Receive user defaults which we stored when user logged in (swift3...)

1) After logging I retrieve values from a database( OK )

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.

        // Receive user defaults which we stored when user logged in

    let defaults = UserDefaults.standard
    let firstname = defaults.string(forKey: "usernameValue")
    let lastname = defaults.string(forKey: "nameValue")
    let connect_email = defaults.string(forKey: "emailValue")
    let event_mois = defaults.array(forKey: "event_mois")
    }

2) After viewDidLoad() I make an array to feed a display (OK)

var sections = [
    Section(genre: "🦁 Event du mois",
            movies: ["The Incredibles", "The Incredibles"],
            expanded: false),
    Section(genre: "💥 Top Event",
            movies: ["Guardians of the Galaxy", "The Flash", "The Avengers", "The Dark Knight"],
            expanded: false),
    Section(genre: "👻 Event Fribourg",
            movies: ["The Walking Dead", "Insidious", "Conjuring"],
            expanded: false)
]

3)I would now like to take event_mois table which I retrieved from my database to put it in var sections. But I can not use this array outside of viewDidLoad and I can not also put var sections in viewDidload.

Can someone help me? Thank you

You just need to define sections to be an instance property of your class, then you can access it anywhere from your class.

class MyViewController: UIViewController {
    var sections: [Section]?

    override func viewDidLoad() {
        super.viewDidLoad()
        // Receive user defaults which we stored when user logged in

        let defaults = UserDefaults.standard
        let firstname = defaults.string(forKey: "usernameValue")
        let lastname = defaults.string(forKey: "nameValue")
        let connectEmail = defaults.string(forKey: "emailValue")
        guard let eventMois = defaults.array(forKey: "event_mois") as? [Section] else {return}

        if let sections = sections {
            sections.append(eventMois)
        } else {
            sections = eventMois
        }
    }

}

And use the Swift naming convention, which is lower-camelcase for variable names.

You can not use that array in other methods since it will be out of scope. Solution : define the array as a property, in this way you can use it anywhere in the class, the property goes in the class outside all methods.

class YourClass {

    var sections : [Section] = []

    override func viewDidLoad() {
        super.viewDidLoad()
       // your code
    }
}
