Xcode16 Symbol not Found: `__ZN5swift39swift51override` with compatibility flag

I am receiving runtime Symbol not Found errors that start with __ZN5swift39swift51override. I found and am trying to use the -lswiftCompatibility50 and -lswiftCompatibility51 flags. That appears to have gotten rid of the issue with a swift50override symbol, but no matter what I do, I cannot get rid of the swift51override symbol issues.

My issue is very close to the one described here: ios - Flutter Xcode 16 undefined symbols error? - Stack Overflow
