Unity 2019.2.7 build iOS crashes in Shader Compile

Hi. I was trying to do a build with Unity 2019.2.7f2 and got some crashes in shader while doing a build for iOS:
Shader compiler: Compile Standard - FORWARD, Vertex Program: Internal error, unrecognized message from the shader compiler process. Please report a bug including this shader and the editor log.
Shader compiler: Compile Standard - ShadowCaster, Vertex Program: Internal error, unrecognized message from the shader compiler process. Please report a bug including this shader and the editor log.
Shader compiler: Compile Standard - FORWARD_DELTA, Vertex Program: Internal error, unrecognized message from the shader compiler process. Please report a bug including this shader and the editor log.

etc...
Should I use for iOS Color Space Gamma and inside autographs only Metal?

 

Same here...

crashes compiling shaders with those messages, or silent hang-ups during compiling shader variants.
It also crashes in 2019.2.8f1 + 2019.2.9f1

 

have same problem

 

Same here...

 

Same here...

 

Might help to mention that i´m working in macOS and i have also just upgraded to Catalina

 

Yes, I forgot to say this important information.
I have tested unity 2019.3 in CatalinaOS and might be solved this problem, but right now Unity Team are working in the issue about Catalina OS

 

I´m also working on 2019.3(beta) right now, since i need to publish an update asap. Shader compilation works indeed, But it brings a whole new bunch of issues to solve and building a prod app with a beta buildof unity seems flaky to say the least

 

Hey guys, I found a solution to this problem without upgrading to the beta

Just change the color mode to "Linear" from "Gamma"

 

My problem is when change from linear to gamma, also with linear you can't support opengl2 and alot of devices are using this library

 

Dear friends! This solution for Catalina OS works fine for me. Just replace UnityShaderCompiler file from 2019.3 beta to your 2019.2 (in my case 2019.2.9f1) Delete /Library folder and restart Unity

 

Thanks a lot! It’s working in my case!

 

Works for me too !

 

It works for me too.

 

It works for me too. Thank!

 

This solved my problem. Creating projects under 2019.3.0b10 works just fine too. Thanks a lot!

 

Didn't work for me. I still see the pink screen

 

Thanks for your workaround!

 

Great workaround, works like a charm!

 

Thank you for this solution. Shaders are back again.

 

Just remove Library Folder and Reimport Assets. it will resolve the pink screen issue.

 

In case If anybody is looking for UnityShaderCompiler From Unity_2019.3.0 BETA.
Here it is.

 

Replacing UnityShaderCompiler did help, thank you! And special thanks to @Nomibuilder for shared file, because it took some time before I could find it as I first found this solution in another thread.

 

Thank you very much!

 

This solved my problem too but I did notice a difference a difference in the splash screen between Unity 2019 2.12 with the 3.0 shader compiler and 2019 3.0. On the 2.12 with 3.0 compiler the splash started at around 50% bigger then shrunk to normal size while on 3.0 started and stayed at normal size. Not much of a difference but suggests there might be other problems using 2.x with the 3.0 shader compiler.

 

Same problem too, and i already overwrite de shader compiler, someone still have the problem?

 

Hey, just try to use Opengl3 first.
We change the graphics APIs to opengl3, and then the build is OK now!
We use 2019.2.15f on catalina.

 

Thank you so much, This has saved me so much time.

 

This worked for me too, macOS 10.15.2 and Unity 2019.2.5. Good find.

 

Where do I find the UnityShadeCompiler file for 2019.2? I am using 2019.2.16f1 and am having the Shader compiler problems.

 

@Nomibuilder and @agmaster - thank you for helping me into this
In Unity 2019.2.11f1 version, I was getting this problem and I got a solution after using your opinion.

 

I encountered this problem myself using 2019.2.15. Seems like it was properly fixed in 2019.2.17 invalidating continuing need for the compiler replacement workaround

 

Not working for me. No idea where Unity is installed on my Mac. Absolutely frustrating, guys. Please fix this.

 

yes, you are right complete frustrating - how this kind of mistake can happen that I can't able to understand!!!

 

Thanks man! Worked great for me!

 

Please tell the newbie which folder / Library should be deleted?

 

I'm stumped as well. I can't find this folder on my Mac. I can't get into the Unity part of the URL - it just opens Unity.
[EDIT] Found out how to show the contents on Unity - Right click on it and click on Show Package Contents.

 

FYI, I started using a new version of Unity, and the problem went away. I
1. Did an export of my entire project
2. Made a brand new Unity project with the latest version of Unity.
3. Imported my project into the newer version build.
