Unity IAP - xcode Apple Mach-O Linker (Id) Error

Hi.
After adding Unity IAP I am getting Apple Mach-O Linker (Id) Error (detailed errors in attached file).
I also have Apple watch kit plugin and beHealthKit plugin inside project which might contribute to the problem.

Using Unity 2019.4.8f1
XCode Version 11.7 (11E801a)
iOS 11.0
WatchOS 3.1

Thank you!

Please compare to a new project without the mentioned components to narrow it down. We would need specific steps to reproduce on a new project.

Xcode compiles with only IAP. Problem arrises when combining with those plugins. I am not sure which one is the problem.

Understood, you’ll need to find out which one. Unfortunately it will likely take trial and error to determine.
