2. Quick Tutorial

First of all, consider the Example project in this repository a best practice.

1. Conform your table view controller to TableEnumerated:

extension ViewController: TableEnumerated {
    // ...
}

2. Enumerate your sections:

extension ViewController: TableEnumerated {
    enum Section: Int, SectionEnumeration {
        case user
        case setting
    }
}

3. Enumerate rows for each section:

extension ViewController: TableEnumerated {
    enum UserRow: Int, RowEnumeration {
        case avatar
        case biography
        
        var text: String? {
            switch self {
            case .avatar:
                return "iMoe"
            case .biography:
                return "A developer."
            }
        }
        
        var reuseIdentifier: String? {
            switch self {
            case .avatar:
                return "Avatar Cell"
            case .biography:
                return "Cell"
            }
        }
    }

    enum RichTextRow: Int, RowEnumeration {
        case row1
        case row2
        
        var text: String? {
            switch self {
            case .row1:
                return "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
            case .row2:
                return "Ut enim ad minim veniam."
            }
        }
        
        var reuseIdentifier: String? {
            return "Rich Cell"
        }
    }
    
    enum Section: Int, SectionEnumeration {
        case user
        case setting
        
        var RowsInSection: RowEnumerated.Type {
            switch self {
            case .user:
                return ViewController.UserRow.self
            case .setting:
                return ViewController.RichTextRow.self
        }
    }
}

4. Use shortcut methods to layout your table view:

extension ViewController: UITableViewDataSource {
    func numberOfSections(in tableView: UITableView) -> Int {
        return numberOfEnumeratedSections
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return numberOfEnumeratedRows(in: section)
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        return enumeratedCell(at: indexPath, inside: tableView)
    }
}
