    Unity Version : 2021.3.3f1
    XCode Version : 13.2.1

    I know this error is because these function was undefined. But it built successed by using Unity2019.4.16f1. And they also not be used or referenced. I wondering there is an option to setting "do not build undefined function" in xcode.

    Ok, I found the answer myself

    The key issue was from here: "Project Settings - Player - Optimization - Strip Engine Code - Managed Stripping Level"

    There are only 'low medium high' three options in Unity2019. But they add a 'minimal' option in Unity2021 !

    The lowest enum value is 0 represents 'low' in unity2019. But unity won't change it automatically in Unity2021, which is still 0, but represent 'minimal', and has a different mean.

    So I changed it to "low", and solved my problem.

    Hi,

    Thanks for reporting this. Our goal was that projects created prior to 2021.3 retain their Managed Stripping Level values. I poked around and found a bug that is likely what you encountered.

    The Managed Stripping Level value is not stored in the project until it is changed from the default value. This means that a project that never changed from the default value will continue to have the managedStrippingLevel value serialized as empty. When the project is opened in 2021.3 or newer, the Editor sees an empty managedStrippingLevel and initializes with the default value, which starting with 2021.3 is now Minimal.

    We'll take care of getting this fixed.

    As you found out, the workaround is to change the value back to `Low`.

    Thanks,
    Mike
