[swift-users] Coding style for internal/private variables

[Erica Sadun]

From what I've observed, preceding (rather than trailing) single underscores indicate private use. The standard library includes a fair number of "Apple Internal" (I guess now "Swift Team Internal") variables, methods, functions, etc that follow this practice. This practice is, as far as I can tell, uncoupled with access levels. A function named _foo(), while global and public, is still "hands off please".

All in all, other "Hungarian Style" conventions, that is modifying the name to indicate types and uses, are not used in Swift or among most Swift developers.
