[regression/8.0.3] Shell.NavBarIsVisible is not working on iOS

[ka4ep]

Description

I have a shell page with defined Shell.NavBarIsVisible="false". When I was using .NET 7.0.101, the bar with the 'hamburger' button is hidden on both Android and iOS.
After upgrading from MAUI 7.0.101 to 8.0.3, the bar is still visible on iOS. It's hidden on Android as expected.

Steps to Reproduce

1. Create a new MAUI app from template and choose framework .NET7 or .NET8.
2. In the AppShell.xaml tag add lines:
   Shell.FlyoutBehavior="Flyout"
   Shell.NavBarIsVisible="False"
3. Compile and run on Android/iOS device or simulator.
4. On iOS .NET 8, the navigation bar is visible, even when stated otherwise.

Hello,
I see that @jsuarezruiz created a pull request that fix the issue.
When this will be release?

I am working on a migration from Xamarin to MAUI and my customer is waiting for this bug fix to release the app on the stores.
Having this ugly navigation bar displayed with no possibility to hide it is a strong impediment.
By the way, I have the bug on both Android and iOS.

Please, send some update that I can communicate to my customer.

Many thanks.

Any update on when this is planned to be fixed?
It's still there on version 8.0.6 and I cannot see a fix for 8.0.7.
It's a blocking point for us!
Any workaround you can suggest?

[KevinJalais]

@johannes-steurer, on my side, the problem has been resolved with version 8.0.7.
If you use a NavigationPage you can set NavigationPage.SetHasNavigationBar(this, false); in your code behind (.xaml.cs file).

I acknowledge that it has not been resolved for Shell component, but as long as I use NavigationPage it's temporary satisfying.

@KevinJalais thanks for the quick feedback. as I use Shell the workaround does not work for me.

Has there been any update on this? I see the PR is still open.
This is a blocker for us as we use Shell navigation and the workaround doesn't work for us.

We have the same issue

[JakodeWet]

Ok, so we found a workaround. You can add the Shell.NavBarIsVisible=False property to your actual page and not the Shell itself. If you have a ContentBasePage, adding it there also works.
Currently we have it on our ContentBasePage and not in the Shell itself and its working.

The suggestion that @JakodeWet made worked for me. It seems like a very fundamental thing that should have been fixed by now

You can write a handler for iOS to solve this problem.
