Xam.Shell.Badge iOS 15 Rendering Bug

Hi,

There seems to be a breaking change with iOS 15. If you run the sample project, you'll get this:

It's not honoring the text color or the background color.

Could you please look into it? @galadril @SnowPowerCore @LukeWinthorpe

XF version: 5.0.0.2196

Thanks,

iOS 15 is a pain for a lot of nugets

@darrabam, @jm-parent, can you confirm this isn't fixed by the 1.0.13 nuget package version?

Hello, @darrabam, @jm-parent, i will close this issue, if the problem is still there for you, feel free to open a new issue, but i have already tested the latest 1.0.13 nuget package on iOS - it should be respecting the background and text colors.

@SnowPowerCore Many thanks! I've tested 1.0.17 on my project, but unfortunately doesn't fix this issue. I'll open a new ticket with details as advised.

@darrabam, thank you for replying, let's continue within this issue. I've updated the recent PR #31 with one change on how iOS handles the color to match the Android's behavior, so it may help you.

@SnowPowerCore Unfortunately, still not fixed. I've tried Xam.Shell.Badge 1.0.18 with the latest Xamarin (5.0.0.2337) and Xcode 13.2.1, iOS SDK 15.2:

We ran into this issue as well. iOS 15 has added a ScrollEdgeAppearance property to the UITabBar that causes this behavior. To get this to work, the UIColor needs to be applied to the UITabBar Standard Appearance - StackedLayoutAppearance, InlineLayoutAppearance, CompactInlineLayoutAppearance, StandardAppearance, AND (in iOS 15) the ScrollEdgeAppearance. If given the opportunity, I'll try to throw up a PR.

@AaronBastian, you're free to create PR if you wish to help.

Hello guys, @AaronBastian do you have any example for where to set the ScrollEdgeAppearance property? I've created a custom renderer and set that property there, but when running the app the badge isn't shown at all(

@AaronBastian, i will not be able to test this in the close future as i'm stuck on macOS 10.14, which doesn't support XCode 13, which is required for iOS 15.

@AaronBastian, recently i've acquired ability to test stuff on the latest iOS, so i may return into this issue.
