User Initiated a Single Consumable Purchase but Was Charged Twice
A user initiated a single in-app purchase for a consumable item, but they were charged twice. Both transactions have the same purchase token.
Additional details: After the user successfully completed the in-app purchase, the completeTransactions callback was triggered again. This was called at app launch using SwiftyStoreKit.completeTransactions to finish any pending transactions.
Could this be causing the duplicate charge? Any insights would be appreciated.

DESCRIPTION
I have an App use iCloud to save data.
The App had a CoreData ManagedObject 'Product', 'Product' Object had an attribute name 'count' and it is a Double Type.
I need to synchronises 'count' property across multiple devices.
for example:
I have a devices A、B.
A device set 'Product.count' = 100.
B device set 'Product.count' = 50.
I hope the 'Product.count' == 150 that results.
how to synchronises the 'Product.count' == 150 for multiple devices.
If I have more devices in future, How to get the latest 'Product.count' that it is correct result.
Hi everyone,
I'm experiencing an issue with APNs server notifications where I receive a 404 error when trying to validate the signedPayload from Apple's notification. Below is a sanitized version of my code:
class ServerNotificationAppleController extends Controller
{
// URL for StoreKit keys (Sandbox environment)
private $storeKitKeysUrl = 'https://api.storekit-sandbox.itunes.apple.com/inApps/v1/keys';
public function handleNotification(Request $request)
{
\Log::info($request);
$signedPayload = $request->input('signedPayload');
if (!$signedPayload) {
return response()->json(['error' => 'signedPayload not provided'], 400);
}
// Step 1: Create your JWT token (token creation logic can be in a separate service)
$jwtToken = $this->generateAppleJWT();
// Step 2: Send a request to the StoreKit keys endpoint
$response = Http::withHeaders([
'Authorization' => 'Bearer ' . $jwtToken,
])->get($this->storeKitKeysUrl);
Log::info('Apple Keys Status:', ['status' => $response->status()]);
Log::info('Apple Keys Body:', ['body' => $response->body()]);
if ($response->status() !== 200) {
return response()->json(['error' => "Apple public keys couldn't be retrieved"], 401);
}
$keysData = $response->json();
// Step 3: Validate the signedPayload
$validatedPayload = $this->validateSignedPayload($signedPayload, $keysData);
if (!$validatedPayload) {
return response()->json(['error' => 'Invalid signedPayload'], 400);
}
// Process the validated data as needed
Log::info("Apple Purchase Data:", (array)$validatedPayload);
return response()->json(['message' => 'Notification processed successfully'], 200);
}
private function generateAppleJWT()
{
// API key details (replace placeholders with actual values)
$keyId = config('services.apple.key_id'); // e.g., <YOUR_KEY_ID>
$issuerId = config('services.apple.issuer_id'); // e.g., <YOUR_ISSUER_ID>
$privateKey = file_get_contents(storage_path(config('services.apple.private_key')));
// Set current UTC time and expiration time (20 minutes later)
$nowUtc = Carbon::now('UTC');
$expirationUtc = $nowUtc->copy()->addMinutes(20);
// Create the payload with UTC timestamps
$payload = [
'iss' => $issuerId,
'iat' => $nowUtc->timestamp,
'exp' => $expirationUtc->timestamp,
'aud' => 'appstoreconnect-v1',
'bid' => 'com.example.app', // Replace with your Bundle ID if necessary
];
// Generate the JWT token
return JWT::encode($payload, $privateKey, 'ES256', $keyId);
}
private function validateSignedPayload($signedPayload, $keysData)
{
try {
$jwkKeys = JWK::parseKeySet($keysData);
return JWT::decode($signedPayload, $jwkKeys, ['RS256']);
} catch (\Exception $e) {
Log::error("Apple Purchase Validation Error: " . $e->getMessage());
return null;
}
}
}
I’m particularly puzzled by the fact that I receive a 404 error when trying to retrieve the public keys from the StoreKit keys endpoint. Has anyone encountered this issue or can provide insight into what might be causing the error?
Any help or suggestions would be greatly appreciated. Thanks!
Hello! We're currently testing Live Caller ID implementation and noticed an issue with userIdentifier values in our database.
Initially, we expected to have approximately 100 records (one per user), but the database grew to about 10,000 evaluationKey entries. Upon investigation, we discovered that the userIdentifier (extracted from "User-Identifier" header) for the same device remains constant throughout a day but changes after a few days.
We store these evaluation keys using a composite key pattern "userIdentifier/configHash". All these entries have the same configHash but different userIdentifier values.
This behavior leads to unnecessary database growth as new entries are created for the same users with different userIdentifier values.
Could you please clarify:
Is this the expected behavior for userIdentifier to change over time?
If yes, is there a specific TTL (time-to-live) for userIdentifier?
If this is not intended, could this be a potential iOS bug?
This information would help us optimize our database storage and implement proper cleanup procedures.
Thank you for your assistance!
i thought it is impossible to have CallKit show system UI for outgoing calls. but then i saw this:
"For incoming and outgoing calls, CallKit displays the same interfaces as the Phone app..."
https://developer.apple.com/documentation/callkit
how do i present it though? or is this a documentation error?
Hi,
I have developed an app which has two in-app purchase subscriptions. During the test, the app can successfully get the status of the subscriptions. After it's released, I downloaded it from app store and subscribed it with my apple account. I found that in most cases, the app can identify that I have subscribed it and I can use its all functions. But yesterday, when I launched it again, it showed the warning that I haven't subscribed it. I checked my subscription in my account and the subscription status hasn't been changed, that is, I have subscribed it. And after one hour, I launched it again. This time the app identified that I have subscribed it. Why? The following is the code about listening to the subscription status. Is there any wrong about it?
HomeView()
.onAppear(){
Task {
await getSubscriptionStatus()
}
}
func getSubscriptionStatus() async {
var storeProducts = [Product]()
do {
let productIds = ["6740017137","6740017138"]
storeProducts = try await Product.products(for: productIds)
} catch {
print("Failed product request: \(error)")
}
guard let subscription1 = storeProducts.first?.subscription else {
// Not a subscription
return
}
do {
let statuses = try await subscription1.status
for status in statuses {
let info = try checkVerified(status.renewalInfo)
switch status.state {
case .subscribed:
if info.willAutoRenew {
purchaseStatus1 = true
debugPrint("getSubscriptionStatus user subscription is active.")
} else {
purchaseStatus1 = false
debugPrint("getSubscriptionStatus user subscription is expiring.")
}
case .inBillingRetryPeriod:
debugPrint("getSubscriptionStatus user subscription is in billing retry period.")
purchaseStatus1 = false
case .inGracePeriod:
debugPrint("getSubscriptionStatus user subscription is in grace period.")
purchaseStatus1 = false
case .expired:
debugPrint("getSubscriptionStatus user subscription is expired.")
purchaseStatus1 = false
case .revoked:
debugPrint("getSubscriptionStatus user subscription was revoked.")
purchaseStatus1 = false
default:
fatalError("getSubscriptionStatus WARNING STATE NOT CONSIDERED.")
}
}
} catch {
// do nothing
}
guard let subscription2 = storeProducts.last?.subscription else {
// Not a subscription
return
}
do {
let statuses = try await subscription2.status
for status in statuses {
let info = try checkVerified(status.renewalInfo)
switch status.state {
case .subscribed:
if info.willAutoRenew {
purchaseStatus2 = true
debugPrint("getSubscriptionStatus user subscription is active.")
} else {
purchaseStatus2 = false
debugPrint("getSubscriptionStatus user subscription is expiring.")
}
case .inBillingRetryPeriod:
debugPrint("getSubscriptionStatus user subscription is in billing retry period.")
purchaseStatus2 = false
case .inGracePeriod:
debugPrint("getSubscriptionStatus user subscription is in grace period.")
purchaseStatus2 = false
case .expired:
debugPrint("getSubscriptionStatus user subscription is expired.")
purchaseStatus2 = false
case .revoked:
debugPrint("getSubscriptionStatus user subscription was revoked.")
purchaseStatus2 = false
default:
fatalError("getSubscriptionStatus WARNING STATE NOT CONSIDERED.")
}
}
} catch {
// do nothing
}
if purchaseStatus1 == true || purchaseStatus2 == true {
purchaseStatus = true
} else if purchaseStatus1 == false && purchaseStatus2 == false {
purchaseStatus = false
}
return
}

After the user initiates the subscription payment, the SDK returns an error type: user cancels. When the user initiates the payment again, Apple will deduct the payment twice and successfully deduct the previously cancelled SKU. This is a recent occurrence with a large amount of data, and the app has not been upgraded in any way. We need to seek help. Thank you

Using NEHotspotConfigurationManager.joinAccessoryHotspot(_ accessory: ASAccessory, passphrase: String) to connect the WiFi, but this function implicitly sets joinOnce to YES.
Is there any api that can use ASAccessory to connect to WiFi while maintaining JoinOnce = false.

Here is an AppleScript script to make it possible double-click files in Finder so that they will be opened in Vim, by Normen Hansen: https://github.com/normen/vim-macos-scripts/blob/master/open-file-in-vim.applescript (it must be used from Automator).
I try to simplify it and also to make it possible to use it without Automator. To use my own version, you only need to save it as application instead, like this:
osacompile -o open-with-vim.app open-with-vim.applescript
and then copy it to /Applications and set your .txt files to be opened using this app.
Here it is, it alsmost works:
-- https://github.com/normen/vim-macos-scripts/blob/master/open-file-in-vim.applescript
-- opens Vim with file or file list
-- sets current folder to parent folder of first file
on open theFiles
set command to {}
if input is null or input is {} or ((item 1 in input) as string) is "" then
-- no files, open vim without parameters
set end of command to "vim;exit"
else
set firstFile to (item 1 of theFiles) as string
tell application "Finder" to set pathFolderParent to quoted form of (POSIX path of ((folder of item firstFile) as string))
set end of command to "cd" & space & (pathFolderParent as string)
set end of command to ";hx" -- e.g. vi or any other command-line text editor
set fileList to {}
repeat with i from 1 to (theFiles count)
set end of fileList to space & quoted form of (POSIX path of (item i of theFiles as string))
end repeat
set end of command to (fileList as string)
set end of command to ";exit" -- if Terminal > Settings > Profiles > Shell > When the shell exits != Don't close the window
end if
set command to command as string
set myTab to null
tell application "Terminal"
if it is not running then
set myTab to (do script command in window 1)
else
set myTab to (do script command)
end if
activate
end tell
return
end open
The only problem is the if block in the very beginning:
if input is null or input is {} or ((item 1 in input) as string) is "" then
What is wrong here? How to make it work? (Assuming it already works fine if AppleScript is used using Automator.)

I have an app with Message Filtering Extension enabled and I have been experiencing unusual behaviour.
When I send messages from local number to local number, the filtering is done correctly, but when I send messages from certain international number to my local number the messages are not filtered. I couldn't find any errors in Console.
I see that the normalisation is correct, is there any specifications for SMS from certain countries? Or a reason why Message Filtering is not activated when a SMS is received?
We have created an app that uses Appintents to plug into Siri. However, launching the app >sometimes< will launch a menu that will let the user choose between the app and Contacts. Why? How can I tell Siri to not ask for Contacts?
The application search for the occurences of a string into files and folders.
Everything work fine until I enable sanbox. Then opendir(path_to_folder) report "Operation not permitted".
By example dp = opendir("/Users/alain/Desktop"); set dp to NULL for my own Desktop.
The application need only read access. How can I get this access ?
I'm working on two Swift applications which are using QUIC in Network.framework for communication, one serve as the listener (server) and the other serve as the client so that they can exchange data, both the server and the client app are running under the same LAN, the problem I met is that when client try to connect to the server, the connection will fail due to boring SSL, couple questions:
Since both the server app and client app are running under the same LAN, do they need TLS certificate?
If it does, will self-signed certificate P12 work? I might distribute the app in App Store or in signed/notarized dmg or pkg to our users.
If I need a public certificate and self signed wouldn't work, since they are just pair of apps w/o fixed dns domain etc, Is there any public certificate only for standalone application, not for the fixed web domain?
When using the old withTaskCancellationHandler(operation:onCancel:isolation:) to run background tasks, you were notified that the background task gets cancelled via the handler being called. SwiftUI provides the backgroundTask(_:action:) modifier which looks quite handy. However how can I check if the background task will be cancelled to avoid being terminated by the system?
I have tried to check that via Task.isCancelled but this always returns false no matter what.
Is this not possible when using the modifier in which case I should file a bug report?
Thanks for your help

I have tried setting a 'apns-expiration' to current time + 30 seconds and also a value '0'. But still my voip app receives the voip push notification after 2-3 minutes. Till this time, caller has already hung up the call. But the receivers phone still rings on receiving the push notification as we have to report it to CallKit.
Am I missing something or there is no way and even 'apns-expiration' does not guarantee timely delivery of Voip push notifications or discard if it is expired.
I have set 'apns-priority' to 10 already as recommended.
Hello, i'm facing issues, when trying to integrate push notification feature into my app. the following message is shown and I don't know how to fix it:
ExportArchive "Runner.app" requires a provisioning profile with the push notifications feature
(Encountered error while creating the IPA)
Thankful for any help! Best regards

I downloaded "Dockkit ADK 1.0" and trying to compile, and some openssl include .h files are missing, for example in HAPBoringSSL.c, the below files can't found:
#include <openssl/bn.h>

where can I get these .h files? I'm worrying about the version conformance if I fetch these files from internet.
