I use SwiftUI to display a .svg image. This is my code:
ZStack {
VStack {
HStack {
Spacer()
Image("logo_yf_head")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 70, height: 70)
.padding([.bottom, .horizontal], 16)
}
Spacer()
}
(...)
This is working in debug build and in a signed ad-hoc build.
But when uploaded and installed from testflight i have following problems on all devices:
the icon is shown as a purple square or is blurry. This changes at runtime. It even flickers sometimes.
My asset attributes look like this:

I have to fix a problem with Images on SwiftUI. I currently have to fill the images I receive in a certain vertical container, which are the cells of a LazyVGrid, but the problem is that the tappable area expands over the designated one.
I used the Accessibility Inspector, and I found out that the area in excess is due the Images. (screenshot attached)
The code I'm using is something similar to the following:
Image(uiImage: image.image)
.resizable()
.aspectRatio(contentMode: .fill)
.frame(
maxWidth: width,
maxHeight: height
)
.clipped()
I thought that by having the frames and the clipped method I could get rid of this problem, but that's not the case unless I'm using some squared images. Any idea of what could work to fix this problem? Thanks!
Just add .contentShape(Rectangle()) at the bottom:
Image(uiImage: image.image)
.resizable()
.aspectRatio(contentMode: .fill)
.frame(
maxWidth: width,
maxHeight: height
)
.clipped()
.contentShape(Rectangle()) // <- Here!
Wrap content in Geometry Reader and you need to know the aspect ratio like I set 720/460 below
GeometryReader { gr in
Image(uiImage: image.image)
.resizable()
.aspectRatio(720/460, contentMode: .fit)
}
.clipped()
.aspectRatio(720/460, contentMode: .fit)
I am trying to fit a square shaped image in rectangle shaped ImageView. With storyboard, I can easily do it with content mode .aspectFit but I am unable to figure out how to do it with SwiftUI.
I am currently doing something like this:
Image("BG")
.resizable()
.aspectRatio(contentMode: .fill)
.scaledToFill()
.clipped()
.frame(height: 200)
which gives below output, notice the blue border is my actual ImageView:
However, I am expecting something like this which I did in storyboard:
You need to clip it after set size, like
Image("BG")
.resizable()
.aspectRatio(contentMode: .fill)
.scaledToFill()
.frame(height: 200)
.clipped() // << here !!
I have the following code below:
ZStack {
VStack {
NavigationView {
VStack() {
Spacer()
image?
.resizable()
.clipShape(Circle())
.aspectRatio(contentMode: .fill)
.frame(width: 160, height: 160)
.overlay(Circle().stroke(Color.white, lineWidth: 4))
.overlay(
CameraButtonView(showActionSheet: $showActionSheet)
.offset(x: 50, y: 65)
)
.shadow(radius: 10)
Form {
....
}
}
}
.environment(\.horizontalSizeClass, .compact)
}
}
in essence it pretty simplistic were the above portion is an image with the camera button so that users can either select from camera roll or take a picture, which will be displayed by the image, and the rest is a form when the user will be able to fill in the form accrodingly.
What I have been trying to do is make the top part of the view (the image portion) scroll up or if possible scroll/sink into the navigation bar (almost like in the iphone contacts app), when the user starts to scroll the form portion of the view.
Currently the form portion scrolls under the image portion, which as you can imagine take a good portion of the view, so hiding that top image portion would make it easier to fill in the rest of the form.
Has anyone been able to do so in SwiftUI?
I've a list of video, the image of these video are loaded in async way. In the mosaic I can see the activity indicator if is still loading, after the image was loaded, I can see the image preview. I've added an icon with play button.
When I scroll the list, it is not fluid. I've tried to change all async process, but without success. After some time I've tried to delete the Circle() function and was exactly it to decreases the performance.
Even if I solved the issue by changing the icon, I'd like to know if also you have this problem with circle function. It sounds like SKShapeNode in sprite kit.
Bad performance:
ZStack {
Circle()
.fill(Color.white)
.frame(width: 55, height: 55)
.opacity(0.7)
Image(systemName: "play.fill")
.font(Font.system(size: 33))
.opacity(0.7)
.foregroundColor(.black)})
}
Good performance:
Image(systemName: "play.circle.fill")
.resizable()
.frame(width: 50, height: 50)
.opacity(0.7)
.foregroundColor(Color.white)
I need to have back button which looks like the one displayed on any App's page in Apple App Store, having banner image. See image below:
I have tried finding any possible system icon image name as guided here:
https://stackoverflow.com/a/58900114/1152014
But couldn't find any appropriate one. Please guide.
The system icon image name is chevron.left.circle.fill (the one with fill color) and chevron.left.circle (the one without fill color)
By default the fill color is black, which you can change using the foreground color option.
import SwiftUI
struct ContentView: View {
var body: some View {
List {
Image(systemName: "chevron.left.circle.fill")
.resizable()
.frame(width: 50, height: 50, alignment: .center)
.listRowBackground(Color.green)
Text("")
Image(systemName: "chevron.left.circle")
.resizable()
.frame(width: 50, height: 50, alignment: .center)
.listRowBackground(Color.green)
}
.foregroundColor(.white)
}
}
