Hello Folks,
I recently came through a new API introduced from iOS 18 onwards isSIMInserted and according to the document it is A Boolean property that indicates whether a SIM is present. I really appreciate Apple for introducing such an useful API but there are few queries on what are the requirements for using this API.
Query 1: Do we need any special entitlements for making use of this API. ? If yes then what are those entitlements and are these entitlements available openly or we have to raise special request to apple for such entitlements?
Query 2: What are the entries required to be added in info.plist for supporting the isSIMInserted api to work.
Query 3: Is isSIMInserted api available for all type of apps because mine is a financial stock related app and i am looking forward to use this API for providing more security to the end user while registering through sms. As per the below link this api is only available for mobile Carrier apps but in official document there is no such mention.
https://forums.developer.apple.com/forums/thread/760991
Please kindly help me on these queries ?
Regards,
Carol

I have universal links configured for my iOS app which work as expected when the app is installed. When the app is not installed the universal link will go to the browser as expected.
What I want to do is redirect to the app store, allow the user to install the app, then redirect them to the initial universal link. Redirecting them to the app store isn't the hard part I can achieve that from the webpage, however I don't know how to save a reference to that initial link to redirect them once they instal the app.
What I want the flow to be for a user who doesn't have the app is:
visit a universal link (example.com/UUID)
redirect to the app store and install the app
open the app and redirect to example.com/UUID
I've seen some ways people are doing this with the clipboard but I don't love that solution, I also don't want to use a 3rd party service if I can avoid it - how are the 3rd party services making this happen?
Since iOS 18.4 and macOS 15.4 updating the calendar of an (ek)event (to another accounts calendar) or detaching an repeating event throws an error while saving:
"Access denied"
EKEventStore.save(event, span: .thisEvent, commit: true)
catch {
"Access denied"
}
In a project having both an app and a website, the following two website urls are to be handed over to the corresponding app:
https://www.example.com/search?plus https://www.example.com/search?query=something
In AASA file, this becomes:
"components": [ { "/": "/search", "?": { "plus": "", "query": "?*" } }
However, finally it does not work for both urls. Only the one with "query" works by hand over to app.
For investigation, I have tried this for the problematic link:
"components": [ { "/": "/search", "?": "plus" }
and this works.
How can I get both to work?
(note that for the sake of brevity, only a portion of the AASA files are shown)
This is a bit of a headscratcher. Xcode 16 fyi.
I've written a standalone watchos app (with a stub ios app).
Distributes and works perfectly over Testflight.
I've submitted for app store and it passed the checks an I've released it for sale.
Told my brother to use a promo code to download it and show me how it looks and report me any nuisances.
He tells me there's no app neither on phone (expected) nor in watch. And he checked both the Watch ios app list and the watch.
I've gone through various GPTs and they've all told me the basic troubleshooting. That his watch might not be supported (wrong, it's a watch 10 ultra with latest updates and my min supported versions are hilariously low).
They've suggested that I might not have the right keys for making it standalone set, also no. They suggested that skip_install shouldn't be set to no; also wrong I think they're thinking xcode 13 and below. The stub ios app has a dependency on watchos app and also has an embed directive. I also checked the archive and saw the watchos app embedded indeed.
Again, the app works perfectly fine when distributed over testflight. And AFAIK that's a release build which I know for a fact because I had a problem with not giving healthkit entitlements to release (that was another but minor headscratcher at the time, when it was working over direct xcode upload).
Minor detail, I've written, test(flight)ed the app in UK and in English, my brother is in Turkey.
Of course now I immediately pulled the app out of sale because I don't want people paying and getting nothing, that's gonna cause a lot of trouble.
So I need any help I can get to
How to debug this without exposing the app and myself: is it possible to limit the release?
Obviously: what could be going wrong?
How the hell did I even pass app review? Is this maybe isolated to my brother's watch?
I'm more than happy to share project files and/or info.plist files(end products of them, because my plists are generated from project file).
Hi All,
I am facing one problem in my app.
That is open battery settings from my app.
It is working fine in iOS 16.0.0 and it's not working in iOS 18.6.1
is it possible to make it workable in iOS 18.6.1?
If so How to do that?
Please help me over this to resolve the problem.
Thanks,

I am trying to send an anonymous XPC listener endpoint to my daemon from user context in order to be able to do some bidirectional XPC.
I was trying to use the new XPCListener and XPCSession objects and the easiest method I figured was using the Codable version of the send() methods, in which I wanted to send the XPCEndpoint object - alongside the name of the anonymous endpoint (because I want to have more XPCEndpoints sent over, so I want to be able to identify them.
However, trying to manually encode XPCEndpoint throws an exception:
ERROR: Missing CodingUserInfoKey CodingUserInfoKey(rawValue: "_XPCCodable")
Here is a simple command-line tool reproducing the issue:
import Foundation
import XPC
let listener = try XPCListener(service: "mach-service.xxx.yyy", incomingSessionHandler: {
$0.accept(incomingMessageHandler: { (msg: XPCReceivedMessage) in
return nil
})
})
var endpoint = listener.endpoint
do {
let endpointData = try JSONEncoder().encode(endpoint)
print("EndpointData object: \(endpointData.count) bytes")
} catch let error {
print("ERROR: \(error)")
}
Wrapping my object into an XPCDictionary, then adding multiple keys alongside an "endpoint" key with the XPCEndpoint as value works, but XPCDictionaries are less ideal - they don't even support vanilla Data objects, only ones converted to an xpc_object_t with xpc_data_* functions
Is this expected behavior? I shouldn't encode an XPCEndpoint myself? I am using the latest Xcode 26.0 beta, with deployment target of macOS 15.1, running on macOS 15.5.
(Btw it's also incorrect that this XPCEndpoint API is available from macOS 15.0 - it cannot be found in Xcode 15.4 under macOS 15.5. At the very best it's backDeployed but this isn't mentioned in its public declaration.)
Hello,
I've been encountering some challenges while working with NWConnectionGroup and NWMulticastGroup for multicast operations on iOS. I have a few doubts and issues that I would like to address:
1. NWMulticastGroup Initialization
It seems that when initializing NWMulticastGroup, only one NWEndpoint can be passed, and attempting to pass multiple endpoints results in failure. Can someone confirm if this behavior is correct?
2. Interface Level Control
Upon initializing NWConnectionGroup, it appears that packets are received on all interfaces without the ability to control this at the interface level. Is this correct? If not is there a way to configure NWConnectionGroup to receive packets on all interfaces?
3. Sending Behavior
During the send operation, it appears that the data is sent through any one of the available interfaces, and there doesn't seem to be an option to configure it to send through all available endpoints. Is there a way to enable sending data through all available endpoints?
Any insights, guidance, or solutions to these issues would be greatly appreciated. Has anyone else encountered similar problems or found workarounds for these limitations?
Thank you for your assistance and support.
Thanks,
Harshal
Dear,
I am starting to read the documentation about HCE payments and doing the first tests in my device. I have noticed that the only way to request contactless payment permissions is calling:
NFCPresentmentIntentAssertion.acquire()
And if it is the first time will prompt a popup asking the permissions and if not and the user denied the permission will throw the error systemEligibilityFailed.
My doubt is, is there other way to ask the contactless permissions instead of using the acquire? Because I understand that the acquire method is mainly created to prevent the default contactless app from launching. So I assume that it is not a good practice to use some point in the app just for asking the permission, right? Or for the first time we can use it for that purpose?
According to that, is there any way to get the current contactless payment permissions status, just as we can get it from the camera (AVCaptureDevice.authorizationStatus(for: mediaType: AVMediaType))?
The main goal is to give to the user a good experience. First asking the permission in a specific screen that explain why we need this permission and if the user denies it show some information in a screen as we can do it with other services as camera, micro, location...
Thank you
Using Apple SwiftUI Translate library: when calling:
try await session.prepareTranslation()
the first time, the API's Language Download sheet does not show (or shows briefly and dismisses immediately) Even when the sheet doesn't show, the keyboard is lowered, as though the sheet would be appearing, but then the keyboard raises as though the sheet was dismissed.
The following Errors are printed in the console dozens of times; but on all subsequent executions, the API Language Download sheet shows as expected.
The trigger code is in a function which is executed when a Translate button is tapped.
Any ideas would be welcome!

We have found a large number of memory-related crashes in iOS18, and multiple issues have finally pointed to this crash line xzm_xzone_malloc_tiny_outlined. Do not know how to solve it now
On iOS 18 and lower version, my application supports automatically switching to [System settings - Personal Hotspot] directly. But on iOS 26, my application will be redirected to [System settings- Apps].
Does iOS 26 disable the behavior of directly jumping to the system hotspot page? If support, could you share the API for iOS 26?
I have also tested this on iOS 26 (Beta 9 and above), and the CallKit call blocking functionality is not working. Numbers that should be blocked still ring through. Caller Identification continues to function as expected, but blocking entries (addBlockingEntry) are ignored.
My iOS app uses a Message Filter extension (via ILMessageFilterQueryHandling) and works only when run directly as the extension target. When installed normally (via TestFlight), the filter does not trigger at all — which I now believe is because iOS enforces the com.apple.developer.identitylookup entitlement at runtime.
Anyone know anything about this? I put in a request for the entitlement last week but heard nothing back. Called Apple "technical" support and they had no idea what I was talking about.
The documentation around this is EXTREMELY lacking in my opinion...
Hello,
After being in the AppStore for more than a year with the app working perfectly, yesterday I started seeing that WeatherKit requests failed with
Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
Encountered an error when fetching weather data subset; location=<+41.40217108,+2.20023642> +/- 0.00m (speed -1.00 mps / course -1.00) @ 13/12/25, 12:20:35 Central European Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"
I checked on developer.apple.com and we still have everything turned on and
No changes were made from an already deployed app; and we pay 200$ a month for WeatherKit, this is unacceptable since it's not the first time WeatherKit randomly decides to stop working.
More fun facts: the widget works fine...
Our users report frequent crashes with the FamilyActivityPicker. Since this is a screen controlled by Apple, I'm assuming that there's nothing I can do to prevent these crashes.
I'm wondering, though, if there's any way to gracefully handle these crashes? When this happens, the following is printed to the console:
[com.apple.FamilyControls.ActivityPickerExtension(1121)] Connection to plugin invalidated while in use.
Does anyone know how to handle/catch this error?
Hello!
I’m trying to handle custom URLs (e.g., customurl://open?param=value) that open the app. However, while the app launches via the custom URL as expected, the parameters are not being passed to or are accessible from the iOS-specific implementation.
Currently, if I open a custom URL via Safari, the app gets launched but the custom URL and parameters are not accessible.
customurl://open?hello=test
According to the iOS Docs ( https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Handle-incoming-URLs )
any URLs should be passed to:
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:] ) -> Bool
I do not register the above application function to be called but instead this one is executed during app start with launchOptions always being nil:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool
This is the case regardless of if the App is started fresh or was already running in the background.
My pInfo entry for the custom URL:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleTypeRole</key>
<string>Viewer</string>
<key>CFBundleURLName</key>
<string>dev.customurl.project</string>
<key>CFBundleURLSchemes</key>
<array>
<string>customurl</string>
</array>
</dict>
<dict/>
</array>
TLDR: How can I access the parameters, passed with the URL?
Any thoughts on what I am doing wrong?
The universal links for my apps stopped working.
The server where the AASA files where hosted worked on IPV4 exclusively, a few days ago i changed the configuration to IPV6 only. I´ve created new IPV6 entries, renewed all certifactes and deleted all IPV4 entries for the domains.
All seemed fine, but at Saturday I realized that my universal links stopped working for new user.
What i´ve done to find the issue:
Example domain that was used for debugging: "https://developffw.burns.fun"
I´ve verified the AASA file is hosted properly by using different browsers and Postman to retrieve it. The file can be accessed and the certificates look fine.

I took a look at the headers from the Apple CDN network response. These indicate some sort of connection error.

Took a look at the log files of the server.
I can´t find any entry from the Apple servers neither in the default logs nor in the error log entries.
The curl attempts are logged with response code 200.
I´ve tried sudo swcutil dl -d https://developffw.burns.fun/onboard in the Terminal on my MAC.
Output:
The operation couldn´t be completed. (SWCErrorDomain error 8.)
This indicates to me threre is an issue for the Apple servers accessing my server. But I don´t know what could be the reason. There is no firewall configuration that could block the requests. And there has been no change at all besides the IPV4 / IPV6 protocol change.
This issue is the same for all the domain listed on this server.
I´v even created a new app for this purpose and created a new AASA entry and associated link. Same issue.
I´m pretty much lost here. Everything looks fine from my side. Google assetlinks.json seem to work fine.
I would really appreciate some help on how to solve this, i´m at my wits end.
I’m currently developing a spam number blocking app using CallKit.
I’ve confirmed that up to iOS 26 beta 5, there is a bug where number blocking doesn’t work.
In my current tests, the ringtone doesn’t sound and the blocking works fine, but the call still appears in the missed calls list, which is bothersome.
If the bug is fixed in future versions (as it was in previous versions), is there a way to block the number so that it also does not appear in missed calls?
I have a home widget with buttons (new in iOS 17).
In order to prevent taking action if the user taps on the widget buttons accidentally, I want to ask the user for confirmation.
It appeared that requestConfirmation be exactly what I needed, but no confirmation view shows up when I invoke this method in the perform function.
I have tried the following:
try await requestConfirmation(result: .result(dialog: "Are you sure you want to do this?") {
Image(.mdlsWhite)
})
and this alternative:
let confirmed: Bool = try await $name.requestConfirmation(for: self.name,
dialog: IntentDialog(stringLiteral: msg))
Neither option work.
I am starting to think that the requestConfirmation is not to be used with Home Widgets.
Is there a better way to handle confirmations for buttons included in a Home Widget?
