GameKit bug: Default constructor not found for type Apple.Core.Runtime.NSMutableArrayString

When trying to fetch the leaderboards we get this exception. Default constructor not found for type Apple.Core.Runtime.NSMutableArrayString.

Please help

i think this can be fixed by adding perserve markup to your project main link.xml

  <assembly fullname="Apple.Core" ignoreIfMissing="1" preserve="all"/>
