Using Swiftui I'm creating a chat application. I'm trying to align the text so that it appears on the right side of the screen and then messages from the other user will appear on the left. I have tried using VStack and using leading and trailing alignment, I have also tried just aligning the text attribute. I have a text, and then two buttons. I would like the trash can button and pencil button to all evenly line up on the right side.
VStack (alignment: .trailing ) {
HStack {
Text(data.text)
.padding(.bottom, 4)
.padding(.top, 4)
.padding(.leading, 8)
.padding(.trailing, 8)
.foregroundColor(Color.white)
.background(Color(UIColor.systemBlue))
.cornerRadius(20)
Button(action: {
self.showingPopover = true
}) {
Image(systemName: "pencil")
}
Button(action: {
viewModel.deleteData(id: data.id)
}) {
Image(systemName: "trash")
}
}
}
It is enough to use frame alignment for text, depending to user it can be conditionally changed in place, like
Text(data.text)
.padding(.bottom, 4)
.padding(.top, 4)
.padding(.leading, 8)
.padding(.trailing, 8)
.foregroundColor(Color.white)
.background(Color(UIColor.systemBlue))
.cornerRadius(20)
.frame(maxWidth: .infinity, alignment: isMe ? .trailing : .leading) // << here !!
You just need to add a Spacer() in the beginning of the HStack:
VStack (alignment: .trailing ) {
HStack {
// This Spacer() will "push" the text to the right
Spacer()
Text(data.text)
.padding(.bottom, 4)
.padding(.top, 4)
.padding(.leading, 8)
.padding(.trailing, 8)
.foregroundColor(Color.white)
.background(Color(UIColor.systemBlue))
.cornerRadius(20)
Button(action: {
self.showingPopover = true
}) {
Image(systemName: "pencil")
}
Button(action: {
viewModel.deleteData(id: data.id)
}) {
Image(systemName: "trash")
}
}
}
Similarly, for the replies put a Spacer() at the end of the HStack, too push the text to the left.

So I have the following code:
private var googleButton: some View {
Button {
// Empty
} label: {
HStack(alignment: .firstTextBaseline) {
Image(systemName: "globe")
Text("Continue with Google")
.font(.headline)
.frame(height: 35)
}
.foregroundColor(.black)
.frame(maxWidth: .infinity)
}
.tint(.white)
.buttonStyle(.borderedProminent)
.controlSize(.regular)
}
Which produces this look:
How do I properly apply a border with the proper corner radius?
I have tried applying .border, etc.. to the button but it's all causing errors.
You can use Label if you want.
Label("Continue with Google", systemImage: "heart")
.padding()
.background {
Color.gray
}.foregroundColor(.white)
.clipShape(RoundedRectangle(cornerRadius: 10.0, style: .continuous))
I would go with something like:
Button {
print("example")
} label: {
HStack(alignment: .firstTextBaseline) {
Image(systemName: "globe")
Text("Continue with Google")
.font(.headline)
.frame(height: 35)
}
.foregroundColor(.black)
.frame(maxWidth: .infinity)
}
.background(.white)
.controlSize(.regular)
.cornerRadius(5) // Have your custom value here
So basically this is my code.
Text("Melbourne, Victoria")
.font(.largeTitle)
.fontWeight(.bold)
.foregroundColor(Color.white)
.padding(.bottom, 30)
Image(systemName: "moon.fill")
.foregroundColor(Color.white)
.font(.system(size: 60))
Text("Today")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
Text("34°C")
.font(.title3)
.fontWeight(.medium)
.foregroundColor(Color.white)
Spacer()
HStack {
Image(systemName: "sun.max.fill")
.foregroundColor(Color.yellow)
.font(.system(size: 40))
.padding(.bottom, 550)
Text("Mon 34°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
.padding(.bottom, 550)
}
}
.background(
Image("night")
.ignoresSafeArea()
)
I want to make more of the days in this weather app each with it's on SF Symbol and everything is inside this VStack. And the days and SF symbols are inside a HStack to keep them horizontal. But if I want to put more of those the next time I do it they go next to each other but the symbol goes on top look at this.
This is the image with only 1 of those days
And this one is when I put more than 1 but its next to each other when I want them vertically aligned.
This is the one if I put them in another VStack which makes the SF symbol go above the text
IS there any solution to this?
The problem is your .padding(.bottom, 550).
Image(systemName: "sun.max.fill")
.foregroundColor(Color.yellow)
.font(.system(size: 40))
.padding(.bottom, 550) /// here!
It's currently attached to your first Image. As a result, the HStack is stretched vertically and it appears as though the first Image is higher up than second one.
To fix, move both .padding(.bottom, 550)s to outside your HStack.
You have quite a lot of arbitrary values for padding. You should have your layout adapt to various devices, rather than hard-coding that .bottom spacing for example.
Working example:
struct ContentView: View {
var body: some View {
VStack(spacing: 40) {
Text("Melbourne, Victoria")
.font(.largeTitle)
.fontWeight(.bold)
.foregroundColor(Color.white)
VStack {
Image(systemName: "moon.fill")
.foregroundColor(Color.white)
.font(.system(size: 60))
Text("Today")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
Text("34°C")
.font(.title3)
.fontWeight(.medium)
.foregroundColor(Color.white)
}
VStack(spacing: 10) {
HStack {
Image(systemName: "sun.max.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Mon 34°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
}
HStack {
Image(systemName: "cloud.sun.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Tue 28°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
}
}
Spacer()
}
.frame(maxWidth: .infinity)
.background(
Color(red: 0.34, green: 0.36, blue: 0.71)//Image("night")
.ignoresSafeArea()
)
}
}
Result:
Although there is already an outer VStack, they are nested VStacks because they have different amounts of padding. Multiple views are grouped together, and then those are grouped together with larger paddings to separate them.
Bonus
SF Symbols colors
Use:
.renderingMode(.original)
Rather than:
.foregroundColor(Color.yellow)
To color the SF Symbols with the default colors, as shown in the above example.
Align days
You can align the days across each HStack with a custom alignment guide. Use the following:
extension HorizontalAlignment {
struct LeadingDay: AlignmentID {
static func defaultValue(in context: ViewDimensions) -> CGFloat {
context[.leading]
}
}
static let leadingDay = HorizontalAlignment(LeadingDay.self)
}
Making the other following changes:
VStack(alignment: .leadingDay, spacing: 10) { // <- HERE
HStack {
Image(systemName: "sun.max.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Mon 34°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
.alignmentGuide(.leadingDay) { d in // <- HERE
d[.leading]
}
}
HStack {
Image(systemName: "cloud.sun.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Tue 28°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
.alignmentGuide(.leadingDay) { d in // <- HERE
d[.leading]
}
}
}
Result:
I have problem in SwiftUI. I created ScollView and post into some Views. (News Articles). When i launch app - ScrollView and content inside appears in dioganal way, like animation. But i need to launch app and get static ScrollView with views inside it, without any movements.
Also the same problem occurred when i open sheet view with ScrollView and Text Blocks inside. It also appers first 0.3s like dioganaly way. But how can i achive static ? Thank you all )
Place i use sheet controller (Also this block in ScrollView)
ScrollView{
ArticlePreView(image: "one", category: "Category", heading: "Header", author: "some text").onTapGesture {
self.showingDetail.toggle()
}.sheet(isPresented: $showingDetail) {
Home()
}
}
Image to understand
Video of problem
And this is place of my sheet controller
ScrollView() {
VStack {
HStack {
Text("Soem long title")
.font(.title)
.fontWeight(.bold)
Spacer()
Button(action: {
}) {
HStack {
Image(systemName: "heart.fill")
.foregroundColor(Color.gray)
}
.padding()
}
.background(
Circle()
.fill(Color.neuBackground)
)
.shadow(color: .dropShadow, radius: 15, x: 10, y: 10)
.shadow(color: .dropLight, radius: 15, x: -10, y: -10)
}
.padding(.horizontal, 35)
.padding(.top, 25)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Spacer(minLength: 50)
}
}.frame(width: UIScreen.main.bounds.size.width)
Fixed using
.frame(width: UIScreen.main.bounds.size.width)
.fixedSize()
SwiftUI is not adaptive
I have the following
struct hScrollView: View {
#State private var meals = ["short", "long Text", "really long text"]
var body: some View {
VStack(alignment: .leading) {
ScrollView(.vertical, showsIndicators: false) {
VStack(spacing: 30) {
ForEach(0 ..< meals.count) { count in
VStack(alignment: .leading) {
HStack(alignment: .center) { // .center is by default, so also remove
Text("\(count + 1) ")
.foregroundColor(Color.black)
.multilineTextAlignment(.leading)
.padding(.horizontal, 15)
.padding(.vertical, 5)
.background(
Capsule()
.fill(Color.black)
.opacity(0.20)
)
Spacer()
Text("\(self.meals[count]) ")
.foregroundColor(Color.black)
.multilineTextAlignment(.leading)
Spacer()
Button(action: {
print("Button was tapped")
}) {
Image(systemName: "pencil")
.foregroundColor(Color.yellow)
.font(.system(size: 25, weight: .bold))
.shadow(radius: 1)
}
}
}
.padding(.horizontal)
}
}
.frame(width: UIScreen.main.bounds.width) // set a fixed width
}
.frame(height: 500)
.frame(maxWidth: 400)
.padding(.top, 190)
}
}
}
If you noticed, the text is centered, I want it that way, but all beginning with .leading alignment so they all start at the same start point. What can I fix there? I tried putting the leading alignment in all the stacks :/
Thanks
Your view would be like
(1)|-------|short|-------|✏️
(2)|-----|long text|-----|✏️
(3)|-|really long text|-|✏️
so you should remove the Spacer() between the first Text and second instead of set text alignment.
HStack(alignment: .center) { // .center is by default, so also remove
Text("\(count + 1) ")
.foregroundColor(Color.black)
.multilineTextAlignment(.leading)
.padding(.horizontal, 15)
.padding(.vertical, 5)
.background(
Capsule()
.fill(Color.black)
.opacity(0.20)
)
// Spacer()
Text("\(self.meals[count]) ")
.foregroundColor(Color.black)
.multilineTextAlignment(.leading)
Spacer()
Button(action: {
print("Button was tapped")
}) {
Image(systemName: "pencil")
.foregroundColor(Color.yellow)
.font(.system(size: 25, weight: .bold))
.shadow(radius: 1)
}
}
I have the following:
VStack(alignment: .leading) {
ScrollView(.vertical, showsIndicators: false) {
VStack(alignment: .leading, spacing: 30) {
ForEach(0 ..< meals.count) { count in
HStack(alignment: .center,spacing: 120){
VStack{
Text("\(count + 1) ")
.foregroundColor(Color.black)
.padding(.horizontal, 8)
.padding(.vertical, 5)
.background(
Capsule()
.fill(Color.black)
.opacity(0.20)
)
}
VStack{
Text("\(self.meals[count]) ")
.foregroundColor(Color.black)
}
VStack{
Image(systemName: "pencil")
.foregroundColor(Color.black)
.font(.system(size: 20))
.background(Color.yellow)
}
}
}
}
.frame(width: UIScreen.main.bounds.width) // set a fixed width
// .background(Color.green)
}
.frame(height: 185)
.frame(maxWidth: 400)
.padding(.top, -200)
}
How can I make the pencil icon stay to the right? I tried putting alignment: .trailing on it but doesn't work.
I saw an example with geometry but then the scroll view gets weird, I need it with this. Also how can I make sure the width between the items stay the same across devices?
Instead of hardcoding spacing use Spacer() which like spring push subviews aside.
Note: You don't need VStack for only one subview, so it can be removed for simplicity.
Here is resulting row:
HStack { // .center is by default, so also remove
Text("\(count + 1) ")
.foregroundColor(Color.black)
.padding(.horizontal, 8)
.padding(.vertical, 5)
.background(
Capsule()
.fill(Color.black)
.opacity(0.20)
)
Spacer() // << here !!
Text("\(self.meals[count]) ")
.foregroundColor(Color.black)
Spacer() // << here !!
Image(systemName: "pencil")
.foregroundColor(Color.black)
.font(.system(size: 20))
.background(Color.yellow)
}
