Question

What do the "S", "T" and "Pr" icons that appear in the "auto completion box" in Swift playground mean? Are there other kinds?

Thanks!

Answer (for search engine indexing)

C  : Classes
Pr : Protocols
f  : Functions
S  : Structs
U  : Unions
E  : Enums
T  : Types
V  : Globals

Answer 1

These are the same abbreviations that appear in the Symbol navigator, where they are defined for you (as the attached screen shot shows):

Thus, as the table tells you, C means class, Pr means protocol, and so on.
