Hello,
I have noticed a performance drop on SpriteKit-based projects running on iOS 26.0 (23A341).
Below is a SpriteKit scene used to test framerate on different devices:
import SpriteKit
import SwiftUI
class BareboneScene: SKScene {
override func didMove(to view: SKView) {
size = view.bounds.size
anchorPoint = CGPoint(x: 0.5, y: 0.5)
backgroundColor = .darkGray
let roundedSquare = SKShapeNode(rectOf: CGSize(width: 150, height: 75), cornerRadius: 12)
roundedSquare.fillColor = .systemRed
roundedSquare.strokeColor = .black
roundedSquare.lineWidth = 3
addChild(roundedSquare)
let action = SKAction.rotate(byAngle: .pi, duration: 1)
roundedSquare.run(.repeatForever(action))
}
}
struct BareboneSceneView: View {
var body: some View {
SpriteView(
scene: BareboneScene(),
debugOptions: [.showsFPS]
)
.ignoresSafeArea()
}
}
#Preview {
BareboneSceneView()
}
The scene is very simple, yet framerate drops to ~40 fps as shown by the Metal HUD. Tested on:
iPhone 13, iOS 26.0: framerate drops to 40 fps. Sometimes it runs at near 60fps. But if the screen is touched repeatedly, the framerate drops to 40-50 fps again.
iPhone 11 Pro, iOS 26.0: ~40fps.
iPad 9th Gen, iOS 18.6.2: 60fps, no issues.
See screenshots attached. These numbers were observed by me and members of our beloved SpriteKit Discord server.
Thank you for your attention.

Hi all,
I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target.
Here’s what I’ve done:
App Info.plist:
Declared com.makeprog.vpvm as a UTI conforming to com.apple.package.
Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes.
Spotlight Importer Extension:
Added a new macOS target using the Spotlight Import Extension template.
Set the NSExtensionPointIdentifier to com.apple.spotlight.import.
Used CSSupportedContentTypes = com.makeprog.vpvm.
Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription.
Other steps:
Verified that the .appex is embedded under Contents/PlugIns/.
Confirmed it appears in mdimport -e output with correct UTI.
Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get:
Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn.
The extension is never invoked. I’ve also tried:
Ensuring the .vpvm file is a valid directory bundle.
Restarting Spotlight / rebuilding index.
Ensuring the app and extension are properly signed.
Tried installing the app in test virtual machine
Question:
Has anyone successfully used CSImportExtension for custom UTIs?
Is there something additional I need to do for the extension to be recognized and triggered?
Any advice or examples would be greatly appreciated!
Thanks in advance.
Already filed a feedback in case this is a bug, but posting here in case I'm doing something wrong?
I'd like the search field to automatically be displayed with the keyboard up when the view appears. This sample code works in iOS 18, but it does not work in iOS 26 beta 7
I also tried adding a delay to setting searchIsFocused = true but that did not help
struct ContentView: View {
var body: some View {
NavigationStack {
NavigationLink(destination: ListView()) {
Label("Go to list", systemImage: "list.bullet")
}
}
.ignoresSafeArea()
}
}
struct ListView: View {
@State private var searchText: String = ""
@State private var searchIsPresented: Bool = false
@FocusState private var searchIsFocused: Bool
var body: some View {
ScrollView {
Text("Test")
}
.searchable(text: $searchText, isPresented: $searchIsPresented, placement: .automatic, prompt: "Search")
.searchFocused($searchIsFocused)
.onAppear {
searchIsFocused = true
}
}
}
The following code worked as expected on iOS 26 RC, but it no longer works on the official release of iOS 26.
Is there something I need to change in order to make it work on the official version?

BGTaskScheduler.shared.register(
forTaskWithIdentifier: taskIdentifier,

Hi everyone,
I’m encountering a serious reliability issue with message passing in my Safari extension on iOS 18.4.1 and iOS 18.5
In my extension, I use the standard messaging API where the background script sends a message to the content scrip. The content script is listening using:
browser.runtime.onMessage.addListener(handler);
This setup has been working reliably in previous versions of iOS, but since updating to iOS 18.4.1 and iOS 18.5, I’ve noticed that messages sent from the background script are not consistently received by the content script. From my logs, I can confirm that:
The background script is sending the message.
The content script’s listener is not always triggered.
There are no errors or exceptions logged in either script.
It seems as if browser.runtime.onMessage.addListener is either not getting registered in time or failing silently in some instances.
This issue is intermittent and does not occur all the time.
Has anyone else experienced similar issues in iOS 18.4.1 and 18.5? Are there any known changes or workarounds for ensuring reliable communication between background and content scripts in this version?
Any help or insights would be greatly appreciated.
Thanks!
There appears to be some unexplained change in behaviour in the recent version of macos 15.6.1 which is causing the BSD socket sendto() syscall to no longer send the data when the source socket is bound to a IPv4-mapped IPv6 address.
I have attached a trivial native code which reproduces the issue. What this reproducer does is explained as a comment on that code's main() function:
// Creates a AF_INET6 datagram socket, marks it as dual socket (i.e. IPV6_V6ONLY = 0),
// then binds the socket to a IPv4-mapped IPv6 address (chosen on the host where this test runs).
//
// The test then uses sendto() to send some bytes. For the sake of this test, it uses the same IPv4-mapped
// IPv6 address as the destination address to sendto(). The test then waits for (a maximum of) 15 seconds to
// receive that sent message by calling recvfrom().
//
// The test passes on macos (x64 and aarch64) hosts of versions 12.x, 13.x, 14.x and 15.x upto 15.5.
// Only on macos 15.6.1 and the recent macos 26, the test fails. Specifically, the first message that is
// sent using sendto() is never sent (and thus the recvfrom()) times out. sendto() however returns 0,
// incorrectly indicating a successful send. Interesting, if you repeat sendto() a second message from the
// same bound socket to the exact same destination address, the send message is indeed correctly sent and
// received immediately by the recvfrom(). It's only the first message which goes missing (the test uses
// unique content in each message to be sure which exact message was received and it has been observed that
// only the second message is received and the first one lost).
//
// Logs collected using "sudo log collect --last 2m" (after the test program returns) shows the following log
// message, which seem relevant:
// ...
// default kernel cfil_hash_entry_log:6088 <CFIL: Error: sosend_reinject() failed>:
// [86868 a.out] <UDP(17) out so 59faaa5dbbcef55d 127846646561221313 127846646561221313 age 0>
// lport 65051 fport 65051 laddr 192.168.1.2 faddr 192.168.1.2 hash 201AAC1
// default kernel cfil_service_inject_queue:4472 CFIL: sosend() failed 22
// ...
//
As noted, this test passes without issues on various macosx version (12 through 15.5), both x64 and aarch64 but always fails against 15.6.1. I have been told that it also fails on the recently released macos 26 but I don't have access to such host to verify it myself.
The release notes don't usually contain this level of detail, so it's hard to tell if something changed intentionally or if this is a bug. Should I report this through the feedback assistant?
Attached is the source of the reproducer, run it as:
clang dgramsend.c
./a.out
On macos 15.6.1, you will see that it will fail to send (and thus receive) the message on first attempt but the second one passes:
...
created and bound a datagram dual socket to ::ffff:192.168.1.2:65055
::ffff:192.168.1.2:65055 sendto() ::ffff:192.168.1.2:65055
---- Attempt 1 ----
sending greeting "hello 1"
sendto() succeeded, sent 8 bytes
calling recvfrom()
receive timed out
---------------------
---- Attempt 2 ----
sending greeting "hello 2"
sendto() succeeded, sent 8 bytes
calling recvfrom()
received 8 bytes: "hello 2"
---------------------
TEST FAILED
...
The output "log collect --last 2m" contains a related error (and this log message consistently shows up every time you run that reproducer):
...
default kernel cfil_hash_entry_log:6088 <CFIL: Error: sosend_reinject() failed>:
[86248 a.out] <UDP(17) out so 59faaa5dbbcef55d 127846646561221313 127846646561221313 age 0>
lport 65055 fport 65055 laddr 192.168.1.2 faddr 192.168.1.2 hash 201AAC1
default kernel cfil_service_inject_queue:4472 CFIL: sosend() failed 22
...
I don't know what it means though.

For years, my app has been receiving XLSX files from other apps using the share command.
For example, in an email, I use the share command on an xlsx attachment and send it to my app.
From my app, I go to the Documents/Inbox folder and find the file.
This mechanism has broken! And I'm not talking about an app compiled with XCode26, but simply installing my app, still compiled with XCode16, on iPadOS26.
It seems that the operating system no longer puts files in the Inbox. Is this true?
With macOS Tahoe, Launchpad has been replaced by an App Library–style mode within Spotlight. While the alleged intention is UX consistency across the Apple ecosystem, the result is both a catastrophic usability regression and a radical break in consistency with iOS and iPadOS.
Predefined App Library categorization is functionally incoherent:
On iOS and now macOS, Apple’s predefined App Library categories place apps with seemingly identical functionality into unrelated groups—for example, 3D scanning tools scattered across Education, Utilities, and Productivity. Instead of making apps easier to find, this effectively creates a labyrinth that users must traverse to locate apps whose names and icons they may not recall. However Apple defines its app categories, they are not only inconsistent but also hopelessly inadequate for the long tail of real-world applications and user workflows.
Loss of user control:
Launchpad enabled users to group and organize applications according to their workflows. This aligns with Apple’s own Human Interface Guidelines, which emphasize user control, discoverability, and predictable behavior. The new Spotlight interface removes that flexibility, locking users into predefined categories that both impede and mislead—and cannot be overridden.
Consistency across platforms is broken:
If the goal was to unify iOS, iPadOS, and macOS, this approach actually undermines consistency. On iOS and iPadOS, users can still rely on a customizable Home Screen—a Launchpad-like experience—as their primary way of launching apps. In Tahoe, that option has been removed. macOS now forces users to depend exclusively on Spotlight with App Library categories, while eliminating the very feature that was consistent across platforms.
Catastrophic impact on my workflow:
As an interdisciplinary artist working in 2D, 3D, and time-based media, as well as coding, I make extensive use of a constantly changing array of AI tools and experiment with many new apps and web services, which I often turn into Web Apps. I cannot possibly recall the names of every native and web app on my system. I need predictable access to groups of related tools. Tahoe’s new auto-categories split those apps apart arbitrarily, slowing me down and interrupting established workflows, forcing me to navigate the aforementioned labyrinth just to find what I need.
Proposal:
A constructive way forward High-level objective:
Simply restore Launchpad—or restore the ability to customize app categories/folders and manually assign apps to them, overriding or augmenting the predefined categories. This ensures users can launch apps according to their workflow, without needing to remember exact names or icons.
Possible solutions:
Allow manual subfolders within Applications, represented hierarchically in Spotlight.
Provide a fullscreen Launchpad-like organizer (with uninstall via long-click, etc.), either as a replacement or toggleable option.
Retain Apple’s auto-categories for those who prefer them, but let users override or augment them with their own.
In summary:
Tahoe eliminates a working, consistent paradigm (Launchpad/Home Screen) and forces reliance on an App Library system that categorizes poorly and cannot be customized. This is both a step backwards in functionality and a break in cross-platform consistency. A constructive solution is to restore Launchpad—or at least restore the ability for users to organize apps in ways that fit their workflows.
From what I’ve seen, this issue has been around since macOS 13 and can be reproduced reliably. It happens with some apps like Music, Notes, and Google Chrome.
Here’s how to see it:
1.Make sure “Minimize windows into application” is enabled in System Settings, or just open a minimized app later directly from its application icon.
2.Open one of the apps mentioned above.
3.Minimize it.
4.Click the minimized app in the Dock to restore it.
You’ll notice the GUI flashes for a moment and the minimize animation plays again.

Dear Apple Support,
We are encountering an issue with deep linking on iOS 26 when using Safari and App Store redirection. Below are the detailed steps to reproduce the problem:
The app is not installed on the device.
User clicks on a Branch link:
For example:- https://qewed.app.link/99u88ef9f?uuid=88dbwh5ubd4b
Safari opens and displays the fallback page.
User taps on “Get the App”, which navigates to the App Store.
User installs and opens the app.
Expected Behavior:
The app should receive the Branch link parameters (in this case, uuid=88dbwh5ubd4b) upon first open.
Actual Behavior:
The app opens successfully, but the uuid parameter is not passed to the app.
This issue seems specific to the Safari → App Store → App flow on iOS 26, as other flows behave correctly.
Could you please advise whether this is a known issue or if there are recommended adjustments on our side to ensure parameters are consistently delivered after App Store redirection?
Note: We are using Branch SDK version 3.11.0 (Cocoapods dependency)
Thank you for your assistance.
Hi,
I want to understand how Per-App VPN can be configured on iOS.
Specifically:
Is Per-App VPN something that can be controlled directly from code (inside an app), or does it always require MDM / configuration profiles (.mobileconfig)?
If it requires a configuration profile, how can I specify which apps (by bundle identifier) should use the VPN?
Is it possible to let users dynamically choose apps for Per-App VPN, or is this strictly managed by MDM?
My goal is to make sure that only apps selected by user dynamically use the VPN connection, while other apps continue to use the normal network.
Any official Apple documentation, examples, or guidance would be greatly appreciated.

I’ve noticed a strange bug in Xcode 16 and Swift. When a preview is rendering and hasn’t finished yet and you run an app to debug, Xcode is launching two instances of the app. Has anyone else noticed this issue? If you let the preview finish rendering before running the app, this doesn’t happen. Very odd.
Hey there,
Link to the sample project: https://github.com/dev-loic/AppleSampleScrolling
Context
We are working on creating a feed of posts in SwiftUI. So far, we have successfully implemented a classic feed that opens from the top, with bottom pagination — a standard use case.
Our goal, however, is to allow the feed to open from any post, not just the first one.
For example, we would like to open the feed directly at the 3rd post and then trigger a network call to load elements both above and below it.
Our main focus here is on preserving the scroll position while opening the screen and waiting for the network call to complete.
To illustrate the issue, I created a sample project (attached) with two screens:
MainView, which contains buttons to open the feed in different states.
ScrollingView, which initially shows a single element, simulates a 3-second network call, and then populates with new data depending on which button was tapped.
I am currently using Xcode 26 beta 6, but I can also reproduce this issue on Xcode 16.3.
Tests on sample project
I click on a button and just wait the 3 seconds for the call.
In this scenario, I expect that the “focused item” stays at the exact same place on the screen. I also expect to see items below and above being added.
Simulator iPhone 16 / iOS 18.4 with itemsHeight = 100
position = 0, 1, 2, 3 ⇒ works as expected
position = 4, 5, 6, 7, 8, 9 ⇒ scroll is reset to the top and we loose the focused item
Simulator iPhone 16 / iOS 18.4 with itemsHeight = 500
position = 0, 1, 2, 3, 4 ⇒ works as expected
position = 5, 6, 7 ⇒ I have a glitch (the focused element moves on the screen) but the focused element is still visible
position = 8, 9 ⇒ scroll is reset to the top and we loose the focused item
Simulator iPhone 16 / iOS 26 with itemsHeight = 100 or 500
position = 0, 1, 2, 3, 4 ⇒ works as expected
position = 5, 6, 7, 8, 9 ⇒ I have a glitch (the focused element moves on the screen) but the focused element is still visible
Device iPhone 15 / iOS 26 with itemsHeight = 100
position = 0, 1, 2, 3, 4 ⇒ works as expected
position = 5, 6, 7, 8, 9 ⇒ I have a glitch (the focused element moves on the screen) but the focused element is still visible
Device iPhone 15 / iOS 26 with itemsHeight = 500
position = 0, 1, 2, 3 ⇒ works as expected
position = 4, 5, 6, 7, 8, 9 ⇒ I have a glitch (the focused element moves on the screen) but the focused element is still visible
Not any user interaction
Moreover, in this scenario, the user does not interact with the screen during the simulated network call. Regardless of the situation, if the ScrollView is in motion, its position always resets to the top. This behavior prevents us from implementing automatic pagination when scrolling upward, which is ultimately our goal.
My conclusion so far
As far as I know it seems not possible to have both keeping scroll possible and upward automatic pagination using a SwiftUI LazyVStack inside a ScrollView.
This appears to be standard behavior in messaging apps or other feed-based apps, and I’m wondering if I might be missing something.
Thank you in advance for any guidance you can provide on this topic.
Cheers
On iOS when I run my Autofill extension target from Xcode and attach to Safari, Swift print() statements appear in the Xcode console log. If I run the same extension on MacOS Sequoia, no log messages appear. The header strip in the debugger area remains blank. Anyone know how to see these log messages?
In both cases, the scheme is set to Debug build, and "Debug Executable" is not selected. In fact, for iOS the "Debug Executable" is grayed out. When I set Debug Executable on the MacOS run, I get failure to attach with a warning about permission to debug Safari.
I noticed that when I have a fullscreen window in macOS 26, sidebars look like they are cut off at the top: they suddenly stop where the title bar/toolbar would appear when moving the mouse to the top of the screen, leaving a wide empty gap. Am I the only one who finds this ugly? Is this intended, or is there a workaround?
This is how it looks in fullscreen (the sidebar borders are not easy to distinguish, look for the drop shadow):
And this when moving the mouse to the top screen border to show the menu bar:
I created FB20291636.
@main
class AppDelegate: NSObject, NSApplicationDelegate, NSWindowDelegate {
func applicationDidFinishLaunching(_ aNotification: Notification) {
let splitViewController = NSSplitViewController()
splitViewController.addSplitViewItem(NSSplitViewItem(sidebarWithViewController: ViewController()))
splitViewController.addSplitViewItem(NSSplitViewItem(viewController: ViewController()))
let window = NSWindow(contentViewController: splitViewController)
window.styleMask = [.titled, .closable, .miniaturizable, .resizable, .fullSizeContentView]
window.toolbar = NSToolbar()
window.delegate = self
window.makeKeyAndOrderFront(nil)
}
func window(_ window: NSWindow, willUseFullScreenPresentationOptions proposedOptions: NSApplication.PresentationOptions = []) -> NSApplication.PresentationOptions {
return [.autoHideToolbar, .autoHideMenuBar, .fullScreen]
}
}
class ViewController: NSViewController {
override func loadView() {
let stack = NSStackView(views: [
NSTextField(labelWithString: "asdf")
])
stack.orientation = .vertical
stack.alignment = .leading
view = stack
view.frame = CGRect(x: 0, y: 0, width: 300, height: 300)
}
}
I have a TabView (no modifiers) as the top-level view in my app. Starting with iOS 26 it starts off partially "under" the Status Bar, and then repositions if I switch between apps.
Starting Point
After Switching To/From Another App
In the simulator, pressing "Home" and then reopening the app will fix it.
Anyone else seeing something similar? Is there a modifier I'm missing on TabView that might prevent this behaviour?
Thanks!
