iOS: How to add app specific settings to iOS's Settings app?

[baskren]

TL;DR: I've answered my own question here and have submitted it here for when I go looking again to the answer to this question.

In Xcode, I can create a new app, add a iOS Settings.bundle resource, build the app, and see (in the iOS Settings app) the settings in the newly added Settings.bundle/Root.plist file.

So I'd like to do the same thing with an Uno.Platform app. Here's what I've tried:

• Create a new blank .net9.0 Uno.Platform app, MyApp.
• copy Settings.bundle from the above Xcode created iOS app to MyApp/MyApp/Platforms/iOS/Settings.bundle.
• add the following to MyApp.csproj:

  <ItemGroup>
    <BundleResource Condition=" $(TargetFramework.Contains('-ios'))  " Include="Platforms\iOS\Settings.bundle\Root.plist" />
  </ItemGroup>

When I go build, I see the following in the build logs:

Settings.bundle/Root.plist) => Platforms/iOS/Settings.bundle/Root.plist
			projectAbsoluteDir=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage
			IsRemoteBuild=False
			isDefaultItem=False
			LocalMSBuildProjectFullPath=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage/UnoIntersessionStorage.csproj
			LocalDefiningProjectFullPath=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage/UnoIntersessionStorage.csproj
			originalItemAbsolutePath=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage/Platforms/iOS/Settings.bundle/Root.plist
			itemAbsolutePath=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage/Platforms/iOS/Settings.bundle/Root.plist
			originalRelativeToDirectory=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage
			relativeToDirectory=/Users/ben/Development/Uno/UnoIntersessionStorage/UnoIntersessionStorage

BundleResource.GetLogicalName (Platforms/iOS/Settings.bundle/Root.plist) => LogicalName=Platforms/iOS/Settings.bundle/Root.plist (prefixes=Platforms/iOS/Resources/)

... so I it appears that the bundle it being packaged during the build. In Finder, right clicking on MyApp/bin/Debug/net9.0-ios/iosssimulator-arm64/MyApp.app and selecting Show Package Contents, reveals that the Settings.bundle is located in Platforms/iOS of the bundle. Settings.bundle is not in the package's root, where it should be.

So, how to move it to the root of the app's package? Use the <Link> tag in the <BundleResource> to indicate to the build process to where place Settings.bundle/Root.plist:

  <ItemGroup>
    <BundleResource Condition=" $(TargetFramework.Contains('-ios'))  " Include="Platforms\iOS\Settings.bundle\Root.plist" >
        <Link>Settings.bundle/Root.plist</Link>
    </BundleResource>
  </ItemGroup>
