I feel that IOS18 camera filters are over complicated and generate lower level results than iOS18 filters. I am really missing the Vivid filter. It was perfect on ios17.

Hi community, I'm trying to setup an AVAudioFormat with AVAudioPCMFormatInt16. But, i've an error : AVAEInternal.h:125 [AUInterface.mm:539:SetFormat: ([[busArray objectAtIndexedSubscript:(NSUInteger)element] setFormat:format error:&nsErr])] returned false, error Error Domain=NSOSStatusErrorDomain Code=-10868 "(null)" If i understand the error code 10868, the format is not correct. But, how i can use PCM Int16 format ? Here is my method : - (void)setupAudioDecoder:(double)sampleRate audioChannels:(double)audioChannels { if (self.isRunning) { return; } self.audioEngine = [[AVAudioEngine alloc] init]; self.audioPlayerNode = [[AVAudioPlayerNode alloc] init]; [self.audioEngine attachNode:self.audioPlayerNode]; AVAudioChannelCount channelCount = (AVAudioChannelCount)audioChannels; self.audioFormat = [[AVAudioFormat alloc] initWithCommonFormat:AVAudioPCMFormatInt16 sampleRate:sampleRate channels:channelCount interleaved:YES]; NSLog(@"Audio Format: %@", self.audioFormat); NSLog(@"Audio Player Node: %@", self.audioPlayerNode); NSLog(@"Audio Engine: %@", self.audioEngine); // Error on this line [self.audioEngine connect:self.audioPlayerNode to:self.audioEngine.mainMixerNode format:self.audioFormat]; /**NSError *error = nil; if (![self.audioEngine startAndReturnError:&error]) { NSLog(@"Erreur lors de l'initialisation du moteur audio: %@", error); return; } [self.audioPlayerNode play]; self.isRunning = YES;*/ } Also, i see the audioEngine seem not running ? Audio Engine: ________ GraphDescription ________ AVAudioEngineGraph 0x600003d55fe0: initialized = 0, running = 0, number of nodes = 1 Anyone have already use this format with AVAudioFormat ? Thank you !

Is anyone developing a way for users to control an iOS or PadOS device playing Apple Music to a DAC via USB to amp from another iOS or PadOS device wirelessly? Specifically, full control. Not Accessibility, not to Apple TV, not HomePods, not firmware downgraded Airport Expresses to a DAC or other hacks mentioned for the past decade this “connect” like feature has been desired by audiophiles seeking exclusive mode on a device with that (iOS/PadOS) but — control it while sitting on a couch or in a wheel chair across the room. Exclusive mode being the key feature iOS and PadOS offer that is desired with full or nearly full Apple Music control.

I am a developer working on iOS apps. In the demo, I planned to replace the local images with Heic format instead of PNG format, but the actual test results showed abnormalities on this device, while the other test devices displayed normally Heic images are converted by the built-in image conversion function on Mac. I tested multiple Heic images, but none of them were displayed and the image information returned nil,,but PNG images can be displayed normally. device information:

I’m working on real-time object detection using YOLOv8, but I only need to detect objects in approximately 40% of the screen area. Is it possible to limit the captureOut method to focus solely on that specific region of the screen? If this isn’t feasible, I’m considering an approach where the full-screen pixel buffer is captured and then cropped to the target area before running detection. However, I’m concerned about how this might affect real-time performance. I’d appreciate any insights on how to maintain real-time performance or suggestions for better alternatives. Thank you!

I am currently developing an application that requires access to GPS coordinates from photos on iOS. However, with the recent update to iOS 18 beta, I have encountered a challenge: I can only view photos within maps, and I am unable to access the GPS coordinates directly. Could you please provide guidance on how to enable or retrieve GPS coordinates from photos in the current iOS 18 beta version? Any insights or resources you could share would be greatly appreciated. Thank you for your assistance!

Hello, I’ve encountered an issue where a green line appears only in the thumbnail view of an image in the iPhone photo gallery. The green line is not present in the actual image itself. Here are some additional details: • The issue occurs only when saving the image as a JPEG. When saved as PNG, the green line does not appear. • The green line also shows up when using the PHAsset method requestImage(for:targetSize:). Depending on the targetSize, the resulting image may contain the green line. • Interestingly, this issue does not appear on iPhone Xs Max running iOS 15.2.1. However, the green line does appear on iPhone 15 Pro Max running iOS 18.0.1 when viewing the same image. I have attached the problematic image for your reference. Following images are the screen captures that shows the issue occurring on my iPhone. iPhone 15 pro max (iOS 18.0.1) iPhone Xs Max (iOS 15.2.1 ) Could this be related to a display or gallery app issue on iOS? Any advice or solutions would be greatly appreciated. Thank you!

I’m currently working on an iOS project that involves loading and playing stereoscopic/spatial videos. I’m using the AVFoundation framework, specifically AVURLAsset, but I’m having trouble determining how to correctly load and handle stereoscopic videos. I would like to know: Any guidance or code snippets would be greatly appreciated, I´m not understanding pretty well the apple developer videos... Thank you in advance for your help! Best, Lau

I'm using PhotoKit in macOS to add photos to the user's library. Experimenting with Shared Photo Library, it seems that these new photos always end up in the Personal Library, not the Shared Library. I'd like to get them into the Shared Photo Library somehow. Is this possible? Things I've considered: A variation/option for PHAssetChangeRequest.creationRequestForAsset: doesn't seem to exist A property of PHAsset: can't find anything A special PHAssetCollection that I could add to: again, doesn't seem to exist

I cannot mirror or extend my screen from mac mini m2 to iPad 10 gen. Whenever I click on "mirror or extend screen" my external display for mac refreshes after showing "no signal" and comes back on meanwhile my iPad locks out and screen mirror or extending is unsuccessful. But I can mirror my iPad screen to mac mini m2. Earlier everything was working, suddenly it is not working

At Apple Developer documentation, https://developer.apple.com/documentation/avfoundation/avcapturedevice/discoverysession you can find the sentence You can also key-value observe this property to monitor changes to the list of available devices. But how to use it? I tried it with the code above and tested on my MacBook with EarPods. When I disconnect the EarPods, nothing was happened. MacBook Air M2 macOS Sequoia 15.0.1 Xcode 16.0 import Foundation import AVFoundation let discovery_session = AVCaptureDevice.DiscoverySession.init(deviceTypes: [.microphone], mediaType: .audio, position: .unspecified) let devices = discovery_session.devices for device in devices { print(device.localizedName) } let device = devices[0] let observer = Observer() discovery_session.addObserver(observer, forKeyPath: "devices", options: [.new, .old], context: nil) let input = try!

Hi: I am working with the ObjectCapture frameworks and sample code. Everything works great. We are trying to go from capturing 12MP images as in the sample code to capturing 48MP 6048 × 8064 images. We can't seem to get it to work. Any advice here?

This ideal gonna be cool: When people finish recording a video and later realize there's something else worth capturing, they can only create a second clip. But what if it were possible to reopen the first video and continue recording from where they left off? This would be a great convenience for many people

With iOS 18.1 having call recording out of the box, is it now possible to build apps that can record calls? I could not find anything in the swift ios docs yet.

I'm seeking information about the original file schema for an m4a file recorded directly on an iPhone (iPhone 5 running iOS 9.2.0). I currently have two files from which I extracted metadata using ExifTool. The first file was provided to me by someone who claims it was recorded on an iPhone 5 with iOS 9.2.0. I would like to verify whether this file has been edited. File Permissions: -rwx------ Content Create Date: 2016:03:01 14:21:08+07:00 The second file was recorded by me on the same device model and iOS version. File Permissions: -rw-r--r-- Date/Time Original: 2024:10:03 11:44:16+07:00 As you can see, the file permissions differ, and the key for the recording date also differs: one uses "Content Create Date" while the other uses "Date/Time Original." I would like to determine if the first file was edited, but I haven't been able to find any official documentation on the m4a schema or metadata structure from audio recorder apps. I reached out to support, and they directed me to this forum. Any insights or help would be appreciated.

Hello developer community. I purchase recently my new iPhone 16 Pro Max; it is a premium device with great quality overall. However, I am having a big trouble shotting in ProRaw MAX (48 mode) with native camera. Just to be clear, the problem that i will describe do not happen in 3rd apps, such as ProCam; only with native camera. When I use ProRaw Max, and take the photo, and watch the photo in the gallery the image can’t load and render properly. Even, when I maximize the image to the maximum I can see pixelated portions, defects and super low resolution and excessive denoise. For comparison, this not occur with my previous iPhone 15 PM and/or when I capture photos from ProCam (same settings and configurations) in the 16PM. I proceed to take the photo, open the gallery and I see full of details, when zoomed to 100%. I tried to format the phone, reinstall the software via my mac. Tried even to look at some forums to find if there’s someone with the same issue, the information available so far is very low. I’m in contact with apple assistant from my country (Portugal), and they escalated this problem to the engineers. (that’s what I’ve been told). They did all the tests remotely (via analysis and improvement’s) and they told me that my phone is perfect in the hardware department. I will wait for the next days to be contacted again. I’m on iOS 18.0.1. (The last software available at this time). I tried multiple 16PM, from friends, family and stores (more or less 10 units), and they all showed the exact same problematic. I’m a professional photographer, so I find this frustrating and unacceptable. I would appreciate any additional suggestion or information. Thank you! Cannot add photos or files because they are bigger than 5Mb.

Currently we tested iOS AAC LC encoder using AudioToolbox framework, no matter we set mManufacturer to kAppleHardwareAudioCodecManufacturer or kAppleSoftwareAudioCodecManufacturer, it always run on CPU.
