deep copy for array of objects in swift

Question

I have this class named Meal

class Meal {
    var name : String = \"\"
    var cnt : Int = 0
    var price : String = \"\"
    var img : String = \"\"
    va         


        

Answer 1

A simple and quick way is to map the original array into the new copy:

let copyOfPersons: [Person] = allPersons.map({(originalPerson) -> Person in
        let newPerson = Person(name: originalPerson.name, age: originalPerson.age)
        return newPerson
    })

The new Persons will have different pointers but same values.
