Opening URLs

The data for each course contains the URL of a web page that has a description of that class. The last functionality for this app is to open that web page in the user’s browser if the user double-clicks on the course.

To get the table view to respond to a double-click you must set the doubleAction and target of the table view. Unlike most target/action pairs, doubleAction must be set programmatically. Open MainWindowController.swift and add an outlet to the table view and the array controller:

class MainWindowController: NSWindowController {

    @IBOutlet var tableView: NSTableView!
    @IBOutlet var arrayController: NSArrayController!

    let fetcher = ScheduleFetcher()
    dynamic var courses: [Course] = []

Connect the outlets ...
