SwiftUI .cornerRadius on Image not showing up - swift

I am currently working on a SwiftUI Chat View project, and I am trying to round the corner of an image, which is loaded via a URL and converted from UIImage to Image. Any ideas why .cornerRadius(10) isn't working?
Image(uiImage: imageFromFirebase!)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: UIScreen.main.bounds.width / 1.5, alignment: isCurrentUser ? .trailing : .leading)
.clipped()
.cornerRadius(10)
Here is the full container – there is probably a lot of unnecessary stuff here but in case it helps:
struct ContentMessageView: View {
var contentMessage: String
var isCurrentUser: Bool
var type: String
var name: String
var color: Color
var image: UIImage?
#State private var imageFromFirebase: UIImage?
func imageLoadFromURL(){
HTTPRequest.fetchImage(self.contentMessage) { (image) in
if image != nil {
imageFromFirebase = image!
}
}
}
var body: some View {
VStack{
if type == "image" {
if !isCurrentUser {
HStack{
Text(name).font(.caption).foregroundColor(Color.black.opacity(0.2)).padding(.horizontal)
Spacer()
}
}
HStack{
if isCurrentUser {
Spacer()
}
if imageFromFirebase != nil {
ZStack{
Image(uiImage: imageFromFirebase!)
.resizable()
.scaledToFit()
.cornerRadius(10)
.frame(width: UIScreen.main.bounds.width / 1.5, alignment: isCurrentUser ? .trailing : .leading)
// .overlay(RoundedRectangle(cornerRadius: 10)
.background(Color.black)
// .stroke(isCurrentUser ? Color(UIColor(red: 240/255, green: 240/255, blue: 240/255, alpha: 1.0)) : color, lineWidth: 5))
}
.shadow(color: Color.black.opacity(0.05), radius: 10)
}
if !isCurrentUser {
Spacer()
}
}.padding(.horizontal, 10)
}
}.onAppear(){
self.imageLoadFromURL()
}
}
}

It is working fine, you did use wrong syntax and placement for code!
import SwiftUI
struct ContentView: View {
var body: some View {
if let unwrappedUIImage: UIImage = UIImage(named: "your image name here") {
Image(uiImage: unwrappedUIImage)
.resizable()
.scaledToFit()
.cornerRadius(30)
.frame(width: 300, height: 300, alignment: .center)
}
}
}

SwiftUI scaled background intercepting clicks

I'm encountering an issue with SwiftUI on macOS (12.x) where a scaled background is interfering with mouse clicks. The following is a minimal example:
struct ContentView: View {
var body: some View {
VStack {
Button("Test") {
print("Tested")
}
Image(systemName: "waveform.circle")
.resizable()
.frame(width: 200, height: 200)
.background(
Image(systemName: "waveform.circle")
.resizable()
.foregroundColor(.red)
.scaleEffect(2.0)
.blur(radius: 20)
.clipped()
)
}
.frame(width: 500, height: 500)
}
}
Note that pressing the "Test" button doesn't actually work -- no message to the console is printed.
I've found a workaround using NSHostingView, but it's pretty ugly -- I'd love to know if there's a pure-SwiftUI solution to 'clip' the background View so that not only is it's appearance cut off, but also it's ability to intercept clicks.
Here's a workaround (note that turning off the scale effect also solves the issue).
struct ContentViewWorkAround: View {
#State private var scaleEffectOn = true
#State private var workAround = false
#ViewBuilder private var imageBackground: some View {
switch workAround {
case false:
Image(systemName: "waveform.circle")
.resizable()
.foregroundColor(.red)
.scaleEffect(scaleEffectOn ? 2.0 : 1.0)
.blur(radius: 20)
.clipped()
.frame(width: 200, height: 200) // ineffective at preventing clicks
case true:
NSHostingViewRepresented {
Image(systemName: "waveform.circle")
.resizable()
.foregroundColor(.green)
.scaleEffect(2.0)
.blur(radius: 20)
.clipped()
.frame(width: 200, height: 200)
}
}
}
var body: some View {
VStack {
Button("Test") {
print("Tested")
}
Image(systemName: "waveform.circle")
.resizable()
.frame(width: 200, height: 200)
.background(
imageBackground
)
Toggle("Scale effect", isOn: $scaleEffectOn)
Toggle("Workaround", isOn: $workAround)
}
.frame(width: 500, height: 500)
}
}
struct NSHostingViewRepresented<V>: NSViewRepresentable where V: View {
var content: () -> V
func makeNSView(context: Context) -> NSHostingView<V> {
NSHostingView(rootView: content())
}
func updateNSView(_ nsView: NSHostingView<V>, context: Context) { }
}
Have you tried?
.allowsHitTesting(false)
Deactivates the clicks and allows whatever look you want.
struct ContentView: View {
var body: some View {
VStack {
Button("Test") {
print("Tested")
}
Image(systemName: "waveform.circle")
.resizable()
.frame(width: 200, height: 200)
.background(
Image(systemName: "waveform.circle")
.resizable()
.foregroundColor(.red)
.scaleEffect(2.0)
.blur(radius: 20)
.clipped()
.allowsHitTesting(false)
)
}
.frame(width: 500, height: 500)
}
}

I'd like to use the navigation link.Newbie Wang is in the process of hair loss

I want to use Navigationlink. I've been a novice for 2 weeks since I started.I am currently learning SwiftUi.
I created "OnboredView" after watching YouTube, but I don't know how to connect "OnboredView" to "CountentView".
NavigationView(){
NavigationLink(destination: OnboardView())
I learned how to make it like this through YouTube, but I don't know what to do now. I put it here and there, but the red errors bother me.
Tell me how to connect "NavigationLink" by pressing the button on "CountentView".
I'd like to click "Chevron.Light" to move on to "OnboredView."And if possible, please let me know how I can get rid of the "onboard screen" on the second run?
I am not good at English.I'm sorry. I'm experiencing hair loss again.

NavigationLink won't transition to new View upon selecting custom Button

When I embed my Button inside a NavigationLink and I set the destination to a Text View, the view doesn't transition upon clicking the button, although it sometimes does transition if I just randomly click around the button. What am I doing wrong?
Here is what I'm working with...
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView{
VStack{
Spacer()
VStack(spacing: 50){
NavigationLink(destination: Text("Testing")){
awButton(content: "Request Support", backColor: Color(#colorLiteral(red: 0.1764705926, green: 0.01176470611, blue: 0.5607843399, alpha: 1)))
}
}
Spacer()
}
.navigationBarTitle(Text("AccessWeb"))
.navigationBarItems(trailing: HStack{
Image(systemName: "bell")
.font(.system(size: 30))
Image(systemName:"person.circle")
.font(.system(size: 30))
Text("Tester")
.font(.system(size: 20))
})
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
struct awButton: View {
var content : String
var backColor : Color
var body: some View {
Button(action: {}, label: {
VStack {
HStack {
Image(uiImage: #imageLiteral(resourceName: "awText"))
.resizable()
.frame(width: 30, height: 20)
.padding(.leading)
Spacer()
}
.padding(.top)
HStack {
Text("\(content)")
.font(.title)
.fontWeight(.semibold)
.offset(y: 10.0)
}
Spacer()
}
})
.foregroundColor(Color(#colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)))
.frame(width: 300, height: 150, alignment: .center)
.background(backColor)
.clipShape(RoundedRectangle(cornerRadius: 20, style: .continuous))
}
}
The NavigationLink wraps everything in a button already (or at least something that receives click/tap events), so by also including a Button in your custom view, you're preventing those tap events from getting to the original NavigationLink.
But, since your action is empty, you can just take out your Button wrapper:
struct awButton: View {
var content : String
var backColor : Color
var body: some View {
VStack {
HStack {
Image(systemName: "pencil")
.resizable()
.frame(width: 30, height: 20)
.padding(.leading)
Spacer()
}
.padding(.top)
HStack {
Text("\(content)")
.font(.title)
.fontWeight(.semibold)
.offset(y: 10.0)
}
Spacer()
}
.foregroundColor(Color(#colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)))
.frame(width: 300, height: 150, alignment: .center)
.background(backColor)
.clipShape(RoundedRectangle(cornerRadius: 20, style: .continuous))
}
}

How to present accurate star rating using SwiftUI?

I need to present accurate star rating like 3.1, 4.8 using SwiftUI.
The desired result should be like this:
Your general approach is good, but I believe it can be made much simpler.
The below code adapts to whatever size it is placed in (so if you want a specific size, put it in a frame).
Note that the internal ZStack isn't required in iOS 14, but GeometryReader still doesn't document its layout behavior (except in an Xcode 12 release note), so this makes it explicit.
struct StarsView: View {
var rating: CGFloat
var maxRating: Int
var body: some View {
let stars = HStack(spacing: 0) {
ForEach(0..<maxRating, id: \.self) { _ in
Image(systemName: "star.fill")
.resizable()
.aspectRatio(contentMode: .fit)
}
}
stars.overlay(
GeometryReader { g in
let width = rating / CGFloat(maxRating) * g.size.width
ZStack(alignment: .leading) {
Rectangle()
.frame(width: width)
.foregroundColor(.yellow)
}
}
.mask(stars)
)
.foregroundColor(.gray)
}
}
This draws all the stars in gray, and then creates a yellow rectangle of the correct width, masks it to the stars, and draws that on top as an overlay. Overlays are automatically the same size as the view they're attached to, so you don't need all the frames to make the sizes match they way you do with a ZStack.
After spending some time I did found a solution.
struct StarsView: View {
let rating: CGFloat
let maxRating: CGFloat
private let size: CGFloat = 12
var body: some View {
let text = HStack(spacing: 0) {
Image(systemName: "star.fill")
.resizable()
.frame(width: size, height: size, alignment: .center)
Image(systemName: "star.fill")
.resizable()
.frame(width: size, height: size, alignment: .center)
Image(systemName: "star.fill")
.resizable()
.frame(width: size, height: size, alignment: .center)
Image(systemName: "star.fill")
.resizable()
.frame(width: size, height: size, alignment: .center)
Image(systemName: "star.fill")
.resizable()
.frame(width: size, height: size, alignment: .center)
}
ZStack {
text
HStack(content: {
GeometryReader(content: { geometry in
HStack(spacing: 0, content: {
let width1 = self.valueForWidth(geometry.size.width, value: rating)
let width2 = self.valueForWidth(geometry.size.width, value: (maxRating - rating))
Rectangle()
.frame(width: width1, height: geometry.size.height, alignment: .center)
.foregroundColor(.yellow)
Rectangle()
.frame(width: width2, height: geometry.size.height, alignment: .center)
.foregroundColor(.gray)
})
})
.frame(width: size * maxRating, height: size, alignment: .trailing)
})
.mask(
text
)
}
.frame(width: size * maxRating, height: size, alignment: .leading)
}
func valueForWidth(_ width: CGFloat, value: CGFloat) -> CGFloat {
value * width / maxRating
}
}
Usage:
StarsView(rating: 2.4, maxRating: 5)
Another simple solution that enables star fill level through clipping. You can use it with following API:
/// Pass in rating as a Binding or provide a constant
StarRating(rating: .constant(1.6), maxRating: 5)
.font(.title2) // Provide font for sizing
Which looks like:
Implementation:
struct StarRating: View {
struct ClipShape: Shape {
let width: Double
func path(in rect: CGRect) -> Path {
Path(CGRect(x: rect.minX, y: rect.minY, width: width, height: rect.height))
}
}
#Binding var rating: Double
let maxRating: Int
init(rating: Binding<Double>, maxRating: Int) {
self.maxRating = maxRating
self._rating = rating
}
var body: some View {
HStack(spacing: 0) {
ForEach(0..<maxRating, id: \.self) { _ in
Text(Image(systemName: "star"))
.foregroundColor(.blue)
.aspectRatio(contentMode: .fill)
}
}.overlay(
GeometryReader { reader in
HStack(spacing: 0) {
ForEach(0..<maxRating, id: \.self) { _ in
Image(systemName: "star.fill")
.foregroundColor(.blue)
.aspectRatio(contentMode: .fit)
}
}
.clipShape(
ClipShape(width: (reader.size.width / CGFloat(maxRating)) * CGFloat(rating))
)
}
)
}
}

Overlay text on Image SwiftUI and WidgetKit

I'm currently creating a widget for my new iOS 14 app and I encountered a weird problem when I'm trying to add and Overlay with Text on top of my Image. The overlay is correctly working on a blank SwiftUI project but it's not working on the Widget.
Below you can find the code that I'm using. KFImage is from KingFisherSwiftUI, but if you want to test it, you can just add a static Image from the Asset or from the System.
Thanks!
struct NewItems: View {
var body: some View {
KFImage(URL(string: "https://img.freepik.com/free-vector/triangular-dark-polygonal-background_23-2148261453.jpg?size=626&ext=jpg")! )
.resizable()
//.frame(width: 200, height: 200, alignment: .center)
.overlay(TextView(), alignment: .bottomTrailing)
.cornerRadius(20)
}
}
struct TextView: View {
var body: some View {
ZStack {
Text("Hello World Beautiful wallpaper")
.foregroundColor(.white)
.shadow(color: .black, radius: 1, x: 1.0, y: 1.0)
.padding(6)
.opacity(0.8)
}
.background(Color.black)
.cornerRadius(10)
.padding(3)
}
}
[EDIT]
Below the result of the code. Looks like the image is on top of the text, even though it supposed to be in overlay.
In the end after multiple tries I managed to find an alternative solution.
struct TextView: View {
let entry: HelloWorldEntry
var body: some View {
ZStack {
Text("SOME TEXT")
.foregroundColor(.white)
.shadow(color: .black, radius: 1, x: 1.0, y: 1.0)
.padding(6)
.opacity(0.8)
}
.background(Color.black)
.cornerRadius(10)
.padding(6)
}
}
struct NewTest: View {
let entry: HelloWorldEntry
var body: some View {
VStack {}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(
KFImage(URL(string: "https://example.com/image.png")!)
.resizable()
.scaledToFill()
)
.overlay(TextView(entry: entry), alignment: .bottomTrailing)
}
}
