There are CarPlay resources from Apple (https://developer.apple.com/documentation/carplay/) but it seems entirely geared towards iOS app development. Are there any resources or documentation that help with CarPlay integration on the vehicle/head unit side of things? I believe you need to download the CarPlay Communication Plug-In and integrate that with the head unit platform and applications, but there isn't much documentation that comes along with the Plug-In .zip download. Is there a different place where resources for head unit developers is located?

Hello, I am currently learning SwiftUI through a paid course and am working on integrating Firebase into my project. While trying to add the Firebase package through Xcode, everything seems to work fine except for the fact that I am unable to find the FirebaseFirestoreSwift package. I am using the latest versions of both Xcode and macOS. I have attached a screenshot from the package manager where I couldn't locate the FirebaseFirestoreSwift package. Could you kindly assist me in resolving this issue? How can I correctly add this specific package to my project? Thank you for your support.

https://developer.apple.com/documentation/metrickit I am unable to get the MetricKit logs for past 24 hours time period on my test flight build. I have been able to achieve immediate logs for crash, cpu exception and diskwrite exceptions. But the logs which contains all the crashes, cpu exceptions and diskwrite exceptions, battery and network details, etc for the previous day/24h are never generated. I have used the following method to log the payloads in the file systems. I have tested the same on normal xcode builds as well as TestFlight build. func didReceive(_ payloads: [MXDiagnosticPayload]) https://developer.apple.com/documentation/metrickit/mxmetricmanagersubscriber/didreceive(_:)-9yd4u

Bonjour, Depuis la mise jour de Xcode, j'ai deux erreurs dans le Runner que je n'arrive pas à résoudre. Merci pour votre aide.

We have noticed that the hang reports provided in Xcode include the percentage of hang time, which are used to sort from high to low (effectively sorting by priority). However when adding these percentages up we do not get 100%. For newer releases the total may be quite low (5-20%) but even for older releases we only get up to around 85%. Are there reports we are missing? Is there a threshold or something that lower percentage reports are not hitting? Any level of understanding here would be appreciated!

I have updated my firebase with the latest version, but on simulator, apple log in and parsing from firebase server is not working on iOS 18 when working fine on the actual test device. However iOS 17 simulator works perfect as X-Code 15. And previews are not working as well with my current app coding, which was coded in previous X-code 15. Is there any API changes? Any help? Or 18.1 might fix this bug?

I test my app, by building it and hoping it will go on my iOS. This is the only workflow I have to test my testing app. I use AVAudioEngine and AVAudioSession. It sounds painful but, yes. I literally comment out parts and build the app everytime and see if it would crash or not. Sometimes I'd get Crash Logs in the Analytics part, but I haven't managed to get them there anymore. So I had no more Crash Logs. I was wondering if there's a function or something. Maybe something that I can do in AppDelegate to make it create a Crash Log somewhere? Uncaught Exception overwrite, didn't solve the issue for me. It really has to be an actual crash log, something that catches these. If someone knows, let me know! Thanks

I am new. I have never used Swift nor XCode or the CLI. But I have found and managed to test my App that I created for testing on my iPhone. I have absolutely no intentions to put it on the App Store. I even made it Open-Source on GitHub. I learned a lot of things and ways to prevent crashes, but unfortunately I am slowly starting to lose the ability to put my App on my iOS. I am new here as a developer. But I have troubles to create a Developer Account, so I am not sure what I should do. Here's what I think I am having issues with: I feel like you can only create a Developer Account if you have a business, is this true? I really find it cool to test my own App on my own phone. But I want to do it in an official way. But I don't know how. Others have told me that you'd need a License for the App Store. But I am not trying to put it on the App Store, will this make it impossible for me to test my own app? Why make an app if not putting it on the App Store? You can learn. If you make good Apps or Libraries, you can provide them to other Developers! Maybe even an opportunity to collab with someone and even indeed put it on the App Store with a valid Developer Account. Seriously, if I wouldn't have been able to test my iOS app through other ways on my iPhone, I'd have never been able to make a short breakdown about AVAudioEngine and AVAudioSession. I've seen people that have run into these crashes. I tried to look up for a fix, but found none. I saw apps that allowed you to use a Microphone on a Laptop/PC and I decided to make my own one to test, and succeded, while I yet need to figure out a few crashes, I managed to do it, and I really want to continue and actually use my own App... So I was really happy that I could make a post to provide a guide in hopes that it would help someone. And I would do more, but I really need help with figuring out how I can test my own app on my own phone. I hope that Developer Relations can help with this.

I've got a bunch of AudioUnit projects approaching release, and am attempting to build an installer for them. All are based on the AudioUnit template in Xcode 14. What actually governs how the system detects an AudioUnit? The instructions I have seen say that the built .appex should be renamed to have the extension .component and installed into /Library/Audio/Plug-Ins/Components/ - great, I am able to build a signed installer that does that (i.e. strip out the built Application project that is part of the AudioUnit template but useless to, say, a Logic Pro user), include the .appex that declares the plugin and embeds a Framework that contains the actual code (so it can be loaded in-process). auval -l does not show it after running the installer, nor does Console show anything logged suggesting that it was found but malformed or something like that. Meanwhile, simply building the project causes auval -l to show an install of it in the build directory, and I have noticed that if I delete that, auval -l would still show the plugin installed, but now in the location I exported an archive of the project (!!). What black magic is this? However, deleting both the recent build and the archive, after running the installer, and there is no indication that AudioComponentRegistry even sees the copy of it in one of the two locations actually documented to be valid install locations for an AudioUnit. I have, however, installed one third-party free AUv3 which installed into /Library/Audio/Plug-Ins/Components/ Am I misunderstanding something about how this works? Is there some string other than AudioComponentRegistry I should filter on in Console that might provide a clue why my AudioUnit installed there is not picked up? Must I ship the semi-pointless Application that is part of the Xcode template project, and whatever magical mechanism detects it when I build will work its magic on end-users' machines? Or could the problem be that the Framework with the actual code under Contents/Frameworks inside the audio unit, rather than installed independently into /Library/Frameworks?

I wanted to take an old iPhone 11 Pro and downgrade from iOS 18 beta to iOS 17 for testing. I can download today (Sept 26) the restore image for the iPhone 11 Pro (and many others) but when I try to restore it (Finder Option click, select restore image), Apple rejects it (I guess they won't sign it). If find this to be a problem. There is no reason why an iPhone in developer mode can't be used for testing a release less than a few weeks after the next release comes out. Why do they have the restore images if you can't use them? Why is there no restore images for iOS 17.7?

I cannot open the Runner.xcworkspace on xcode even though i have tried everything (all ran with cleaned and not cleaned derived data) -i am running xcode on the latest version -tried deleting/installing again/updating pods more than enough times -tried opening from terminal/xcode/finder (all end up either opening Runner.xcodeproj or not opening at all) what are other options left to do ?

I'm trying to make an xcframework from my static library (SPM btw) with macros.

I bought a new iPhone 16, iOS18 (22A3354). Data is synced from the old device. The old device has a certificate under Settings - General - "VPN & Device Management". The iPhone16 device is not synced to the certificate. After I manually added it on my iPhone16, I didn't find the certificate in Settings - General - About - certificate trust settings. I tried restarting and reimporting, it still doesn't work. Erase the iPhone and re-import the certificate, which is successfully trusted. I tried another iPhone 15 device, upgraded to iOS18. After the certificate is imported, the certificate is successfully trusted. The problem seems to be related to data synchronization to iOS18 devices. Is this just a bug? Is there any solution?

Previously, it was possible to download the dSYM file from the App Store Connect account. However, Apple has recently discontinued this option. How can you obtain the necessary dSYM file for Firebase?

So I'm working on a large client app with lots of frameworks and modules which is is a mix of Xcode frameworks with 3rd party dependencies in CocoaPods and newer/converted SPM modules. Essentially CocoaPods is used to set the 3rd party dependencies on various Xcode frameworks, which also depend on each other via manual set dependencies, plus a bunch of SPM modules which are also manually added. It's a bit of a mess. The problem we encountered the other day started when I added a new protocol to one of the SPM modules. Nothing special about it, all types from Foundation and the app built and ran perfectly in simulator with a Debug build. However when we switched to building a Release build, it failed to link, logging an error indicating it could not resolve the new protocol in a number of the Xcode framework projects. The resolutions go like this: The Xcode app project has some manually added Xcode frameworks. Those frameworks have manually added dependencies on a second Xcode framework. That second framework has an SPM dependency on the module where my protocol lives. So Xcode App -> 1st Xcode framework -> 2nd Xcode framework -> SPM module. Now the 2nd Xcode framework directly uses my protocol from the SPM module. But the 1st Xcode framework neither uses or imports the SPM module. Yet the error we get when building for Release is that the 1st Framework is unable to resolve the protocol from the SPM module even though it's completely oblivious to it. My working theory is that something in the way a Release build works is insisting that when linking the 1st Xcode framework, it has to resolve the 2nd Xcode framework, which then has to resolve types from the SPM modules, but for some reason and only in a Release build, it's unable to. So our current workaround has been to add the SPM module as a dependency to all 1st level Xcode frameworks that have the 2nd Xcode framework as a dependency. That works because when linking the 1st Xcode framework, it has a direct reference to the module even though the code never imports anything from it. Does this should correct?

Every now and again, I see that Python 3.8 crashes. Now, I tried to get rid of all Python 3.8 interpreters on my system. But the crash log for this one gives a Path of /Users/USER/*/python3.8. What does that mean? That's not a real path on my filesystem. The crash is due to Python not finding a dylb it needs: Process: python3.8 [2946] Path: /Users/USER/*/python3.8 Identifier: python3.8 Version: ???

I don’t know if this Python was installed by Apple, or if I got via one of the dozens of SDKs I've installed over the years. VS Code has a way to search for Python interpreters, and I used that to delete all the old ones I could find. And I'm pretty sure macOS is on a more recent version.

I downloaded a program from Stanford University and am trying to get it to work on my iPhone. The program works on my computer, but when I try to upload it to the App Store, I get all sorts of errors. I am running Xcode 16 on a Max Studio. When I run the compiler, I get a message: “The iPhone needs to be prepared for development, and development services need to be enabled. Ensure that the device is unlocked.” I am confused by the term “unlocked.” Is the message referring to a lock by carrier or an on-device lock? How do I enable development services? -Merwyn
