hi!
recently, I reinstalled my computer to get gptk2. I found such an error when loading rosetta. when I typed "softwareupdate --install-rosetta" on the terminal, the terminal feedback was "Installing Rosetta 2 on this system is not support Ed."
besides, when I use homebrew install gptk, it will return "Error: openssl @1.1 has been disabled because it is not supported upstream! It was disabled on 2024-10-24."
Is there any way to solve these problems?

Problem
The following code doesn't work:
let predicate = #Predicate<Car> { car in
car.size == size //This doesn't work
}
Console Error
Query encountered an error: SwiftData.SwiftDataError(_error: SwiftData.SwiftDataError._Error.unsupportedPredicate)
Root cause
Size is an enum, #Predicate works with other type such as String however doesn't work with enum
Enum value is saved however is not filtered by #Predicate
Environment
Xcode: 15.0 (15A240d) - App Store
macOS: 14.0 (23A339) - Release Candidate
Steps to reproduce
Run the app on iOS 17 or macOS Sonoma
Press the Add button
Notice that the list remains empty
Expected behaviour
List should show the newly created small car
Actual behaviour
List remains empty inspite of successfully creating the small car.

On an app that was using the old API for In-App Purchases (StoreKit 1). The app is already published on the App Store. The purchase is non-consumable.
While trying to migrate to StoreKit 2, I'm unable to restore purchases.
Specifically displaying and purchasing products works as expected, but when deleting and reinstalling the app, and then trying to restore purchases I can't do it.
I'm trying to restore them using the new APIs but it doesn't seem to be working.
What I have tried so far:
I'm listening for transaction updates during the whole lifetime of the app, with:
Task.detached {
for await result in Transaction.updates {
if case let .verified(safe) = result {
}
}
}
I have a button that calls this method, but other than prompting to log in again with the Apple ID it doesn't seem to have any effect at all:
try? await AppStore.sync()
This doesn't return any item
for await result in Transaction.currentEntitlements {
if case let .verified(transaction) = result {
}
}
This doesn't return any item
for await result in Transaction.all {
if case let .verified(transaction) = result {
}
}
As mentioned before I'm trying this after purchasing the item and deleting the app. So I'm sure it should be able to restore the purchase.
Am trying this both with a Configuration.storekit file on the simulator, and without it on a real device, in the Sandbox Environment.
Has anyone being able to restore purchases using StoreKit 2?
PD: I already filed a feedback report on Feedback Assistant, but so far the only thing that they have replied is:
Because StoreKit Testing in Xcode is a local environment, and the data is tied to the app, when you delete the app you're also deleting all the transaction data for that app in the Xcode environment. The code snippets provided are correct usage of the API.
So yes, using a Configuration.storekit file won't work on restoring purchases, but if I can't restore them on the Sandbox Environment I'm afraid that this won't work once released, leaving my users totally unable to restore what they have already purchased.
Hi all, I'm working on a really basic counter app as a way to explore SwiftData and have come across some behavior that I don't understand. I have a very simple App Intent that increments a user-specified counter in my app. The intent doesn't throw any errors and correctly updates the CoreData store but, when I switch back to my app from the Shortcuts app (where I'm testing the app intent), the view hasn't updated. Closing and re-opening the app shows the incremented counter value but I'd like to know if it's possible to have my app's UI update when the CoreData store is updated from outside the app without relaunching the whole app.
For some brief context, here's my view and the App Intent:
struct ContentView: View {
@Environment(\.modelContext) private var modelContext
@Query private var counters: [Counter]
// ...
var body: some View {
NavigationStack {
List {
ForEach(counters) { counter in
CounterRowItem(counter: counter)
}
.onDelete(perform: deleteItems)
}
// ...
}
}
struct IncrementCounterIntent: AppIntent {
static var title: LocalizedStringResource = "Increment Counter"
@Parameter(title: "Name", optionsProvider: CounterOptionsProvider()) var name: String
func perform() async throws -> some IntentResult & ReturnsValue<Int> {
let provider = try CounterProvider()
guard let counter = try provider.fetchCounters().first(where: { $0.name == name }) else {
print("Couldn't find counter with name '\(name)'")
return .result(value: 0)
}
counter.count += 1
try provider.context.save()
return .result(value: counter.count)
}
private final class CounterOptionsProvider: DynamicOptionsProvider {
func results() async throws -> [String] {
try CounterProvider().fetchCounters().map { $0.name }
}
}
}
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?
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?
My use case is the following:
Every user of my app can create as an owner a set of items.
These items are private until the owner invites other users to share all of them as participant.
The participants can modify the shared items and/or add other items.
So, sharing is not done related to individual items, but to all items of an owner.
I want to use CoreData & CloudKit to have local copies of private and shared items.
To my understanding, CoreData & CloudKit puts all mirrored items in a special zone „com.apple.coredata.cloudkit.zone“.
So, this zone should be shared, i.e. all items in it.
In the video it is said that NSPersistentCloudKitContainer uses Record Zone Sharing optionally in contrast to hierarchically record sharing using a root record.
But how is this done?
Maybe I can declare zone „com.apple.coredata.cloudkit.zone“ as a shared zone?

I'm trying to debug a problem that's affecting customers who have upgraded to WatchOS 10, and I'm unable to get any console output from the watch when I debug the watch app in Xcode, or from the console app connecting from my Mac.
The other weird thing is that my watch shows up twice in the device list in the console app.
Is this a known issue?
I'm trying to migrate from Complication with CLKComplication to WidgetKit.
I have implemented the required methods in https://developer.apple.com/documentation/widgetkit/converting-a-clockkit-app, but the migration is not working. There is no evidence that the method for migration is also called.
It was the same with Xcode 14.0.1 and Xcode 14.1RC.
class ComplicationController: NSObject, CLKComplicationDataSource, CLKComplicationWidgetMigrator {
...
@available(watchOS 9.0, *)
var widgetMigrator: CLKComplicationWidgetMigrator {
return self
}
@available(watchOS 9.0, *)
func widgetConfiguration(from complicationDescriptor: CLKComplicationDescriptor) async -> CLKComplicationWidgetMigrationConfiguration? {
return CLKComplicationStaticWidgetMigrationConfiguration(kind: "MyWidget", extensionBundleIdentifier: "com.example.myapp.mywatchkitapp.mywidget")
}
}
What's wrong? Has anyone been able to migrate?
Users are reporting that 3rd-party software that leverages Apple's Network Extensions (such as LuLu and Windows Defender) are causing networking issues after upgrading to macOS 15.
However as such products were working seamlessly on macOS 14.* and nothing in the code of these products changed between then and now, this would point to bug in macOS.
Users have mentioned the following work arounds:
Disabling the internal (macOS) firewall
Upgrading to macOS 15.1 beta
More info about the issues and these "workarounds" here and here..
Looking for any guidance / insight / technical details from Apple, as users are (understandably) blaming these tools and their developers 😭
Of course if there are updated APIs or some other changes in macOS 15 that developers should consider / conform to, to ensure compatibility that'd be great to know too!

Here we have yet another bug, I suppose, in SwiftData that happens on iOS18 but it is not an issue on iOS17.
There are 2 models defined as follows
@Model
final public class Note: Identifiable, Codable, Hashable
{
public private(set) var uuid = UUID().uuidString
var heading: String = ""
var tags: [Tag]?
init(heading: String = "") {
self.heading = heading
}
required public init(from decoder: Decoder) throws {
...
}
public func encode(to encoder: Encoder) throws {
...
}
}
@Model
final public class Tag: Identifiable, Codable
{
var name: String = ""
@Relationship(deleteRule: .nullify, inverse: \Note.tags) var notes: [Note]?
init(_ name: String) {
self.name = name
}
required public init(from decoder: Decoder) throws {
…
}
public func encode(to encoder: Encoder) throws {
...
}
}
and a function o add new tags as follows
private func addTags(note: Note, tagNames: [String]) {
if note.tags == nil {
note.tags = []
}
for tagName in tagNames {
if let tag = fetchTag(tagName) {
if !note.tags!.contains(where: {$0.name == tagName}) {
note.tags!.append(tag)
}
} else {
// The following line throws the exception on iOS18 when Tag conforms to Codable:
// Illegal attempt to map a relationship containing temporary objects to its identifiers.
note.tags!.append(Tag(tagName))
}
}
}
This code works perfectly well on iOS17 but on iOS18 I get the exception “Illegal attempt to map a relationship containing temporary objects to its identifiers.”
What I noticed that this happens only when Tag model conforms to Codable protocol. Is it a bug? It looks like, otherwise we've got some undocumented changes have been made.
In my previous post I mentioned about the other issue about ModelContext that is broken too on iOS18 - I mean it works perfectly well on iOS17.
Demo app with an example how to workaround this problem is available here on GitHub.
Repro steps:
Add a note with some tags (separated by space)
Edit this note and add a new tag (tag that does not exists in database) and tap Save.
You should noticed that the tag hasn't been added. It works occasionally but hardly to be seen.
Recently I've been working on a demo project called iLibrary. The main goal was to learn more about CloudKit and SwiftData. After a while I noticed that there were some hangs/freezes when running the app in debug mode.
I first tried this with Xcode 15.4 and iOS 17.5. Here the hang only appears at the beginning, but only for a few seconds. But when I exit debug mode, there are no more hangs.
With Xcode 16 beta 4 and iOS 18 it looks completely different. In this case, the hangs and freezes are always present, whether in debug mode or not. And it's not just at the beginning, it's throughout the app. I'm aware that this is still a beta, but I still find this weird. And when I profile this I see that the main thread gets quite overloaded. Interestingly, my app doesn't have that many operations going on. So I guess something with the sync of SwiftData or my CloudKitManger where I fetch some records from the public database is not running fine.
Lastly, I wanted to delete the iCloud app data. So I went to Settings and tried to delete it, but it didn't work. Is this normal?
Does anyone have any idea what this could be? Or has anyone encountered this problem as well? I'd appreciate any support.

I've been using DeviceActivityMonitor for 2 years, and recently noticed the following issue, starting in iOS 17.5 (another user also reported here).
For a sizable percentage of my users, device activity event thresholds get triggered together. My app sends notifications for every hour of screen time during the DeviceActivitySchedule using event thresholds. Often users will get, for example, the 1, 2, and 3 hour screen time notifications all at the same time.
I have a hypothesis for why this is happening: the system sometimes terminates the app extension for various reasons, one being if the 6MB memory limit is reached. It seems as though the retry policy is to retry the failed threshold at the next event threshold. And if the following threshold also fails, they can pile up until the next one succeeds. I think this is a new retry policy since iOS 17, and I believe this because:
There used to be a bug where the same threshold was triggered multiple times in a row, indicating that the failed threshold was retried immediately. This bug is no longer around and it's been replaced by the one I am reporting.
According to my logs, thresholds that get triggered together are also called earlier when they are supposed to be called - but the callback function does not complete. So this indicates that the threshold isn't just called late, but that it is called once and then retried again later.
If anyone could answer the following questions I'd be super grateful:
Is there ANY way to log when the system terminates the app extension and for what reason? And not just on my own device, but for all our users in production (because it's hard to reproduce this issue, as it only happens for some portion of our users). Maybe some kind of crash report or failure callback that will allow my to ping my server?
Could anyone at Apple could confirm my hypothesis about the new retry policy causing this issue?
iOS 18 announced improvements to the Wallet Passes. Does anyone have a link to the updated documentation? The old documentation does not have the changes as of the time of this post. There is a video, however, there are no specifications for the the new image formats (e.g., artwork.png).
Hi,
In macOS26 beta, our app icon is not showing anymore in the MenuBar. It is also not displayed in the new section "Menu Bar > Allow in the Menu Bar", which seems to be the way to show/hide Menu Bar icons in macOS 26.
The icon is correctly displayed and working in macOS 15. Our app is signed and notarized. It also has the "LSUIElement" value set to "true" in the Info.plist file.
Is there some new mandatory entitlements to add in order to have our app showing in the "Allow in the Menu Bar" section?
Thanks in advance for your help.
Regards

Hello,
I’m reaching out to gather information regarding the upcoming changes to APNs certificates that are set to be implemented in the beta at the end of January 2025.
Specifically, I would like to understand the following:
What will be the practical impact of these changes on apes apis ?
What actually needed to be done at trust store for this changes, and how will it affect our current setup?
What steps do we need to take to update the certificates on our servers?
it’s crucial for us to address these changes in advance and keep our customers informed.
Thank you for your help!
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?
Since upgrading to iOS 18, an issue has been observed where blocked incoming calls display "(null)" instead of the actual application name. At the time the calls defined by the same application contain the name of the application correctly.
My app features two kinds of widgets, let's call them kind A and kind B.
I have both A and B widgets on my Home Screen. When I tap the button on widget A (associated with App Intent), I expect widget B to also reload.
However, if you call WidgetCenter.shared.reloadAllTimelines() inside the perform() method of the AppIntent, the timeline of widget B does not reload immediately. This issue only occurs on a physical device and is not consistently reproducible. On a simulator, however, widget B reloads as expected.

Hello,
Has anyone encountered issues with CoreBluetooth advertising and scanning between iOS 18/iPadOS 18 Beta 3 ? I'm want to know this is a bug or an intended change in behavior.
Issue Summary:
Central device on iOS 18/iPadOS 18 Beta 3 (foreground) and Peripheral device on iOS 17.5.1 (background) fail to communicate via BLE advertising.
The reverse setup or using non-iOS 18 devices works as expected.
Detailed Description:
I am developing an iOS/iPadOS application using CoreBluetooth for advertising and scanning. Here are the specifics of my setup:
The application uses a fixed BLE service UUID, and scanning is performed with the specified service UUID.
Background Modes Uses Bluetooth LE accessories and Acts as a Bluetooth LE accessory are enabled to allow advertising and scanning even when the app is in the background.
When the Central device is running iOS 18/iPadOS 18 Beta 3 and the app is in the foreground scanning, and the Peripheral device is running iOS 17.5.1 with the app in the background advertising, the Central device cannot receive the advertisements from the Peripheral device. ( CBCentralManagerDelegate.centralManager(_:didDiscover:advertisementData:rssi:) don't work.)
In the reverse scenario (Central on iOS 17.5.1 in the foreground scanning, and Peripheral on iOS 18/iPadOS 18 Beta 3 in the background advertising), the advertisements are received correctly.
Additionally, advertisements are received correctly in cases where both devices are not on iOS 18/iPadOS 18.
I am wondering if anyone else has encountered this issue or if there is any information available regarding whether this is a bug or an intended behavior change in iOS 18/iPadOS 18.
Thank you.
