It seems there is a problem here with the PlaySoundFileNamed action we put in the cat’s mouth animation. I just realized that the sound does play, but only once and it raises an error:
2016-10-27 15:11:09.183 CatNap[2833:357462] SKAction: Error playing sound resource
how can this be happening since it’S not coming from my code, but from the XCode editor?
Thanks in advance
Compare with the final sample code and files for the chapter.
i have the same problem, even when i run the sample code
It looks like a Xcode bug since it’s in an action loop made in the editor and not by code… I’ll try contacting apple about that.
I have the same problem 
I have experienced the same problem too.
I have the same problem. I tried moving mrreow.mp3 outside of ‘Sounds’ folder and then it works.
I’ll give it a try! Thanks for the solution even if it’s kind of a weird one!
