Application crashes after updating to Xcode Version 9.2 (9C40b)

I have recently updated my Xcode, after updating the Xcode I am facing a crash. Here the crash happening

    UIBlurEffect *blur = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];
    UIVisualEffectView *vsview = [[UIVisualEffectView alloc]initWithEffect:blur];


    _bgView = [[UIView alloc]initWithFrame:[UIScreen mainScreen].bounds];
    _bgView.backgroundColor = [UIColor colorWithWhite:0 alpha:0.8];
    _bgView.alpha = 0;
    _bgView.userInteractionEnabled = YES;
    UITapGestureRecognizer *buttonTap2 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleTap:)];

    buttonTap2.cancelsTouchesInView = NO;
    vsview.frame = _bgView.bounds;
    _bgView = vsview;
    [_bgView addGestureRecognizer:buttonTap2];


    _normalImageView = [[UIImageView alloc]initWithFrame:self.bounds];
    _normalImageView.userInteractionEnabled = YES;
    _normalImageView.contentMode = UIViewContentModeScaleAspectFit;
    _normalImageView.layer.shadowColor = [UIColor blackColor].CGColor;
    _normalImageView.layer.shadowRadius = 5.f;
    _normalImageView.layer.shadowOffset = CGSizeMake(-10, -10);



    _pressedImageView  = [[UIImageView alloc]initWithFrame:self.bounds];
    _pressedImageView.contentMode = UIViewContentModeScaleAspectFit;
    _pressedImageView.userInteractionEnabled = YES;


    _normalImageView.image = _normalImage;
    _pressedImageView.image = _pressedImage;


    [_bgView addSubview:_menuTable];

Where _bgView is UIView and _menuTable is UITableView;

the logs stating the following error message.

Assertion failure in -[UIVisualEffectView _addSubview:positioned:relativeTo:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit/UIKit-3698.34.4/UIVisualEffectView.m:1558

Terminating app due to uncaught exception NSInternalInconsistencyException', reason: '; layer = ; contentOffset: {0, 0}; contentSize: {281.25, 72}; adjustedContentInset: {0, 0, 0, 0}> has been added as a subview to ; layer = >. Do not add subviews directly to the visual effect view itself, instead add them to the -contentView.

Before updating he Xcode it is working fine.

This error message is caused by trying to add a subview to the UIVisualEffectView.

Change 

UIVisualEffectView *vsview = [[UIVisualEffectView alloc]initWithEffect:blur];
[vsview addSubview:newView];

to 

UIVisualEffectView *vsview = [[UIVisualEffectView alloc]initWithEffect:blur];
[vsview.contentView addSubview:newView];

Make sure that you are not adding anything as child to the visual effect view
