I am trying to migrate an app to use Network framework for p2p connection. I came across this great article for migrating to Network framework however this doesnt use the new structured concurrency. This being introduced with iOS 26, there doesnt seem to be any sample code available on how to use the new classes. I am particularly interested in code samples showing how to add TLS with PSK encryption support and handling of switching between Wifi and peer to peer interface with the new structured concurrency supported classes. Are there any good resources I can refer on this other than the WWDC video?

I can't seem to get hardware tag checks to work in an app launched without the special "Hardware Memory Tagging" diagnostics. In other words, I have been unable to reproduce the crash example at 6:40 in Apple's video "Secure your app with Memory Integrity Enforcement".
When I write a heap overflow or a UAF, it is picked up perfectly provided I enable the "Hardware Memory Tagging" feature under Scheme Diagnostics.
If I instead add the Enhanced Security capability with the memory-tagging related entitlements:
I'm seeing distinct memory tags being assigned in pointers returned by malloc (without the capability, this is not the case)
Tag mismatches are not being caught or enforced, regardless of soft mode
The behaviour is the same whether I launch from Xcode without "Hardware Memory Tagging", or if I launch the app by tapping it on launchpad. In case it was related to debug builds, I also tried creating an ad hoc IPA and it didn't make any difference.
I realise there's a wrinkle here that the debugger sets MallocTagAll=1, so possibly it will pick up a wider range of issues. However I would have expected that a straight UAF would be caught. For example, this test code demonstrates that tagging is active but it doesn't crash:
#define PTR_TAG(p) ((unsigned)(((uintptr_t)(p) >> 56) & 0xF))
void *p1 = malloc(32);
void *p2 = malloc(32);
void *p3 = malloc(32);
os_log(OS_LOG_DEFAULT, "p1 = %p (tag: %u)\n", p1, PTR_TAG(p1));
os_log(OS_LOG_DEFAULT, "p2 = %p (tag: %u)\n", p2, PTR_TAG(p2));
os_log(OS_LOG_DEFAULT, "p3 = %p (tag: %u)\n", p3, PTR_TAG(p3));
free(p2);
void *p2_realloc = malloc(32);
os_log(OS_LOG_DEFAULT, "p2 after free+malloc = %p (tag: %u)\n", p2_realloc, PTR_TAG(p2_realloc));
// Is p2_realloc the same address as p2 but different tag?
os_log(OS_LOG_DEFAULT, "Same address? %s\n",
((uintptr_t)p2 & 0x00FFFFFFFFFFFFFF) == ((uintptr_t)p2_realloc & 0x00FFFFFFFFFFFFFF)
? "YES" : "NO");
// Now try to use the OLD pointer p2
os_log(OS_LOG_DEFAULT, "Attempting use-after-free via old pointer p2...\n");
volatile char c = *(volatile char *)p2; // Should this crash?
os_log(OS_LOG_DEFAULT, "Read succeeded! Value: %d\n", c);
Example output:
p1 = 0xf00000b71019660 (tag: 15)
p2 = 0x200000b711958c0 (tag: 2)
p3 = 0x300000b711958e0 (tag: 3)
p2 after free+malloc = 0x700000b71019680 (tag: 7)
Same address? NO
Attempting use-after-free via old pointer p2...
Read succeeded! Value: -55

What do I need to do to make Memory Integrity Enforcement do something outside the debugger?
Hello everyone,
My app has been in “Waiting for Review” status since February 4, 2026, and there has been no progress or update since then.
Normally, my previous submissions were reviewed within a few days, but this time it has been significantly delayed. There are no messages in the Resolution Center, and I have not received any communication from the App Review team.
Has anyone else experienced similar delays recently?
Is there anything I can do to follow up or escalate this review?
Any guidance would be greatly appreciated.
Thank you.

I'm building an app which runs around the Foundation model framework. My expected output is generated when testing on a real device or in preview in Xcode but it throws Foundation Model error when I try running it on the simulator. I'm using a Macbook M1 air and have apple intelligence turned on and my simulator run destination is also an iPad Pro M5 (26.0).
Any solution for this as this is my submission for the SSC so I need to make it work on the simulator iPad.
Thank you👾

Apple is encouraging VPN apps on macOS to transition to Network Extension APIs, if they haven't done so yet, see:
TN3165: Packet Filter is not API
WWDC25: Filter and tunnel network traffic with NetworkExtension
Using Network Extension is fine for VPN apps that are distributed via the Mac App Store. Users get one pop-up requesting permission to add VPN configurations and that's it.
However, VPN apps that are distributed outside of the App Store (using Developer ID) cannot use Network Extension in the same way, such apps need to install a System Extension first (see TN3134: Network Extension provider deployment).
Installing a System Extension is a very poor user experience. There is a pop-up informing about a system extension, which the user has to manually enable. The main button is "OK", which only dismisses the pop-up and in such case there is little chance that the user will be able to find the correct place to enable the extension. The other button in that pop-up navigates to the correct screen in System Settings, where the user has to enable a toggle. Then there is a password prompt. Then the user has to close the System Settings and return to the app.
This whole dance is not necessary for VPN apps on the Mac App Store, because they work with "app extensions" rather than "system extensions".
As a developer of a VPN app that is distributed outside of the App Store, my options are:
Implement VPN functionality in an alternative way, without Network Extension. This is discouraged by Apple.
Use a System Extension with Network Extension. This is going to discourage my users.
I have submitted feedback to Apple: FB19631390.
But I wonder, why did Apple create this difference in the first place? Is there a chance that they will either improve the System Extension installation process or even allow "app extensions" outside of the Mac App Store?

The process has been stuck "In Progress" for 8 days now. We had a scheduled New Year Offer for our software that would run based around this important new update, and obviously we missed it because of this crazy issue. Notarization used to take a few seconds. Now it does not work, neither on my newly set up Mac, nor in my old (completely unchanged) one.
My company and finances are totally frozen at this point due to this issue. PLEASE help, look into my actual account and do what is needed!

Hi there,
We've discovered a problem with our iOS app. We've been attempting to add a Driverkit driver to it, but any time we run the app through Testflight, the driver installs fine, but when we go to enable the driver toggle in the app's settings, the toggle stays on, but in the device logs I can see:
could not insert bundle at <private> into manager: <private>
As you would expect - this means the driver is not actually enabled and does not respond to a device being connected to the iPad.
This does not happen when building & running the app locally, nor does it happen when installing an Ad Hoc build.
We also have a different app, not yet shipped. We are able to add the driver to that app without issue. It works after going through Testflight.
What we have discovered now is that everything works fine even if we just create an entirely new app with it's own bundle IDs. I should point out that in all cases, we're keeping the capabilities the same for each of these apps/IDs - including the managed capabilities.
The bundle IDs that have this problem are older (5 years old or more). It seems like any newer ID will work, but trying to add the driver (and the associated managed capabilities) to an older app/ID results in this vague error message, with no further details.
If we inspect the resulting dexts, we can also see that the "Internal requirements code size" is different on the ones that fail. The failing ones have a size of 204 bytes, whereas the working ones all have a size of 220 bytes. Not sure if that's related but it's strikingly consistent.
Does this mean there is an issue with older app IDs, and we need Apple to manually refresh them in some way before the driverkit capabilities will work after going through Testflight? We have two apps in this state, both are of the same vintage (~5 years+).
We've been battling this issue for months on and off, so would appreciate some help.
Hello,
I’ve been experiencing a persistent issue in Xcode since version 26.0, and it is still present in 26.2. When using the split view to display two files side by side, the area in the top‑right corner of the window (the inspector / options panel) starts flickering continuously.
This happens regardless of whether I’m using the light or dark theme, and even with the Liquid Glass effect disabled in macOS settings. None of these changes have any impact on the issue.
I have already submitted a bug report through Xcode (Feedback Assistant), but the issue is still present as of today.
The flickering makes the interface difficult to use and visually very distracting.
I’ve attached a video to clearly show the issue. I will review the attachment at the time I publish this post.
Thanks in advance for any help or feedback.

Has anyone else experienced extremely long wait times for app review or know what I can do to help expedite this process? I am waiting 22 days currently
I have done everything I have seen to do both sending an email and calling Apple support for help to have nothing changed or even a confirmation email of my call sent.
Does anyone have any advice?
I have a UIHostingController on which I have set:
hostingController.sizingOptions = [.intrinsicContentSize]
The size of my SwiftUI content changes with animation (I update a @Published property on an ObservableObject inside a withAnimation block). However, I notice that my hostingController.view just jumps to the new frame without animating the change.
Question: how can I animate the frame changes in UIHostingController that are caused by sizingOptions = [.intrinsicContentSize]
Hello,
After upgrading to macOS 26.2, I’ve noticed a significant performance regression when calling evaluateJavaScript in an iOS App running on Mac (WKWebView, Swift project).
Observed behavior
On macOS 26.2, the callback of evaluateJavaScript takes around 3 seconds to return.
This happens not only for:
evaluateJavaScript("navigator.userAgent")
but also for simple or even empty scripts, for example:
evaluateJavaScript("")
On previous macOS versions, the same calls typically returned in ~200 ms.
Additional testing
I created a new, empty Objective-C project with a WKWebView and tested the same evaluateJavaScript calls.
In the Objective-C project, the callback still returns in ~200 ms, even on macOS 26.2.
Question
Is this a known issue or regression related to:
iOS Apps on Mac,
Swift + WKWebView, or
behavioral changes in evaluateJavaScript on macOS 26.2?
Any information about known issues, internal changes, or recommended workarounds would be greatly appreciated.
Thank you.
Test Code Swift
class ViewController: UIViewController {
private var tmpWebView: WKWebView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
setupUserAgent()
}
func setupUserAgent() {
let t1 = CACurrentMediaTime()
tmpWebView = WKWebView(frame: .zero)
tmpWebView?.isInspectable = true
tmpWebView?.evaluateJavaScript("navigator.userAgent") { [weak self] result, error in
let t2 = CACurrentMediaTime()
print("[getUserAgent] \(t2 - t1)s")
self?.tmpWebView = nil
}
}
}
Test Code Objective-C
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions {
NSTimeInterval startTime = [[NSDate date] timeIntervalSince1970];
WKWebView *webView = [[WKWebView alloc] init];
dispatch_async(dispatch_get_main_queue(), ^{
[webView evaluateJavaScript:@"navigator.userAgent" completionHandler:^(id result, NSError *error) {
NSTimeInterval endTime = [[NSDate date] timeIntervalSince1970];
NSLog(@"[getUserAgent]: %.2f s", (endTime - startTime));
}];
});
}
Currently in our app, to identify a network switch in device we are doing NEHotspotHelper.register and then NEHotspotHelperHandler block. When the command type is evaluate and if the network.didJustJoin, we are identifying it as a network switch.
As a part of moving our code base to iOS 26, if is found that NEHotspotHelper is deprecated. What is the proper replacement for this?

I enrolled in the Apple Developer Program on February 3, 2026. The payment was completed successfully at the time of enrollment, but my membership status has remained “Pending” since then.
So far:
No request for additional documents or identity verification
No phone call from Apple
No follow-up email other than the payment confirmation
Apple Developer Support has been contacted, but no response yet
I understand that verification can take some time, but the complete lack of communication is concerning, especially since this is blocking active development and release planning.
If this is a known backlog or system-wide delay, some transparency from Apple would help. I’d also appreciate hearing whether others who enrolled in early February are seeing the same prolonged “Pending” state.
Thanks in advance to anyone who can share recent experiences or escalation paths.
Our team is in the process of updating our apps to comply with Texas's new state law.
In order to minimize user confusion and provide the most ideal flow to access the app as possible, we have a few questions we would like answered.
Summary of questions:
Is isEligibleForAgeFeatures intended to be accurate and accessible before the user has accepted the Age Range permissions prompt?
As other US states and/or other countries adopt a similar law going forward, will this instance variable cover those locations?
Will the runtime crashes on isEligibleForAgeFeatures and other symbols in the DeclaredAgeRange framework be addressed in a future RC or in the official release?
Details and Investigations:
With regards to isEligibleForAgeFeatures, our team has noticed that this value is always false before the age range prompt has been accepted. This has been tested on the XCode RC 26.2 (17C48).
Assuming the request needs to be accepted first,
isEligibleForAgeFeatures does not get updated immediately when the user chooses to share their age range (updated to true, when our sandbox test account is a Texas resident). Only upon subsequent relaunches of the app does this return a value that reflects the sandbox user's location. Is isEligibleForAgeFeatures intended to be accurate and accessible before the user has accepted the Age Range permissions prompt?
This leads to our follow-up question to clarify whether isEligibleForAgeFeatures explicitly correlates to a user in an affected legal jurisdiction–if future US states and/or other countries adopt a similar law going forward, will this instance variable cover those locations?
Can we also get confirmation about whether the runtime crash on isEligibleForAgeFeatures and other symbols in the DeclaredAgeRange framework will be addressed in a future RC or in the official release?
Thank you.
My application installs a system extension.
When I try to remove the app from the Applications folder (cmd + backspace) I get an error message:
"The operation can’t be completed right now because another operation is in progress, such as moving or copying an item or emptying the Bin."
According to systemextensionsctl the extension state is "terminating for uninstall but still running".
I can see an error in the console logs:
kernelmanagerd Failed to terminate dext com.my.driver-dk, error: Kernel request failed: (os/kern) invalid address (1)
sysextd a category delegate declined to terminate extension with identifier: com.my.driver-dk
sysextd failed to terminate extension with identifier: com.my.driver-dk: Optional(Error Domain=kernelmanagerd.KMError Code=38 "(null)")
Issue occurs with macOS 13 - works fine with macOS 12 and macOS 11
What is the problem here?
Have there been any changes in macOS in that regard?
Hi guys,
I am new to the Apple Developer Program (enrolled a few days ago) and this is my first
app notarization attempt. I've been experiencing significant delays - all submissions
have been stuck at "In Progress" for over 24 hours.
Details:
macOS app signed with Developer ID Application certificate
Using xcrun notarytool with app-specific password
Hardened runtime enabled
codesign --verify --deep --strict passes
Team ID: QVHM976XC5
Submission IDs (all stuck "In Progress"):
5f494a89-0db0-4cc6-944f-ca2fe399e870 (latest - 8+ hours)

d0edcbfe-8464-455f-b077-bebaa5b9aab7
I understand new developers may experience longer initial processing, but 24+ hours
seems excessive. Is there anything I should check or any additional steps required
for new accounts?
Any guidance appreciated.

Dear Apple Customer Support,
I’m developing a new Swift iPadOS app and I want the app to run in landscape only (portrait disabled).
In Xcode, under Target > General > Deployment Info > Device Orientation, if I select only Landscape Left and Landscape Right, the app builds successfully, but during upload/validation I receive this message and the upload is blocked:
“Update the Info.plist: Support for all orientations will soon be required.”
Could you please advise what the correct/recommended way is to keep an iPad app locked to landscape only while complying with the current App Store upload requirements?
Is there a specific Info.plist configuration (e.g., UISupportedInterfaceOrientations~ipad) or another setting that should be used?
Thank you,
A macOS privileged helper tool that uses SubProcess crashes on intel Macs (running macOS 13 - 15: unable to test on macOS 26 on intel) with the error that libswiftCompatibilitySpan.dylib cannot be loaded when built with XCode 26.3. The same helper tool works as expected with XCode 26.2.
The helper is installed using SMAppService.
When I remove the dependency for SubProcess, the crash no longer occurs (but important functionality is also disabled).
We’re having an iPad issue accessing the local network with iPadOS 26.3. We have an automation system that tests our app on an iPad using accessibility tags. the XCTest test code sends messages from the iPad via TCP/IP to setup external test equipment. The messages abruptly stopped transmitting across the iPad blood-brain barrier with iPadOS 26.3 (26.2.1 and earlier works fine).
The technique that worked involved installing a helper app with the same bundleID as our app, allowing the helper app to access the network, and when our app runs it has network access through the helper. It’s clever and kludgey.
Forums that we referenced in the past:
https://developer.apple.com/forums/thread/663858
TN3179: Understanding local network privacy | Apple Developer Documentation
I suspect that something was changed in 26.3 that closed our window. I need two things: ID what is different in 26.3 and fix the automation system. If there’s a new way for XCUITest code to access the local network I’m happy to try it out.
In the WWDC 2019 session "Extended Runtime for WatchOS apps" the video talks about an entitlement being required to use the HR sensor judiciously in the background.
It provides a link to request the entitlement which no longer works: http://developer.apple.com/contect/request/health-monitoring
The session video is also quite hard to find these days.
Does anyone know why this is the case?
Is the API and entitlement still available?
Is there a supported way to run, even periodically, in the background on the Watch app (ignoring the background observer route which is known to be unreliable) and access existing HR sensor data
