What should I do if the project reports an error "nil string parameter" when setting the doorbell device?

The Xcode output log is as follows:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:]: nil string parameter'
The reason: It is due to the absence of an audio file
Solution: You need to add a short audio file named tywarning.caf to the root directory of your main project.
