Imagine we have an Xcode workspace containing two projects:
MyLibrary.xcodeproj holding a framework target
MyShortcutsApp.xcodeproj holding an app target which consumes MyLibrary framework
Both targets define App Intents and the ones from MyLibrary are exposed via AppIntentsPackage accordingly.
When trying to wrap the App Intent from framework as App Shortcut and passing localized AppShortcutPhrases I do see the following compile error:
".../Resources/de.lproj/AppShortcuts.strings:11:1: error: This AppShortcut does not map to a known action (MyLibraryIntent specified). (in target 'MyShortcutsApp' from project 'MyShortcutsApp')"
If I use the same localized App Shortcut phrases for an App Intent which is locally defined in the app target, everything works fine and also if I use the framework-provided App Intent in and App Shortcut without passing any localized phrases.
This is happening with Xcode 16.0 (16A242d), with 16.1 (16B40) and with 16.2 beta 2 (16C5013f).
I already raised this issue via FB15701779 which contains a sample project to reproduce and to further analyze the issue.
Thanks for any hint on how to solve that.

The app gets stuck after login on an iOS 18 device. It works in Xcode, but the simulator shows the following console error: IntegrationApp(769,0x1f0094c00) malloc: xzm: failed to initialize deferred reclamation buffer (46).
I'm working with the Screen Time API in iOS and have successfully implemented the following:
Granted Screen Time Permission: The app asks for and obtains Screen Time permissions without any issues.
Blocked Specific Apps: Using FamilyActivitySelection, I can block access to certain apps.
Monitoring Device Activity: With DeviceActivityCenter().startMonitoring(), I’m able to successfully start monitoring.
DeviceActivityCenter().startMonitoring(.myActivity, during: schedule)
Now, I’m wondering if there’s a way to detect exactly which app the user opens, so I can fire an API from my own app based on that event.
Is this kind of real-time app usage detection possible with the Screen Time API? If so, how might it be implemented?
Hi,
In my app, I have an option to remove a contact from a contact group (using the Contacts framework), and it's been working fine till recently users of the macOS version reported that it's not working. I have been using the CNSaveRequest removeMember(contact, from: group) API. The same API works fine on iOS. I'm not sure when it started but it seems to be affecting macOS14.6 as well as 15.1.
I was able to reproduce it in a small test project as well, and have the same experience (the API works on iOS but not on macOS), so it definitely seems like a problem with the framework. Can someone confirm this, and/or suggest a workaround?
Here's the code I run to test it out ...a simple SwiftUI view that has 4 buttons:
Create contact and group
Add contact to group
Remove contact from group
(optional) cleanup by deleting contact and group
It's the 3rd step that seems to fail on macOS, but works fine on iOS.
Here's the code to test it out:
struct ContentView: View {
let contactsModel = ContactsStoreModel()
var body: some View {
VStack (alignment: .center, spacing: 15){
Button ("1. Add Contact And Group") {
print("add contact button pressed")
contactsModel.addTestContact()
if let _ = contactsModel.createdContact {
print("created contact success")
}
}
Button ("2. Add Contact To Group") {
print("add to group button pressed")
contactsModel.addContactToGroup()
}
Button ("3. Remove Contact From Group") {
print("remove from group button pressed")
contactsModel.removeContactFromGroup()
}
Button ("4. Delete Contact and Group") {
print("remove from group button pressed")
contactsModel.deleteContactAndGroup()
}
}
.padding()
}
}

Hi everyone,
I'm experiencing crashes that consistently occur on iOS 18 devices, which seem to share a common root cause. I'm hoping for some guidance. Here are the details of the crashes as received from Xcode Organizer:

Notable Points:
All crashes occur only on iOS 18 and newer versions.
The crashes are independent of the Xcode version used to build the app (tested with both Xcode 15.4 and 16).
All crash traces occur in CoreFoundation and seem to have nothing related to our app codebase.
I've attempted to profile the app using Instruments to identify any zombie objects, but the crashes do not manifest on my own devices.
I've referred to discussions, including this forum thread, but have not yet found a solution.
Questions:
Has anyone else encountered similar issues on iOS 18?
Are there specific aspects of iOS 18 that might contribute to these CoreFoundation and libobjc-related crashes?
Would appreciate any suggestions for further diagnostics or potential workarounds.
Thank you for your help!

Recent Incident with SDKAnalytics Version 11.11.4
We recently released version 11.11.4 of SDKAnalytics for use in the SuperApp. This update introduced several significant changes since the last generated version, 11.11.0. The previous version's primary change was the migration of the integration pipeline and its identifier from OQ6 to FW6. Additionally, we performed refactoring and adjustments to the project's configurations.
In SDKAnalytics, we use XcodeGen to simplify project setup and minimize conflicts. We also rely on CocoaPods to create and manage our Pods/Frameworks.
The SuperApp, where SDKAnalytics is implemented, operates as a centralized ecosystem. Its products and user journeys are segregated into Pods/Frameworks, distributed across multiple repositories, following a multi-repo structure. Currently, the app includes over 300 Pods.
Starting from version 11.11.1 of our SDK, we implemented some important project changes. However, when we released version 11.11.4, which included a new feature for the SuperApp, we encountered a critical issue.
Incident Overview
All SDKs implemented in the SuperApp have their loading times monitored. After updating SDKAnalytics from version 11.11.0 to 11.11.4, the loading time spiked from 200 ms to 3000 ms. Faced with this significant impact, we launched a task force to investigate and resolve the issue.
Investigation and Diagnosis
After several days of investigation, we carefully reviewed the numerous pull requests merged between versions 11.11.0 and 11.11.4. As a strategy, we reverted the project.yml configurations from version 11.11.4 to match those of version 11.11.0. This rollback resolved the loading time issue, indicating that the problem stemmed from the project's configuration.
Upon deeper analysis, we identified the culprit: a single line of configuration. The Bundle ID for the SuperApp follows the pattern com.companyname.enterprise. However, in version 11.11.4, SDKAnalytics adopted a new Bundle ID format: com.companyname.SDKAnalytics. This change directly impacted the SDKAnalytics loading time when implemented in the SuperApp.
Solution
To resolve the issue, we reverted this configuration. We modified the Bundle ID for SDKAnalytics to br.com.SDKAnalytics, removing the com.companyname prefix. After this change, the loading time returned to normal.
Reflection
The lingering question remains: What is the logical explanation for this discrepancy in loading time caused by the Bundle ID configuration? This behavior is unexpected, and we plan to investigate further to understand the underlying technical reasons.

iOS 18 is the worst update to the Apple photos app ever. There was nothing wrong with iOS 17 photos app. You guys took a perfectly usa and funtio app and thought of myriad different ways to make it less intuitive and usable. Why even mess with the favorites pictures album. You have to scroll down/up scroll through your favorites when for your regular pictures you have to swipe up/down to scroll. Completely nonsensical. ios 18 is a downgrade to the photos app in e way

Been enjoying the ios18 Beta. Wanted to provide something I noticed since upgrading to the Beta. When I stop an episode midway through and add the episode back to my queue, my phone now skips the episode as already played. So i either miss the rest of the episode, if I don’t catch it, or have to go back and reset it, to hear the partially finished episode. Hopefully this can be addressed in future updates! :)
I'm trying (in Swift) to use CryptoKit to generate the required JWT for the Apple Music Web API, as documented (sort of) here.
But I'm getting 401s no matter what I try. I found some examples of generating JWTs online, but something isn't working here. I've set up my identifiers and gotten an API secret through my account in the dev portal. It's associated with an identifier requesting Music API access (I requested all three available Music-related capabilities).
For the secret, I'm using the long key string from the .p8 file I generated and downloaded from the dev portal.
Here's what I've tried:
struct APIToken
{
struct Header: Encodable
{
let alg = "HS256"
let kid: String
}
struct Payload: Encodable
{
let iss: String
let iat: String
let exp: String
}
static func tokenize(keyID: String, issuerID: String, secret: String) -> String
{
let privateKey = SymmetricKey(data: Data(secret.utf8))
let headerJSONData = try! JSONEncoder().encode(Header(kid: keyID))
let headerBase64String = headerJSONData.base64EncodedString()
let currUnixTime = Int(Date().timeIntervalSince1970)
let expUnixTime = currUnixTime + 5 * 2628288 // five months of seconds
let payloadJSONData = try! JSONEncoder().encode(Payload(iss: issuerID, iat: "\(currUnixTime)", exp: "\(expUnixTime)"))
let payloadBase64String = payloadJSONData.base64EncodedString()
let toSign = Data((headerBase64String + "." + payloadBase64String).utf8)
let signature = HMAC<SHA256>.authenticationCode(for: toSign, using: privateKey)
let signatureBase64String = Data(signature).base64EncodedString()
let token = [headerBase64String, payloadBase64String, signatureBase64String].joined(separator: ".")
print(token)
return token
}
}
I also tried making sure the base64 strings are URL-safe with this extension:
extension Data
{
func URLSafeBase64EncodedString() -> String
{
return base64EncodedString()
.replacingOccurrences(of: "+", with: "-")
.replacingOccurrences(of: "/", with: "_")
.replacingOccurrences(of: "=", with: "")
}
}
but that made no difference.
All the documentation says is
A decoded developer token has the following format.
{
"alg": "ES256",
"kid": "ABC123DEFG"
}
{
"iss": "DEF123GHIJ",
"iat": 1437179036,
"exp": 1493298100
}
After you create the token, sign it with your MusicKit private key using the ES256 algorithm.
Am I not doing that? Any insight appreciated.
I have released a watchOS-specific application that retrieves data from the iPhone calendar app and displays it on the Apple Watch.
It uses the calendars function in EKEventStore to retrieve the list of calendars, but it seems that it sometimes fails to retrieve iCloud calendars.
Trouble is, this problem only occurs in a very few users‘ environments, the majority of other users’ environments are able to retrieve them without any problems, and I cannot reproduce it at all in my environment.
Local calendars and Google calendars seem to be retrieved without any problems.
Minimal example code:
import SwiftUI
import EventKit
struct ContentView: View {
let eventStore = EKEventStore()
@State var success: Bool = false
@State var calendarNames: [String] = [String]()
func request() async {
success = (try? await eventStore.requestFullAccessToEvents()) ?? false
}
func list() {
calendarNames = eventStore.calendars(for: .event).map { $0.title }
}
var body: some View {
VStack {
Image(systemName: "globe")
.imageScale(.large)
.foregroundStyle(.tint)
Text("Access: \(success.description)")
ScrollView {
ForEach(calendarNames, id: \.self) { name in
Text(name)
}
}
}
.onAppear {
Task {
await request()
list()
}
}
.padding()
}
}
I asked the user experiencing the problem to try restarting the iPhone and Apple Watch, reinstalling the app and re-pairing them, but there was no change.
I would appreciate any information you can provide.
Best regards.

Has anyone experienced frozen images when having camera on video recording mode? For example i live in Los Angeles and sometimes I like to record the sunrise or sunset or while I’m crossing a bridge but my video camera kinda freezes and doesn’t record. I’ve already checked my memory and I have more than enough to not have issues maybe it’s a setting issue? if anyone has a solution or suggestions please let me know thank you.

I've found an app that has a call blocking feature an is able to add more than 10_000_000 entries. As I understand it doesn't use more than one extension for it because I see only one in the Call Blocking & Identifying settings menu. How to implement that? My limit now is around 1_800_000 entries.
I want to understand how it manages memory allocation if i need more memory later than the memory i specified during initialisation . Does it allocates new chunk of memory and dellocate older memory or does it already allocated more memory than i asked for in first place? Just want to understand how exactly this calculation is done ?
And i do initialisation of NSMutableString in swift , will these same principle of expension applied there ?
Hi all.
Since upgrading to a new iPhone 16 pro, running 18.2 public beta, I'm having issue with my wallpaper/Lock Screen.
If AOD is turned OFF, my lock screen is almost too dim to read, and the chosen Lock Screen wallpaper has a blurred effect on it.
if AOD is ON, the screen is still too dim to read, and the wallpaper is just a faint shade of the colour of the image chosen.

Crash occurs in @MainActor class or function in iOS 14
Apps built and distributed targeting Xcode 16 version swift6 crash on iOS 14 devices.
We create a static library and put it in our app's library.
Crash occurs in all classes or functions of the static library (@MainActor in front).
It does not occur from iOS / iPadOS 15.
If you change the minimum supported version of the static library to iOS 11, a crash occurs, and if you change it to iOS 14, a crash does not occur.
Is there a way to keep the minimum version of the static library at iOS 11 and prevent crashes?
