Unity Engine

Unity 2021.3.19f1 does not b build for iOS. I get over 100 errors, some of which are:

I could go on, but I think I’ve made the point. Something is very, very wrong with the iOS module for this version of unity.

Delete the Library folder, then when you open the project it will reimport everything and it might be better

Thanks, that worked; it drives me nuts that Unity still requires us to manually manage their own automated folders.

It’s usually when a unity version or package is updated, or a project is shut down unexpectedly
