Swift: How to use an Array to Randomly Select a String

Advertisement

If you wish to make an app that randomly selects a word or a phrase, then you’ll need to use an array.  An array is a group of strings, numbers, or anything else.

Such as:

let array = [“Heads”,”Tails”]

Since we want to randomly select a word from this array, we need to use the arc4random statement, like so:

let randomIndex = Int(arc4random_uniform(UInt32(array.count)))

Then finally we want to print the results:

print(array[randomIndex])

Now lets put the above altogether in code:

import UIKit
import Foundation

let array = [“Heads”,”Tails”] let randomIndex = Int(arc4random_uniform(UInt32(array.count)))
print(array[randomIndex])
