Customize the cells in a UITableView

cellForRowAt.swift

//  Use tableView(_:cellForRowAt:) to customize the cells in a table view.
//  This example demonstrates an instance of how one of this app's table views uses this method.


//  Create some sort of data source. This is often an array or, in this case, a dictionary.
var dataSource: [String: String] {
    return ["cellForRowAt: indexPath": "Update cell information based on the data source\nReturns a UITableViewCell.",
            "numberOfRowsInSection: Int": "Determine the number of rows needed for each section of the tableView\nReturns an Int",
            "titleForHeaderInSection: Int": "Set the title for a particular section of your tableView\nReturns a String"]
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
//  This table view uses a custom cell, DataSourceTableViewCell, that was created in a separate file. This cell has two
//  UILabels, a title label and a detail label.
    let cell = tableView.dequeueReusableCell(withIdentifier: "DataSourceTableViewCell") as! DataSourceTableViewCell

//  Get the titles and details for their respective labels in an array.
    var titles = Array(dataSource.keys)
    var details = Array(dataSource.values)

//  Access the title based on the indexPath's row property and set it to the title label's text property.
//  Set the color of the label to green.
    cell.title.text = titles[indexPath.row]
