GetPlatform node returns "IOS" on tvOS

Development Platform & Builds Mobile

Steps to Duplicate:

  1. Create First Person Blueprint project, “Desktop/Console”, " Quality", “No Starter Content”
  2. Open the default level blueprint
  3. Add a “Get Platform Name”, hook it to “Print”, and hook execution up to BeginPlay.
  4. Import a development certificate and provision.
  5. Launch on AppleTV†

Observe the debug print report “IOS” Instead of “tvOS”.

A quick skim would make it seem that something like the patch below would work, but I would guess that there’s some deeper complications.
