Hi!
I'm trying to build my Xamarin iOS app on Mac and failing on an error related to a deprecated command line parameter.
I tried targeting iphone 10, 11 and above but still failing on same error.
I Updated NuGets to latest versions, also tried creating an empty ResourceRules.plist file.

Xcode 12.1 (17222)
Build 12A7403
=== Xamarin.Mac ===
Version: 6.22.1.26 (Visual Studio Community)
=== Xamarin.iOS ===
Version: 14.4.1.3 (Visual Studio Community)
=== Operating System ===
Mac OS X 10.15.7

I saw some references to this error mainly in old posts but couldn't find a recent solution.
Any help would be appreciated.
Cheers,
