I’m currently developing an application using WKWebView.
After updating to iOS 26.2 Developer Beta, the following Web API started returning false:
isUserVerifyingPlatformAuthenticatorAvailable
MDN: https://developer.mozilla.org/ja/docs/Web/API/PublicKeyCredential/isUserVerifyingPlatformAuthenticatorAvailable_static
This issue did not occur on iOS 26.1 — it only happens on the beta version.
Has anyone else encountered this problem or is aware of any related changes?
OS: iOS 26.2 beta 3 (23C5044b)

The same code built in a regular Mac app (with UI) does get paired.
The characteristic properties are [.read, .write, .notify, .notifyEncryptionRequired]
The characteristic permissions are [.readEncryptionRequired, .writeEncryptionRequired]
My service is primary.
In the iOS app (central) I try to read the characteristic, but an error is reported: Error code: 5, Description: Authentication is insufficient.

Hey,
I am just about to prepare my app for Swift 6, and facing the issue that UserDefaults is not Sendable. The documentation states that its thread safe, so I am wondering, why is it not marked as Sendable? Was it just forgotten? Is it safe to mark it as nonisolated(unsafe) or @unchecked Sendable?
Hi, I have been recently debugging the BGContinuedProcessingTask API and encountered some of the following issues. I hope you can provide some answers:
First, let me explain my understanding of this API. I believe its purpose is to allow an app to trigger tasks that can be represented with progress indicators and require a certain amount of time to complete.
After entering the background, these tasks can continue to be completed through the BGContinuedProcessingTask, preventing the system from terminating them before they are finished.
In the launchHandler of the registration process, we only need to do a few things:
Determine whether the actual business processing is still ongoing.
Update the progress, title, and subtitle.
Handle the expirationHandler.
Set the task as completed.
Here are some issues I encountered during my debugging process:
After I called register and submit, the BGContinuedProcessingTask could not be triggered. The return values from my API calls were all normal.
I tried different device models, and some could trigger the task normally, such as the 15 Pro Max and 12 Pro Max. However, there were also some models, such as the 17 Pro, 15 Pro, and 15, that could not trigger the task properly. Moreover, there was no additional error information to help locate the issue.
The background task failed unexpectedly, but my app was still running normally. As I mentioned above, my launchHandler only retrieves the actual business status and updates it.
If a background task fails unexpectedly while the app is still running normally, it can mislead users and degrade the user experience of the app.
Others have also mentioned the issue of inconsistent behavior on devices that do not support Dynamic Island. On devices that support Dynamic Island,
when a task is triggered in the foreground, the app does not immediately display a pop-up notification within the app. However, on devices that do not support Dynamic Island,
the app directly displays a pop-up notification within the app, and this notification does not disappear when switching between different screens within the same app.
The user needs to actively swipe up to dismiss it. I think this experience is too intrusive for users. I would like to know whether this will be maintained in the future or if there is a plan to fix it.
On devices that do not support Dynamic Island, using the beta version 26.1 of the system,
if the system is in dark mode but the app triggers a business interface in white, the pop-up notification will have the same color as the current page, making it difficult to read the content inside the pop-up.
Users can actively stop background tasks by using the stop button, or the system can also stop tasks automatically when resources are insufficient or when a task is abnormal.
However, according to the current API, all these actions are triggered through the expirationHandler.
Currently, there is no way to distinguish whether the task was stopped by the user, by the system due to resource insufficiency, or due to an abnormal task.
I would like to know whether there will be more information provided in the future to help distinguish these different scenarios.
I believe that the user experience issues mentioned in points 2 and 3 are the most important. Please help to answer the questions and concerns above. Thank you!
I have the following view hierarchy in my app:
[UINavigationController] -> [MainViewController] -> [MyTabBarController] -> [DashboardViewController]
In my MainViewController I have a button that pushes the MyTabBarController onto the navigation controllers stack. In the tab bar controller I only have one tab in this example showing the DashboardViewController.
That all works fine, and when I tap the back button on MyTabBarController, everything works fine and the MainViewController is shown again. The UI works exactly how I want it, but when I load up the 'Debug Memory Graph' view, I can see that my DashboardViewController is still in memory and it seems the UITab has a reference to it. The MyTabBarController is NOT in memory anymore.
MyTabBarController is very simple:
class MyTabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
self.mode = .tabSidebar
var allTabs:[UITab] = []
let mainTab = UITab(title: "Dashboard",
image: UIImage(systemName: "chart.pie"),
identifier: "dashboard",
viewControllerProvider: { _ in
return UINavigationController(rootViewController: DashboardViewController())
})
allTabs.append(mainTab)
setTabs(allTabs, animated: false)
}
}
And the DashboardViewController is empty:
class DashboardViewController: UIViewController {
}
The only reason I created as a seperate class in this example is so I can easily see if it's visible in the memory debug view.
I have uploaded the simple sample app to GitHub:
https://github.com/fwaddle/TabbarMemoryLeakCheck
Anyone have any suggestions?
Here is a screen grab of the memory debug view showing the UITab having a reference to the DashboardViewController even though MyTabBarController has been dealloc'd:

Running iOS 26.4 and now the smart display zoom feature is no longer showing on my 2024 RAM Uconnect 5 12” radio. Is there anyway to fix this issue?
I'm trying to train a text classifier model in Create ML. The Create ML app/framework offers five algorithms. I can successfully train the model with all of the algorithms except the BERT transfer learning option. When I select this algorithm, Create ML simply stops the training process immediately after the initial feature extraction phase (with no reported error).
What I've tried:
I tried simplifying the dataset to just a few classes and short examples in case there was a problem with the data.
I tried experimenting with the number of iterations and language/script options.
I checked Console.app for logged errors and found the following for the Create ML app:
error 10:38:28.385778+0000 Create ML Couldn't read event column - category is invalid. Format string is : <private>
error 10:38:30.902724+0000 Create ML Could not encode the entity <private>. Error: <private>
I'm not sure if these errors are normal or indicative of a problem. I don't know what it means by the "event" column – I don't have an event column in my data and I don't believe there should be one. These errors are not reported when using the other algorithms.
Given that I couldn't get the app to work with BERT, I switched over to the CreateML framework and followed the code samples given in the documentation. (By the way, there's an error in the docs: the line let (trainingData, testingData) = data.stratifiedSplit(on: "text", by: 0.8) should be stratifying on "label", not on "text").
The main chunk of code looks like this:
var parameters = MLTextClassifier.ModelParameters(
validation: .split(strategy: .automatic),
algorithm: .transferLearning(.bertEmbedding, revision: 1),
language: .english
)
parameters.maxIterations = 100
let sentimentClassifier = try MLTextClassifier(
trainingData: trainingData,
textColumn: "text",
labelColumn: "label",
parameters: parameters
)
Ultimately I want to train a single multilingual model, and I believe that BERT is the best choice for this. The problem is that there doesn't seem to be a way to choose the multilingual Latin script option in the API. In the Create ML app you can theoretically do this by selecting the Latin script with language set to "Automatic", as recommended in this WWDC video (relevant section starts at around 8:02). But, as far as I can tell, ModelParameters only lets you pick a specific language.
I presume the framework must provide some way to do this, since the Create ML app uses the framework under the hood, but I can't see a way to do it. Another possibility is that the Create ML app might be misrepresenting the framework – perhaps selecting a specific language in the app doesn't actually make any difference – for example, maybe all Latin languages actually use the same model under the hood and the language selector is just there to guide people to the right choice (but this is just my speculation).
Any help would be much appreciated! If possible, I'd prefer to use the Create ML app if I can get the BERT option to work – is this actually working for anyone? Or failing that, I want to use the framework to train a multilingual Latin model with BERT, so I'm looking for instructions on how to choose that specific option or confirmation that I can just choose .english to get the correct Latin multilingual model.
I'm running Xcode 26.2 on Tahoe 21.1 on an M1 Pro MacBook Pro. I have version 6.2 of the Create ML app.

I've encountered an issue where we need multiple domain associations with separate Apple Pay implementations.
Briefly, we have a /.well-known/apple-developer-merchantid-domain-association already setup with Stripe, and now we need another, different version of the file to get setup with FreedomPay. FreedomPay insists this file represents a three-way relationship between all parties and I have no reason to disbelieve them.
I'm wondering if anyone has encountered this or if there is a standard procedure. I'm currently trying to find documentation on the exact way Apple Pay verification interacts with this file to see if we can produce it dynamically.
I am preparing for Swift Student Challenge, but it seems like the iPad Playground app still not support the latest SDK.
I can't use frameworks like FoundationModel, etc., directly in playground app
My playground for this year would require iPad environment since it uses PencilKit, ARKit, etc., and I also want to use the latest tech + the liquid glass UI
Right now, I develop the project as a normal Xcode project, and I am wondering how do I post it?
As Xcode playground, it must run on macOS
As Swift Playground project, the iPad version of Playground does not support latest APIs and it can't compile

Usually, when you call fetchRecordZoneChanges with the previous change token, you get a list of the record ID’s that have been deleted since your last fetch.
But if you get a changeTokenExpired error because it‘s been too long since you last fetched, you have to call fetch again without a token.
For my specific application, I still need to know, though, if any records have been deleted since my last sync. How can I get that information if I no longer have a valid change token?
Hi there,
When I deploy my app to the iPhone for testing, I get the following error:
Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the

executable is no longer valid.)
My account was mistakenly deactivated by Apple last month. After appealing, Apple restored it at the end of last month. Currently, my Apple Developer account seems to be working fine.
Today, I recreated the developer certificate and identifier, added the account in XCode, everything seemed fine, and I clicked the XCode button (Start the active scheme). The build was successful, but I got the error:
Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.4gpZFc/extracted/c_mll.app : 0xe8008018 (The identity used to sign the executable is no longer valid.)
Both my certificate and identifier were created just a few hours ago and show no issues.
Before my account was deactivated, everything was working fine.
I used a regular non-Apple developer account in XCode and performed the same steps, and it worked fine.
I looked at relevant posts on the forum and tried the suggestions, but none of them solved my problem.
There is a problem with the launchscreen of my application on iPadOS 26.
After release of the windowed mode feature the launchscreen of my fullscreen landscape-only application is being cropped and doesn't stretch to screen's size when the device is in the portrait mode.
How can I fix this?

We have an app that controls InDesign Desktop and InDesignServer via hundreds of AppleScripts. Some macOS security updates a while back dictated that we start communicating with other apps via ScriptingBridge. We couldn't afford to convert the hundreds of AppleScripts into direct ScriptingBridge nomenclature, so we opted to keep them as is and instead tell the external apps to:
[app doScript:<the script text> language:InDesignScLgApplescriptLanguage withArguments:nil undoMode:InDesignESUMScriptRequest undoName:@"blah"]
There are a handful of scripts that we did convert to direct ScriptingBridge.
There are times (and under the right circumstances, it's repeatable) when a certain script will have run perfectly dozens of times, and then it will throw errOSAInternalTableOverflow.
We create a new SBApplication for every job (which could be a single instance of Desktop or the multiple instances of Server).
Why is this error happening seemingly randomly? Is there anything we can do to work around or prevent this?

In the NetworkExtension framework, for the NETransparentProxyProvider and NEDNSProxyProvider classes: when calling the open func writeDatagrams(_ datagrams: [Data], sentBy remoteEndpoints: [NWEndpoint]) async throwsin the NEDNSProxyProvider class, and the open func write(_ data: Data, withCompletionHandler completionHandler: @escaping @Sendable ((any Error)?) -> Void)in the NETransparentProxyProvider class, errors such as "The operation could not be completed because the flow is not connected" and "Error Domain=NEAppProxyFlowErrorDomain Code=1 "The operation could not be completed because the flow is not connected"" occur.
Once this issue arises, if it occurs in the NEDNSProxyProvider, the entire system's DNS will fail to function properly; if it occurs in the NETransparentProxyProvider, the entire network will become unavailable.
On the following developer account page, you have the ability to update your address information, but it does not appear to be working for me.
If you go to https://developer.apple.com/account and scroll down the page. You come to a section called Membership Details with a link to update your information. When you click on this link it shows a dialog which has two choices. One is for Change Contact Details and the other is for Switch to Organization Membership. When I attempt to Select Change Contact Details. Nothing happens at all. No screen is shown. Nothing, whatsoever.
Please advise what the problem might be thank you. I need to change my contact address.

I am developing an application that uses NetworkExtension (Local PUSH function) And VoIP(APNs) PUSH.
Nowadays, I found a problem on this app doesn't handle incoming call of Local PUSH when receiving a Local PUSH after receiving an APNs PUSH.
My confimation result of my app and server log is below.
11:00 AM:
my server(PBX) requests a VoIP(APNs) PUSH notification to the APNs.
But my app does not receive the VoIP(APNs) PUSH.
At this time, my app is running on LAN (Wi-Fi without internet connection), as a result, NetworkExtension was running. so I think this is normal behaviour.
14:55:11 PM:
There is an incoming call from the my server(PBX) via local net, and NetworkExtension calls iOS API(API name is reportIncomingCall).
However, iOS does not call the delegate didReceiveIncomingCallWithUserInfo for the reportIncomingCall.
14:55:11 PM:
At almost the same time, iOS calls the delegate cdidReceiveIncomingPushWithPayload of VoIP PUSH.
(instead of call the delegate didReceiveIncomingCallWithUserInfo for the reportIncomingCall?)
And the content of this VoIP(APNs) PUSH was the incoming call at "11:00 AM".
In other words, the VoIP(APNs) PUSH at 11:00 AM is stuck inside iOS, and at 14:55:11 PM, from NetworkExtension reports it.
I feel there is a problem on iOS doesn't handle incoming call of Local PUSH when receiving a Local PUSH after receiving an VoIP(APNs) PUSH.
Would you tell me Apple's opioion about this?
If this is known problem, Please tell me about it.

We recently migrated our entire product to Apple Unified Logging due to the various benefits it provides. However we immediately started hitting the "log quarantine" problem ("QUARANTINED DUE TO HIGH LOGGING VOLUME"). This is partly because we are indeed over logging in a few cases (which we have to work on fixing), but also partly because it's a complicated product with potentially hundreds of libraries, and some of the code can legitimately be very busy. For example we have a system extension that's implemented both as a NetworkExtension client and an EndpointSecurity client, if we were to log decent information about each network or file system event so we can troubleshoot something, they are bound to be high volume logs.
Now when our app is running in a normal user environment, this is not a problem. We can disable certain heavy log levels, or at least disable persisting for certain logs (one of the benefits of Apple Unified Logging we really like is that it allows very flexible controls, log config command, OSLogPreferences, configuration profile, we can employ whatever that suits a specific case). But ultimately, the question is what if we end up with a troubleshooting case we don't know exactly where a problem is so we just need the full logs at debug level? And not only just enabled, but because we might not know when the issue can happen either we also need to persist the full set of logs for as long as possible? We will start hitting log quarantine again. Granted this is a very extreme case, but if worst comes to worst, how can we even do that with Apple Unified Logging? Is there an option that allows us to override the quarantine, if but temporarily?
I've searched a few relevant forum posts, some of which described log quarantine but no one had mentioned any solution for it (besides having to stop logging so much from the app but as I explained we do have legitimate cases where log volume can still be huge). I've also read The Eskimo's "Your Friend the System Log" and browsed some of the troubleshooting config profiles provided by Apple hoping to discover some hidden payloads but found none so far.
There is an OSLogRateLimit environment variable that I noticed if I run a launchctl print system/<a-launch-daemon-lable> and it's usually 64. Is this something relevant? And knowing Apple it's probably something that can't be tampered with?
