Updating tableview binded to array error - swift

Question

I am extremely new to Swift so I am guessing this is a rookie mistake but here's my situation:
I am trying to create an application that allows you to add things to a list. I have a NSTextField where users input there data and a NSButton to add that data to the myTeam array. The tableView is binded (I think that's what you call it) to the myTeam array.
When I run the application a table containing the preset values of myTeam populate the table view correctly, but when I add to this array nothing happens. After research, I found this question.
Unfortunately, like most swift tutorials and Q&A, it was for iOS. But I thought I would give it a try. I added
self.tableView.reloadData()
self.refresher.endRefreshing()
to my code, and received two errors: Value of type '(NSTableView, NSTableColumn?, Int) -> Any?' has no member 'reloadData' and Value of type 'ViewController' has no member 'refresher', respectively.
Heres my code below:
import Cocoa
import Darwin
class ViewController: NSViewController, NSTableViewDataSource {
var myTeam = ["Test", "Test2"]
#IBOutlet weak var myText: NSTextField!
#IBOutlet weak var AddMember: NSButton!
#IBAction func addmem(_ sender: Any) {
myTeam.append(myText.stringValue);
self.tableView.reloadData()
self.refresher.endRefreshing()
}
override func viewDidLoad() {
super.viewDidLoad()
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
// MARK: DataSource
func numberOfRows(in tableView: NSTableView) -> Int {
return myTeam.count
}
func tableView(_ tableView: NSTableView, objectValueFor tableColumn: NSTableColumn?, row: Int) -> Any? {
return myTeam[row]
}
}
P.S. I used this tutorial to get as far as I did.

Simplest solution, we are going to use (full) Cocoa Bindings:
Replace the entire code with
import Cocoa
class ViewController: NSViewController {
#IBOutlet weak var myText: NSTextField!
#objc dynamic var myTeam = ["Test", "Test2"]
#IBAction func addmem(_ sender: NSButton) {
myTeam.append(myText.stringValue)
}
}
In Interface Builder select the table view (not the enclosing scroll view) and press ⌥⌘6 (Connections Inspector)
Disconnect dataSource
Press ⌥⌘7 (Bindings Inspector)
Bind Content to ViewController > Model Key Path myTeam
Since you are still using objectValueFor I assume that the value of the table cell view is already bound to objectValue.
macOS doesn't know a refresher.
