I forgot to mention the current code (void)setupNativeScanner {    AVCaptureSession* captureSession = [[AVCaptureSession alloc] init];    self.session = captureSession;    AVCaptureDevice *captureDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];    self.device = captureDevice;    NSError *error = nil;        self.input = [AVCaptureDeviceInput deviceInputWithDevice:captureDevice error:&error];    if (self.input)        [_session addInput:_input];    else        NSLog(@"Error: %@", error);        AVCaptureMetadataOutput *captureMetadataOutput = [[AVCaptureMetadataOutput alloc] init];    [captureSession addOutput:captureMetadataOutput];    self.output = captureMetadataOutput;        dispatch_queue_t dispatchQueue;    dispatchQueue = dispatch_queue_create("myQueue", NULL);    [captureMetadataOutput setMetadataObjectsDelegate:self queue:dispatchQueue];    [captureMetadataOutput setMetadataObjectTypes:@[AVMetadataObjectTypeUPCECode, AVMetadataObjectTypeCode39Code, AVMetadataObjectTypeCode39Mod43Code,                                                    AVMetadataObjectTypeEAN13Code, AVMetadataObjectTypeEAN8Code, AVMetadataObjectTypeCode93Code, AVMetadataObjectTypeCode128Code,                                                    AVMetadataObjectTypePDF417Code, AVMetadataObjectTypeQRCode, AVMetadataObjectTypeAztecCode]];         //   [self.output setMetadataObjectsDelegate:self queue:dispatch_get_main_queue()]; //   [captureSession addOutput:_output];        self.output.metadataObjectTypes = [self.output availableMetadataObjectTypes];        self.prevLayer = [AVCaptureVideoPreviewLayer layerWithSession:self.session];    self.prevLayer.frame = self.view.bounds;    self.prevLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;    [self.view.layer addSublayer:self.prevLayer];        [self.session startRunning];        [self.view bringSubviewToFront:self.highlightView]; } (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputMetadataObjects:(NSArray *)metadataObjects       fromConnection:(AVCaptureConnection *)connection {    connection.enabled = NO;    CGRect highlightViewRect = CGRectZero;    AVMetadataMachineReadableCodeObject *barCodeObject;    NSString *detectionString = nil;    NSArray *barCodeTypes = @[AVMetadataObjectTypeUPCECode, AVMetadataObjectTypeCode39Code, AVMetadataObjectTypeCode39Mod43Code,                              AVMetadataObjectTypeEAN13Code, AVMetadataObjectTypeEAN8Code, AVMetadataObjectTypeCode93Code, AVMetadataObjectTypeCode128Code,                              AVMetadataObjectTypePDF417Code, AVMetadataObjectTypeQRCode, AVMetadataObjectTypeAztecCode];        for (AVMetadataObject *metadata in metadataObjects)    {        NSLog(@"metadata type %@", [metadata type]);        if ([metadata respondsToSelector:@selector(stringValue)])            NSLog(@"metadata string %@", [(AVMetadataMachineReadableCodeObject *)metadata stringValue]);        for (NSString *type in barCodeTypes)        {            if ([metadata.type isEqualToString:type])            {                barCodeObject = (AVMetadataMachineReadableCodeObject *)[_prevLayer transformedMetadataObjectForMetadataObject:(AVMetadataMachineReadableCodeObject *)metadata];                highlightViewRect = barCodeObject.bounds;                detectionString = [(AVMetadataMachineReadableCodeObject *)metadata stringValue];                break;            }        }                if (detectionString != nil)        {            [self.nativeScannerDelegate didFoundCode:metadata.type result:detectionString];            break;        }    }        [self performSelector:@selector(closeWithoutAnimation) withObject:nil afterDelay:0.1];    self.highlightView.frame = highlightViewRect; }

We found the answer. We re-did all the png files and made sure we had the icon sizes that Apple wanted. Also, all png files needed their alpha channels removed. Jpegs do not have alpha channels but Apple wants png files for the icons, not jpgs.

To add even more confusion https://www.youtube.com/watch?v=gqiYSt4nAFs I am in the same boat. more core vs more memory???
