Is there a way to distinguish physical mouse/keyboard input from remote control mouse/keyboard input on Mac? Or even better, is there a way to detect if my Mac is being remotely controlled?
I'm currently developing an app with mapkit which I may submit to the Swift Student Challenge. So anyways, the app will be used completely offline. I was wondering if there was any way to include very low resolution map tiles with the app files. That way, the app never needs wifi. However, I'm not sure if this is possible, especially since the map would need to be under 20 mb. Thanks.

Can be reproduced with a shared iPad setup (https://support.apple.com/de-de/guide/deployment/dep9a34c2ba2/web) and the example app provided by Apple (https://developer.apple.com/documentation/fileprovider/synchronizing-files-using-file-provider-extensions).
The issue is that when using the File Provider extension implemented with 'NSFileProviderReplicatedExtension', the content of the share does not display in the iPadOS Files app. The 'NSFileProviderEnumerating.enumerator' function is invoked, but none of the functions of the returned 'NSFileProviderEnumerator' are executed: neither 'currentSyncAnchor', 'enumerateChanges', nor 'enumerateItems'. Instead, the 'NSFileProviderEnumerator' is immediately invalidated. This issue can be reproduced with iPadOS 18.3 and a shared iPad setup.
Maybe i missing some additional steps/ settings in my extension to work properly on Shared iPads.
Created also a post on the feedbackassistent: FB16587660 (NSFileProviderReplicatedExtension does not work in Shared iPad setup)
Steps to reproduce:
iPad with a Shared iPad profile
Enroll the iPad and log in as a Guest user
Turn on developer mode
Install the example app from Apple (as mentioned above)
Add some test files to the FruitBasket storage
Add this FruitBasket domain to the FruitBasket-iOS app
You may need to provide "Privacy - Local Network Usage Description" in the Info.plist of the FruitBasket-iOS example app to be able to find local FruitBasket storage.
Check in the Files app to see that the FruitBasket share is empty
-> The expected behavior is that the FruitBasket share should contain the test files added previously. (This works fine without a shared iPad setup).
Hi, all!
I have an AppStore Server-side question. User sends up an AppReceipt that I am validating. What's the best way to tell the receipt belongs to said user? I want to make sure that the source of the AppReceipt was actually the original purchaser of the item. Is fetching Transaction + AppAccountToken the only way? AppAccountToken can only be utilized if the original purchase used it, and it is associated with the user's data. Is there another way?
The crash stack is as follows, and this crash only occurs on this model.
My MacOS swift app [myStuckApp5] refuses to close when running on Monterrey (The app becomes unresponsive after finishing its work, and needs to be forcefully closed). However, it closes as expected when running MacOS 13 and above. How can I troubleshoot this error?
I'm attaching the content of the sys Log related to the app while it was stuck (too long to copy here...)

Hi,
I’m trying to get an array of strings from the user using AppIntents, but I’m encountering an issue. The shortcut ends without prompting the user for input or saving the value, though it doesn’t crash. I need to get the user to input multiple tasks in an array, but the current approach isn’t working as expected.
Here’s the current method I’m using:
// Short code snippet showing the current method
private func collectTasks() async throws -> [String] {
var collectedTasks: [String] = tasks ?? []
while true {
if !collectedTasks.isEmpty {
let addMore = try await $input.requestConfirmation("Would you like to add another task?")
if !addMore {
break
}
}
let newTask = try await $input.requestValue("Please enter a task:")
collectedTasks.append(newTask)
}
return collectedTasks
}
The Call
func perform() async throws -> some IntentResult {
let finalTasks = try await collectTasks()
// Some more Code
}
Any advice or suggestions would be appreciated. Thanks in advance!
In the main app, is there a way to distinguish whether the application:didFinishLaunchingWithOptions: method is triggered by the user manually clicking the app icon, or whether it is automatically triggered by the system after Live Activities receives a remote message notification?
Hi team at Apple, here is a scenario we came across:
The order of priority of payment methods in Apple Wallet follows:
Credit
Debit
Apple Cash
Our app displays a payment sheet that excludes credit cards. Instead of a debit card, the default payment option shown to the user on the payment sheet is Apple Cash.
Is this a known issue or have we configured something wrong in our end?
Is there any way to use AccessorySetupKit in the background to discover BLE devices?
Hi everyone,
I’m facing a recurring issue with my macOS app being rejected during App Store review, and I’d really appreciate any guidance.
The subscription flow in my app is implemented using StoreKit, and everything works perfectly in our development environment using a StoreKit configuration file. It also behaves as expected in Sandbox testing and TestFlight — I even had few beta testers confirm that the subscription information is displayed correctly and the purchase flow completes without issues.
All required subscription details are configured in App Store Connect:
• Subscription duration and the description of the services offered
• Price and price per unit where applicable
• Paid apps agreement and related forms are correctly filled
However, when the app is submitted for review, the subscription screen fails to display the expected information. From what I can tell, the product information fails to load from the App Store in the review environment — even though everything is working fine on our side.
We’ve already submitted a video to Apple showing the subscription UI working in the Sandbox environment, but the app continues to be rejected under guideline 3.1.2 due to missing subscription info in the binary.
Is anyone else experiencing similar behavior during review? Could there be a caching issue or delay in StoreKit syncing for newly configured products?
Any help or suggestions are very welcome. Thanks in advance!

Hello,
We are currently implementing iOS order verification and have encountered an issue. Some of the receipts we verify return with an empty in_app array, which makes it impossible to determine whether there is a valid in-app purchase.
Below is the code we’re using for verification and the result we receive:
Code Example:
public function iosVerifyReceipt($receipt, $password = '', $sandbox = false)
{
$url = $sandbox ? 'https://sandbox.itunes.apple.com/verifyReceipt' : 'https://buy.itunes.apple.com/verifyReceipt';
if (empty($password)) {
$data = json_encode(['receipt-data' => $receipt]);
} else {
$data = json_encode(['receipt-data' => $receipt, 'password' => $password]);
}
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result, true);
$result = $result ?? [];
$result['sandbox'] = $sandbox;
if ($result['status'] != 0) {
Log::warning('ios verify receipt failed', ['receipt' => $receipt, 'result' => $result, 'sandbox' => $sandbox]);
if ($result['status'] == 21007) {
return $this->iosVerifyReceipt($receipt, $password, true);
}
}
return $result;
}
// Order validation check
if (empty($result) || $result['status'] != 0) {
throw new BadRequestHttpException("Ios Order Verify Error");
}
$appItemId = $result['receipt']['app_item_id'] ?? "";
if ($appItemId != MY_APP_ID) {
throw new BadRequestHttpException("Ios Order Verify Error");
}
$inApp = array_filter($result['receipt']['in_app'] ?? [], function ($item) use ($transactionId, $order) {
return $item['transaction_id'] == $transactionId && $item['product_id'] == $order->getProductId();
});
if (empty($inApp)) {
throw new BadRequestHttpException("Ios Order Verify Error");
}

Problem Description:
• We are noticing that in some orders, the in_app array is returned as empty. This causes difficulty in verifying the presence of in-app purchases.
• Our validation logic assumes that if in_app is empty, the order is invalid, but we would like clarification on whether this is correct or if such a scenario is normal under certain conditions.
Actions Taken:
• We have reviewed Apple’s documentation and other related resources, but no clear explanation is given about when in_app might be empty.
• Can we safely rely on an empty in_app array to consider the order invalid, or should we investigate further for potential issues like delays or errors during the verification process?
We would appreciate your guidance on how to handle such cases. Thank you for your support!
I get crash reports which I can't reproduce when trying to present an SKStoreProductViewController :
Fatal Exception: UIApplicationInvalidInterfaceOrientation
Supported orientations has no common orientation with the application, and [SKStoreProductViewController shouldAutorotate] is returning YES
No matter what app Deployment info orientation I try I can't get my SKStoreProductViewController shouldAutorotate property to return YES. It is always false.
Does anyone knows why or how to get an SKStoreProductViewController to return shouldAutorotate YES?

Hi there, I'm facing an issue when disconnecting CarPlay that the navigation session seems to be in some weird state where it is not properly finished. So when I reconnect CarPlay the "Metadata in instrument cluster or HUD" does not update anymore until I start another navigation session and stop that one.
You can see that the instruction to the left on this screen recording is not updating anymore after a reconnect.
https://www.youtube.com/watch?v=sncxyJULjQk
I have a modified the CostalRoad sample app to add support for the HUD cluster and to auto start a navigation simulation when CarPlay connects.
https://github.com/g4rb4g3/CoastalRoads
Can anyone tell me what I have to do when CarPlay disconnect so I can start a new navigation session on reconnect that has a working HUD cluster?
Fun fact is that Apple Maps handles this quite nice (https://www.youtube.com/watch?v=OpJEIyGcwdo), it somehow manages to finish the navigation session and brings up the HUD cluster just fine on reconnect.
I wonder how I can achieve the same, anyone having an idea on that?
We are experiencing an Unknown Error (error code 0) when testing purchases in the Apple Sandbox environment.
The error does not occur every time, but it fails with an Unknown Error in approximately 8 out of 20 attempts.
Due to this issue, our app is failing to pass Apple’s review.
Issue Details
This issue only occurs in the Apple Sandbox environment.
After attempting a purchase, the Apple payment API returns SKPaymentTransaction Unknown Error.
Returned error code: SKErrorUnknown (error.code 0).
This problem is preventing us from conducting proper payment tests and getting approval from Apple.
Would it be possible to receive support or any solutions for this issue?
I have implemented the functionality to open my app when double-tapping the side button on an iPhone. However, whenever I double-tap the side button, my app always opens on the login screen. Instead of this default behavior, I want my app to navigate directly to a specific view when launched through the side button action.
I am using SwiftUI and have already integrated HCE (Host Card Emulation) entitlements and also configured with contactless payment. How can I achieve this behaviour so that my app opens a specific screen instead of always showing the login page?
Any guidance on handling this within SwiftUI would be greatly appreciated. Thank you!

Hi all,
From what I’ve seen on forums and other sources, it appears that nothing can be done to set the contact poster programmatically. Setting the imageData property affects only the thumbnail image. Does anyone know if this is explicitly documented somewhere? I need this information for a POC document. I watched the iOS 17 keynote (where it was introduced), the Platform State of Union, and other WWDC videos, but I couldn’t find any mention of it. The Contacts framework documentation only explains what can be retrieved from this property and doesn’t mention any way to set the contact poster.
If anyone has any information on this, please help!
Thanks in advance!
Hello,
I am developing a calling service using CallKit and VOIP push.
I have occasionally encountered a strange issue.
The issue is that VOIP permanently fails to receive calls.
I was previously informed that even if the device is blocked, it can receive calls again after 24 hours.
Also, when I checked the device logic, it complied with the policy requirements set by Apple, including correctly calling CallKit's reportNewIncomingCall method.
Once the issue occurs, no matter how many times I try, VOIP does not receive calls, and neither a device reboot nor checking the Device Console Log shows any logs related to CallKit or VOIP.
I suspect this might be an issue with the VOIP token, and I believe that the only way to get a new one is to reinstall the app. Is that correct?
Of course, after reinstalling, it works fine again, but this is very inconvenient. I don't think this is the right solution.
Is there anyone who can share their insights on this issue?
Thank you.
Hey there my application allows users to have video calls with each other using Agora. I have successfully set up incoming call functionality on Android but on iOS I am struggling to get the call ui to appear when the app is not running/in background/locked.
To my knowledge this is because there is much stricter security on iOS which is limiting me from calling this. When i initially set it up it worked at first when the app was in the background but I think I was failing to report the call to call kit in time and now it's not working.
I'm not sure if I need access to this entitlement:
com.apple.developer.pushkit.unrestricted-voip
Which i believe is only for the big boys or if I make sure I'm reporting the call to call kit fast enough that I won't encounter this issue and it will consistently work in the background.
Hi,
I'm working on a game for the past few years using first Unreal Engine 4, and now Unreal Engine 5.4.4.
I'm experiencingan unusual crash on startup on some devices
. The crash is so fast that I'm barely able to see the launching screen sometimes because the app closes itself before that.
I got a EXC_CRASH (SIGABRT) so I know that it's a null pointer reference, but I can't quite wrap my head about the cause, I think that's something messed up in the packaging of the app, but here is where I'm blocked, I'm not that accustomed with apple devices.
If someone has some advise to give, please, any help will be very valuable. Many thanks.
