PDFKit PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 18 beta 4 and later / Xcode 16 beta 4.
It worked fine in iOS 17 and earlier (after showing the same issue during the early iOS 17 beta cycle)
It breaks critical functionality that my app relies on.
I have filed feedback (FB14843671).
So far no changes in the latest betas. iOS release date is approaching fast!
Anybody having the same issue? Any workaround available?

Hello everyone,
I have been working on a macOS app that utilizes push notifications for the past year. Up until recently, everything was functioning correctly. However, now I'm experiencing issues where push notifications are either not being delivered at all or are experiencing significant delays, sometimes up to 10 minutes. Setting the priority header to 10 hasn't made any difference. I am currently using development push notifications, but the issue persists when switching to the production environment.
I'm curious if anyone else has encountered similar problems. When checking the push console, it frequently reports that the device is offline, even though it's actually online ("discarded as device was offline"). Occasionally, notifications are delivered promptly, but this is becoming increasingly infrequent.
This issue has been consistently reported by our testers, particularly after they updated to macOS Sonoma. Any insights or assistance you can provide would be greatly appreciated.
Hello!
https://github.com/apple/live-caller-id-lookup-example/blob/main/Sources/PIRService/PIRService.docc/DataFormat.md
The link above shows the data format that the user who gets a call, can get. I wonder if it is also possible to add other fields, for example: "summary". I am currently in the design-phase of an app that aims to present what the last call between the two parties was about, and that information can be gotten from an API that I will build according to Apple's principles that is comaptible with the Live Caller ID Lookup protocol. Therefore adding a field that will present a short summary of the last call will be very handy. Is that possible?
I have a command line utility I wrote that has been working great up until Sequoia that reads the macro keys from a Logitech G600 gaming mouse and turns it in to custom commands. it was using the following code, checking if usage was 0x80:
IOHIDManagerRegisterInputValueCallback(
g600HIDManager,
{ _, returnResult, callbackSender, valueRef in
let elem = IOHIDValueGetElement(valueRef)
let usage = IOHIDElementGetUsage(elem)
let pressed = IOHIDValueGetIntegerValue(valueRef)
Now i'm having issues with opening the HID manager:
IOHIDManagerOpen(g600HIDManager, IOOptionBits.zero)
After changing the system security from permissive to restrictive, It's giving the error code 0xE00002E2, or no permission. I can't easily add the sandbox entitlements as this is just a simple CLI application, not a bundled app, and even after setting back to csrutil disable, i'm still getting this error.
So now i'm trying to turn it in to a bundled app and use CoreHID instead. Unfortunately I'm not getting any notifications that aren't the mouse itself. From the above code that was working before, i was looking for usage values of 0x80. I'm guessing that directly corresponds to the usage 0x80 in the HID descriptor. I am receiving notifications via
await deviceClient!.monitorNotifications(reportIDsToMonitor: [] , elementsToMonitor: [] )
which should pick up everything for the device. I know the usage i'm looking for is referenced in the device client because it's in the deviceClient.elements collection.
So is there something in CoreHID that specifically blocks Vendor specified Usage pages from being picked up by notifications?
I've also tried just requesting the elements using
let elemToMon = await deviceClient?.elements.filter({ ele in
return ele.usage.page == 0xFF80 && ele.usage.usage == 0x80
})
let request = HIDDeviceClient.RequestElementUpdate(elements: elemToMon!)
let results = await deviceClient!.updateElements([request])
but that call errors (still trying to figure out exactly how it errors).
Any help would be appreciated, either in figuring out why i'm not getting the HID reports in question using CoreHID, or even what has changed that is causing me to not be able to use IOKit.hid anymore.
Thanks in advance!

Aloha. Opening and closing VPN tunnels results in as many utun interfaces as the amount of times the tunnel has been opened. These interfaces stay present and seem to be removed only upon system reboot.
We are using the NetworkExtension as a SystemExtension on macOS to create the virtual interfaces.
Is this the normal behaviour. Has anybody else experienced this?

I have simple non-consumable IAPs set up for an app on macOS.
Testing in development with a local .storekit configuration file, everything works as expected.
Testing in development with a remote Sandbox, everything also seems to work fine. Product names and prices fetch correctly, I am able to make purchases with a Sandbox account (both US and UK).
Once I upload a build into TestFlight, IAPs no longer work. The tester would download the Beta app from TestFlight. They open a license manager and can see all the product names, descriptions and prices are pulled from Apple servers correctly (with the correct local currency as well!). So far so good. When trying to purchase any of the IAP, the following error appears:
This is TestFlight so testers are using their real Apple ID. My understanding is that they should continue using their production credentials and a TestFlight Sandbox would be configured behind the scenes automatically.
This error always says the users cannot purchase from a US store and must switch to [whatever user’s actual store location is] store. For example, my account is based in the UK, has got a UK billing address and a UK payment method, and the error tells me to switch to the UK store. People in Canada get a similar error - you must switch from the US store to Canadian. The error makes no sense, the account is already in the desired country.
Clicking on the “Change Store” button opens the App Store app and displays another error: “Cannot Connect to App Store”. Clicking Retry just results in this errors showing again and again.
Clicking OK takes us back to the failed IAP purchase and the final error message appears: “Purchase Error - Unable to Complete Request”.
Things I’ve done / checked:
IAPs are configured in App Store Connect and available for all regions
prices are set for all regions in App Store Connect
IAP name and description localisation in English (UK)
IAP status is Ready to Submit, I don’t think I can go past that unless I make a production release (which I can’t until we fix the problem)
IAP capabilities added in xcode
the problem is not account, machine, or location dependent - every beta tester testing my app on TestFlight has the same issue, they each use a different account and have accounts in different countries
double checked the App Store account location in the App Store settings - it is definitely matching the store this error is asking to switch to
application exits at startup with error 173 if app receipt cannot be found - this one was suggested by the review team, I could not really find any documentation for it
review team also suggested I should add com.apple.security.network.client to enable IAP connectivity. I did add that to one of the builds and it did not help. I am not really convinced this is necessary
Any suggestions on what to check and what to try? I have run out of ideas.
As I've mentioned before our app uses PTT Framework to record and send audio messages. In one of supported by app mode we are using WebRTC.org library for that purpose. Internally WebRTC.org library uses Voice-Processing I/O Unit (kAudioUnitSubType_VoiceProcessingIO subtype) to retrieve audio from mic. According to https://developer.apple.com/documentation/avfaudio/avaudiosession/mode-swift.struct/voicechat using Voice-Processing I/O Unit leads to implicit enabling .voiceChat AVAudioSession mode (i.e. it looks like it's not possible to use Voice-Processing I/O Unit without .voiceChat mode).
And problem is following: when user starts outgoing PTT, PTT Framework plays audio notification, but in case of enabled .voiceChat mode that sound is playing distorted or not playing at all.
Questions:
Is it known issue?
Is there any way to workaround it?
Since the iOS 18 and Xcode 16, I've been getting some really strange SwiftData errors when passing @Model classes around.
The error I'm seeing is the following:
SwiftData/BackingData.swift:409: Fatal error: This model instance was destroyed by calling ModelContext.reset and is no longer usable.
PersistentIdentifier(id: SwiftData.PersistentIdentifier.ID(url: x-coredata://34EE9059-A7B5-4484-96A0-D10786AC9FB0/TestApp/p2), implementation: SwiftData.PersistentIdentifierImplementation)
The same issue also happens when I try to retrieve a model from the ModelContext using its PersistentIdentifier and try to do anything with it. I have no idea what could be causing this.
I'm guessing this is just a bug in the iOS 18 Beta, since I couldn't find a single discussion about this on Google, I figured I'd mention it.
if someone has a workaround or something, that would be much appreciated.
Our company has a VPN client that we develop and it works on 14.x and it was working on 15.x but ever since I have upgraded to 15.1.1, I do not see any traffic being sent to the TUN interface even though I have it configured as the default route. Can anyone provide guidance or insight into what might have changed around the Network Extensions that could have caused this?
Unfortunately I cannot tell if this was happening on 15.0.1. Some things I have tried, to no avail, is disable the firewall and uninstalling/installing of the VPN client. I have no other filters installed that could be interfering. When I try and ping an address I should be able to reach, I get "no route to host"
I have also used Wireshark and have observed zero traffic going to the TUN interface.
NOTE, networking works fine when the VPN client is not connected.
Please help! I have a subscription IAP failing on tvOS 18.2 at:
func makePurchase(_ product: Product) async throws
{
let result = try await product.purchase() //ERROR OCCURS HERE (See error message below)
...
Xcode Console message: "Could not get confirmation scene ID for [insert my IAP id here]"
The IAP subscription was working fine on 18.1 and earlier, and the same IAP and code is also running fine on iOS 18.2. The tvOS error on 18.2 happens both in production and sandbox.
Are there any changes to StoreKit 2 which might cause this error?
Hello everyone,
I used SwiftData for v1 of an app and am now trying to make changes to the schema for v2. I created the v2 schema that adds a property to one of the models.
I need to populate the new property so I made a custom migration using didMigrate. However that doesn't seem to matter what I do in the migration because creating the ModelContainer throws an error before didMigrate ever gets called.
The error is:
Unresolved error loading container Error Domain=NSCocoaErrorDomain Code=134060 "A Core Data error occurred." UserInfo={NSLocalizedFailureReason=Instances of NSCloudKitMirroringDelegate are not reusable and should have a lifecycle tied to a given instance of NSPersistentStore.}
Higher up in the Xcode output I see things like this (in order):
Request 'D25A8CB8-7341-4FA8-B2F8-3DE2D35B5273' was cancelled because the store was removed from the coordinator.
BUG IN CLIENT OF CLOUDKIT: Registering a handler for a CKScheduler activity identifier that has already been registered
CloudKit setup failed because it couldn't register a handler for the export activity. There is another instance of this persistent store actively syncing with CloudKit in this process.
How can I know from this output what I am doing incorrectly?
Any idea what I should take a look at or try to do differently?
This is a simple app with three models and nothing fancy. The only change in the schema is to add a property. The new property is declared as optional and has an inverse that is also declared as optional.
Thanks for any insight!
When testing In-App Purchases in Xcode with a .storekit file, I can delete past purchase transactions, so I can re-test the purchase experience.
I've switched to using a Sandbox tester and made purchases. However, I cannot find how to delete previous purchase transactions made in the sandbox so I can re-run the tests.
Is this possible?
I am working on an app for a home automation device.
If I were using HomeKit exclusively I could add custom services or custom characteristics on standard services and these things would all be reported to my app via HomeKit. There is sample code from Apple that demonstrates how to do this.
When a Matter device is commissioned using HomeKit you might expect custom clusters and/or custom attributes in a standard cluster would be translated to appropriate HomeKit services and characteristics, but this doesn't appear to be the case.
Is there a way to have HomeKit do this?
If not it seems I would need to use Matter directly rather than via HomeKit to access custom features. But if I commission the device using Matter in my app then I understand a new fabric is created and the device would not show in the Home app. Maybe the user needs to commission the device twice, once with my custom app and once with the Home app? That seems like a poor user experience to me. Perhaps that is the price paid for using a cross-platform standard?
Is there a better way to get the same level of customization using Matter that I am able to get using HomeKit?
We have an application which is written in Swift, which activates Transparent Proxy network extension.
Our Transparent Proxy module is a system extension, which is exposing an app proxy provider interface (We are using NETransparentProxyProvider class and in extension’s Info.plist we use com.apple.networkextension.app-proxy key.)
We are using JAMF MDM profile for installing our transparent proxy in customer environment. We are using VPN payload(https://developer.apple.com/documentation/devicemanagement/vpn) for this network system extension.
This payload does not have any field for order.
As per https://developer.apple.com/documentation/devicemanagement/vpn/transparentproxy-data.dictionary documentation there is another payload for TransparentProxy and we could create a Transparent Proxy profile using iMazingProfile Editor.
Noticed that, if we add the Order attribute to the VPN/TransparentProxy payload, while installing the extension, the save to preferences fails with "Error in saving TP configuration in updateOnDemandRule permission denied" error.
Can we use this Order field to ordering the installed Transparent Proxy extension in a machine?
Customer devices will likely have other Transparent Proxy network extensions as well. We want to allow the Customer to control the order in which each Transparent Proxy network extension receives the network traffic.
How can we set the order of the Transparent proxy extension that can be deployed using MDM profile with VPN/TransparentProxy payload?
Attached the TransparentProxy payload profile for the reference.

I'm developing wallet extension for my app and using sandbox for testing. It was working properly on iOS 17, then I updated to iOS 18 and now the Wallet doesn't recognize my extension. It passes on 'status' method, but doesn't reach the 'passEntries' method.
Does it have any solution?
If an app has a text filtering extension and associated server that the iPhone OS communicates with, then how can that communication be authenticated?
In other words, how can the server verify that the request is valid and coming from the iPhone and not from some spoofer?
If somebody reverse engineers the associated domain urls our of the app's info.plist or entitlement files and calls the server url directly, then how can the server detect this has occurred and the request is not coming from the iPhone OS of a handset on which the app is installed?
I'm using the iOS simulator with a StoreKit configuration file. I can see that there have been transactions while the app has been closed, but my StoreKit 2 listener is never called with those updates to be able to finish them When I open my app from a cold start.
I've added a listener on application(_:didFinishLaunching:launchOptions:) like this:
func startObservingTransactions() {
task = Task(priority: .background) {
for await result in Transaction.updates {
if case .verified(let transaction) = result {
await transaction.finish()
}
}
}
}
But the Transaction.updates loop never gets called (have added breakpoints to check). It's only ever called when a purchase is made, or subsequent transaction renewals when the app is open. Only then it will get the previously unfinished transactions.
Steps to reproduce:
Create an app with a StoreKit config file (with sped up transactions) to purchase an item
Make a purchase then quit the app
Wait for a bit for more transactions to be made while the app is closed.
Open the app from a cold start and none of the transactions will be finished by the listener in your app. Cancel the subscription via the transaction manager.
Close and open the app from a cold start. The first transaction will be finished by the listener but none of the others will be.
In Apple's docs it says
If your app has unfinished transactions, the listener receives them immediately after the app launches
Why is this not the case?
[Q] Has there been a change in macOS 15.3.2 and later that can explain why some UDP traffic is not seen by some Network Extensions when it is in previous macOS minor and major versions?
I am looking for a lightweight server that can run inside an app.
The key requirement is that it must support local IP communication over HTTPS.
I have searched Google and found several frameworks, but as far as I know, support for HTTPS in this environment has been discontinued or is no longer available.
If anyone knows a solution that meets these criteria, I would greatly appreciate your guidance.
Thank you in advance!😀

Hello Everyone,
I’m working on a project that involves multicast communication between processes running on different devices within the same network. For all my Apple devices (macOS, iOS, etc.), I am using NWConnectionGroup, which listens on a multicast address "XX.XX.XX.XX" and a specific multicast port.
The issue occurs when a requestor (such as a non-Apple process) sends a multicast request, and the server, which is a process running on an Apple device using NWConnectionGroup (the responder), attempts to reply. The problem is that the response is sent from a different ephemeral port rather than the port on which the multicast request was received.
If the client is behind a firewall that blocks unsolicited traffic, the firewall only allows incoming packets on the same multicast port used for the initial request. Since the multicast response is sent from a different ephemeral port, the firewall blocks this response, preventing the requestor from receiving it.
Questions:
Is there a recommended approach within the NWConnectionGroup or Network.framework to ensure that responses to multicast requests are sent from the same port used for the request?
Are there any best practices for handling multicast responses in scenarios where the requestor is behind a restrictive firewall?
Any insights or suggestions on how to account for this behavior and ensure reliable multicast communication in such environments would be greatly appreciated.
Thanks,
Harshal
