    Just curious, what is your Managed Stripping Level set to? (Edit -> Project Settings -> Player -> Managed Stripping Level). These errors are generally caused by some code stripping issue. If you disable code stripping does your app work on iOS?

    Yep, it works. I know that disabling stripping is a potential workaround for this bug. But it has build size increase side effect. So it will be nice to see this bug fixed properly.

    Thanks for the bug report. I was talking about this one and it brought to my attention that some of this issue stemmed from an engine side problem that I believe was fixed (but maybe never backported). Is it possible for you to try updating your project to Unity 2019.3 or higher to test this?

    Team is looking to reproduce this on their end, and will roll out a fix as soon as they can.

    @TreyK-47 @DavidUnity3d Hello! Any updates?

    Unity 2020.1.2 with Addressable 1.8.4 - same issue.
    Found this on the forum https://forum.unity.com/threads/bug...produce-class-with-id-245-editorclass.769838/ maybe it can help.

    UPD:
    The issue occurs only with Strip Engine Code option on.

    UPD2:
    Managed to fix an issue by creating an AudioSource in the scene and referencing an audio mixer group in it.

    Tried to use link.xml but it didn't help. Maybe I've made a mistake in syntaxis...

    Code (CSharp):
    1. <!-- Doesn't work :/ -->
    2.    <assembly fullname="UnityEngine.AudioModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null">
    3.        <typename fullname="UnityEngine.AudioSource" preserve="all"/>
    4.        <typename fullname="UnityEngine.AudioClip" preserve="all"/>
    5.        <typename fullname="UnityEngine.AudioMixer" preserve="all"/>
    6.        <typename fullname="UnityEngine.AudioMixerController" preserve="all"/>
    7.        <typename fullname="UnityEngine.AudioMixerGroupController" preserve="all"/>
    8.        <typename fullname="UnityEngine.AudioMixerEffectController" preserve="all"/>
    9.        <typename fullname="UnityEngine.AudioMixerSnapshotController" preserve="all"/>
    10.    </assembly>

    Interesting, that seems like the same issue with the RuntimeAnimatorController (same fix).

    <assembly fullname="UnityEngine.AudioModule">
    <namespace fullname="UnityEngine.Audio" preserve="all"/>
    <!-- <type fullname="UnityEngine.Audio.AudioMixerSnapshot" preserve="all"/> -->
    </assembly>

    add this to link.xml is ok
    from the buildreport, The UnityEngine.Audio.AudioMixerSnapshot is the key
