Question

I wanted to create a custom TabBar using UITabBarController I have set my tabBar Color to the color that i want

 self.tabBar.backgroundColor = .basePurpleLight

in viewDidLoad

turns out, everytime i fetch a data, it turns back to light white. and the cause of the problem is the TabBar Visual effect
