Basic audio synchronization
I have an iOS music game (-ish) app that requires some basic synchronization between audio playback and other non-video events. To keep it simple, let's say I have some sound effects in files and I want to show a dot on the screen when a sound effect is played with a high degree of accuracy. Playing through the built-in speaker is fine, but users will often be using AirPods and the added latency is too noticeable. I don't need this to be super-low latency, I just need to know what the latency is so that I can show the dot exactly when the user hears the sound. I've mostly been experimenting in the AVAudioEngine/AVPlayerNode space. Those provide a variety of latency/ioBufferDuration properties (see below), but unfortunately they seem pretty inaccurate. Are they supposed to be? Is there a better way to sync non-video things with audio playback? func printLatencyInfo() { ttprint(audioSession.inputLatency: (audioSession.inputLatency)) ttprint(audioSession.outputLatency

SwiftUI Swipe to pop navigation
I want to hide the navigationbar in my swiftUI View and i can do that using the .navigationbarhiddent(true) but i still want to have the swipe to back functionality, i added my own button to dismiss the view but i couldn’t know how to add the swipe to back functionality. i stumbled upon this answer but it was not perfect because it applied to all the Views in my app, I want to be able to add it to only a the views of my choosing. extension UINavigationController: UIGestureRecognizerDelegate { override open func viewDidLoad() { super.viewDidLoad() interactivePopGestureRecognizer?.delegate = self } public func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool { return viewControllers.count > 1 }}

No sound or vibrations
My phone will not vibrate or have any sound. I can still talk to people on the phone, but I usually have to call them back because I didn't notice they called. I flip switch on side on phone.. Nothing happens. Can put headphones in and hear muffled sound. Anyone else having similar problems? I've tried restarting and nothing works. Ugh. I'm pretty sure it's an iOS 9 issue but it was not fixed in 9.0.1, hopefully it will be in 9.0.2 Let me know if I'm not alone I'm kind of freaking out and starting to think its my phone even tho the sound worked one minute and not the next without me doing anything to the phone. Thanks!

How to record audio played by the app
Hi all,I would like to know if it's possible to record all audio played by my app, either played via AudioUnit, AVPlayer, AudioQueue or some other source (except system sounds / sounds from other apps). The thing is that some of the audio played by the app is generated by code that resides in a static library, the source of which is hard for me to access. Thus I would like to achieve this by intercepting the mixed down audio from all sources before it leaves the app. I'm thinking in the way of setting up an AudioUnit and connecting it's input bus to the audio coming from the app, but I am not sure if this can work. I tried to setup a remoteIO audio unit, and getting the samples from the output callback sample buffers, but it does not work that way, only makes a very annoying noise, which is mixed with other app audio 🙂Thanks in advance for all your thoughts!

Analyzing Audio to Classify Sounds With Core ML
Hi, was following along with this documentation (https://developer.apple.com/documentation/soundanalysis/analyzing_audio_to_classify_sounds) trying classify sounds within my SwiftUI app. Here's what I have: let noiseDetector = NoiseDetector() let model: MLModel = noiseDetector.model let analysisQueue = DispatchQueue(label: com.apple.AnalysisQueue) public var noiseType: String = default class ResultsObserver : NSObject, SNResultsObserving, ObservableObject { func request(_ request: SNRequest, didProduce result: SNResult) { guard let result = result as? SNClassificationResult, let classification = result.classifications.first else { return } noiseType = classification.identifier let formattedTime = String(format: %.2f, result.timeRange.start.seconds) print(Analysis result for audio at time: (formattedTime)) let confidence = classification.confidence * 100.0 let percent = String(format: %.2f%%, confidence) print((classification.identifier): (percent) confidence.n) } func request(_ request: SNRe

synchronizing audio recording to playback
I am playing back audio on an AVPlayer while recording audio with AVAcaptureSession. How can I synchronize the recording to the audio playback timeline. I am subtracting both inputLatency & outputLatency from AVAudioSession to the timestamp of the capture audio but the timing seems to be still be off. What other latencies do I need to compensate for?

Notification Sound with iOS 17
Why did Apple change the sound for Notifications in iOS 17??? I just finally upgraded today from iOS 16.7.2 to iOS 17.1.1 and among other things I don't like, this one makes no sense whatsoever! Why can't user select the sound we want for Notifications? At least when I had the Tri-Tone sound I could hear it. The new sound is way too quiet, causing me to miss notifications now. PLEASE FIX THIS ASAP!

Alarmkit custom sound plays once
When setting a custom sound in AlarmKit, the alarm only plays the audio file once. I can understand why push notifications would play a sound only once, but I don’t understand why alarms can only play the sound for less than 30 seconds. We’re already at beta 6, so I’m wondering if Apple still hasn’t fixed this or if they have no intention of fixing it.
