How to use an enum and switch() with UITableViewController in Swift

Question

My UITableView has two sections, so I created an enum for them:

private enum TableSections {
    HorizontalSection,
    VerticalSection
}

Answer 1

In order to do this, you need to give your enum a type (Int in this case):

private enum TableSection: Int {
    horizontalSection,
    verticalSection
}

This makes it so that 'horizontalSection' will be assigned the value 0 and 'verticalSection' will be assigned the value 1.

Now in your numberOfRowsInSection method you need to use .rawValue on the enum properties in order to access their integer values:

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    switch section {

    case TableSection.horizontalSection.rawValue:
        return firstArray.count

    case TableSection.verticalSection.rawValue:
        return secondArray.count

    default:
        return 0
    }
}
