Xcode Letter Definitions

What are the letters to the far left of the attached image in Xcode called and where do I find their meanings? I can take a guess what some mean from what we have learned so far but would like to be certain.Screen Shot 2020-09-13 at 5.50.29 AM

Hi @geezer, that’s a great question! I was unable to find a direct source to the Apple documentation but found a link that describes them as “Code Sense”.

A shortened version:

  • C: class
  • S: struct
  • Pr: Protocol
  • Ex: extension (found in the symbol navigator, but not code completion)
  • T: Type (generic type constraint, protocol associated type, etc)

Link to the longer version: objective c - Xcode intellisense meaning of letters in colored boxes like f,T,C,M,P,C,K,# etc - Stack Overflow
