Issue Statement

iOS Resolver library cannot be loaded in Unity 2021.1.11 and 2021.1.12. (Did not test 2021.2.0 beta yet). It can be loaded properly with Unity 2021.1.10.

After importing EDM4U, Unity logs an error like:

Assembly 'Assets/ExternalDependencyManager/Editor/Google.IOSResolver_v1.2.165.dll' will not be loaded due to errors:
Assembly name 'Google.IOSResolver' does not match file name 'Google.IOSResolver_v1.2.165'

And iOS Resolver is not loaded, verified through the absence of Assets > External Dependency Manager > iOS Resolver menu item. The odd thing is that all the other libraries, ex. Android Resolver, Version Handler, are loaded with no issue.

The same issue has been reported on Unity forum here

This seems to be a regression introduced in Unity 2021.1.11 as documented in the release note.

• Scripting: Editor logs an Error whenever the filename of an assembly does not match its name. (1109539)

Workaround

Since the issue is the mismatched library name, a simple workaround is to rename the dll file.

For instance,

• Rename Assets/ExternalDependencyManager/Editor/Google.IOSResolver_v1.2.165.dll to Assets/ExternalDependencyManager/Editor/Google.IOSResolver.dll
• Rename Assets/ExternalDependencyManager/Editor/Google.IOSResolver_v1.2.165.dll.meta to Assets/ExternalDependencyManager/Editor/Google.IOSResolver.dll.meta
• Rename Assets/ExternalDependencyManager/Editor/Google.IOSResolver_v1.2.165.dll.mdb to Assets/ExternalDependencyManager/Editor/Google.IOSResolver.dll.mdb
• Rename Assets/ExternalDependencyManager/Editor/Google.IOSResolver_v1.2.165.dll.mdb.meta to Assets/ExternalDependencyManager/Editor/Google.IOSResolver.dll.mdb.meta

After the renaming, Unity should be able to load iOS Resolver library properly.

However, there is a caveat: After renaming, Version Handler will no longer able to manage those files. That is, when a newer version of EDM4U is installed, Version Handler will not be able to automatically remove the older version of iOS Resolver.

The workaround is to remove the entire folder of Assets/ExternalDependencyManager/ folder before upgrading.
