[Bug] iOS Build error after updating the MSAL version

[jbe2277]

Library version used

4.74.1

.NET version

After updating MSAL from 4.68.0 to 4.74.1 I get a build error for iOS.

<PackageVersion Include="Microsoft.Identity.Client.Broker" Version="4.74.1" />
<PackageVersion Include="Microsoft.Identity.Client.Extensions.Msal" Version="4.74.1" />

Scenario

PublicClient - mobile app

Is this a new or an existing app?

The app is in production, and I have upgraded to a new version of MSAL

Issue description and reproduction steps

I have updated MSAL with this commit:

• https://github.com/jbe2277/waf/commit/3bb8eef33f139e551963327c032ce145be39a7b2

The GitHub action to build the iOS version failed:

• https://github.com/jbe2277/waf/actions/runs/16915677863/job/47934812330

with the error message:

We encountered a similar issue when building the iOS release version, with the following error message:

/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk.net9.0_18.4/18.4.9289/targets/Xamarin.Shared.Sdk.targets(1652,3): error : ld: building for 'iOS', but linking in dylib (/Users/mobileframework/Documents/Build/Source/MAUI/Ifs.Maui/obj/Release/net9.0-ios/ios-arm64/nativelibraries/Contents/MonoBundle/msalruntime_arm64.dylib) built for 'macOS'

This error occurs when using Microsoft.Identity.Client v4.76.0, but does not occur with older versions such as v4.72.1.

I believe this is a similar case to #5407 The same cleanup approach should work here as well.
