Hello à tous,
J’ai un petit soucis qui me fait tourner en rond sur un crash de mon app quand je recharge une TableView avec un message d’erreur qui me dit Fatal error: Index out of range. J’ai bien essayé de comprendre par moi même avec des print() à des moments clés, mais je ne trouve pas, du coup, je sollicite votre aide 
Cela vient TRÈÈÈÈÈÈÈÈÈÈS probablement du moment où j’appelle tableView.reloadData()
