In the below code AudioKit.start() crashes on my iPhone SE with iOS 10.1.1. It works fine on the Simulator.
private func play(note: Int) {
let pluckedString = AKPluckedString()
AudioKit.output = pluckedString
AudioKit.start() // <-- Crash here!
let frequency = note.midiNoteToFrequency()
pluckedString.trigger(frequency: frequency)
}
The console error log is

What have I missed? I can't find any documentation about any needed extra setup for devices compared to the simulator. The version of AudioKit is 3.5. XCode version is 8.1
I found the issue. I had a recording category set for the audio session. By making sure that the audio session category isn't AVAudioSessionCategoryRecord on playback; my app doesn't crash anymore.

I'm trying to test AVAudioEngine, watched the WWDC conferences about it, and did everything by the book to try to play a simple file.
Despite everything being exactly the same as in the samples that I found (WWDC and a few other places), despite everything seeming fine (no error, seems to be running), I have no sound output.
Here's the code:
NSError *error = Nil;
[AVAudioSession.sharedInstance setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionMixWithOthers error: &error];
[AVAudioSession.sharedInstance setActive:YES error:&error];
AVAudioEngine *engine = [[AVAudioEngine alloc] init];
AVAudioPlayerNode *player = [[AVAudioPlayerNode alloc] init];
[engine attachNode:player];
NSURL *fileURL = [[NSBundle mainBundle] URLForResource:#"piano" withExtension:#"wav"];
AVAudioFile *file = [[AVAudioFile alloc] initForReading:fileURL error:&error];
AVAudioMixerNode *mainMixer = [engine mainMixerNode];
AVAudioOutputNode *outputNode = engine.outputNode;
[engine connect:player to:mainMixer format:file.processingFormat];
[engine connect:engine.mainMixerNode to:outputNode format:nil];
[engine prepare];
if (!engine.isRunning) {
if (![engine startAndReturnError:&error]) {
//TODO
}
}
[player scheduleFile:file atTime:nil completionHandler:nil];
[player play];
NSLog(#"Engine description: %#", [engine description]);
Here's the output of the log call:

I have no idea how to diagnose this and can't find any mistake or reason for which this would not work.
Any idea?
Keeping the question in case anyone has this problem: as I was testing, all my variables were local variables in a test method, and as soon as the method was finished it was probably GC by ARC or something.
Having the AVAudioEngine variable outside (keeping a reference to it) fixed it.
I've got crash with this code
// ViewController.swift
import UIKit
import AVFoundation
class ViewController: UIViewController {
var engine:AVAudioEngine!
var EQNode:AVAudioUnitEQ!
override func viewDidLoad() {
engine.reset()
let Format = engine.inputNode.outputFormat(forBus: 0)
print("channelcount:",engine.inputNode.inputFormat(forBus: 0).channelCount)
//----->Start CRASH App stoped here
engine.connect(engine.inputNode, to: EQNode, format: Format)
engine.connect(EQNode, to: engine.mainMixerNode, format: Format)
var error: NSError?
engine.prepare()
print("done prepare")
do {
try engine.start()
} catch {
print(error)
}
print("done start")
}
}
And if I change Format to nil it make my app not working but not crash.
All of this work perfectly fine on Xcode simulator with no error.
But in the real iOS device (I use iPad 2019) test it crash.
Detail about my app: Live microphone adjust in Equalizer and display Equalized sound real-time.

I found the answer for this it nothing about formatting causing this error.
Check it out on my other question it fixed.

I am developing a VoIP application using Pjsip in Objective-C.
I want to try and integrate CallKit but I got an error on configureAudioSession. I copied AudioController.h and AudioController.mm from SpeakerBox from Apple into my project.
And I added this code :
AudioController *audioController;
- (void)configureAudioSession {
if (!audioController) {
audioController = [[AudioController alloc] init];
}
}
- (void)handleIncomingCallFrom:(NSString *)dest {
CXCallUpdate *callUpdate = [[CXCallUpdate alloc] init];
[callUpdate setLocalizedCallerName:dest];
[callUpdate setHasVideo:NO];
CXHandle *calleeHandle = [[CXHandle alloc] initWithType:CXHandleTypeGeneric value:dest];
[callUpdate setRemoteHandle:calleeHandle];
[provider reportNewIncomingCallWithUUID:[NSUUID UUID] update:callUpdate completion:^(NSError *error){
[self configureAudioSession];
}];
}
Phone is ringing, I can handle the call but it crashes whenever I answer. I receive this error :

Can you tell me how can I integrate Callkit?
This bug causes by you forget to add the Mircophone description in your Info.plist.

Im trying to make sure my app works on IOS. And doing so by trying to launch it to a IPhonesimulator on my mac.
doing:
./gradlew ios:launchIPhoneSimulator
Makes my app start on the simulator, the standard splashscreen by libgdx appears and then it shuts down and nothing more happends.
But when I build it ./gradlew ios:build ios:launchIPhoneSimulator I get these errors:

You simulator's audio output is borked. The openal audio toolkit is failing init which is causing everything to crash.
