerticalAlignment.center] }
Text("Text")
}
Capsule()
.fill(Color.red)
.frame(height: 5)
.alignmentGuide(.customVerticalAlignment) { d in d[VerticalAlignment.center] }
VStack {
Image(systemName: "star")
.resizable()
.scaledToFit()
.frame(width: 50, height: 50, alignment: .center)
.padding()
.border(Color.black, width: 5)
.alignmentGuide(.customVerticalAlignment) { d in d[VerticalAlignment.center] }
Text("Text")
}
}
.padding()
}
}
extension VerticalAlignment {
struct CustomVerticalAlignment: AlignmentID {
static func defaultValue(in d: ViewDimensions) -> CGFloat {
d[VerticalAlignment.center]
}
}
static let customVerticalAlignment = VerticalAlignment(CustomVerticalAlignment.self)
}
Update Version 2.0.0
About this version: I would say it does the same job of version 1.0.0 in less code and also Text and Line are not depending on VStack or eachother any moere!
import SwiftUI
struct ContentView: View {
var body: some View {
HStack {
image.overlay(text.offset(y: 40), alignment: .bottom)
capsule
image.overlay(text.offset(y: 40), alignment: .bottom)
capsule
image.overlay(text.offset(y: 40), alignment: .bottom)
}
.padding(50)
}
var image: some View {
return Image(systemName: "star.fill")
.resizable()
.scaledToFit()
.padding(10)
.shadow(radius: 10)
.frame(width: 50, height: 50, alignment: .center)
.foregroundColor(Color.red)
.background(Color.yellow)
.border(Color.black, width: 5)
}
var capsule: some View {
return Capsule()
.fill(Color.red)
.frame(height: 5)
}
var text: some View {
return Text("Hello World!")
.lineLimit(1)
.fixedSize()
}
}
You could define a Shape that represents your line.
I used the spacing parameter of HStack to do the spacing:
struct MyLine : Shape {
func path(in rect: CGRect) -> Path {
Path { path in
path.move(to: CGPoint(x: 0, y: rect.midY))
path.addLine(to: CGPoint(x: rect.maxX, y: rect.midY))
}
}
}
struct ContentView: View {
var body: some View {
HStack(spacing: 10) {
VStack {
Image(systemName: "pencil")
Text("Label")
}
MyLine().stroke(Color.red)
VStack {
Image(systemName: "pencil")
Text("Label 2")
}
MyLine().stroke(Color.red)
VStack {
Image(systemName: "pencil")
Text("Label 3")
}
}
}
}
You could add a lineWidth parameter to make the stroke thicker:
.stroke(Color.red, lineWidth: 4)
Also, if you didn't using spacing on the HStack, you could using a padding modifier on either the VStacks or the MyLines to get the spacing.
I'm developing a iOS app relies on SwiftUI.
I have a ZStack view and inside it, I call a another view along with a button.
ZStack(alignment: .bottomTrailing) {
ImageStepView(data: self.data[randomImageNum])
Button(action: { self.showFavorites = true }) {
HStack {
Image(systemName: "suit.heart.fill")
Text("FAVORITES")
}
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: 15)
.foregroundColor(.white)
.padding()
.background(Color.black.opacity(0.6))
.cornerRadius(5)
.padding(.horizontal, 20)
}
}
ImageStepView.swift
struct ImageStepView: View {
var data: ImageDataModel
var body: some View {
GeometryReader { geometry in
ScrollView(.vertical) {
VStack{
Image(data.image)
.resizable()
.border(Color.white, width: 5)
.overlay(
Rectangle().stroke(Color.white, lineWidth: 4))
.shadow(color: Color.gray, radius: 10, x: 10, y: 10)
.scaledToFit()
.frame(height: geometry.size.height-110)
} .padding()
VStack{
VStack(alignment: .leading) {
HStack{...}
HStack {...}
}
Spacer()
.frame(height: 50)
VStack(alignment: .leading){
VStack{
HStack {...}
HStack {...}
HStack {...}
}
}
}.padding()
}.background(Color("Color").ignoresSafeArea(.all))
.frame(width: geometry.size.width)
.frame(minHeight: geometry.size.height)
}
}
}
ImageStepView has a ScroolView, that's why Button not appears on the end of ScroolView, it appears on bottom of the screen.
What I want is to show The Button not on bottom of the screen but end of the ImageStepView.
You can make the ImageStepView accept a generic parameter - a view to be injected:
struct ImageStepView<Injected: View>: View {
var data: ImageDataModel
var injectedView: () -> Injected
var body: some View {
GeometryReader { geometry in
ScrollView(.vertical) {
// ScrollView contents
injectedView()
}
.background(Color("Color").ignoresSafeArea(.all))
.frame(width: geometry.size.width)
.frame(minHeight: geometry.size.height)
}
}
}
and pass the injected view to the ImageStepView:
ImageStepView(data: self.data[randomImageNum]) {
Button(action: { self.showFavorites = true }) { ... }
}
or
ImageStepView(data: self.data[randomImageNum]) { EmptyView() }
Everytime I am going back to the start screen it seems that it stacks itself. You can see what i mean in the screenshot i attached. I added some borders so you can see what i mean
The code of the Start screen:
struct StartScreen: View {
var body: some View {
NavigationView{
VStack() {
Image("Headline").resizable().scaledToFit()
Image("GreenMonster")
.resizable()
.scaledToFit()
.frame(alignment: .top)
NavigationLink(destination: Game(monster: monster)) {
Text("Spielen")
.frame(width: 200, height: 50, alignment: .center)
.font(.title)
.padding()
.background(Color.blue)
.cornerRadius(40)
.foregroundColor(.white)
.padding(10)
.overlay(
RoundedRectangle(cornerRadius: 40)
.stroke(Color.blue, lineWidth: 5)
)
}.isDetailLink(false)
/*
NavigationLink(destination: Settings()){
Image("Settingswheel").resizable().scaledToFit().frame(width: 50, height: 50).offset(x: 150)
}
*/
}
}.navigationBarBackButtonHidden(true).border(Color.green)
}
}
and the code to go back is:
struct DefeatedView: View {
#EnvironmentObject var helper: Helper
var body: some View {
NavigationView(){
VStack(){
Text("BESIEGT!").foregroundColor(.green).font(.title).bold()
Image(monster[0].imageURL).resizable().scaledToFit()
NavigationLink(destination: StartScreen()){
Text("Zum Start").frame(width: 120, height: 6, alignment: .center)
.padding()
.background(Color.blue)
.cornerRadius(40)
.foregroundColor(.white)
.padding(10)
.overlay(
RoundedRectangle(cornerRadius: 40)
.stroke(Color.blue, lineWidth: 5)
)
}
}
}.navigationBarBackButtonHidden(true)
}
}
Thanks for the help i am new into SwiftUI
Add this to your DefeatedView
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
And then instead of using a NavigationLink again, use a button and push your View manually back to your Start View
Button(action: {
//Push navigation view back
self.presentationMode.wrappedValue.dismiss()
})
{
Text("Zum Start").frame(width: 120, height: 6, alignment: .center)
.padding()
.background(Color.blue)
.cornerRadius(40)
.foregroundColor(.white)
.padding(10)
.overlay(
RoundedRectangle(cornerRadius: 40)
.stroke(Color.blue, lineWidth: 5)
)
}
Edit:
As you pushed your NavigationView twice, calling presentation mode only once will indeed push back to your Game View. Here is a possible solution with ObservableObject.
class ViewHelper : ObservableObject
{
#Published var finishedGame : Bool = false
}
struct StartScreen: View {
#EnvironmentObject var viewHelper : ViewHelper
var body: some View {
NavigationLink(destination: Game(), isActive: self.$viewHelper.finishedGame) {
Text("Spielen")
And then when the gameplay Is finished, change the finishedGame variable.
struct DefeatedView: View {
#EnvironmentObject var viewHelper : ViewHelper
var body: some View {
NavigationView(){
VStack(){
Text("BESIEGT!").foregroundColor(.green).font(.title).bold()
Button(action: {
self.viewHelper.finishedGame = false
})
{
Text("Zum Start").frame(width: 120, height: 6, alignment: .center)
.padding()
.background(Color.blue)
.cornerRadius(40)
.foregroundColor(.white)
.padding(10)
.overlay(
RoundedRectangle(cornerRadius: 40)
.stroke(Color.blue, lineWidth: 5)
)
}
}
}.navigationBarBackButtonHidden(true)
I found the solution to my Problem on this Site:
https://thinkdiff.net/ios/swiftui-how-to-pop-to-root-view/
Given this code:
import SwiftUI
struct ContentView: View {
var body: some View {
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.lineLimit(nil)
.font(.body)
Spacer()
}
.background(Color.red)
}
}
#if DEBUG
struct ContentView_Previews : PreviewProvider {
static var previews: some View {
ContentView()
}
}
#endif
It results in this interface:
How can I make the VStack fill the width of the screen even if the labels/text components don't need the full width?
A trick I've found is to insert an empty HStack in the structure like so:
VStack(alignment: .leading) {
HStack {
Spacer()
}
Text("Title")
.font(.title)
Text("Content")
.lineLimit(nil)
.font(.body)
Spacer()
}
Which yields the desired design:
Is there a better way?
Try using the .frame modifier with the following options:
.frame(
minWidth: 0,
maxWidth: .infinity,
minHeight: 0,
maxHeight: .infinity,
alignment: .topLeading
)
struct ContentView: View {
var body: some View {
VStack(alignment: .leading) {
Text("Hello World")
.font(.title)
Text("Another")
.font(.body)
Spacer()
}
.frame(
minWidth: 0,
maxWidth: .infinity,
minHeight: 0,
maxHeight: .infinity,
alignment: .topLeading
)
.background(Color.red)
}
}
This is described as being a flexible frame (see the documentation), which will stretch to fill the whole screen, and when it has extra space it will center its contents inside of it.
With Swift 5.2 and iOS 13.4, according to your needs, you can use one of the following examples to align your VStack with top leading constraints and a full size frame.
Note that the code snippets below all result in the same display, but do not guarantee the effective frame of the VStack nor the number of View elements that might appear while debugging the view hierarchy.
1. Using frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:) method
The simplest approach is to set the frame of your VStack with maximum width and height and also pass the required alignment in frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:):
struct ContentView: View {
var body: some View {
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.font(.body)
}
.frame(
maxWidth: .infinity,
maxHeight: .infinity,
alignment: .topLeading
)
.background(Color.red)
}
}
2. Using Spacers to force alignment
You can embed your VStack inside a full size HStack and use trailing and bottom Spacers to force your VStack top leading alignment:
struct ContentView: View {
var body: some View {
HStack {
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.font(.body)
Spacer() // VStack bottom spacer
}
Spacer() // HStack trailing spacer
}
.frame(
maxWidth: .infinity,
maxHeight: .infinity
)
.background(Color.red)
}
}
3. Using a ZStack and a full size background View
This example shows how to embed your VStack inside a ZStack that has a top leading alignment. Note how the Color view is used to set maximum width and height:
struct ContentView: View {
var body: some View {
ZStack(alignment: .topLeading) {
Color.red
.frame(maxWidth: .infinity, maxHeight: .infinity)
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.font(.body)
}
}
}
}
4. Using GeometryReader
GeometryReader has the following declaration:
A container view that defines its content as a function of its own size and coordinate space. [...] This view returns a flexible preferred size to its parent layout.
The code snippet below shows how to use GeometryReader to align your VStack with top leading constraints and a full size frame:
struct ContentView : View {
var body: some View {
GeometryReader { geometryProxy in
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.font(.body)
}
.frame(
width: geometryProxy.size.width,
height: geometryProxy.size.height,
alignment: .topLeading
)
}
.background(Color.red)
}
}
5. Using overlay(_:alignment:) method
If you want to align your VStack with top leading constraints on top of an existing full size View, you can use overlay(_:alignment:) method:
struct ContentView: View {
var body: some View {
Color.red
.frame(
maxWidth: .infinity,
maxHeight: .infinity
)
.overlay(
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.font(.body)
},
alignment: .topLeading
)
}
}
Display:
An alternative stacking arrangement which works and is perhaps a bit more intuitive is the following:
struct ContentView: View {
var body: some View {
HStack() {
VStack(alignment: .leading) {
Text("Hello World")
.font(.title)
Text("Another")
.font(.body)
Spacer()
}
Spacer()
}.background(Color.red)
}
}
The content can also easily be re-positioned by removing the Spacer()'s if necessary.
There is a better way!
To make the VStack fill the width of it's parent you can use a GeometryReader and set the frame. (.relativeWidth(1.0) should work but apparently doesn't right now)
struct ContentView : View {
var body: some View {
GeometryReader { geometry in
VStack {
Text("test")
}
.frame(width: geometry.size.width,
height: nil,
alignment: .topLeading)
}
}
}
To make the VStack the width of the actual screen you can use UIScreen.main.bounds.width when setting the frame instead of using a GeometryReader, but I imagine you likely wanted the width of the parent view.
Also, this way has the added benefit of not adding spacing in your VStack which might happen (if you have spacing) if you added an HStack with a Spacer() as it's content to the VStack.
UPDATE - THERE IS NOT A BETTER WAY!
After checking out the accepted answer, I realized that the accepted answer doesn't actually work! It appears to work at first glance, but if you update the VStack to have a green background you'll notice the VStack is still the same width.
struct ContentView : View {
var body: some View {
NavigationView {
VStack(alignment: .leading) {
Text("Hello World")
.font(.title)
Text("Another")
.font(.body)
Spacer()
}
.background(Color.green)
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .topLeading)
.background(Color.red)
}
}
}
This is because .frame(...) is actually adding another view to the view hierarchy and that view ends up filling the screen. However, the VStack still does not.
This issue also seems to be the same in my answer as well and can be checked using the same approach as above (putting different background colors before and after the .frame(...). The only way that appears to actually widen the VStack is to use spacers:
struct ContentView : View {
var body: some View {
VStack(alignment: .leading) {
HStack{
Text("Title")
.font(.title)
Spacer()
}
Text("Content")
.lineLimit(nil)
.font(.body)
Spacer()
}
.background(Color.green)
}
}
The simplest way I manage to solve the issue was is by using a ZStack + .edgesIgnoringSafeArea(.all)
struct TestView : View {
var body: some View {
ZStack() {
Color.yellow.edgesIgnoringSafeArea(.all)
VStack {
Text("Hello World")
}
}
}
}
Way Number 1 -> Using MaxWidth & MaxHeight
import SwiftUI
struct SomeView: View {
var body: some View {
VStack {
Text("Hello, World!")
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(.red)
}
}
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
Way Number 2 -> Using Main Screen Bounds
import SwiftUI
struct SomeView: View {
var body: some View {
VStack {
Text("Hello, World!")
}
.frame(maxWidth: UIScreen.main.bounds.width, maxHeight: UIScreen.main.bounds.height)
.background(.red)
}
}
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
Way Number 3 -> Using Geometry Reader
import SwiftUI
struct SomeView: View {
var body: some View {
GeometryReader { geometryReader in
VStack {
Text("Hello, World!")
}
.frame(maxWidth: geometryReader.size.width, maxHeight: geometryReader.size.height)
.background(.red)
}
}
}
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
Way Number 4 -> Using Spacers
import SwiftUI
struct SomeView: View {
var body: some View {
VStack {
Text("Hello, World!")
HStack{
Spacer()
}
Spacer()
}
.background(.red)
}
}
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
EDIT: answer updated with simple (better) approach using .frame
Just use frame modifiers!
struct Expand: View {
var body: some View {
VStack(alignment: .leading) {
Text("Title")
.font(.title)
Text("Content")
.lineLimit(nil)
.font(.body)
}
.frame(maxWidth:.infinity,maxHeight:.infinity,alignment:.topLeading)
.background(Color.red)
}
}
note - you don't even need the spacer in the VStack!
note2 - if you don't want the white at top & bottom, then in the background use:
Color.red.edgesIgnoringSafeArea(.all)
use this
.edgesIgnoringSafeArea(.all)
A good solution and without "contraptions" is the forgotten ZStack
ZStack(alignment: .top){
Color.red
VStack{
Text("Hello World").font(.title)
Text("Another").font(.body)
}
}
Result:
You can do it by using GeometryReader
GeometryReader
Code:
struct ContentView : View {
var body: some View {
GeometryReader { geometry in
VStack {
Text("Turtle Rock").frame(width: geometry.size.width, height: geometry.size.height, alignment: .topLeading).background(Color.red)
}
}
}
}
Your output like:
One more alternative is to place one of the subviews inside of an HStack and place a Spacer() after it:
struct ContentView : View {
var body: some View {
VStack(alignment: .leading) {
HStack {
Text("Title")
.font(.title)
.background(Color.yellow)
Spacer()
}
Text("Content")
.lineLimit(nil)
.font(.body)
.background(Color.blue)
Spacer()
}
.background(Color.red)
}
}
resulting in :
This is a useful bit of code:
extension View {
func expandable () -> some View {
ZStack {
Color.clear
self
}
}
}
Compare the results with and without the .expandable() modifier:
Text("hello")
.background(Color.blue)
-
Text("hello")
.expandable()
.background(Color.blue)
This is what worked for me (ScrollView (optional) so more content can be added if needed, plus centered content):
import SwiftUI
struct SomeView: View {
var body: some View {
GeometryReader { geometry in
ScrollView(Axis.Set.horizontal) {
HStack(alignment: .center) {
ForEach(0..<8) { _ in
Text("🥳")
}
}.frame(width: geometry.size.width, height: 50)
}
}
}
}
// MARK: - Preview
#if DEBUG
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
#endif
Result
I know this will not work for everyone, but I thought it interesting that just adding a Divider solves for this.
struct DividerTest: View {
var body: some View {
VStack(alignment: .leading) {
Text("Foo")
Text("Bar")
Divider()
}.background(Color.red)
}
}

🛑 All other solutions are just adding a frame around the content!
✅ but this solution changes the actual frame!
Simple and correct extension
You can use this modifier
.flexible(width: true, height: false)
Demo
💡Note how contents are aligned exactly as you assign in the original stack
The code behind this ( FlexibleViewModifier.swift )
extension View {
func flexible(width: Bool, height: Bool) -> some View {
self.modifier(MatchingParentModifier(width: width, height: height))
}
}
struct MatchingParentModifier: ViewModifier {
#State private var intrinsicSize: CGSize = UIScreen.main.bounds.size
private let intrinsicWidth: Bool
private let intrinsicHeight: Bool
init(width: Bool, height: Bool) {
intrinsicWidth = !width
intrinsicHeight = !height
}
func body(content: Content) -> some View {
GeometryReader { _ in
content.modifier(intrinsicSizeModifier(intrinsicSize: $intrinsicSize))
}
.frame(
maxWidth: intrinsicWidth ? intrinsicSize.width : nil,
maxHeight: intrinsicHeight ? intrinsicSize.height : nil
)
}
}
struct intrinsicSizeModifier: ViewModifier {
#Binding var intrinsicSize: CGSize
func body(content: Content) -> some View {
content.readIntrinsicContentSize(to: $intrinsicSize)
}
}
struct IntrinsicContentSizePreferenceKey: PreferenceKey {
static let defaultValue: CGSize = .zero
static func reduce(value: inout CGSize, nextValue: () -> CGSize) {
value = nextValue()
}
}
extension View {
func readIntrinsicContentSize(to size: Binding<CGSize>) -> some View {
background(
GeometryReader {
Color.clear.preference(
key: IntrinsicContentSizePreferenceKey.self,
value: $0.size
)
}
)
.onPreferenceChange(IntrinsicContentSizePreferenceKey.self) {
size.wrappedValue = $0
}
}
}
Here another way which would save time in your projects:
Much less code and reusable in compare to other answers which they are not reusable!
extension View {
var maxedOut: some View {
return Color.clear
.overlay(self, alignment: .center)
}
func maxedOut(color: Color = Color.clear, alignment: Alignment = Alignment.center) -> some View {
return color
.overlay(self, alignment: alignment)
}
}
use case:
struct ContentView: View {
var body: some View {
Text("Hello, World!")
.maxedOut
.background(Color.blue)
Text("Hello, World!")
.maxedOut(color: Color.red)
}
}
Just add Color.clear to the bottom of the VStack, simple as that :)
struct ContentView: View {
var body: some View {
VStack(alignment: .leading) {
Text("Title")
Color.clear
}
.background(Color.red)
}
}
