Using XCode 12 Beta and iOS 14, I'm unable to hide the status bar when a NavigationView is nested inside a TabView. Consider:

Code Block      TabView(selection: $selection) {
       NavigationView {
        ViewOne()
        .navigationBarTitle("View One")
      }
      .tabItem {
        Label("View One", systemImage: "doc.plaintext")
      }
      .tag(TabItem.viewOne)
      .statusBar(hidden: true)
    }

The above code only hides the status bar if you remove the parent TabView. I also tried to hide the status bar onAppear:

Code Block      TabView(selection: $selection) {
       NavigationView {
        ViewOne()
        .navigationBarTitle("View One")
        .onAppear {
          isStatusBarHidden = true
        }
        .onDisappear {
          isStatusBarHidden = false
        }
      }
      .tabItem {
        Label("View One", systemImage: "doc.plaintext")
      }
      .tag(TabItem.viewOne)
      .statusBar(hidden: isStatusBarHidden)
    }

This also doesn't work. I've also tried hiding the status bar directly on the TabView. Any suggestions?

Have the "same" issue:

Code Block swiftimport SwiftUI
struct PXStartupView: View {
    @State var ready = false
    var body: some View {
        NavigationView{
            ZStack{
                Color.white
                Image("Icon-Startup")
                NavigationLink(destination: PXMainView(), isActive: self.$ready){
                    EmptyView()
                }
            }
            .navigationBarHidden(true)
            .navigationBarBackButtonHidden(true)
            .navigationBarTitle("", displayMode: .inline)
            .edgesIgnoringSafeArea(.all)
        }
        .navigationBarHidden(true)
        .navigationBarBackButtonHidden(true)
        .navigationBarTitle("", displayMode: .inline)
        .navigationViewStyle(StackNavigationViewStyle())
        .statusBar(hidden: true)
    }
}

Works fine on iOS 13 (not status bar), but show status bar on iPad iOS 14

Hopefully this helps someone diagnose - tested via Xcode 12.0 beta 2 and iOS 14.0 public beta:

SwiftUI views NOT wrapped in NavigationView hide the status bar correctly via ".statusBar(hidden: true)" modifier.
SwiftUI views wrapped in NavigationView do not process the status bar correctly via ".statusBar(hidden: true)" modifier.
Not seeing much of a difference yet regarding portrait vs landscape.

Worked correctly at least through 13.5 but current 13.x.

Cheers.

Same here — .statusBar(hidden: true) doesn't work if view is wrapped in NavigationView on iOS 14.

I'm having the same issue...statusBar cannot be hidden on any level if the view has a NavigationView...

Has anyone come up with a solution?

XCode 12, iOS 14

Man, I just wish Apple would spend some time cleaning up those SwiftUI bugs. It's crazy how many bugs apple just leaves there!

I faced the same issue, but was able to solve it by adding more keys to the info.plist file (Xcode 12 and iOS14).

As stated in this thread (https://stackoverflow.com/questions/56896719/how-to-hide-the-status-bar-in-swiftui) you just have to paste

<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

in your info.plist file.

Afterwards


.edgesIgnoringSafeArea(.all)
.statusBar(hidden: true)

worked just fine for me.

The issue is finally solved with Xcode 13.0 beta 3 - you can attach the statusBarHidden modifier to both a TabView and a NavigationView and the status bar hides as expected.

I found the only way to get this to work per view is to wrap your rootView in a HostingController like:

class HostingController<ContentView>: UIHostingController<ContentView> where ContentView : View {

    

    init(view: ContentView) {

        super.init(rootView: view)



        NotificationCenter.default.addObserver(forName: .onDarkStatusBar, object: nil, queue: .main) { _ in

            self.statusBarEnterDarkBackground()

        }

        

        NotificationCenter.default.addObserver(forName: .onLightStatusBar, object: nil, queue: .main) { _ in

            self.statusBarEnterLightBackground()

        }

        

        NotificationCenter.default.addObserver(forName: .onShowStatusBar, object: nil, queue: .main) { _ in

            self.statusBarShow()

        }

        

        NotificationCenter.default.addObserver(forName: .onHideStatusBar, object: nil, queue: .main) { _ in

            self.statusBarHide()

        }

    }

    

    @objc required dynamic init?(coder aDecoder: NSCoder) {

        fatalError("init(coder:) has not been implemented")

    }

    

    private var isDarkContentBackground = false

    private var isStatusBarHiden = false



    func statusBarEnterDarkBackground() {

        isDarkContentBackground = false

        setNeedsStatusBarAppearanceUpdate()

    }



    func statusBarEnterLightBackground() {

        isDarkContentBackground = true

        setNeedsStatusBarAppearanceUpdate()

    }

    

    func statusBarHide() {

        isStatusBarHiden = true

        setNeedsStatusBarAppearanceUpdate()

    }



    func statusBarShow() {

        isStatusBarHiden = false

        setNeedsStatusBarAppearanceUpdate()

    }



    override var preferredStatusBarStyle: UIStatusBarStyle {

        if isDarkContentBackground {

            return .lightContent

        }

        else

        {

            return .darkContent

        }

    }

    

    override var prefersStatusBarHidden: Bool {

      return isStatusBarHiden

    }



}

Use as

let window = UIWindow(windowScene: windowScene)

            window.rootViewController = HostingController(view: contentView)

Then send out a notification from onDissapear and onAppear.

extension Notification.Name {

   static let onDarkStatusBar = Notification.Name("onDarkStatusBar")

    static let onLightStatusBar = Notification.Name("onLightStatusBar")

    static let onHideStatusBar = Notification.Name("onHideStatusBar")

    static let onShowStatusBar = Notification.Name("onShowStatusBar")

}

Using

                            .onAppear {

                                NotificationCenter.default.post(name: Notification.Name.onHideStatusBar, object: nil)

                            }

                            .onDisappear {

                                NotificationCenter.default.post(name: Notification.Name.onShowStatusBar, object: nil)

                            }
