Hi there -- I'm cleaning up the accessibility in our app and making sure it adheres to Apple's suggested guidelines.
For accessibilityHint, apple lists a couple of suggestions in the doc here: https://developer.apple.com/documentation/objectivec/nsobject/1615093-accessibilityhint
Notably this one is one that I'm having to change a lot in our app:
Don’t include the action type in the hint. For example, don't create hints like “Tap to play the song” or “Tapping plays the song.”
However, we have some buttons that do different actions based on a double or triple tap in VoiceOver, so our hint looks something like: "Double tap to do X, Triple Tap to do Y"
This violates the accessibilityHint guidelines, but I feel like changing this would mean the customer loses out on valuable information. What does apple suggest we do in this case?
Thanks in advance!

I'm trying to get the same path you'd get by running getconf DARWIN_USER_CACHE_DIR in the terminal, but via
FileManager.default.urls(for: , in:) , but can't really find out how
is there a way to do that other than running the shell script via swift?

Hello developers !
I've created a List or a ForEach from a binding where there are TextFields or TextEditors inside.
When I go to fill in the text, the keyboard dismisses after one char is typed in !
My need is to be able to add textfields as much as required.
Please have a look to this code
import SwiftUI
struct ContentView: View {
@State private var messages = ["Hello 1","Hello 2","Hello 3"]
var body: some View {
VStack(alignment: .leading) {
List($messages, id: \.self) { $msg in
TextEditor(text: $msg)
}
ForEach($messages, id: \.self) { $msg in
VStack{
TextEditor(text: $msg)
}
.contextMenu{
Button(role: .destructive, action: {
messages = messages.filter {$0 != msg}
}, label:{
Text("Delete entry")
})
}
}
Button(action: {
messages.append("-")
}
, label: {
Text("Add a row")
})
}
.background(.black)
.padding()
}
}
#Preview {
ContentView()
}
I'm using iOS 17.4 and Xcode 15.3
Thanks !

Hello fellow developers,
We are trying to develop a chatbot application for ios devices using the powers of Oracle Digital Assistant.
Main Documentation :- https://docs.oracle.com/en/cloud/paas/digital-assistant/use-chatbot/oracle-ios.html
Implementation instructions :- https://blogs.oracle.com/digitalassistant/post/oracle-techexchange-using-the-oracle-ios-sdk-to-integrate-oracle-digital-assistant-in-mobile-applications
The point is when we are trying to run the app, we are facing tons of warnings as in below screenshot.
Here is the code for the ViewController.swift as below:
//
// ViewController.swift
// ODA_Configure
//
// Created by Macbook on 15/05/24.
//
//import UIKit
//
//class ViewController: UIViewController {
//
// override func viewDidLoad() {
// super.viewDidLoad()
// // Do any additional setup after loading the view.
// }
//
//
//}
// Import the SDK
import UIKit
import BotClientUISDK
public class ViewController: UIViewController {
// Declare a global BotsViewController variable in your app view controller class
public var chatViewController: BotsViewController?
public override func viewDidLoad() {
super.viewDidLoad()
// Obtain a shared instance of BotsViewController from BotsUIManager
chatViewController = BotsUIManager.shared().viewControllerInstance()
// Specify the color changes if any in a particular component. Make sure you set all the required colors in BotsProperties before adding the chat view to the view controller.
// Add the chatViewController to your navigationController
self.navigationController?.pushViewController(chatViewController!, animated: false)
// Obtain a shared instance of BotsManager
let botsManager = BotsManager.shared()
// If you require access to callback methods provided in AuthenticationProvider. Make sure your class conforms to BotsMessageServiceDelegate
// botsManager.authenticationTokenProvider = self
let baseUrl = "idcs-oda-81e5e7409d52405784089abe830a8820-da12.data.digitalassistant.oci.oraclecloud.com"
let channelID = "ff8a2d3f-7d65-4dab-a09a-d8f574ce5b7a"
// Initialize a BotsConfiguration object and set feature flags if required.
let botsConfiguration = BotsConfiguration(url: baseUrl , channelId: channelID)
BotsManager.shared().connect(botsConfiguration: botsConfiguration)
// Set the feature flag values if the desired values are different from the default values
botsConfiguration.showConnectionStatus = true
botsConfiguration.enableSpeechSynthesis = true
botsConfiguration.disablePastActions = "none"
// Initialize the configuration in botsViewController. Make sure you set all the feature flag values before passing the botsConfiguration to initConfiguration.
chatViewController?.initConfiguration(botsConfiguration: botsConfiguration)
// If you require access to callback methods provided in BotsMessageServiceDelegate. Make sure your class conforms to BotsMessageServiceDelegate
//botsManager.delegate = self
// If you require access to callback methods provided in BotsEventListener. Make sure your class conforms to BotsEventListener
//botsManager.botsEventListener = self
// Initialize and establish connection to the chat server
BotsManager.shared().initialize(botsConfiguration: botsConfiguration, completionHandler: { (connectionStatus, error) in
if error != nil {
print ("Error: \(String(describing: error?.localizedDescription))")
} else {
print ("Connection Status: \(connectionStatus)")
}
})
}
}
After executing this code, we are getting the message as build succeeded , and this is the emulator, which happens to be blank white all the time.
Possibly due the warning which I have posted above this seems to be the showstopper in the development. We are developing this for a prestigious client and would request an assistance as soon as possible.
P.S :- We are using Xcode 15 with Simulator of version 17.0.

We have an iOS app built using Capacitor. We are seeing a large increase in app crashes on iOS 17.4 (iPhone). Other OS versions seem to be showing significantly fewer crash numbers. We are unsure what is causing this, as our app did not go through any major releases. I have attached the crash log below. Thanks

Hello! I want to create an indoor mapping application in Swift, using the LiDAR scanner. I searched among frameworks and I found that ARKit, RealityKit and RoomPlan would be useful. Which is the proper way to create a 2D indoor mapping app? And which is the proper way to create a 3D indoor mapping app? Are there any modifications I have to make on my code in order to have both?

Hi, I have been receiving an email error message:
ITMS-90426: Invalid Swift Support - The SwiftSupport folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.
when submitting an app to the App Store Connect using xcode.
I have searched for many solutions online, but none of them have worked. Later, I manually created the SwiftSupport directory and copied the Swift dynamic library (dylib) that the app depends on to this directory, as well as copying them to the. app/Frameworks directory. After submitting, I received an email saying that these. dylib dynamic libraries are not in the. app/Frameworks directory. I opened the IPA file and checked the directory, and I really saw that they are located below. I don't know where the problem is, can you tell me the exact reason?

I've been encountering a strange crash that occurs randomly on my app's startup. The app compiles and (usually) runs just fine but every so often will close out immediately within a second or two of launching. I have found no methods to consistently reproduce this crash.

I would include the full crash report but for the URL needed for file attachments contains sensitive language somehow?? Any help resolving this issue would be greatly appreciated.

Hello,
I'm facing an issue with the volume slider in AVPlayer. Despite setting the volume property and mute property to false, the volume slider does not work as expected.
Initially, the volume is muted with the slider set to the minimum. If I change the volume, when I release the slider, it returns to the minimum and the mute icon remains active. However, if I set it to maximum, the setting remains and the icon changes. However, the video volume never changes and remains at the value set in the code.
Here is the code I am using:
var player: AVPlayer!
var playerController: AVPlayerViewController!
override func viewDidLoad() {
super.viewDidLoad()
player = AVPlayer(url: URL(fileURLWithPath: Bundle.main.path(forResource: "video", ofType: "mp4")!))
player.volume = 0.5
player.isMuted = false
playerController = AVPlayerViewController()
playerController.player = player
playerController.view.frame = self.view.frame
addChild(playerController)
view.addSubview(playerController.view)
playerController.view.frame = view.bounds
playerController.didMove(toParent: self)
player.play()
}
Can someone please help me resolve this issue? Any assistance would be greatly appreciated.
Thank you.

I get this error while migrating from ObservableObject to @Observable.
Call to main actor-isolated initializer 'init()' in a synchronous nonisolated context
My original code:
struct SomeView: View {
@StateObject private var viewModel = ViewModel()
}
After migration:
@MainActor @Observable class BaseViewModel {
}
@MainActor class ViewModel: BaseViewModel {
}
struct SomeView: View {
@State private var viewModel = ViewModel()
}
As discussed here. It seems like @StateObject is adding @MainActor compliance to my View under the hood because it's wrappedValue and projectedValue properties are marked as @MainActor, while on @State they are not.
@available(iOS 14.0, macOS 11.0, tvOS 14.0, watchOS 7.0, *)
@frozen @propertyWrapper public struct StateObject<ObjectType> : DynamicProperty where ObjectType : ObservableObject {
...
@MainActor public var wrappedValue: ObjectType { get }
....
@MainActor public var projectedValue: ObservedObject<ObjectType>.Wrapper { get }
}
One solution for this is to mark my View explicitly as @MainActor struct ViewModel: View but it have it side effects, for example code like:
Button(action: resendButtonAction) {
Text(resendButtonAttributedTitle())
}
Will result a warning
Converting function value of type '@MainActor () -> ()' to '() -> Void' loses global actor 'MainActor'
While could be easily solved by using instead
Button(action: { resendButtonAction() } ) {
Text(resendButtonAttributedTitle())
}
I still feel like marking the whole View explicitly as @MainActor is not a good practice.
Adding fake @StateObject property to my view also do the trick, but it's a hack (the same for @FetchRequest).
Can anyone think of a more robust solution for this?

Problem Statement:
Unable to import .h file from an ObjC SPM to a .h file in an ObjC file in a framework with mix of ObjC and Swift code
The issue is: in order to support access of ObjC file in Swift code in a framework we need to use umbrella header (in place of bridging header). Once the file is imported in Umbrella header and made public it will no longer allow import of .h file from package in its interface
Project Structure:
a. Package: ObjCPackage
ObjCPackage
|- Package.swift
|- ObjCPackage
MathsUtilities.h (class interface)
MathsUtilities.m (class implementation)
NiceLogs.h (protocol)
b. Project: ObjCSwiftFramework
ObjCSwiftFramework
|- ObjCSwiftFramework.h (umbrella header)
|- Calculation.h (objc class interface)
|- Calculation.m (objc class implementation)
|- SwiftCalci.swift (swift class)
Details:
#import <ObjCSwiftFramework/Calculation.h> added in ObjCSwiftFramework.h as Calculation has to be used in SwiftCalci
Calculation.h marked as public in target membership in Xcode so that it can be added in umbrella header ObjCSwiftFramework.h
#import "NiceLogs.h" in Calculation.h gives error
Here is a small sample which I created to demonstrate the problem:
ObjCSwiftFramework
Hi --
I am attempting to use C++ and Swift in a single project but I am struggling with finding the proper way to do this. Ideally I want to have both my C++ and Swift code in the same project and not use a framework to keep them separate.
As an example, how would I create an object of the following C++ class:
class Foo {
public:
Foo() {
// do stuff
}
}
From what I read, it should be as simple as this:
let foo = Foo()
But Xcode says it Cannot find 'Foo' in scope. How do I import Foo into my Swift code? Is there a project setting that needs to be changed to automatically make my C++ classes available? Or do I need to create a Clang module (as described in this page: https://www.swift.org/documentation/cxx-interop/#importing-c-into-swift) to expose the C++ code to Swift? If so, where in my Xcode project should that go?
I am using Xcode 15.2 on macOS 14.2.1. I have also set the C++ and Objective-C Interoperability setting for my project to C++/Objective-C++.
I am trying to launch openImmersiveSpace, but seem like there is an issue with the openImmersiveSpace Task.
Error: Static method 'buildExpression' requires that 'Task<OpenImmersiveSpaceAction.Result, Never>' conform to 'View'
Here is the code and the error shows up on the "Task" line.
import SwiftUI
import RealityKit
import RealityKitContent
struct TestView: View {
@Environment(\.openImmersiveSpace) var openImmersiveSpace
@Environment(\.dismissImmersiveSpace) var dismissImmersiveSpace
var body: some View {
VStack{
Text("Open Full Immersive & switch to NextViewArea")
NavigationLink {
Task {
await openImmersiveSpace(id: "ImmersiveSpace")
}
NextViewArea()
} label:{
Label(" Enter Full Immersive Space")
}
}
}
}
How can I move onto the next view area in the floating window while also launching full immersive space. Any help would be much appreciated.

I have encountered a strange behavior these past couple weeks while dealing with Bluetooth, mostly because my code hasn't changed in over 6 months (maybe it was not working before and now it's correct, who knows). Essentially, when i pair with a bluetooth device for the first time, the onchange has stopped firing. I can post more exact code of the view but I didn't think it was necessary but after you select the device you want to connect to (for the first time) you get asked by the OS to pair. After successful connection, we read information from the device (the Profiles). Once I get that information, i set dataGathered to true which triggers .onChange and I can navigate. However, with this initial connection/pairing the .onChange is never triggered, but i know i'm getting my dataGathered set to true because my print is being set. Subsequent connections do cause .onChange to be triggered with 0 profiles and with many profiles. This code hasn't changed in months so i'm not sure if there's SwiftUI bug that's sprung up or what, or if there's an inherint issue with what i was doing and it's only now being caught.
struct DeviceSearchView: View {
@StateObject var connectedManager: Manager = Manager()
@StateObject var bluetoothListener: Listener = BluetoothListener()
var body: some View {
body
.onChange(self.bluetoothListener.connectedDevice) { device in
device.getData()
}
.onChange(self.connectedManager.dataGathered) { dataGathered in
// determine navigation
}
}
}
Manager Object
final class Manager: ObservedObject, BTDelegate, Identifiable /*i've tried adding/switching with Equatable but no change*/ {
@Published var dataGathered: Bool = false
@Published var profileList: Profile = [Profile]()
@Published var index: Int = 0
func updatedProfile(list: NSArray, selectedIndex: Int) {
print("profiles are in fact here")
var newList = [Profile]()
for element in list {
if let profile = element as? B50Profile {
print("\(profile.name)")
if !newList.contains(profile){
newList.append(profile)
}
}
}
self.profileList = newList
self.index = selectedIndex
self.dataGathered = true
print("data gathered is \(self.dataGathered)"
}
}

Hello everyone
My goal is to create Apple's activity ring sparkle effect. So I found Paul Hudson's Vortex library. There is already a sparkle effect, but I don't know how to modify it to achieve my goal. Because I'm pretty new to SwiftUI animations. Does anyone have any idea how I could do this?

I'm developing an app with a chart in SwiftUI. I want the following block of code to run when the chart is clicked. On my personal iPhone, the app works flawlessly. But when I try it in the simulator it crashes and gives me about 5-10 of the following errors. When I remove the @Query macro from the code block, the application does not crash in the simulator, but I continue to get the errors I mentioned. If I do not run the following code block, I do not get the errors I mentioned.
struct SaleDetailView: View {
@Query(filter: #Predicate<Registration> {
!$0.activeRegistration
}) private var regs: [Registration]
var body: some View {
VStack {
DailySaleView()
}
.padding()
}
}
Thank you in advance for your answers. Do not hesitate to ask if you have any questions.
Thanks, MFS
