Just bumped into this issue today too!

I’m not sure what caused the problem, but I have a feeling it might be something to do with Unity’s change in 2019.3 which packages things up into UnityFramework within the XCode project… but basically, it’s the Locale.h file within this project which is causing the issue. It’s conflicting with the system <locale.h> library and causing all these linker issues.

The simple fix is to rename Locale.h, Locale.mm (and the reference to Locale.h within Locale.mm). I renamed them to LocaleTools.h / LocaleTools.mm (no need to rename the class) and everything seems to have now built correctly within XCode. 😃

This thing broke my project too. Now I am finding a way to remove it from unity. Any way to do it?

if you don’t want a location functionality then just remove it from plugin >> iOS >> location related .a file

and remove or comment code where applicable … simple !!
