How to: Change UIModalPresentationStyle from .automatic to .fullscreen for a UIViewController

Question

I attempted to set modalPresentationStyle to .fullscreen following the Apple Documentation.

After setting the modalPresentationStyle to .fullscreen shown in the code below, the system still presents the viewControllers in UIModalPresentationStyle.automatic "the system default"

//Presentation Style
let homeVC = HomeController(viewModel: viewModel)
homeVC.modalPresentationStyle = UIModalPresentationStyle.fullScreen

A framework called XCoordinator controls navigation within this application, here is an example on how it is done.

switch route { 
case .home: 

let viewModel = HomeViewModelImpl(router: anyRouter) 
let viewController = HomeController(viewModel: viewModel) 

return .push(viewController)

}

Define "not working". [Edit] your question with more specific details. — rmaddy, Oct 08 '19 at 19:12
@NitinAlabur Yep! The project uses view controllers created programmatically , the storyboard is not in play here — Joshua, Oct 08 '19 at 19:19
Are you presenting `homeVC` itself or a view controller that contains `homeVC` (like a navigation controller, for example)? What does your code look like where you do the actual presentation? — TylerP, Oct 08 '19 at 19:31
@TylerTheCompiler views are pushed on the stack using a framework called XCoordinator like so `switch route { case .home: let viewModel = HomeViewModelImpl(router: anyRouter) let viewController = HomeController(viewModel: viewModel) return .push(viewController)` — Joshua, Oct 08 '19 at 19:40
I've never used XCoordinator but taking a quick look at the documentation and I see `.push` will just push it onto the navigation stack so I doubt that will ever be modal. I suggest maybe looking into `.present` instead. As I said I haven't used it but that would be my guess. Whichever way you look at it though you have given control of presentation over to XCoordinator so the issue lies there. — Upholder Of Truth, Oct 08 '19 at 19:49
@Joshua Do not put details in comments. Please [edit] your question with all relevant details. — rmaddy, Oct 08 '19 at 20:28
@rmaddy Updated the question with the details, sorry about that . — Joshua, Oct 08 '19 at 21:53

The TabBarCoordinator has a rootViewController when XCoordinator is setup.

The solution here was to set the .modalPresentationStyle to .fullscreen off of the rootViewController .

rootViewController.modalPresentationStyle = .fullscreen

Please note this has to be called after any super method in your class file
