iOS Code to Convert m4a to WAV

Question

Does anyone have any code snippets that show how to convert an M4a file to WAV? I know there are libraries that convert the other way around.

Thanks.

Here is an edit to @O2U answere. As above code does not actually convert it to wave file. Please use "kAudioFileWAVEType" instead of "kAudioFileCAFType" in above code at line //Create destination file ExtAudioFileCreateWithURL(destinationURL, kAudioFileCAFType, &dstFormat, nil, AudioFileFlags.EraseFile.rawValue, &destinationFile)
