Adds image from library to a parent view and animates it by growing from the center with a springy bounce

Add image asset with bounce-in animation

- (void)addCompletionCheck {
    // image asset. Change to whatever your's is named
    UIImage *check = [UIImage imageNamed:@"uploadCompleteCheck"];

    UIView *checkView = [UIView new];
    
    // Calculate position based on parent and initial size of asset
    // Math is such that it puts the image in the center of parent
    // self.progressView is the parent view in this case. Change to your superview
    int x = self.progressView.frame.size.width/2 - checkImageView.frame.size.width/2;
    int y = self.progressView.frame.size.height/2 - checkImageView.frame.size.height/2;
    int defaultWidth = checkImageView.frame.size.width;
    int defaultHeight = checkImageView.frame.size.height;
    
    // add the imageview to the superview
    [checkView addSubview:checkImageView];
    [self.progressView addSubview:checkView];
    
    // position subview and its subview

    CGAffineTransform currentTransform = checkView.transform;
    CGAffineTransform newTransform = CGAffineTransformScale(currentTransform, 0, 0);
