Comment

let fruits = ["apple", "pear", "pear", "banana", "apple"]

let noDuplicates = Array(Set(fruits))	// ["apple", "pear", "banana"]
//This is super short and works very well. 
//It has one possibly big disadvantage and that is it loses the order of items. 
//If you don’t care about order, then it does not matter. 
// Otherwise just call sorted or sort as a last step like below
let orderedArray = noDuplicates.sorted()
