[swift-evolution] [Review] SE-0023 API Design Guidelines

[Marc Knaup]

What is the rationale behind naming enumeration cases in upper camel case?

*Follow case conventions:* names of types, protocols and enum cases are
> UpperCamelCase. Everything else is lowerCamelCase.


let a = NSComparisonResult.OrderedSame  // refers to a value, but is
upper-case
let b = NSDate.distantFuture            // refers to a property/value, but
is lower-case

   - everything related to types (type names, protocol names, generic type
   parameter names) should be upper camel case
   - everything else (function names, property names, variable names, etc.)
   should be lower camel case

This is already the current and the proposed recommendation with
enumeration cases being the only exception.
Enumeration cases are not types.
