I've encountered an issue where using @Observable in SwiftUI causes extra initializations and deinitializations when a reference type is included as a property inside a struct. Specifically, when I include a reference type (a simple class Empty {}) inside a struct (Test), DetailsViewModel is initialized and deinitialized twice instead of once. If I remove the reference type, the behavior is correct.
This issue does not occur when using @StateObject instead of @Observable. Additionally, I've submitted a feedback report: FB16631081.
Steps to Reproduce
Run the provided SwiftUI sample code (tested on iOS 18.2 & iOS 18.3 using Xcode 16.2).
Observe the console logs when navigating to DetailsView.
Comment out var empty = Empty() in the Test struct.
Run again and compare console logs.
Change @Observable in DetailsViewModel to @StateObject and observe that the issue no longer occurs.
Expected Behavior
The DetailsViewModel should initialize once and deinitialize once, regardless of whether Test contains a reference type.
Actual Behavior
With var empty = Empty() present, DetailsViewModel initializes and deinitializes twice. However, if the reference type is removed, or when using @StateObject, the behavior is correct (one initialization, one deinitialization).
Code Sample
import SwiftUI
enum Route {
case details
}
@MainActor
@Observable
final class NavigationManager {
var path = NavigationPath()
}
struct ContentView: View {
@State private var navigationManager = NavigationManager()
var body: some View {
NavigationStack(path: $navigationManager.path) {
HomeView()
.environment(navigationManager)
}
}
}
final class Empty { }
struct Test {
var empty = Empty() // Comment this out to make it work
}
struct HomeView: View {
private let test = Test()
@Environment(NavigationManager.self) private var navigationManager
var body: some View {
Form {
Button("Go To Details View") {
navigationManager.path.append(Route.details)
}
}
.navigationTitle("Home View")
.navigationDestination(for: Route.self) { route in
switch route {
case .details:
DetailsView()
.environment(navigationManager)
}
}
}
}
@MainActor
@Observable
final class DetailsViewModel {
var fullScreenItem: Item?
init() {
print("DetailsViewModel Init")
}
deinit {
print("DetailsViewModel Deinit")
}
}
struct Item: Identifiable {
let id = UUID()
let value: Int
}
struct DetailsView: View {
@State private var viewModel = DetailsViewModel()
@Environment(NavigationManager.self) private var navigationManager
var body: some View {
ZStack {
Color.green
Button("Show Full Screen Cover") {
viewModel.fullScreenItem = .init(value: 4)
}
}
.navigationTitle("Details View")
.fullScreenCover(item: $viewModel.fullScreenItem) { item in
NavigationStack {
FullScreenView(item: item)
.navigationTitle("Full Screen Item: \(item.value)")
.toolbar {
ToolbarItem(placement: .cancellationAction) {
Button("Cancel") {
withAnimation(completionCriteria: .logicallyComplete) {
viewModel.fullScreenItem = nil
} completion: {
var transaction = Transaction()
transaction.disablesAnimations = true
withTransaction(transaction) {
navigationManager.path.removeLast()
}
}
}
}
}
}
}
}
}
struct FullScreenView: View {
@Environment(\.dismiss) var dismiss
let item: Item
var body: some View {
ZStack {
Color.red
Text("Full Screen View \(item.value)")
.navigationTitle("Full Screen View")
}
}
}
Console Output
With var empty = Empty() in Test
DetailsViewModel Init
DetailsViewModel Init
DetailsViewModel Deinit
DetailsViewModel Deinit
Without var empty = Empty() in Test
DetailsViewModel Init
DetailsViewModel Deinit
Using @StateObject Instead of @Observable
DetailsViewModel Init
DetailsViewModel Deinit
Additional Notes
This issue occurs only when using @Observable. Switching to @StateObject prevents it. This behavior suggests a possible issue with how SwiftUI handles reference-type properties inside structs when using @Observable.
Using a struct-only approach (removing Empty class) avoids the issue, but that’s not always a practical solution.
Questions for Discussion
Is this expected behavior with @Observable?
Could this be an unintended side effect of SwiftUI’s state management?
Are there any recommended workarounds apart from switching to @StateObject?
Would love to hear if anyone else has run into this or if Apple has provided any guidance!

I would like to report a memory leak issue in watchOS 11.2 that occurs when using .navigationTitle() inside a sheet. This behavior is reproducible both on the simulator and on a real device, but not on iOS. While this does not register as a leak in Instruments, the deinit of the DetailsViewModel is never called, and multiple instances of the view model accumulate in the Memory Graph Debugger. Commenting out .navigationTitle("Sheet View") resolves the issue, and deinit prints as expected. Using @MainActor on the DetailsViewModel does not fix the issue. Nor does switching to @StateObject and using ObservableObject resolve the memory retention.
This issue seems related to other SwiftUI memory leaks that have been reported:

I’m getting a 0xdead10cc crash in a basic CoreData/CloudKit application. I only have one CoreData save call and its made when the app is in the foreground and it's minor so I don't think its being caused by that. My best guess is that it's related to background syncing of CloudKit. Does anyone know how to fix it? I've been advised that adding the following code around any saves will fix it, but it seems weird that this is the solution. I would expect the inner CoreData/CloudKit engine to handle this.
ProcessInfo().performActivity(reason: "Persisting to context") {
// Save to context here
}
Here is the crashing thread

I have integrated CloudKit into a CoreData application and am ready to deploy the schema to production but keep getting an "internal error" when trying to deploy to production or reset my CloudKit environment. I have attached images of what I am seeing including one of the console error. Is there any way to resolve this?
I'm displaying a GKGameCenterViewController after successfully authenticating and on iOS 18.0 and 18.1, I get a black screen. As a sanity check GKLocalPlayer.local.isAuthenticated is also returning true. The same code works just fine on iOS 17. Is there something that needs to be done on iOS 18 and above?
MPMusicPlayerControllers nowPlayingItem no longer seems to be able to change a song. The code use to work but seems to be broken on iOS 16, 17 and now the iOS 18 beta.
When newSong is triggered, the song restarts but it does not change songs. Instead I get the following error: Failed to set now playing item error=<MPMusicPlayerControllerErrorDomain.5 "Unable to play item <MPConcreteMediaItem: 0x9e9f0ef70> 206357861099970620" {}>.
The documentation seems to indicate I’m doing things correctly.
class MusicPlayer {
var songTwo: MPMediaItem?
let player = MPMusicPlayerController.applicationMusicPlayer
func start() async {
await MPMediaLibrary.requestAuthorization()
let myPlaylistsQuery = MPMediaQuery.playlists()
let playlists = myPlaylistsQuery.collections!.filter { $0.items.count > 2}
let playlist = playlists.first!
let songOne = playlist.items.first!
songTwo = playlist.items[1]
player.setQueue(with: playlist)
play(songOne)
}
func newSong() {
guard let songTwo else { return }
play(songTwo)
}
private func play(_ song: MPMediaItem) {
player.stop()
player.nowPlayingItem = song
player.prepareToPlay()
player.play()
}
}
When using .accessibilityElement(children: .contain) on a SwiftUI Button, the children do not show up in the accessibility inspector. Instead, the Button is the only element shown and its identifier is a combination of all the children. How can I make only the children identifiers show?
Button {
} label: {
VStack {
Image(systemName: "star")
.accessibilityIdentifier("logo_image")
Text("Subtitle")
.accessibilityIdentifier("subtitle_text")
}
}
.accessibilityElement(children: .contain)
If I remove the button and only use the VStack the elements appear individually. This is what I am trying to achieve while using the Button.
VStack {
Image(systemName: "star")
.accessibilityIdentifier("logo_image")
Text("Subtitle")
.accessibilityIdentifier("subtitle_text")
}
I have a simple UIKit application that has a UITextView in a UICollectionViewCell. The app is designed for iOS/iPadOS and works just fine on those platforms. However, when run on Mac (Designed for iPad) as soon as I start scrolling the collectionview, the cpu usage spikes to ~85% and stays there indefinitely. The only way to lower the cpu is to click outside of the application window, but once it comes to the foreground again, the cpu usage jumps right back up. I've tried running on Mac in Catalyst mode too, but the same problem occurs with slightly less cpu usage (~45%).
Additionally the debugger constantly spits out [API] cannot add handler to 3 from 3 - dropping while scrolling.
Does anyone have an explanation or solutions for this?

Is there anyway to hide the details view controller of a UISplitviewController in all circumstances? I have this requirement where the details VC needs to be hidden (or absent) at first and then slide in from the right when an initial selection is made. This needs to be the case even when a large iPad is in full screen mode.
I know I can simply create my own version of this using a view controller with two child view controllers embed and manipulating constraints, however then I lose the push and pop functionally that you automatically get when in a compact size class.
I have a UICollectionViewLayout grid with three columns. Each item in the column has a cell full of text. I would like all the columns to be the same height as the tallest item in the group. Using UICollectionViewCompositionalLayout I'm having a hard time getting the desired results.
I created a EqualHeightsUICollectionViewCompositionalLayout subcalss to check the cell attributes in layoutAttributesForElements and stores the largest cell height in a row.

Using the App Store Connect API how can you get the release date for an app? I've been able to use this endpoint to list a bunch of information, however the release date is not included.
As you can see in the JSON response posted below, it does have a "createdDate" but this corresponds to when the version was made in App Store Connect (Prepare for Submission), not when it was released to the store. This can be verified by looking in App Store connect.

The new UISheetPresentationControllerDetents look great but only the medium size is new. Many applications would benefit from a small or extra small detent that only takes up 1/4th or 1/8th of the screen. Google maps is a good example.
Is there anyway to add custom detents or specify a specific sheet height?
I have a sheet thats being presented in SwiftUI and the first time it's opened it automatically dismisses itself half a second later. Reopening it from then on works properly. Has anyone else experienced this and perhaps come up with a solution?
