My content view (custom tab bar) gone first time load after view side menu it appear

[hafiz013]

how bugs reproduce

1. load content view (custom tab bar) with menu but the content menu (tab bar) gone.
2. I click button to open menu
3. Then suddenly, custom tab bar appear.

Expected:

1. first time load content view(custom tab bar) should appear without need to click floating button.

Sample configuration in side class AppDelegate:
SideMenuController.preferences.basic.hideMenuWhenEnteringBackground = false SideMenuController.preferences.basic.direction = .right SideMenuController.preferences.basic.position = .sideBySide

Content View Controller add view programmatically under class CustomTabBarViewController extend UITabBarController :
`private var _customTabBar:CustomTabBar!
_customTabBar = UINib.init(nibName: "CustomTabBar", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! CustomTabBar
self.view.addSubview(_customTabBar)

    _customTabBar.translatesAutoresizingMaskIntoConstraints = false
    
    _customTabBar.heightAnchor.constraint(equalToConstant: 52).isActive = true
    _customTabBar.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
    _customTabBar.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
    _customTabBar.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
    
    _customTabBar.layer.borderWidth = 1.0
    _customTabBar.layer.borderColor = UIColor(hex: "#989898")?.cgColor
    _customTabBar.clipsToBounds = true`

Please help, it is need to cache or manually add content view controller for first time load?
