openMainMenu works properly and animates the view in, closeMainMenu does not animate..

ContainerViewController.mm

- (void)openMainMenu {
    _menu_opened = YES;
    _darknessOverlay.hidden = NO;
    
    CGRect oldFrame = _menuView.frame;
    
    CGRect f = _menuView.frame;
    f.origin.x = _menuView.frame.size.width * -1;
    _menuView.frame = f;
    
    _menuView.hidden = NO;
    
    [UIView animateWithDuration:0.3
      animations:^{
       _menuView.frame = oldFrame;
    }];
    
    [self.leftMenuButton setImage:[UIImage imageNamed:@"home-back"] forState:UIControlStateNormal];
}

- (void)closeMainMenu {
    _menu_opened = NO;
    _darknessOverlay.hidden = YES;
    
    [UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionBeginFromCurrentState
      animations:^{
       CGRect f = _menuView.frame;
       f.origin.x = _menuView.frame.size.width * -1;
       _menuView.frame = f;
      } completion:nil];
     
    [self.leftMenuButton setImage:[UIImage imageNamed:@"home"] forState:UIControlStateNormal];
}

- (IBAction)leftMenuButtonTouched:(id)sender {
  if (_menu_opened == NO) {
    [self openMainMenu];
  } else {
    [self closeMainMenu];
  }
}
