Format number inside image bubble - swift

I'm having some trouble understanding how to properly align items in top of each other:
So I have the following VStack:
VStack(spacing: 0) {
Text("\(placeC.places.count)")
Image("map-pin-full-cluster-1")
.renderingMode(.template)
.resizable()
.frame(width: 35, height: 35)
.foregroundColor(.brown)
} //: END VStack
Which produces the following output:
What is the best way to have the number inside the circle? Is there a recommended SwiftUI builder that you all use that I can explore?

Typically you would use an .overlay:
Image("map-pin-full-cluster-1")
.renderingMode(.template)
.resizable()
.frame(width: 35, height: 35)
.foregroundColor(.brown)
.overlay(alignment: .top) {
Text("\(placeC.places.count)")
}
or a ZStack:
ZStack(alignment: .top) { // other alignments: .center, .bottom, .leading, .trailing
Image("map-pin-full-cluster-1")
.renderingMode(.template)
.resizable()
.frame(width: 35, height: 35)
.foregroundColor(.brown)
Text("\(placeC.places.count)")
.padding(.top, 4) // adjust this to move the text up/down
}

Why does ScrollView randomly push my views content downwards?

Here is my code:
import SwiftUI
struct TrendingView : View {
#State var selectedTab: Tabs = .hot
#State private var searchText = ""
var body: some View {
NavigationView {
VStack {
HStack {
Text(" Trending")
.font(.largeTitle)
.frame(width: 175, height: 50, alignment: .leading)
.overlay(
RoundedRectangle(cornerRadius: 5)
.stroke(.black, lineWidth: 2)
)
.italic()
.fontWeight(.heavy)
.foregroundColor(Color(hue: 1.0, saturation: 0.977, brightness: 0.985))
.offset(x: -75, y: -25)
.padding(.bottom, -20)
NavigationLink(destination: testT()) {
Image(systemName: "magnifyingglass.circle.fill")
.resizable()
.scaledToFit()
.frame(width: 40, height: 40)
.foregroundColor(.black)
.padding(.bottom, -20)
}
.offset(x: 50, y: -25)
.padding(.leading, 5.0)
}
ScrollView {
VStack {
Text("Hot Items 🔥")
.bold()
.italic()
.offset(x: 5)
.frame(width: 120, height: 25, alignment: .leading)
.overlay(
RoundedRectangle(cornerRadius: 5)
.stroke(.black, lineWidth: 2)
)
.background(.yellow)
.offset(x: -130, y: 5)
ScrollView(.horizontal) {
HStack {
NavigationLink(destination: ImageTest()) {
Image("testpic1")
.resizable()
.frame(width: 200, height: 200)
}
NavigationLink(destination: ImageTest()) {
Image("testpic3")
.resizable()
.frame(width: 200, height: 200)
}
}.offset(y: 30)
}
}
}
There seems to be some error with scrollview above my vstack as it randomly causes all the content on this view to shift downwards when switching to and from other views.Ive tried removing the scrollview and the error disappears and also tried changing it around in other places but I still get the error Can anybody point me in the right direction? Thanks
Fixed, added to the bottom of my code and it seems like the issue is solved
.navigationBarTitle(Text(""), displayMode: .inline)
.navigationBarHidden(true)

SwiftUI Horizontal ScrollView onTapGesture is Off

I am experiencing some very odd behavior from a Horizontal ScrollView, it seems as if the clickable frame of the cells are offset. For example, if you click on left half of the first cell it will register the click for the first cell, but if you click the right half of the first cell it will register a click on the second cell. I'm not sure why this is happening.
I've included the code below, you can copy and paste this code into a playground to reproduce the issue. Any ideas here?
struct TestView: View {
var image: String
var body: some View {
ZStack {
Image(systemName: image)
.resizable()
.aspectRatio(contentMode: .fill)
.frame(width: 104, height: 168)
.cornerRadius(8)
.clipped()
VStack {
Spacer()
Text("Testing")
.foregroundColor(Color.white)
.frame(alignment: .leading)
.padding(EdgeInsets(top: 0, leading: 10, bottom: 0, trailing: 10))
.shadow(radius: 5)
Text("1:40")
.foregroundColor(Color.white)
.frame(alignment: .leading)
.padding(EdgeInsets(top: 3, leading: 10, bottom: 10, trailing: 10))
.shadow(radius: 5)
}
.frame(width: 104, height: 168)
}
}
}
struct TestViewCollection: View {
var collection = ["tv", "faxmachine", "printer"]
var body: some View {
ScrollView {
HStack {
ForEach(collection, id: \.self) { image in
TestView(image: image)
.onTapGesture {
print(image)
}
}
}
}
}
}
PlaygroundPage.current.setLiveView(TestViewCollection())
The issue is that your images are not the same aspect ratio as the frame you have put them in, so they are overflowing the frame. The solution is pretty simple. Instead of using .clipped() which just clips what you can see, use .contentShape() which will will provide an area that the .tapGesture() will use as its tappable area. Like this:
Image(systemName: image)
.resizable()
.aspectRatio(contentMode: .fill)
.frame(width: 104, height: 168)
.cornerRadius(8)
.contentShape(Rectangle())
the problem is:
Image(systemName: image)
.resizable()
.aspectRatio(contentMode: .fill)
.frame(width: 104, height: 168)
.cornerRadius(8)
.clipped()
Change that .aspectRatio(contentMode: .fill). -> into .fit
if you just move .clipped() like this:
Image(systemName: image)
.resizable()
.aspectRatio(contentMode: .fill)
.clipped()
.frame(width: 104, height: 168)
You are going to see:
That's why is happening.

In SwiftUI what is an easy way to align more than one view in ZStack

I have a view and I want to add two icons to it, at top right side and at bottom right side. I managed to do that:
I used two ZStacks:
ZStack(alignment: .bottomTrailing)
{
ZStack(alignment: .topTrailing)
{
Image(item.thumbnailImage)
.clipShape(Circle())
.overlay(Circle()
.stroke(Color.gray, lineWidth: 2))
if item.isFavorite
{
Image(systemName: "star.fill")
.foregroundColor(.yellow)
.offset(x: 7, y: -7)
}
}
if item.ordered
{
Image(systemName: "checkmark.square.fill")
.offset(x: 7, y: 7)
}
}
But I have a feeling that there should be a simpler way than nesting ZStacks inside. Besides looks like the small icons don't have their x-centers aligned. I can probably fix that by changing an offset but that would make the code even more clumsy.
Is there a simpler way?
Use only one Zstack and wrap the two icons in a VStack.
ZStack(alignment: .trailing) {
Circle()
.stroke(Color.gray, lineWidth: 2)
VStack {
Image(systemName: "star.fill")
Spacer()
Image(systemName: "checkmark.square.fill")
}
// Adjust the position of star and checkmark
.offset(x: -10)
}
.frame(width: 100, height: 100)
You can use the overlay modifier, like this:
import PlaygroundSupport
import SwiftUI
PlaygroundPage.current.setLiveView(
Circle()
.strokeBorder(Color.gray, lineWidth: 6)
.frame(width: 44, height: 44)
.overlay(
Image(systemName: "star.fill")
.foregroundColor(.yellow)
.offset(x: 7, y: -7),
alignment: .topTrailing)
.overlay(
Image(systemName: "checkmark.square.fill")
.offset(x: 7, y: 7),
alignment: .bottomTrailing)
.padding()
)
If your deployment target is iOS 15 or later (or an aligned version of macOS, tvOS, or watchOS), you can use the ViewBuilder version of overlay instead:
import PlaygroundSupport
import SwiftUI
PlaygroundPage.current.setLiveView(
Circle()
.strokeBorder(Color.gray, lineWidth: 6)
.frame(width: 44, height: 44)
.overlay(alignment: .topTrailing) {
Image(systemName: "star.fill")
.foregroundColor(.yellow)
.offset(x: 7, y: -7)
}
.overlay(alignment: .bottomTrailing) {
Image(systemName: "checkmark.square.fill")
.offset(x: 7, y: 7)
}
.padding()
)
We can use lorem's suggestion to align the symbol centers using a VStack. Then we can factor out the two offset modifiers into a padding on the VStack.
import PlaygroundSupport
import SwiftUI
PlaygroundPage.current.setLiveView(
Circle()
.strokeBorder(Color.gray, lineWidth: 6)
.frame(width: 44, height: 44)
.overlay(
VStack(spacing: 0) {
Image(systemName: "star.fill")
.foregroundColor(.yellow)
Spacer()
Image(systemName: "checkmark.square.fill")
}.padding([.top, .bottom, .trailing], -7),
alignment: .trailing)
.padding()
)

How to have 2x2 made of squares fit screen in SwiftUI

I'm trying to create a 2x2 grid through either VStacks/HStacks or LazyVGrid to have the squares on each row fit the screen. For example, the first and second squares each take up half the width of the screen and based on that length, that'll determine the height to make it a square. How would I go about doing that in the two ways that I've mentioned or is there a better way to do it? Here's what I have so far.
VStack {
HStack {
Rectangle()
.fill(Color.gray)
.frame(width: 100, height: 100)
Rectangle()
.fill(Color.blue)
.frame(width: 100, height: 100)
}
HStack {
Rectangle()
.fill(Color.red)
.frame(width: 100, height: 100)
Rectangle()
.fill(Color.green)
.frame(width: 100, height: 100)
}
}
It feels wrong to hardcode the width and height for the frame property here or is that the way to go about removing the gaps between the squares? Would this way of hardcoding values scale to other phone sizes?
LazyVGrid(columns: layout) {
Rectangle()
.fill(Color.gray)
.frame(width: 210, height: 210)
Rectangle()
.fill(Color.blue)
.frame(width: 210, height: 210)
Rectangle()
.fill(Color.red)
.frame(width: 210, height: 210)
Rectangle()
.fill(Color.green)
.frame(width: 210, height: 210)
}
EDIT: Here's what the new code looks like to get what I wanted.
VStack(spacing: 0) {
HStack(spacing: 0) {
Rectangle()
.fill(Color.gray)
Rectangle()
.fill(Color.blue)
}
HStack(spacing: 0) {
Rectangle()
.fill(Color.red)
Rectangle()
.fill(Color.green)
}
}
.aspectRatio(1.0, contentMode: .fit)
Now to get it working with LazyVGrid.
It feels wrong to hardcode the width and height for frame here or is that the way to go about removing the gaps between the squares?
To remove the gaps between the squares, just modify the HStack / VStack to include spacing:
HStack(alignment: .center, spacing: 0, content: {
Rectangle()
.fill(Color.gray)
.frame(width: 100, height: 100)
Rectangle()
.fill(Color.blue)
.frame(width: 100, height: 100)
})
You can use GeometryReader, as seen here.
Example usage:
struct MyView: View {
var body: some View {
GeometryReader { geo in
//You now have access to geo.size.width and geo.size.height
}
}
}
Just apply the aspectRatio (value 1 and fit the screen) modifier, there is no need to specify any frame.
VStack {
HStack {
Rectangle()
.fill(Color.gray)
Rectangle()
.fill(Color.blue)
}
HStack {
Rectangle()
.fill(Color.red)
Rectangle()
.fill(Color.green)
}
}
.aspectRatio(1.0, contentMode: .fit)

SwiftUI layers in HStack

When I drag the rectangle to the left, the symbol is under the rectangle but on the right the symbol is over the rectangle, when I drag it to the right. I know, that the hierarchy of the HStack decides the layer but if I would do the right symbol over the rectangle, then both of the symbols are on the right side. I'm new at SwiftUI
HStack(spacing: 0.0){
Image(systemName: "lessthan.square")
.resizable()
.frame(width: 20.0, height: 20.0)
.padding(.leading, 30.0)
ZStack(alignment: .center) {
Group {
Rectangle()
.cornerRadius(20.0)
.frame(width: 250, height: 150)
.foregroundColor(Color(.white))
.position(rectPosition)
.shadow(radius: 5)
VStack{
Text("i")
.font(.system(size: 30))
Text("l")
.font(.system(size: 25))
}.position(rectPosition)
}.gesture(DragGesture().onChanged({ value in
self.rectPosition = CGPoint(x: value.location.x, y: 130)
}))
}
Image(systemName: "greaterthan.square")
.resizable()
.frame(width: 20.0, height: 20.0)
.padding(.trailing, 30.0)```
zIndex should help you... add it to ZStack
HStack {
Image(...)
ZStack {
...
}.zIndex(1) // << here !!
Image(...)
}
