Swift: save text field in an array

How to save the text of 2 textfields in an array?

This is what I tried. I use println to check if the values are in the array. But it seems it doesn't work.

Can anyone explain it and please, explain each step. Thank you

1- I create a swift file: novaClass.swift. I create an struct inside

struct novaClass {
    var img : String
    var text : String
}

2- ViewController.swift Declare an array

    var nouArray = [novaClass]()

3- save the text field in the array

@IBAction func save(sender: AnyObject) {

    //I put the text of 2 text fields in the array
    var nouText = novaClass(img: textField1.text, text: textField2.text) 
    nouArray.append(nouText)

    //I check the array
    println(nouArray) // this gives "[_.novaClass]" I do not understand

}

That's the expected behaviour in Swift. Swift objects don't have a description property by default, so println defaults to printing the class name.

Your class can adopt the Printable protocol (which have been renamed to CustomStringConvertible in Swift 2) to provide more detailed printouts:

struct novaClass: Printable {

    var img : String
    var text : String

    var description: String {
        get {
            return "{img: \(img), text: \(text)}"
        }
    }
}

Now try it:

var array = [novaClass]()
let x = novaClass(img: "foo", text: "bar")
let y = novaClass(img: "foo2", text: "bar2")
array.append(x)
array.append(y)
println(array) // will print: "[{img: foo, text: bar},{img: foo2, text: bar2}]"

You should check it by

println(nouArray[0].text)
println(nouArray[0].img)

Printing array as object will print its title only
