Cannot subscript a value of type [String] with an index of type “UInt32”

Question

i\'ve been trying to create a code to generate random names. Here it is

import UIKit

 let arrayOfNames: [String] = [\"Giovanni\", \"Simone\", \"Francesco\",         


        

Answer 1

You should use an Int to access an array by index

Replace this

var casual1 = arc4random_uniform(7)
var casual2 = arc4random_uniform(7)

with this

var casual1 = Int(arc4random_uniform(7))
var casual2 = Int(arc4random_uniform(7))
