editor.open request doesn't return global declarations or enum cases

[jpsim]

Sending a request to SourceKit for source.request.editor.open with the following key.sourcefile contents:

let global = false

enum MyEnum {
    case First
}

will return the following response:

{
  "key.substructure" : [
    {
      "key.kind" : 4303392864,
      "key.offset" : 20,
      "key.nameoffset" : 25,
      "key.namelength" : 6,
      "key.bodyoffset" : 33,
      "key.bodylength" : 16,
      "key.length" : 30,
      "key.substructure" : [

      ],
      "key.name" : "MyEnum"
    }
  ],
  "key.offset" : 0,
  "key.diagnostic_stage" : 4303392912,
  "key.length" : 51
}

Missing are the substructures for the global (source.lang.swift.decl.var.global) and enum element (source.lang.swift.decl.enumelement).

This makes it difficult to determine the structure of this file and sourcekitten does something pretty hacky to work around this issue.

This is a bug in SourceKit on Apple's side, unfortunately. See rdar://18845613.

We could add a workaround to sourcekitten by making cursorinfo requests for offsets at case * when an source.lang.swift.decl.enum is detected. Only searching for case * inside the enum body based on its bodyoffset and bodylength.

This is resolved as of Xcode 7 Beta 3 and ship with jazzy along with Swift 2.0 support.

Does it return them as functions now?

No, see https://github.com/jpsim/SourceKitten/commit/fe140070b06340b02d3f677e0e5a98a3144ecbe2
