Unable to hide the navigationBar when embedding SwiftUI in UIKit

by

UIHostingViewController respects the navigationBarHidden value of your SwiftUI view. You can either call .navigationBarHidden(true) at the end of your SwiftUI view, or you can use the custom UIHostingController subclass shown in the example below.

Solution:

import SwiftUI
import UIKit

class YourHostingController <Content>: UIHostingController<AnyView> where Content : View {

  public init(shouldShowNavigationBar: Bool, rootView: Content) {
      super.init(rootView: AnyView(rootView.navigationBarHidden(!shouldShowNavigationBar)))
  }

  @objc required dynamic init?(coder aDecoder: NSCoder) {
      fatalError("init(coder:) has not been implemented")
  }
}

Example of usage:

let hostVc = YourHostingController(shouldShowNavigationBar: false, rootView: YourSwiftUIView())
