    It’s value of enum.

    enum CompassPoint {
    case north
    case south
    case east
    case west
}

    When you have that enum like in example above then you can use that:

    let compassPoint = CompassPoint.west
let compassPoint: CompassPoint = .west

    When the type is known then you can use the syntax with ..

    It could be any type with a member called bottom. It has been omitted because the compiler can parse "implicit member expressions". It means that whenever the compiler can infer the type from the context, you do not need to write it. Back to your problem: you could do a "Command"-Click on the expression and let XCode tell you more about the context.
