AVAudioPlayer (AVFoundation) compile errors

[cre8ivepark]

I am using this code below to play simple audio clip. When I compile this, I got the error messages below.

NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource:@"clapping01" ofType:@"mp3"];
NSURL *backgroundMusicURL = [NSURL fileURLWithPath:backgroundMusicPath];
self.backgroundMusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:nil];
self.backgroundMusicPlayer.delegate = self;  
self.backgroundMusicPlayer.numberOfLoops = -1;  

[self.backgroundMusicPlayer prepareToPlay];

@cre8ivepark can you please verify if this still happens in the latest release? We had an incorrect project dependency in AutoToolbox that may be the root cause. Also, can you paste the imports in your source code if this still repros?

@cre8ivepark thanks for sending the code snippet. The issue is reproducible when importing <AVFoundation/AVFoundation.h> from a .m file. It would compile fine in a .mm file (because the header and dependencies were using C++ constructs). Fix is on the way.
