Compiling crash with swift 5.6

[rickytribbia]

Description

Hi all, thanks for your great work.
We're developing an app that use TwilioVoice and we deploy this app many times in previous months; it has already voice functionality like make/receive voip calls between different user (client)
In these days, indeed, we couldn't archive successfully our app and it seems to be caused by something related to your sdk and latest swift version; I hope to be wrong: in this case I need your help to check it out.

Important: when we build the app in debug mode (for example for development purpose using simulator or phisical device) we haven't any issue and it builds always successfully.

Steps to Reproduce

1. Archive an app with TwilioVoice that set audioDevice.block with DefaultAVAudioSessionConfigurationBlock

Code

As your sample in our application we have:

// The mode set by the Voice SDK is "VoiceChat" so the default audio route is the built-in receiver. Use port override to switch the route.
audioDevice.block = {
    DefaultAudioDevice.DefaultAVAudioSessionConfigurationBlock() // it seems to be the incriminated line.
    
    do {
        if toSpeaker {
            try AVAudioSession.sharedInstance().overrideOutputAudioPort(.speaker)
        } else {
            try AVAudioSession.sharedInstance().overrideOutputAudioPort(.none)
        }
    } catch {
        NSLog(error.localizedDescription)
    }
}

audioDevice.block()

Expected Behavior

We expect to archive the app successfully like previous times 😅

Actual Behavior

❌  error: Abort trap: 6 (in target 'Moolti' from project 'Moolti')



❌  error: backend command failed due to signal 6 (use -v to see invocation)

🤩 🤩 🤩

Thank you

Hi @bobiechen-twilio any update?
We've tried to reproduce the issue trying to archiving your quickstart project and it happens.
I see that in this repo there is also already the same issue

[rickytribbia]

Hi, we've an app release waiting to resolve this archiviation issue. Has anyone found a solution or a workaround for this?

[michaelmoneypenny]

This sounds very similar to an issue we're having in our build pipeline when switching to Xcode 13.3 / 13.3.1
The only stable version so far is up to 13.1

LLVM ERROR: out of memory

@michaelmoneypenny @rickytribbia I am having the same exact issue when trying to archive my project. It runs fine when I build and run on a device but when I archive it gives me Abort Trap 6 with same stack trace. I found a fix by going into Build Settings > 'Enable Bitcode = No'. Not sure if enabling bitcode affects functionality but it let me archive after setting it to NO.

Thanks Isitar, I have read that this is a bitcode issue - if the issue keeps hanging around I will have to disable bitcode. I don't think it will affect functionality, from my very basic understanding it trims the size of your app and allows apple to re-optimise by device it when it reaches the App Store

[bobiechen-twilio]

Hi and hope everyone is doing well.
It seems that this issue is no longer reproducible on Xcode 13.4 and Xcode 14 beta.

[michaelmoneypenny]

Hi @bobiechen-twilio I'll try updating our build machine and see what happens, thanks :)
