AVAudioPlayer not playing recording made with AVAudioRecorder

This may be a really simple problem but I've made a recording using AVAudioRecorder, then I stopped the recorder. After stopping the AVAudioRecorder, I press another button to play the recording but it doesn't play. The file exists, I can play it on my computer, even the code knows it exists, there is no error, but refuses to play. What can be the issue?

NSError *error = nil;
    if ([[NSFileManager defaultManager] fileExistsAtPath:[self.recorder.url path]]) {
        self.recordingPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:self.recorder.url error:&error];
        self.recordingPlayer.delegate = self;

        if (error) {
            NSLog(@"error: %@", [error localizedDescription]);
        } else {
            [self.recordingPlayer play];
        }


    } else {
        NSLog(@"Recording file doesn't exist");
    }

EDIT: just tried it on my device and it works fine, plays the recording. It just doesn't work on iOS simulator

The problem was with my record settings, I had the number of AVNumberOfChannelsKey set to 2, for some reason iOS simulator didn't like this, but iPhone was fine with it. Either way, my recording shouldn't have 2 channels in the first place, so good thing I spotted this.

NSDictionary *recordSettings = [NSDictionary dictionaryWithObjectsAndKeys:
                                    [NSNumber numberWithInt:AVAudioQualityMax], AVEncoderAudioQualityKey,
                                    [NSNumber numberWithInt:16], AVEncoderBitRateKey,
                                    [NSNumber numberWithInt:1], AVNumberOfChannelsKey,
                                    [NSNumber numberWithFloat:44100.0], AVSampleRateKey,
                                    nil];
