Preview Assistant - Language Selection not showing up


In xCode 8.3.3, there doesn’t appear to be a language selector in the Assistant Editor, as shown on page 127 (6 ed).

A screen shot from my Preview Assistant:

Does anyone know where this function has been moved to for newer versions of xCode?


UPDATE: SOLVED: This may be due to an xCode bug with something to do with the bundle. I fixed this problem by:

  1. Deleting the app from the simulator
  2. Restarting xCode
  3. Product -> Clean from the top menu
  4. Product -> Clean Build Folder from the top menu
