Question Unable to build [UnityEditor.dll assembly is referenced by user code]

UnityEditor.dll assembly is referenced by user code, but this is not allowed

When building the apk, I am getting this error,

Which script reference to it, how can I know it?
There are a lot of script that contains using UnityEditor

 

You can't use that namespace in a build.

Use conditional compilation to remove it (AND remove all the code that uses that namespace obviously).

Code (csharp):

1. #if UNITY_EDITOR
2.  using UnityEditor;
3. #endif

OR...

Put the file into an

Editor

folder.

 

Hey so I've been running into the same error and tried updating to current 2022.1.16f1 to see if any of those IL2CPP fixes since 1.11 covered it - I also boxed out 120 different scripts with conditional compile. No dice. Not sure what else I could check on when trying to build to iOS.

 

Here's a log I'm getting from an attempted iOS build with the same error:

Doesn't tell me too much about what stopped it, unfortunately

Start bisecting. Delete HALF the code, patch over the bleeding. Same error? Restore that code, delete the other half.

Lather rinse repeat until you find the problem code. Bisecting works FAST, as powers of 2 are extremely ... powerful.

Obviously I'm assuming you're using source control properly so restoring code is one click.

 

Good idea. Thanks Kurt.

 

figure it out?

 

Try to build with Managed Code Stripping disabled. You have to switch to Windows Mono scripting backend for that. If it succeed it can be related to this Unity bug:
https://issuetracker.unity3d.com/is...ue-to-unityeditor-dot-dll-usage-in-testrunner
It was fixed in 2023.1.0a23, but not for other versions yet:
IL2CPP: Fixed scenarios where assemblies that were excluded from player builds could be pulled in during managed code stripping. (UUM-14403)

In this case vote for the fix.
