Hello,
I'm building this mobile app using Quasar - Capacitor on iOS.
The app is working perfectly, but I'm encountering an issue whenever I push the rep I get this error: "Error
Unable to open base configuration reference file '/Volumes/workspace/repository/ios/App/Pods/Target Support Files/Pods-App/Pods-App.release.xcconfig'.
App.xcodeproj:1"
I've tried every possible solution and made sure that everything is set perfectly.
Can anyone please help me with that?
Thanks in advance, appreciate you 🫶🏻

Hi everyone.
I’m working on an iOS app that uses Firebase Cloud Messaging (FCM) to send push notifications. I’m encountering an issue when trying to send notifications either from Firebase Functions or directly using the FCM token with the Firebase Admin SDK and REST API.
Error Message:
FirebaseMessagingError: Auth error from APNS or Web Push Service
code: 'messaging/third-party-auth-error'
message: 'Auth error from APNS or Web Push Service'
What I’ve Set Up:
iOS App Registered in Firebase
Bundle ID: Kilovative-Designs.ParkAware
APNs Key downloaded from Apple Developer Portal
Team ID and Key ID correctly entered in Firebase Console
Firebase Admin SDK Service Account setup and used for sending
Device is successfully receiving FCM tokens
Subscribed to topics and calling Messaging.messaging().subscribe(toTopic:) works
Using firebase-admin to send FCM messages via sendToDevice or sendToTopic
What I’ve Tried:
Tested push via firebase-admin in Node.js (got same APNs auth error)
Tested with both topic-based and direct token-based push
Confirmed the .p8 key is uploaded in Firebase, with correct Key ID and Team ID
Tried generating a new APNs Auth Key
Firebase Admin SDK is initialized with the correct service account
Using Node.js firebase-admin with a known good FCM token, and sending this payload:
{
notification: {
title: "Test Notification",
body: "This is a direct FCM test"
},
token: "cxleOwi73EhFh9C5_V4hED:APA91bE3W..."
}
Returns: FirebaseMessagingError: Auth error from APNS or Web Push Service
Questions:
Are there known conditions under which Firebase throws this error even if the APNs Auth Key is present?
Does the Bundle ID need to start with com. in the Apple Developer Portal and Firebase for APNs authentication to work?
Could this be a certificate or provisioning profile mismatch issue (even when using a .p8 key)?
Is there a way to manually validate APNs authentication from Firebase outside of actual push delivery?
Any insight or guidance would be incredibly helpful. I’m new to developing and have tried repeated efforts to fix this issue but still haven’t resolved it.
Thanks in advance!

In the online documentation for InstallerJS, it is stated that the unit for the availableKilobytes property of the target field is kilobytes.
Isn't it actually bytes because of a bug in the very first release of macOS that supported InstallerJS?
[Q] Has there been a fix in the recent years regarding this property that would explain why the documentation says it's kilobytes? Even though at the time of this writing, the unit is still bytes when you call my.target.availableKilobytes
I'm using this call to dump the value of this property in install.log:
system.log(my.target.availableKilobytes + '');
Ref. https://developer.apple.com/documentation/installer_js/target/1811975-availablekilobytes
(FB20448952)
I'm calling this command to export archive:
xcodebuild -exportArchive -archivePath .build/XYZ.xcarchive -exportPath .build/XYZ.ipa -exportOptionsPlist Authenticator/ExportOptions.plist -quiet -allowProvisioningUpdates
Here is my exportOptions file content
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>method</key>
<string>app-store-connect</string>
<key>signingStyle</key>
<string>automatic</string>
<key>teamID</key>
<string>ABCD</string>
</dict>
</plist>
Most of the time this command fail with this error:
error: exportArchive No Accounts
error: exportArchive No signing certificate "iOS Distribution" found
What we found is that our Apple ID just disappear from Xcode and we need to add it again manually.
So there are two questions here:
Why Apple ID account dissapears and how I can fix this?
Is there an option to not use Apple ID account in Xcode and for example to use -authenticationKeyID flags of xcodebuild?
Just to mention this happens only on our CI machine and not locally.
We are developing a cross platform c++ application. We also use some objective-c (no swift) and specific Apple frameworks like AVFoundation, CoreML in the MacOs version of our software.
We use Apple Clang as compiler when building for MacOs. As our code is primarily c++ we would like to use the latest and greatest c++ 20 features.
So we are looking into using vanilla clang instead, the builds with vanilla clang seem to work fine, however our concern is that we might have overlooked possible issues that could arise. So our question is whether there are specific things we need to address when switching compilers, are there things that we need to be aware of?
In the end we just want to know if switching compilers won't cause problems we can't oversee.
So we would like to know if others took the same steps and what your thoughts/experiences are regarding this?

I'm on Mac Studio with Apple M1 Max and I recently upgrated to Sequoia 15.4. After that, Docker won't run anymore.
I tried almost all proposed solutions on the web to make Docker to work with Sequoia 15.4 (e.g. workaround at GitHub), without success.
Because of this, now I'm stuck in all of my development activities. For example, I cannot develop and deploy anymore my projects and applications.
What can I make to solve that?

I regularly see questions from folks who’ve run into problems with their third-party IDE on macOS. Specifically, the issue is that their IDE is invoking Apple’s command-line tools — things like clang and ld — and that’s failing in some way. This post collects my ideas on how to investigate, and potentially resolve, issues like this.
If you have any questions or comments, please put them in a new thread here on DevForums. Tag it appropriately so that I see it. Good tags include Compiler, Linker, LLVM, and Command Line Tools.

Investigating Third-Party IDE Integration Problems
Many third-party IDEs rely on Apple tools. For example, the IDE might run clang to compile C code or run ld to link object files. These IDEs typically don’t include the tools themselves. Rather, they rely on you to install Xcode or Apple’s Command Line Tools package. These are available at Apple > Developer > Downloads
Occasionally I see folks having problems with this. They most typically report that basic stuff, like compiling a simple C program, fails with some mysterious error. If you’re having such a problem, follow the steps below to investigate it.
IMPORTANT Some IDEs come with their own tools for compiling and linking. Such IDEs are not the focus of this post. If you have problems with an IDE like that, contact its vendor.
Select Your Tools
macOS has a concept of the current command-line tools. This can either point to the tools within Xcode or to an installed Command Line Tools package. To see which tools are currently selected, run xcode-select with the --print-path argument. This is what you’ll see if you have Xcode installed in the Applications folder:
% xcode-select --print-path
/Applications/Xcode.app/Contents/Developer
Note All of the tools I discuss here are documented in man pages. If you’re not familiar with those, see Reading UNIX Manual Pages.
And this is what you’ll see with a Command Line Tools package selected.
% xcode-select --print-path
/Library/Developer/CommandLineTools
There are two common problems with this:
It points to something you’ve deleted.
It points to something unexpected.
Run the command above to see the current state. If necessary, change the state using the --switch option. For example:
% xcode-select --print-path
/Applications/Xcode.app/Contents/Developer
% clang -v
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
…
% sudo xcode-select --switch ~/XcodeZone/Xcode-beta.app
% clang -v
Apple clang version 15.0.0 (clang-1500.0.38.1)
…
I have Xcode 14.3 in the Applications folder and thus clang runs Clang 14.0.3. I have Xcode 15.0b5 in ~/XcodeZone, so switching to that yields Clang 15.0.0.
It’s possible to run one specific command with different tools. See Select Your Tools Temporarily, below.
Run a Simple Test
A good diagnostic test is to use the selected command-line tools to compile a trivial test program. Consider this C [1] example:
% cat hello.c
#include <stdio.h>
int main(int argc, char ** argv) {
printf("Hello Cruel World!\n");
return 0;
}
% clang -o hello hello.c
% ./hello
Hello Cruel World!
IMPORTANT If possible, run this from Terminal rather than, say, over SSH.
You may need to expand this test program to exercise your specific case. For example, if your program is hitting an error when it tries to import the Core Foundation framework, add that import to your test program:
% cat hello.c
#include <stdio.h>
#include <CoreFoundation/CoreFoundation.h>
int main(int argc, char ** argv) {
printf("Hello Cruel World!\n");
return 0;
}
When you compile your test program, you might see one of these results:
Your test program compiles.
Your test program fails with a similar error.
Your test program fails with a different error.
I’ll explore each case in turn.
[1] For a C++ example, see C++ Issues, below.
If your test program compiles…
If your test program compiles from the shell, that proves that your basic command-line tools setup is fine. If the same program fails to compile in your IDE, there’s something IDE-specific going on here. I can’t help you with that. I recommend that you escalate the issue via the support channel for your IDE.
If your test program fails with a similar error…
If your test program fails with an error similar to the one you’re seeing in your IDE, there are two possibilities:
There’s a bug in your test program’s code.
There’s an environmental issue that’s affecting your command-line tools setup.
Don’t rule out the first possibility. I regularly see folks bump into problems like this, where it turns out to be a bug in their code. For a specific example, see C++ Issues, below.
Assuming, however, that your test program’s code is OK, it’s time to investigate environmental issues. See Vary Your Environment, below.
If your test program fails with a different error…
If your test program fails with a different error, look at the test program’s code to confirm that it’s correct, and that it accurately reflects the code you’re trying to run in your IDE.
Vary Your Environment
If your test program fails with the same error as you’re seeing in your IDE, and you are sure that the code is correct, it’s time to look for environmental factors. I typically do this with the steps described in the next sections, which are listed from most to least complex.
These steps only tell you where things are going wrong, not what is going wrong. However, that’s often enough to continue the investigation of your issue.
Vary Your Shell
Try running your commands in a different shell. macOS’s default shell is zsh. Try running your commands in bash instead:
% bash
…
bash-3.2$ clang -o hello hello.c
bash-3.2$ ./hello
Hello Cruel World!
Or if you’ve switched your shell to bash, try it in zsh.
Vary Your User Account
Some problems are caused by settings tied to your user account. To investigate whether that’s an issue here:
Use System Settings > Users & Groups to create a new user.
Log in as that user.
Run your test again.
Vary Your Mac
Some problems are system wide, so you need to test on a different Mac. The easiest way to do that is to set up a virtual machine (VM) and run your test there. Or, if you have a separate physical Mac, run your test on that.
Vary Your Site
If you’re working for an organisation, they may have installed software on your Mac that causes problems. If you have a Mac at home, try running your test there.
It’s also possible that your network is causing problems [1]. If you have a laptop, try taking it to a different location to see if that changes things.
[1] I rarely see this when building a simple test program, but it do see it with other stuff, like code signing.
C++ Issues
If you’re using C++, here’s a simple test you can try:
% cat hello.cpp
#include <iostream>
int main()
{
std::cout << "Hello Cruel World!\n";
}
% clang++ -o hello hello.cpp
% ./hello
Hello Cruel World!
A classic problem with C++ relates to name mangling. Consider this example:
% cat hello.c
#include <stdio.h>
#include "hello-core.h"
int main(int argc, char ** argv) {
HCSayHello();
return 0;
}
% cat hello-core.cpp
#include "hello-core.h"
#include <iostream>
extern void HCSayHello() {
std::cout << "Hello Cruel World!\n";
}
% cat hello-core.h
extern void HCSayHello();
% clang -c hello.c
% clang++ -c hello-core.cpp
% clang++ -o hello hello.o hello-core.o
Undefined symbols for architecture x86_64:
"_HCSayHello", referenced from:
_main in hello.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The issue here is that C++ generates a mangled name for HCSayHello:
% nm hello-core.o | grep HCSayHello
0000000000000000 T __Z10HCSayHellov
whereas C uses the non-mangled name:
% nm hello.o | grep HCSayHello
U _HCSayHello
The fix is an appropriate application of extern "C":
% cat hello-core.h
extern "C" {
extern void HCSayHello();
};
Select Your Tools Temporarily
Sometimes you want to temporarily run a command from a particular tools package. To continue my earlier example, I currently have Xcode 14.3 installed in the Applications folder and Xcode 15.0b5 in ~/XcodeZone. Xcode 14.3 is the default but I can override that with the DEVELOPER_DIR environment variable:
% clang -v
Apple clang version 14.0.3 (clang-1403.0.22.14.1)
…
% DEVELOPER_DIR=~/XcodeZone/Xcode-beta.app/Contents/Developer clang -v
Apple clang version 15.0.0 (clang-1500.0.38.1)
…

Hello,
According to documentation, the App Store does not re-download the entire app when updating, but instead generates an update package containing only the changed content compared to the previous version.
I’d like to clarify the following points:
1. Granularity of file changes
If only part of a large file changes, does the update package include the entire file, or does it patch only the modified portions within that file?
2. Guideline on separating files
The documentation recommends separating files that are likely to change from those that are not. How should this be interpreted in practice?
3. Verifying the diff result
Is there a way for developers to check the actual diff result of the update package generated by the App Store without submitting the app?
Is there a diff command tool or comparison method closer to the actual App Store update process?
4. Estimating update size during development
For apps with large-scale resources, minimizing update size is critical.
Are there any tools or best practices to estimate the size of the update package before submitting to the App Store?
Any clarification or reference materials would be greatly appreciated.
Thank you.

I am converting a project to expo and have created a new expo project. I have migrated most of the react-native code but need to add a native module. I added it using npx create-expo-module expo-settings --local
The name of the module DataRetrieval.
So far so good but I need a package SwiftCSV. I added it as a dependency to Pods and did a npx pod-install but when I try to import SwiftCSV as a subproject, it is not found. So I tried adding to the DataRetrieval podspec an s.dependency 'SwiftCSV'. I then get an error that there is a redefining of symbols. I am able to include this in a regular Swift file but not in the sub-module under expo. What am I missing about how to not only add a native module but to add dependencies and include it in my project?
Thanks,
Ray

Testing and Debugging Code Running in the Background
I regularly see questions like this:
My background code works just fine in Xcode but fails when I download the app from the App Store.
or this:
… or fails when I run my app from the Home screen.
or this:
How do I step through my background code?
These suggest a fundamental misunderstanding of how the debugger interacts with iOS’s background execution model. The goal of this post is to explain that misunderstanding so that you can effectively test and debug background code.
Note The focus of this post is iOS. The advice here generally applies to any of iOS’s ‘child’ platforms, so iPadOS, tvOS, and so on. However, there will be some platform specific differences, especially on watchOS. This advice here doesn’t apply to macOS. It’s background execution model is completely different than the one used by iOS.
Understand the Fundamentals
The key point to note here is that the debugger prevents your app from suspending. This has important consequences for iOS’s background execution model. Normally:
iOS suspends your app when it’s in the background.
Once your app is suspended, it becomes eligible for termination. The most common reason for this is that the system wants to recover memory, but it can happen for various other reasons. For example, the system might terminate a suspended app in order to update it.
Under various circumstances your app can continue running after moving to the background. A great example of this is the continued processed task feature, introduced in iOS 26 beta.
Alternatively, your app can be resumed or relaunched in the background to perform some task. For example, the region monitor feature of Core Location can resume or relaunch your app in the background when the user enters or leaves a region.
If no app needs to be executing, the system can sleep the CPU.
None of this happens in the normal way if the debugger is attached to your app, and it’s vital that you take that into account when debugging code that runs in the background.
An Example of the Problem
For an example of how this can cause problems, imagine an app that uses an URLSession background session. A background session will resume or relaunch your app in the background when specific events happen. This involves two separate code paths:
If your app is suspended, the session resumes it in the background.
If your app is terminated, it relaunches it in the background.
Neither code path behaves normally if the debugger is attached. In the first case, the app never suspends, so the resume case isn’t properly exercised. Rather, your background session acts like it would if your app were in the foreground. Normally this doesn’t cause too many problems, so this isn’t a huge concern.
On the other hand, the second case is much more problematic. The debugger prevents your app from suspending, and hence from terminating, and thus you can’t exercise this code path at all.
Seek Framework-Specific Advice
The above is just an example, and there are likely other things to keep in mind when debugging background code for a specific framework. Consult the documentation for the framework you’re working with to see if it has specific advice.
Note For URLSession background sessions, check out Testing Background Session Code.
The rest of this post focuses on the general case, offering advice that applies to all frameworks that support background execution.
Run Your App Outside of Xcode
When debugging background execution, launch your app from the Home screen. For day-to-day development:
Run the app from Xcode in the normal way (Product > Run).
Stop it.
Run it again from the Home screen.
Alternatively, install a build from TestFlight. This accurately replicates the App Store install experience.
Write Code with Debugging in Mind
It’s obvious that, if you run the app without attaching the debugger, you won’t be able to use the debugger to debug it. Rather:
Extract the core logic of your code into libraries, and then write extensive unit tests for those libraries. You’ll be able to debug these unit tests with the debugger.
Add log points to help debug your integration with the system.
Treat your logging as a feature of your product. Carefully consider where to add log points and at what level to log. Check this logging code into your source code repository and ship it — or at least the bulk of it — as part of your final product. This logging will be super helpful when it comes to debugging problems that only show up in the field.
My general advice is that you use the system log for these log points. See Your Friend the System Log for lots of advice on that front.
One of the great features of the system log is that disabled log points are very cheap. In most cases it’s fine to leave these in your final product.
Attach and Detach
In some cases it really is helpful to debug with the debugger. One option here is to attach to your running app, debug a specific thing, and then detach from it. Specifically:
To attach to a running app, choose Debug > Attach to Process > YourAppName in Xcode.
To detach, choose Debug > Detach.
Understand Force Quit
iOS allows users to remove an app from the multitasking UI. This is commonly known as force quit, but that’s not a particularly accurate term:
The multitasking UI doesn’t show apps that are running, it shows apps that have been run by the user. The UI shows recently run apps regardless of whether they’re in the foreground, running in the background, suspended, or terminated. So, removing an app from the UI may not actually quit anything.
Removing an app sets a flag that prevents the app from being launched in the background. That flag gets cleared when the user next launches the app manually.
Note In some circumstances iOS will not honour this flag. The exact cases where this happens are not documented and have changed over time.
Keep these behaviours in mind as you debug your background execution code. For example, imagine you’re trying to test the URLSession background relaunch code path discussed above. If you force quit your app, you’ll never hit this code path because iOS won’t relaunch your app in the background. Rather, add a debug-only button that causes your app to call exit.
IMPORTANT This suggestion is for debugging only. Don’t include a Quit button in your final app! This is specifically proscribed by QA1561.
Alternatively, if you’re attached to your app with Xcode, simply choose Product > Stop. This is like calling exit; it has no impact on your app’s ability to run in the background.
Test With Various Background App Refresh Settings
iOS puts users in control of background execution via the options in Settings > General > Background App Refresh. Test how your app performs with the following settings:
Background app refresh turned off overall
Background app refresh turned on in general but turned off for your app
Background app refresh turned on in general and turned on for your app
IMPORTANT While these settings are labelled Background App Refresh, they affect subsystems other than background app refresh. Test all of these cases regardless of what specific background execution feature you’re using.
Test Realistic User Scenarios
In many cases you won’t be able to fully test background execution code at your desk. Rather, install a TestFlight build of your app and then use the device as a normal user would. For example:
To test Core Location background execution properly, actual leave your office and move around as a user might.
To test background app refresh, use your app regularly during the day and then put your device on charge at night.
Testing like this requires two things:
Patience
Good logging
The system log may be sufficient here, but you might need to investigate other logging solutions that are more appropriate for your product.
These testing challenges are why it’s critical that you have unit tests to exercise your core logic. It takes a lot of time to run integration tests like this, so you want to focus on integration issues. Before starting your integration tests, make sure that your unit tests have flushed out any bugs in your core logic.

Hi, I am having an issue with xcodebuild -showdestinations command.
Steps to reproduce:
Create a new iOS application project in Xcode or use an existing one.
Navigate to this project in a terminal.
Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations
What I expect:
All destinations available in the Xcode UI should be listed.
What I get:
It depends. For new projects, I consistently get only generic platform destinations and my connected physical device.
When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes.
Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably?

My App is not compatible with iPhone 15 but can run on iPhone 14 perfectly fine, what could be the problem?
I am new to App development.
Hello,
I'm encountering an issue when trying to build and launch a Flutter app on a physical iOS device using Android Studio.
Here is the full log:
`Launching lib/main.dart on (iPhone Name) in debug mode...
Automatically signing iOS for device deployment using specified development team in Xcode project: (Project ID)
Running Xcode build...
Xcode build done. 19.7s
Failed to build iOS app
Could not build the precompiled application for the device.
Error (Xcode): Target debug_unpack_ios failed: Exception: Failed to codesign (Project Names)/build/ios/Debug-iphoneos/Flutter.framework/Flutter with identity (identity ID).
Error launching application on (iPhone Name).`
This only happens when using Android Studio.
When I build the same project using Xcode, it runs fine on the same device.
Background:
I accidentally deleted all Apple accounts from Xcode recently.
In Keychain Access, I had three identical certificates; I deleted the older two and kept the newest one.
I suspect this may be related to provisioning or code signing, but I’m not sure how to resolve it within Android Studio.
Any advice or steps to fix this would be greatly appreciated.
I created a new test project in Xcode using the iOS > App template, enabled automatic signing in Signing & Capabilities, and selected my team.
I then tried building and installing the app on a real device, and it worked successfully.
This confirms that there are no issues with code signing or provisioning on the Apple side.
Thanks in advance!

Hi,
I'm generating MusicKit JWT tokens on my backend side and using it on the client side to query the Apple Music API. One concern I have is accidentally over issuing the scope of this JWT, resulting in accidental access more services than intended like DeviceCheck or APNS.
Other than using separate keys for MusicKit and other services, is there a way to limit the generated JWT to only the Apple Music API (https://api.music.apple.com/v1/*) using the JWT payload scope?

I filed FB16715590 about this. I have a vague memory this might be related to some code to pretend to be case insensitive, but I can't find it now.
Up to now I've been building my x64 binaries on Sequioa specifying a target macOS level of 13.4. That worked fine.
In an attempt to debug a problem that was causing some pain I created a 13.4 x64 build environment and tried to build the code there.
This code:
using CacheKeyType = std::filesystem::path;
using CacheValueType = std::tuple<LoadedImage, int, bool>; // <image, lastUse, currentlyLoading>
using CacheType = std::unordered_map<CacheKeyType, CacheValueType>;
friend class ThreadLoader;
static inline constexpr int16_t MAXIMAGESINCACHE = 20;
static inline constinit std::atomic_int age{ 0 };
static inline std::shared_mutex rwMutex{};
static inline CacheType imageCache{};
got me the following errors:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk/usr/include/c++/v1/__hash_table:838:5: error: static_assert failed due to requirement 'integral_constant<bool, false>::value' "the specified hash does not meet the Hash requirements"

Which isn't "mega-helpful" :(
I thought that specifying:
set(CMAKE_OSX_DEPLOYMENT_TARGET 13.4 CACHE STRING "Minimum operating system version for deployment" FORCE)
would have made the compilations use the same headers as for Ventura above, but it seems not?
Is this to be expected?

So, as we found out from WWDC, the migration to Apple Silicon is inevitable.
Does anyone have a good recommendation for a replacement for Macintosh Common Lisp on Apple Silicon? I was using it back in the MPW days and struggling to keep the Lisp code working, but Apple Silicon has thrown a money wrench at it!
Thanks in advance for any advice on any available Apple Silicon Lisp development tools!

Hello all,
I am building a simple Flutter app, and I want to support entering the app through an email.
I have used flutter deep links on android and all works well, but for some reason on IOS it doesnt.
What I have achieved:
When clicking the link I do get navigated into the app, but I get navigated to whatever the last screen was, regardless of the path in the URL. Furthermore, the logical code inside the app doesnt seem to run either - no logs are printed etc.
I have even tried following the flutter tutorial at https://docs.flutter.dev/cookbook/navigation/set-up-universal-links
to the letter, and it doesnt work
I am using:
Flutter 3.22.3
Go Router 14.2.7
Thanks in advance

Is it recommended to turn off 'Charge Limit' if I leave my iPhone plugged into my Mac all day for development? I want to minimize battery degradation.
Thanks
