Hello. I am building an app that shows my walk workouts and in the detail view I want to show the route I took while walking, similar to that of the Apple Fitness App. There is a problem though, I cannot seem to understand how to connect the @State property workoutLocations array that would be used to draw the route on the map with what I get from the query. The task does successfully fetches the data but then when I try to use it later in a do-catch block nothing happens. What am I missing here?
import SwiftUI
import MapKit
import HealthKit
struct DetailView: View {
@Environment(HealthKitManager.self) var healthKitManager
let workout: HKWorkout
@State private var workoutLocations: [CLLocation] = []
var body: some View {
ScrollView {
//...
}
.task {
guard let store = self.healthKitManager.healthStore else {
fatalError("healthStore is nil. App is in invalid state.")
}
let walkingObjectQuery = HKQuery.predicateForObjects(from: workout)
let routeQuery = HKAnchoredObjectQueryDescriptor(predicates: [.workoutRoute(walkingObjectQuery)], anchor: nil)
let queryResults = routeQuery.results(for: store)
let task = Task {
var workoutRouteLocations: [CLLocation] = []
for try await result in queryResults {
let routeSamples = result.addedSamples
for routeSample in routeSamples {
let routeQueryDescriptor = HKWorkoutRouteQueryDescriptor(routeSample)
let locations = routeQueryDescriptor.results(for: store)
for try await location in locations {
workoutRouteLocations.append(location)
print(workoutRouteLocations.count) // this prints out the number of locations in the sample.
}
}
}
return workoutRouteLocations
}
do {
print(try await task.value.count) // this prints nothing. Therefore if I try to update workoutLocations array from here it would do nothing as well
// workoutLocations = try await task.value therefore does nothing and the array just doesn't get populated with the results of the task
} catch {
print(error)
}
}
}
}

In macOS, I am encountering an issue where the system API fails to grant permission to open a file despite enabling the necessary Read/Write permissions within the SandBox. Could you please elucidate the reasons behind this behavior? Thanks!
func finderOpenFileSystem(at path: String) {
let fileURL = URL(fileURLWithPath: path)
guard FileManager.default.fileExists(atPath: path) else {
print("Error: File does not exist at path: \(path)")
return
}
let success = NSWorkspace.shared.open(fileURL)
if success {
print("File opened successfully: \(fileURL)")
} else {
print("Error: Failed to open file: \(fileURL)")
}
}
In visionOS, there are existing modifiers that can completely conceal the hands. However, I am interested in learning how to achieve the effect of only one hand disappearing while the other hand remains visible.

Hello, New to swift ui and xcode. I am building a mobil app that will need bluetooth capabilities. When I make my custom info.plist file and set "Generate info.plist file" to No, it states it cannot find my file. Then when I set that to "Yes" it gives me an error stating that there are multiple versions of the file. In my editor I cant seem to set a path to it either. Any help would be greatly appreciated.
this is the result when the the section is set to No
Cannot code sign because the target does not have an Info.plist file and one is not being generated automatically. Apply an Info.plist file to the target using the INFOPLIST_FILE build setting or generate one automatically by setting the GENERATE_INFOPLIST_FILE build setting to YES (recommended).
this is when its set to yes:
Multiple commands produce '/Users/thatcherdeyoework/Library/Developer/Xcode/DerivedData/SwiftUI-weather-etzagqgbgkjotzenbomwvkhjfhzt/Build/Products/Debug-iphoneos/SwiftUI-weather.app/Info.plist'
I get the following fatal error when the user clicks Save in AddProductionView.
Fatal error: Duplicate keys of type 'AnyHashable' were found in a Dictionary. This usually means either that the type violates Hashable's requirements, or that members of such a dictionary were mutated after insertion.
As far as I’m aware, SwiftData automatically makes its models conform to Hashable, so this shouldn’t be a problem.
I think it has something to do with the picker, but for the life of me I can’t see what.
This error occurs about 75% of the time when Save is clicked.
I'm using Xcode 16.2 and iPhone SE 2nd Gen. Any help would be greatly appreciated…

SwiftData delete isn't working, when I attempt to delete a model, my app crashes and I get the following error:
SwiftData/PersistentModel.swift:359: Fatal error: Cannot remove My_App.Model2 from relationship Relationship - name: model2, options: [], valueType: Model2, destination: Model2, inverseName: models3, inverseKeypath: Optional(\Model2.models3) on My_App.Model3 because an appropriate default value is not configured.
I get that it's saying I don't have a default value, but why do I need one? Isn't @Relationship .cascade automatically deleting the associated models?
And onto of that, why is the error occurring within the do block, shouldn't it be caught by the catch, and printed?
I have put together a sample project below.
import SwiftUI
import SwiftData
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
.modelContainer(for: Model3.self)
}

init(name: String) {

I want to visualize the data stored in a DataFrame using various charts (barmark, sectormark, linemark, etc.).
My questions are as follows:
Can a DataFrame be used directly within a chart? If so, could you provide a simple example?
If it cannot be used directly, what is the correct way to use it? Could you provide an example?
Thank you for your help.
Best regards.
When I run this code, and click on one of both 'currentZin' in the first screen that comes up with the view WordView, I see the content of the .preview value I used to initialize currentVerse (Verse= .preview) and not the values of the currentVerse that is in the Button action.
When I leave the WordView-sheet and click again the WordView shows the good result. I looks that on the first click the currentVerse = verse in the Button is not executed. If Ido not initialize it, it has a nil value. Can Anyone explain what happens and how to solve it.

Hi,
I'm working with a very simple app that tries to read a coordinates card and past the data into diferent fields. The card's layout is COLUMNS from 1-10, ROWs from A-J and a two digit number for each cell. In my app, I have field for each of those cells (A1, A2...). I want that OCR to read that card and paste the info but I just cant. I have two problems. The camera won't close. It remains open until I press the button SAVE (this is not good because a user could take 3, 4, 5... pictures of the same card with, maybe, different results, and then? Which is the good one?). Then, after I press save, I can see the OCR kinda works ( the console prints all the date read) but the info is not pasted at all.
Any idea? I know is hard to know what's wrong but I've tried chatgpt and all it does... just doesn't work

Hi,
I thought that drag drop reorder should be very easy with SwiftUI, but apparently I was wrong (unless I'm missing something). It seems to me that SwiftUI's drag-drop reorder is only easy for List, which supports .onMove modifier.
However, for UI like Grid, a horizontal ScrollView with items in a HStack, I don't see any easy approach to implement this. For example,
ScrollView(.horizontal) {
HStack {
ForEach(items) {
ItemView(item)
}
}
}
Does anyone know what's the best way to implement drag drop reorder for this horizontal scroll view?
I am creating a Generate note app but I don't see the text in the button when I applied the MeshGradient. I removed the Mesh Gradient and text is there. Need some help to find the issue. I am new to app Development and I am learning how to use it. Below is the code:
import SwiftUI
struct ContentView: View {
@State private var inputText: String = ""
@State private var isLoading: Bool = false
var body: some View {

#Preview {
ContentView()

In SwiftUI, the content and cursor are intermittently outside the bounds of the TextEditor.
struct ContentView: View {
@State private var text = ""
var body: some View {
VStack {
TextEditor(text: $text)
.frame(maxWidth: .infinity, maxHeight: .infinity)
.border(Color.gray, width: 1)
}
.padding()
}
}
I enter multiline text into TextEditor.
The content and cursor are intermittently outside the bounds of the TextEditor at the bottom.
Screen recording:
The problem also appears on my iPad.
I guess it may be related to the input method.
Is it possible to solve this problem?
If I update vision pro size then textfield and button are not update as per its new size.
Its working on some scren but not in some screen.
Please refer below screenshot for your reference,
[Overview]
After building the UI with SwiftUI, when the data is updated through an API, new data is added at the top of the ScrollView, and new UI blocks are added. However, the scroll position remains at the previous location, and it does not move to the top.
[Reproduction Steps]
Build the view using ScrollView and LazyVGrid.
In the LazyVGrid, set up blocks A/B/C/D/E to appear conditionally (using ForEach and Switch).
Initially, the array only contains C/D/E.
After the API call, add A/B to the array.
[Details]
This issue does not occur on all devices and has been occurring since iOS 18.1. The affected device list is as follows:
iPhone 14 Pro
iPhone 15 Pro
iPhone 16 Pro Max
If this issue occurred equally across all devices, the resolution would be quicker. However, please note that it only occurs on some devices. Below is a part of the code I wrote:

RefreshableScrollView(onRefresh: { done in
// pullToRefresh Action
......
},
progress: { _ in
...
},
detectOffSetY: { offsetY in
// Scroll Detect Action
...
}) {
switch tab.item {
case .home:
HomeView(store: homeStore)
.onAppear {
homeViewStore.send(.blurblur {
tabbarAction blurblur
})
}
[HomeView]
Section(
header: HomeNaviView(data: navidata,
naviShadowShowYn: Yn)
) {
ForEach(viewStore.state.menuList, id: \.self) { menu in
switch menu {
case .A:
A(data: data)
case .B:
B(data: data)
case .C:
C(data: data)
P.S. The structure is SwiftUI + TCA, and the TCA version is 1.12.0 or later.
I'm in the process of migrating to the Observation framework but it seems like it is not compatible with didSet. I cannot find information about if this is just not supported or a new approach needs to be implemented?
import Observation
@Observable class MySettings {
var windowSize: CGSize = .zero
var isInFullscreen = false
var scalingMode: ScalingMode = .scaled {
didSet {
...
}
}
...
}
This code triggers this error:
Instance member 'scalingMode' cannot be used on type 'MySettings'; did you mean to use a value of this type instead?
Anyone knows what needs to be done? Thanks!
A simple button in SwiftUI does not have an accurate tap area. It's supposed to react to the tap gesture only when the user is tapping inside the bounds. But it's not.
iOS 14.5
Xcode 12.5.1 (12E507)
I am working on a project that contains a QuickLook View and Some ARViews. I want to restrict the entire app to Portrait orientation, but I want to allow the ARView to have Portrait and Landscape orientation.
If I restrict the app to Portrait in the Deployment Info settings, we can still turn the device to landscape in the ARView, However, there is an issue with "some" spatial audio files within the digital experience. Some spatial audio items, are placed appropriately, and others are panned oddly left.
If we allow Landscape Left and Right in the Deployment Info settings, all spatial audio behaves appropriately. So, we need to "lock" every other view as Portrait and only allow Portrait and Landscape on the ARView.
I'm not smart enough to know how to do that, but I found this excellent package on GitHub. It works as expected. https://github.com/wvteijlingen/swiftui-interface-orientation
However! When we wrap SwiftUI with UIKit, it appears every single view that contains an ARView is initialized at launch even though it is not visible. So, when the app launches, it is running multiple ARViews at once.
It appears we need to have some kind of lazy loading, so this doesn't occur, but again, I am not knowledgable enough for this yet. I tried to wrap it all in a LazyVStack, I tried a LazyView struct, but I couldn't get it to build appropriately.
I feel like this might be a common thing, so maybe there's already a simple answer I'm not able to locate? Any ideas??
Some of our users keep reporting that occasionally some widgets (which initially were working perfectly) are now broken and show only skeletons.
Note that the app has multiple widgets, and this happens only to some of them (that is when some widgets get broken, some other widgets are still working normally).
While developing the app, I came across this symptom as well, and when I read the device console, I found the following errors in the console (which the system was repeatedly reporting to the console):
Unable to get connection interface: Error Domain=LNConnectionErrorDomain Code=1100 "Unable to locate com.example.app.MyAppntents for the com.apple.intents-service extension point" UserInfo={NSLocalizedDescription=Unable to locate com.example.app.MyAppIntents for the com.apple.intents-service extension point}
The affected widgets use the 'UserDefaults with groups' to read the data that is stored by the host app. And I think that sometimes the widget fails (or even crashes) while reading the data from the UserDefaults and it ends up showing the skeleton.
The only remedy I found was
Uninstall the app
Reboot the device
Install the app again.
After this, the widget starts to work again..
So, what can be the reason behind this? Is this an iOS bug or what and how to fight it?
Using a button that is placed in the bottom ornament to set focus on a text field will not display the keyboard properly while a button embedded in the view will behave as expected.
To demonstrate the issue, simply run the attached project on Vision Pro with visionOS 1.1 and tap the Toggle 2 button in the bottom ornament. You’ll see that the field does have focus but the keyboard is now visible.
Run the same test with Toggle 1 and the field will get focus and the keyboard will show as expected.
import SwiftUI
import RealityKit
import RealityKitContent
struct ContentView: View {
@State private var text = ""
@State private var showKeyboard = false
@FocusState private var focusedField: FocusField?
private enum FocusField: Hashable {
case username
case password
}
var body: some View {
VStack {
TextField("Test", text: $text)
.focused($focusedField, equals: .username)
Text("Entered Text: \(text)")
.padding()
Button("Toggle 1") { // This button will work and show the keyboard
if focusedField != nil {
focusedField = nil
} else {
focusedField = .username
}
}
Spacer()
}
.padding()
.toolbar {
ToolbarItem(placement: .bottomOrnament) {
Button("Toggle 2") { // This button will set focus properly but not show the keyboard
if focusedField != nil {
focusedField = nil
} else {
focusedField = .username
}
}
}
}
}
}
Is there a way to work around this?
