Adding user inputs from textfield into an array - ios

Question

I am trying to add users names that they have put in a textfield to a basic array. I don’t even know where to start!
The functionality basically is this:
User adds a name in text field
Name is stored in an array so it can be referenced again somewhere else.
As you can tell I’m new to Xcode. I have been taking classes all of which have failed to explain this process. Any help is good Help ! Please :):)
// my view controller so far
class ViewController: UIViewController, UITextFieldDelegate {
#IBOutlet weak var name1: UITextField!
#IBOutlet weak var name2: UITextField!
#IBOutlet weak var name3: UITextField!
var namesArray : [String] = []
override func viewDidLoad() {
super.viewDidLoad()
name1.delegate = self
name2.delegate = self
name3.delegate = self
self.namesArray.append(self.name1.text!)
self.namesArray.append(self.name2.text!)
self.namesArray.append(self.name3.text!)
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()
if textField.returnKeyType == UIReturnKeyType.done {
self.namesArray.append(self.name1.text!)
print(namesArray)
}
return true
}

I am going to assume you have all your logic mashed into one view controller since you are still learning and not worried about larger architecture decisions yet.
At the top of your class, you need an array variable:
// Creates an array and initializes it to be empty.
var userNames: [String] = []
I suspect you also have a button, so that when you press on the button, it grabs the text from the textfield and stores it in the array. You need to set up an IBAction method for that button, and in that method...
// Grab the text, save it in the array, and clear the text.
self.userNames.append(self.myTextField.text)
self.myTextField.text = ""
Later on, you can easily see the list of userNames by accessing self.userNames. e.g.:
let firstUser = self.userNames.first
let lastUser = self.userNames.last
let user47 = self.userNames[46] // assuming you have that many users
