Example 1: JSONDecoder

struct GroceryProduct: Codable {
    var name: String
    var points: Int
    var description: String?
}

let json = """
{
    "name": "Durian",
    "points": 600,
    "description": "A fruit with a distinctive scent."
}
""".data(using: .utf8)!

let decoder = JSONDecoder()
let product = try decoder.decode(GroceryProduct.self, from: json)

print(product.name) // Prints "Durian"

Example 2: .unshift

let monTableau = ['un', 'deux','trois', 'quatre'] ;
monTableau.unshift('zero') ; 
//console.log(monTableau) ;
 
 

 let monTableau2D = [
     ['Mark' , 'jeff' , 'Bill'] , 
     ['Zuckerberg' , 'Bezos' , 'Gates']
 ] ;
 monTableau2D[1].unshift('test') ; 
 //console.log(monTableau2D) ;
