Yes, I'm looking for ways to achieve the same behavior without using an .exp file at all. Using the exports file is neither an issue nor any bug (apologies for the wrong terminology), I'm just looking for any other ways that do not use an exports file. Thanks.

We’re developing an AVFoundation-based video recording app (4K @ 60 fps required for biomechanical analysis). On most devices this works perfectly (iPhone 12/14/15/16 non-Pro models), but on several iPhone Pro models (12 Pro, 13 Pro, 14 Pro, 15 Pro/Pro Max), we consistently get 4K 30 fps recordings—even when the device should support 4K 60 fps on the wide-angle camera. What we observe We configure the session for .hd4K3840x2160. We iterate through AVCaptureDevice.formats and select formats that: have 3840×2160 resolution support ≥60 fps (videoSupportedFrameRateRanges) On some Pro devices, this format search returns no results, even though: The Camera app records 4K60 fine. External references list the wide camera as 4K60 capable. The fallback becomes the device's default 4K30 format, so final files are 3840×2160 @ 30 fps. This happens immediately on app launch (not after heating), so not thermal-related. What we’ve tried Force selecting .builtInWideAngleCamera instead of dual/triple cameras. Disablin
Hi @roth-izo , You have to use productbuild command to create an archive which will bundle all the child packages inside and create a main archive. productbuild --synthesize --package pkg1 --package pkg2 path/distribution.dist Once the distribution.dist file is created, you can use following command to create the final package. productbuild --distribution path/distribution.dist --package-path --identifier com.xxx.xxx --version xxxx --sign xxxx --timestamp /Package.pkg In the distribution.dist you can put other restriction you need. Please refer https://developer.apple.com/library/archive/documentation/DeveloperTools/Reference/DistributionDefinitionRef/Chapters/Distribution_XML_Ref.html regards Prema Kumar

Hi team, I’m having an issue with my iOS app related to local network communication and connecting to a Wi-Fi speaker. My app works similar to the “4Stream” application. The speaker and the mobile device must be on the same Wi-Fi network so the app can discover and connect to the speaker. What’s happening: When I run the app directly from Xcode in debug mode, everything works perfectly. The speaker gets discovered. The speaker gets connected successfully. The connection flow completes without any problem. But when I upload the same build to TestFlight, the behaviour changes completely. The app gets stuck on the “Connecting…” screen. The speaker is not discovered. But the same code is working fine on Android It never moves forward from that state. So basically: Debug Mode: Speaker is detected and connected properly TestFlight: Stuck at “Connecting…”, speaker does NOT get connected This makes me believe something related to local network access, multicast, Wi-Fi info permissions, or Bonjour discovery is not bei
hi, guys, their documents is terrible, you can only get the resolution range in header files comment. Besides, did you tried 640x480 resolution in VTFrameRateConversion? I have this problem:https://developer.apple.com/forums/thread/808646

Makes sense, so seems like what I saw back then [1] almost certainly wasn't at the APFS layer, then. one follow-up comment for the haters out there: Ha, well I would hope that someone looking at an FSKit-related question on the forums would know enough about file systems to understand why that would make sense, though I suppose you never know ;) COW is definitely saving me more space on my machine than whatever is reserved for that purpose. [1] If you're curious it was an old Apple Watch I had that got stuck in a boot loop after restarting it to try to fix some crashy app behavior, and IIRC there were low storage alerts shortly before that happened. Definitely way after the iOS 8 days.

(2) All other activity came from Preview(2407). There were three threads tied to your KEXT: One thread is doing handling I/O from the VM system, caused by memmove, probably tied to memory-mapped file I/O: userFrames: [ [_platform_memmove, libsystem_platform.dylib, null, 0x1804ad320, 96], [CGPDFSourceRefill, CoreGraphics, (CGPDFSource.c:464), 0x1869dfff8, 164], kernelFrames: [ [thread_invoke, kernel.release.t8103, (sched_prim.c:3530), 0xfffffe0008a6b0e8, 1180], [thread_block_reason, kernel.release.t8103, (sched_prim.c:4147), 0xfffffe0008a69b5c, 244], [lck_rw_lock_shared_gen, kernel.release.t8103, (lock_rw.c:1375), 0xfffffe0008a4f404, 892], [IORWLockRead, kernel.release.t8103, (lock_rw.c:1524), 0xfffffe0008a4f030, 144], [11, 315180], [11, 316328], [11, 70956], [11, 70608], [11, 236500], [cluster_io, kernel.release.t8103, (vfs_cluster.c:2336), 0xfffffe0008c1fb74, 3512], [cluster_pagein_ext, kernel.release.t8103, (vfs_cluster.c:2736), 0xfffffe0008c219b8, 244], [cluster_pagein, kernel.release.t8103, (vfs_

Hello! Thanks for taking the time to write about this. This doesn't sound right, and is probably a bug. But to be sure, we need some more information to investigate. Can you please file a bug report and include code sample sysdiagnose logs video recording to the following link? https://developer.apple.com/bug-reporting/ The site will walk you through these steps. You can reply what the Feedback ID is for this issue and I'll make sure it gets to the right team to investigate.

I'm not sure why Xcode Signing Certificate status is Failed with the above configuration. It doesn't seem to me that DriverKit and the provisioning file expect & as the expected value. Based on the above, isn't it Xcode that expects &? I'm suspicious of Xcode's behavior. I was able to get a look at your account configuration this morning, and I think I can explain what's going on. For reference, I looked at the bundle with this structure: com.0.DextPCIe **Short answer: ** Change your Entitlement.plist configuration to Development Only entitlement configuration: com.apple.developer.driverkit.transport.pci IOPCIPrimaryMatch 0xFFFFFFFF&0x00000000 ...and I think you'll find that your build will suddenly work fine. Note that it's perfectly fine to use the configuration above for normal testing and development. The entitlement above does match all devices, but your IOKitPersonalities dictionary controls what you ACTUALLY match against, so having an broad entitlement doesn't mean you'll matc

Huh. Out of curiosity, did APFS always do that to prevent that issue? No, at least not entirely. I don't remember if it was an issue on macOS (where booting support wasn't added until later), but there was a short interval in iOS 8 where it was possible to completely fill an iOS device. However, the end result of that wasn't quite as bad as I made it sound (or it theoretically could be). The nature of COW also means that in a normal I/O flow, the I/O request that uses the last available space is effectively guaranteed to be the writes for the next/new data that's going to be written. So what actually ended up happening was: The kernel panicked, since APFS couldn't really do anything else. The file system was left in a dirty state (since it didn't unmount). The fsck prior to remount found that pending data and cleared it (since that's all it could really do). ...which then freed up enough space for the file system to be functional again, at least enough that you could delete files an

Hi, Both situations are known. 500 is the limit for apps. That's worth filing an enhancement request (same as a bug report but to be treated as an enhancement). As you've noticed as well, images are not lazy loaded. Also worth filing an enhancement request. To make the process go faster make sure your image sizes aren't larger than the maximum size provided by the given list item. You can also file this as a bug report and please include a time profile. If you can file, I'll do my best to get a response for you. Rico Car Experience - Software Engineer

At best, if your phone allows notifications (local, push) you can display notifications in CarPlay BUT, they cannot have any special interaction. There isn't a supported use case (at least based on the present information in this forum post) for an entitled CarPlay app to do what you are suggesting. That said, to @DTS Engineer's point you can request Apple add support for such apps in CarPlay, although there is no guarantee it will be honored it is good to file. Hopefully this helps.

For Notification Tones, Audio session category is configured to AVAudioSessionCategoryPlayAndRecord with VoiceChat mode and AllowBluetooth option. Tones play using system audio services without an active audio session. No background audio session activation occurs for notification tones. Are you talking about using AudioServicesPlayAlertSound()/AudioServicesPlaySystemSound()? If so, then the answer here is basically no, you can't change any of the details of how those APIs behave. Both of those APIs work by shifting the actual playback out of process, instead of having your app directly play the audio. This allows them to be used in apps that don't have ANY audio configuration at all, as well as in contexts that would otherwise be complex/problematic. For example, it lets apps with arbitrarily complex and configurable audio configuration play alert sounds without having to figure out how to mix and route that alert sound with their own dynamic configuration. It's true that AudioServicesPlayAlertSound() modifi
