You can go like this.

var contactsname = [(String,String)]()//firstname,lastname
contactsname = [("alex","joe"),("catty","drling"),("alex","fox"),("asta","alex")]
let key = "alex"

If you want to exact match the search name either with First name or Last name

let filterArray = contactsname.filter { $0.0 == key || $0.1 == key }

If you want to check First name and Last name contains specific string for that you can use contains

let filterArray = contactsname.filter { $0.0.contains(key) || $0.1.contains(key) }
