Xcode Swift check if array contains object

Question

I have this array :

  var preferiti : [ModalHomeLine!] = []

I want to check if the array contains the same object.

if the object exists {

} else {
  var addPrf = ModalHomeLine(titolo: nomeLinea, link: linkNumeroLinea, immagine : immagine, numero : titoloLinea)
  preferiti.append(addPrf)
}

Answer 1

Swift has a generic contains function:

contains([1,2,3,4],0) -> false
contains([1,2,3,4],3) -> true
