When i run a unity game in xcode i got the following error

"UnityPause(bool)", referenced from:
  -[EtceteraManager showViewControllerModallyInWrapper:] in    EtceteraManager.o
  -[EtceteraManager dismissWrappedController] in EtceteraManager.o
  -[EtceteraManager showAlertWithTitle:message:buttons:] in EtceteraManager.o
  -[EtceteraManager showPromptWithTitle:message:placeHolder:autocorrect:] in EtceteraManager.o

  -[EtceteraManager showWebControllerWithUrl:showingControls:] in  EtceteraManager.o
  -[EtceteraManager popoverControllerDidDismissPopover:] in      EtceteraManager.o

ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) How can i solve this error?

Answer 1

Please check whether library containing EtceteraManager class is linked with your project. If yes then check for architecture of library using file command on terminal.

file $PATH_TO_LIB

The architecture should be same as on project's architecture settings.
