I recently ran into a problem that I couldn't find discussed anywhere on the internet - I was initializing an AVAudioPlayer
to play an audio file, and getting the following error:
Error Domain=NSOSStatusErrorDomain Code=-50 "Operation could not be completed. (OSStatus error -50.)
As it turns out, I had made a mistake creating my NSURL
to send to the audio player init
method, resulting in the NSURL
object being null. Stupid mistake, pretty easy to find when debugging, but I thought I'd list it here just in case someone else does the same thing.
“ OSStatus error -50” means paramErr
, an old-style Mac error code indicating a bad parameter.
