Adding the word “and” before the final item of an array in Swift

Question

I have a list of items in an array. The default output of the items is a simple list separated by commas. However, a proper sentence would include the word \"and\"

Answer 1

Try this code

    let myItem1: String = "Apple"
    let myItem2: String = "Bee"
    let myItem3: String = "Carrot"
    let myItem4: String = "Dog"

    let myArray = Set(arrayLiteral: myItem1, myItem2, myItem3, myItem4)

    //print("Item count:", myArray.count)
    print("Item list:", myArray.joinWithSeparator(", "))

    var joinedString : NSString =  myArray.joinWithSeparator(", ")

    let lastRangeOfComma = joinedString.rangeOfString(",", options: .BackwardsSearch)
    joinedString = joinedString.stringByReplacingCharactersInRange(lastRangeOfComma, withString: " and")
    print("\(joinedString)")

Hope this helps.
