Here is a basic class documentation example:
/// Class description
class Student {
// Member description
var name: String
/// Method description
///
/// - parameter content: parameter description
///
/// - returns: return value description
func say(content: String) -> Bool {
print("\(self.name) say \(content)")
return true
}
}
Note that with Xcode 8, you can generate the documentation snippet with command+option+/.
