/**
 
 This is code that I reversed from sharingd LaunchDaemon, the reason i included this code is
 becausae this process is one that we are intervening on to prevent the exception through at the
 if (!handler) { check
 }
 
 there is PROBABLY a more proper way to fix this, but I'm honestly not certain apple had any intention
 on making AirDrop ever work bidirectionally on tvOS.
 
 I realize some of the code isn't PERFECT replica, but its close enough to follow the flow.
