building rn project on ios fails with: No matching function for call to 'objc_msgSend'

[macrozone]

i could successfully export the unity project, but building the react-native ios project fails with "No matching function for call to 'objc_msgSend'"

What is your unity project? First step, It is recommended to use Cube instead of.

@f111fei i used an own simple one.

I figured out, that this only happens on the simulator. It works on a device

Had the same problem, switching Enable Strict Checking of objc_msgSend Calls to No in Build Settings fixed the problem.

@f111fei If I try to run the project on the device I get the following error:

▸ Compiling RCTBundleURLProvider.m

@nmsdvid 's solution caused 201 errors in my XCode project 🙃 Still haven't tried in a real device yet

Followed your steps but unable to run project in iOS. 😕
