Scrollview alignment - swift

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)
}

SwiftUI How to align the bottom of two text with different font size?

I’m trying to align the bottom of two Text but the larger one looks like thismy widget looks like this. I don’t know why there’s still some space below this Text view.
This is my code:
var body: some View {
GeometryReader{geometry in
ZStack(alignment: .center){
Image("background")
.resizable()
VStack(){
HStack(alignment: .bottom){
Text("3")
.lineLimit(1)
.font(.bold(.system(size: 100))())
.minimumScaleFactor(0.1)
.foregroundColor(Color.white)
.frame(width: nil, height: geometry.size.height/3, alignment: .bottom)
.lineLimit(1)
.shadow(radius: 2)
Text("cups")
.foregroundColor(Color.white)
.font(.system(size: 12))
.shadow(radius: 2)
}
Text("Next cup on")
.foregroundColor(Color.white)
.font(.system(size: 10))
.shadow(radius: 2)
.opacity(0.5)
Text("10 : 00")
.foregroundColor(Color.white)
.font(.system(size: 12))
.shadow(radius: 1)
.opacity(0.5)
}
}
}
}
What I want is the number 3’s bottom aligned to “cups”’s bottom.
Thanks!
Instead of .bottom, you can use .lastTextBaseline as your HStack alignment:
HStack(alignment: .lastTextBaseline) {
Text("Hello").font(.system(size: 40))
Text("World").font(.system(size: 10))
}

Why do the elements inside my VStack inside a HStack still go vertical

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:

Adding 2 backgrounds within a Z and HStack?

The color.red is my widgets main background but I would like to add a black background to the top behind the text "Line1" and image "2". So basically a black bar that stretches across the top under the text and image.
var body: some View {
ZStack {
Color.red
VStack(alignment: .leading, spacing: 0) {
HStack {
Text("Line1")
.foregroundColor(.orange)
.bold()
.font(.system(size: 17.5))
.padding(.top)
Spacer()
Image("2")
.resizable()
.frame(width: 25, height: 25)
.padding(.top)
}
.padding(.horizontal)
.border(Color.green)
VStack(alignment: .leading) {
Image("2")
.resizable()
.frame(width: 67, height: 30)
Text("State")
.foregroundColor(Color.green)
.font(.system(size: 15))
Text("1")
.foregroundColor(Color.blue)
.font(.system(size: 10))
.opacity(0.5)
Spacer()
Spacer()
}
.padding(.horizontal)
.border(Color.blue)
}
}
}
You can add a .background modifier to your first HStack:
HStack {
//content here
}
.padding(.horizontal)
.border(Color.green)
.background(Color.black)
Keep in mind that order of modifiers is important, so if you put the background before the padding, the padding will not have that background color -- that's why I used it last.

The leading alignment doesn't apply to the text SwiftUI

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)
}
}
