Hi,
I have a workout app in the App Store which mirrors workout data between the phone and watch.
Since iOS 26.x I've been having issues and received reports of the mirroring no longer working. Users in iOS 18 have no problems with this functionality.
Bug description: A workout session is started from the phone app and starts mirroring to the watch companion device. The watch starts the workout session and then the mirroring session is disconnected / lost. Sending data to the companion device fails and ending the session on the phone doesn't end the session on the watch...essentially they become completely disconnected.
Please note I am testing this on physical devices...not simulators.
As a sanity check I've also tried the "Building a multidevice workout app" sample code and it has the same problem.
To re-create on the sample app, I start a workout from the phone, the watch workout starts and then the mirroring session seems to disconnect and is unable to send data.
This is the log from the "Building a multidevice workout app" sample code.
Successfully started workout

I have an iOS app with ExtensionFoundation. It runs well on my local device, but when I upload on the AppStore it gets rejected with:
Validation failed
Invalid Info.plist value. The value of the EXExtensionPointIdentifier key, AsheKube.app.a-Shell.localWebServer, in the Info.plist of “a-Shell.app/Extensions/localWebServer.appex” is invalid. Please refer to the App Extension Programming Guide at https://developer.apple.com/library/content/documentation/General/Conceptual/ExtensibilityPG/Action.html#/apple_ref/doc/uid/TP40014214-CH13-SW1. (ID: ae8dd1dd-8caf-4a48-9651-7a225faed4eb)
The Info.plist in my Extension is:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>EXAppExtensionAttributes</key>
<dict>
<key>EXExtensionPointIdentifier</key>
<string>com.example.example-extension</string>
</dict>
</dict>
</plist>
so the Info.plist that causes the issue has been automatically generated by Xcode. I can access it as well, and it says:

What should I do to be able to upload on the AppStore?
We have developed an app that communicates with an external reader using BLE, and the reader also supports NFC.
We are implementing a feature that uses PKPassLibrary.requestAutomaticPassPresentationSuppression to prevent the Wallet from appearing when unlocking a lock.
We have already completed the approval process for the entitlement required to enable Pass Presentation Suppression, referencing Apple’s documentation: https://developer.apple.com/documentation/passkit/pkpasslibrary/requestautomaticpasspresentationsuppression(responsehandler:)
In most cases, this works as expected and the Wallet popup does not appear.
However, in some cases — particularly when the app is running in the foreground — the Wallet still appears for users.
We have verified that the app bundle includes the required entitlement, and the Info.plist correctly specifies the Pass Presentation Suppression key set to true.
Could you please help us understand under what conditions this behavior might still occur, or if any additional configuration is required?
The "Cancel" button for VNDocumentCameraViewController is not displayed on iPadOS 26. This issue appears to be specific to iPad, as the button appears correctly on iPhone.
According to the documentation, using Scope(restriction: .none) can expose the extension point to third-party app extensions. Below is my implementation, which ultimately results in an error.
Code for declaring the extension point:
@available(iOS 26.0, *)
extension AppExtensionPoint {
@Definition
static var priceExtension: AppExtensionPoint {
Name("priceExtension")
UserInterface(false)
Scope(restriction: .none)
}
}
Code for locating the extension point:
monitor = try await AppExtensionPoint.Monitor(appExtensionPoint: .priceExtension)
When executing the code to locate the extension point, the following error occurs:
However, in practice, I found that declaring the extension point in this way results in an error when trying to locate it:
Error Domain=com.apple.extensionKit.errorDomain Code=19 "Failed to add observer" UserInfo={NSLocalizedDescription=Failed to add observer}
Since macOS 26, including the latest 26.1, the menu bar icon does not show up for our app called Plover which is built with PySide6 (based on Qt 6) and runs via a relocatable python that is packaged into the app. The code is open source and can be found on GitHub. The latest release, including the notarized DMG, can be found here.
When running the .app via the command below, the menu bar icon does show up but the process that is running is python3.13 and not Plover:
/Applications/Plover.app/Contents/MacOS/Plover -l debug
When running the app by just clicking on the application icon, the process is Plover but the menu bar icon is not showing - also not in the settings (Menu Bar > Allow in the Menu Bar). Before macOS 26, the menu bar icon was always shown.
Some pointers to potentially relevant parts of our code:
shell script that builds the .app
Info.plist
plover_launcher.c
trayicon.py
This problem might be related to this thread, including the discussion around Qt not calling NSApplicationMain.
What I'm trying to figure out is whether this is a problem with macOS 26, Qt 6, PySide6, or our code.
Any pointers are highly appreciated!

After upgrading to Xcode 16.4, the navigation arrow icon in the Report Navigator is no longer appearing for failed test cases within XCResult bundles. This icon, which allows developers to directly navigate to the specific line of code that caused a test failure, is now missing. This significantly hinders the debugging process for test automation engineers.
Details:
Xcode Version: 16.4 (issue started after upgrade)
Test Framework: XCTest
Test Environment: iOS simulators
Execution Method: The tests are executed on a Jenkins CI/CD server
XCResult Analysis: The generated .xcresult bundle is downloaded from the Jenkins server and opened locally on a Mac also running Xcode 16.4.
Observed Behavior:
The navigation arrow icon is missing, and there is no direct way to jump to the failure line from the report.
This issue appears to be a regression introduced in Xcode 16.4, as the navigation arrow was consistently present in previous versions. Any insights or workarounds would be greatly appreciated.
For the past several days every time I log in to to the Cloudkit dashboard I get Error looking up Developer Teams, Please sign out and try again. No amount of singing out and back in changes anything.
I'm working on an application for viewing AMF models on macOS, using RealityKit. AMF supports several different ways to color models, including per-vertex color (where the color of a triangle is interpolated from vertex to vertex) as well as per-face color (where the color of the triangle is the same across the entire face).
I'm trying to figure out how to support those color models using a RealityKit mesh. Apple's documentation (https://developer.apple.com/documentation/realitykit/modifying-realitykit-rendering-using-custom-materials) talks about per-vertex colors, but I haven't found a way to create a mesh that includes per-vertex colors, other than use a texture map (which might be the correct solution).
Can someone give me some pointers?
When I try to publish a new version of our app I am met by a popup
"Agreement Update"
"The Apple Developer Program License Agreement has been updated and needs to be reviewed. In order to update your existing apps and submit new apps, the Account Holder must review and accept the updated agreement by signing in to their account on the Apple Developer website."
I am not the account holder. But im confident he agreed to this around the 14-18 of October. He is not prompted with anything when logging in and going to agreements. Any suggestions?

Hi, I'm from India and payment has been deducted for the membership and I have received an email confirming my subscription of the program but I still cannot access my enrolment dashboard. It says "You'll receive an email soon" in my Apple Developer app under "Enrol" and it says Pending on my Apple Account on web. I don't understand why such as a small task is such a problematic thing for Apple. Need help understanding what's going on.
Is there any particular reason why ASWebAuthenticationSession doesn't have support for async/await? (example below)
do {
let callbackURL = try await webAuthSession.start()
} catch {
// handle error
}
I'm curious if this style of integration doesn't exist for architectural reasons? Or is the legacy completion handler style preserved in order to prevent existing integrations from breaking?
I've had a Unreal Engine project that uses libwebsocket to make a websocket connection with SSL to a server. Recently I made a build using Unreal Engine 5.4.4 on MacOS Sequoia 15.5 and XCode 16.4 and for some reason the websocket connection now fails because it can't get the local issuer certificate. It fails to access the root certificate store on my device (Even though, running the project in the Unreal Editor works fine, it's only when making a packaged build with XCode that it breaks)
I am not sure why this is suddenly happening now. If I run it in the Unreal editor on my macOS it works fine and connects. But when I make a packaged build which uses XCode to build, it can't get the local issuer certificate. I tried different code signing options, such as sign to run locally or just using sign automatically with a valid team, but I'm not sure if code signing is the cause of this issue or not.
This app is only for development and not meant to be published, so that's why I had been using sign to run locally, and that used to work fine but not anymore.
Any guidance would be appreciated, also any information on what may have changed that now causes this certificate issue to happen.
I know Apple made changes and has made notarizing MacOS apps mandatory, but I'm not sure if that also means a non-notarized app will now no longer have access to the root certificate store of a device, in my research I haven't found anything about that specifically, but I'm wondering if any Apple engineers might know something about this that hasn't been put out publicly.
Hello
Xcode 26.0.1 (17A400) Missing some Metal components
When building a program using Metal, it induces an unexpected error :
“error: error: cannot execute tool 'metal' due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain
Command CompileMetalFile failed with a nonzero exit code”
Which terminates the build
The fix given “xcodebuild -downloadComponent MetalToolchain” using sudo does not work
Did someone find a work around or could resolve the issue?
Many thanks
Jean
MacBook Air M4;

Xcode 26.0.1
Description:
I’m noticing that the code coverage metrics in Xcode 26 are not accurate compared to earlier versions.
In Xcode 15, the same set of unit tests shows around 38% coverage, but in Xcode 26, even though all the tests are running successfully (for example, the SegmentedUI test cases), the code coverage is displayed as 0%.
Has anyone else observed this behavior in Xcode 26?
Is there any known issue, workaround, or configuration change required to get the correct coverage report?
Environment:
Xcode 26
iOS 18 SDK
Unit tests running under XCTest
Any insights or suggestions would be appreciated.
Howdy,
I've been developing a packet tunnel extension meant to run on iOS and MacOS. For development I'm using xcodegen + xcodebuild to assemble a bunch of swift and rust code together.
I'm moving from direct TUN device management on Mac to shipping a Network Extension (appex). With that move I noticed that on some mac laptops NE fails to start completely, whilst on others everything works fine.
I'm using CODE_SIGN_STYLE: Automatic, Apple IDs are within the same team, all devices are registered as dev devices. Signing dev certificates, managed by xcode.
Some suspicious logs:
(NetworkExtension) [com.apple.networkextension:] Signature check failed: code failed to satisfy specified code requirement(s)
...
(NetworkExtension) [com.apple.networkextension:] Provider is not signed with a Developer ID certificate
What could be the issue? Where those inconsistencies across devices might come from?
I did an in app purchase in my development app and now I cannot get rid of it. It is a "monthly" subscription that seems to renew every 1 day.
I can see the subscription when I go to settings then tap on Subscriptions.
Then I tap the item and choose "Cancel Subscription", revealing a new modal sheet saying "Confirm Cancellation".
When I "Confirm", I get the popup:
"Your request is temporarily unable to be processed, please try again later".
However, this is anything BUT temporary, has gone on for a couple weeks now.
As such, I am unable to test subscriptions in my development app.
I've tried logging out, restarting, different devices, etc.
The phone is logged in under my primary user account, and I may not have been logged into sandbox email when I did the purchase.
Can someone forcibly remove it for me?
What is the correct way to implement scrolling in a looong list that uses ScrollView and LazyVstack
Imagine I have some api that returns a longs list of comments with replies
The basic usecase is to scroll to the bottom(to the last comment) Most of the time this works fine
But, imagine some of the comments have many replies like 35 or more (or even 300)
User expands replies for the first post, then presses scroll to bottom.
The scrollbar reaches the bottom and I see the blank screen.
Sometimes the scrollbar may jump for a while before lazyvstack finishes loading or until I manually scroll up a bit or all the way up and down
What should I do in this case? Is this the swiftui performance problem that has no cure?
Abstract example:
ScrollViewReader { proxy in
ScrollView {
LazyVStack {
ForEach(comments) { comment in
CommentView(comment: comment)
.id("comment-\(comment.id)")
}
}
}
}
struct CommentView: View {
let comment: Comment
@State var isExpanded = false
var body: some View {
VStack {
Text(comment.text)
if isExpanded {
RepliesView(replies: comment.replies) // 35-300+ replies
}
}
}
}
...
scroll
proxy.scrollTo("comment-\(lastComment.id)", anchor: .bottom)
I'm using Swift Data for an app that requires iOS 18.
All of my models conform to a protocol that guarantees they have a 'serverID' String variable.
I wrote a function that would allow me to pass in a serverID String and have it fetch the model object that matched. Because I am lazy and don't like writing the same functions over and over, I used a Self reference so that all of my conforming models get this static function.
Imagine my model is called "WhatsNew". Here's some code defining the protocol and the fetching function.
protocol RemotelyFetchable: PersistentModel {
var serverID: String { get }
}
extension WhatsNew: RemotelyFetchable {}
extension RemotelyFetchable {
static func fetchOne(withServerID identifier: String, inContext modelContext: ModelContext) -> Self? {
var fetchDescriptor = FetchDescriptor<Self>()
fetchDescriptor.predicate = #Predicate<Self> { $0.serverID == identifier }
do {
let allModels = try modelContext.fetch(fetchDescriptor)
return allModels.first
} catch {
return nil
}
}
}
Worked great! Or so I thought...
I built this and happily ran a debug build in the Simulator and on devices for months while developing the initial version but when I went to go do a release build for TestFlight, that build reliably crashed on every device with a message like this:
SwiftData/DataUtilities.swift:65: Fatal error: Couldn't find \WhatsNew. on WhatsNew with fields [SwiftData.Schema.PropertyMetadata(name: "serverID", keypath: \WhatsNew., defaultValue: nil, metadata: Optional(Attribute - name: , options: [unique], valueType: Any, defaultValue: nil, hashModifier: nil)), SwiftData.Schema.PropertyMetadata(name: "title", keypath: \WhatsNew., defaultValue: nil, metadata: nil), SwiftData.Schema.PropertyMetadata(name: "bulletPoints", keypath: \WhatsNew.)>, defaultValue: nil, metadata: nil), SwiftData.Schema.PropertyMetadata(name: "dateDescription", keypath: \WhatsNew., defaultValue: nil, metadata: nil), SwiftData.Schema.PropertyMetadata(name: "readAt", keypath: \WhatsNew.)>, defaultValue: nil, metadata: nil)]
It seems (cannot confirm) that something in the release build optimization process is stripping out some metadata / something about these models that makes this predicate crash.
Tested on iOS 18.0 and 18.1 beta.
How can I resolve this? I have two dozen types that conform to this protocol. I could manually specialize this function for every type myself but... ugh.
