TabbedPage.BarBackgroundColor is not working after installed xamarin.ios-15.0.0.6.pkg

[KennyEng12]

Hi,

I'm using Xamarin Forms v5.0.0.2012, but I got this issue after I upgraded to Xcode 13 and xamarin.ios-15.0.0.6.pkg, so I'm not sure if I'm posted in the right place. Please forgive me and let me know if I'm not.

Steps to Reproduce

1. Install xamarin.ios-15.0.0.6.pkg
2. Run debug

Expected Behavior

Actual Behavior

Environment

Sorry that I couldn't show the details here due to I rolled back Xcode and xamarin-ios package to previous version. The reason of the roll back is because I need to compile the IPA for my work deadline, cannot wait for the fix. But still this need to be fix, else I can never upgrade Xcode and xamarin-ios package.

Example Project (If Possible)

Sorry that I have no example project for this. But you can try to create a blank Xamarin Forms with Xcode 13 and xamarin.ios-15.0.0.6.pkg.

Hope this can help the developers: barTintColor not working in iOS 15, it mentions about:

In iOS 15, UIKit has extended the usage of the scrollEdgeAppearance, which by default produces a transparent background, to all navigation bars. The background is controlled by when your scroll view scrolls content behind the navigation bar. Your screenshots indicate that you are scrolled to the top, and so the navigation bar has selected its scrollEdgeAppearance over the standardAppearance that it would use when scrolled, and on previous versions of iOS.

Thanks,
Kenny.

Hey @KennyEng12, a PR for this is open now (#14649), would you be able to grab the NuGet as described here and let us know if this fixes this issue? That will greatly speed up the review process.

Besides verifying if this particular issue is fixed also be sure to check other scenarios in the same area to make sure that this fix doesn't accidentally has side-effects 🙂

Thanks!
