Could not produce class with ID 91 - iOS

I receive this error when loading my asset bundle. Does anyone know what class ID 91 corresponds to?

It is not listed in the class ID reference page.

http://docs.unity3d.com/Manual/ClassIDReference.html

 

AnimatorController? As in, UnityEditor.UnityEditorInternal.AnimatorController? That doesn't sound like something that should be getting included in my asset bundle...

 

hello,"Could not produce class with ID 90",i can't find the ID(90) in "http://docs.unity3d.com/Manual/ClassIDReference.html", Can you help me? Thanks!

 

Excuse me, are you solve the problem, i get the same quesion

 

When I upgraded the version to unity5.0.0f4, I found it works on iOS. But for some reason, I upgraded the version to Unity5.0.0p3, it dosen't work. It is weird.

 

it is stripping level cause this question , i choose the level "strip ByteCode", but AnimatorController is in UnityEditor.UnityEditorInternal, i can't use in the Scripts, So i think it is stripped from my ipa.And i don't anderstand why AnimatorController will produce in the Scripts.

 

It sounds the key point, i will try it.

 

if you solve the problem, please tell me how to do that, thanks

 

two methods:
1. set the stripping level "Disabled" , it can be solved. it means AnimatorController would be stripped, if the stripping level is "strip ByteCode".
2.using a blacklist for stripping. if you use the first method, the executable will become bigger than before. I'm trying.

 

thanks, i know this methods, but i must use "strip ByteCode" , because in IOS, use this level will let your code hard to decompile. And blacklist can't help in this problem, because AnimatorController is in UnityEditor.UnityEditorInternal, but you can't add UnityEditor.dll to the blacklist.

 

Hi guys, did you manage to find out how to solve this problem ?
I get the same error but with Could not produce class with ID 159. (159 is EditorSettings). And this cause XCode debug to crash due to EXC_BAD_ACCESS. (Screenshot).
Unity version : 5.0.1f and 5.0.1p3 all gave me the same problem. Reinstallation doesn't help either. This is really headache.

This seems to be so random, because just yesterday it was running fine. I didn't change anything in the project except delete some objects from the scene.

 

Oh, i solve my problem, because i use AnimatorController in the 3d model, And i pakage it in the assetbundle, so when i build the ipa pakage, AnimatorController will be strip, and when i load the assetbundle, I receive this error (could not produce class with id 91), and just not put the model into assetbundle it will be slove(have one model not put into is enough)

 

That means you make a assetbundle of AnimatorController and keep your model as Asset.

 

Make sure your code without any reference of EditorSetting.

 

Is there a way to do that ? I have no clue.
I use Find references in Mono Develop to look for usage of EditorSettings but nothing coming up.

 

Leave a empty AnimatorController file in Resources folder.
And then problem is solved. ^_^

 

I think I managed to resolve this by adding 'UnityEngine.RuntimeAnimatorController' to my link.xml

 

when i upgrade to Unity5.1.2f1 build ios show this error too..

 

I have it problem too on Unity5.1.3f1

 

The link.xml suggestion wasn't working me, but bolang's suggestion of an empty AnimatorController worked like a charm. I'm running Unity 5.1.2f1.

 

I'm getting this with class 199 in Unity 5.2.1p2..

 

Hi,

We faced the same issue, the Resources trick works. But I was wondering : Why we can't add the UnityEditor assembly to the link.xml, can someone from UnityTechnologies know ?

I tried UnityEditor, UnityEditor.Animations, nothing works.

Thanks.

 

Is this a serious answer? I touch an empty file (with no suffix or with .txt) AnimatorController in Assets/Resources/ but nothing happened. I'm using Unity 5.3.0f4.

 

Both the Resources trick and link.xml not working for me with unity 5.3.0f4. But disable Strip Engine Code working. Did anyone have another solution without disable strip engine code??? Please help!!!

 

Currently it's almost compulsory to use IL2CPP instead of Mono as the scripting back end (iOS), and this should be fixed and clarified ASAP, as many a developer relies on Unity 3D.

 

Hi folks, I'll try putting an empty AnimatorController in the Resources folder.

But is there a more elegant way already?

 

We have the same problem in 2018.4.0f1.

Workaround with empty AnimationController works, but we dont use Resource folders, so its not optional.

For this reason I reported as bug under 1156093.

I attached example of empty AnimationController file for others.

 

We have the same problem in 2018.3.14f1.

 

Have the same problem with Unity 2019.2.17f1. The problem appears when I added Addressables to existing project: one of my bundles contains Prefab with Animator and few with Animation Components. I tried:
1. Add link.xml to Assets - doesn't work;
2. Add Animator / Animation Components to the built-in scene - doesn't work
3. Add Prefab with Animator / Animation Components and save it to Resources Folder - doesn't work
4. Disable Strip Engine Code - the only working solutions but it adds 12 Mb to my apk file which is absolutely inappropriate as I added Addressables to decrease apk size, not to increase

The bug introduced in Unity 5 and lives long and happy life

 

Any solution?
Or the only solution is disable strip engine code?
I have this problem with the addressable

 

At the end I finished with this: added empty object to the very first scene with Animator and Animation, in this case Unity doesn't strip the animation component
