Select a Random String from an Array

// Select a random string from an array and print the result
let verbs = ["walk", "jump", "run", "swim", "dance"]                                                                                                                                                                                                                                                                                                                
let verb = verbs[Int.random(in:0..<verbs.count)]                                                                                                                                                                                                                                                                                                                    
print(verb)

// Select a random string from an array and print the result (with syntactic sugar)
let verbs = ["walk", "jump", "run", "swim", "dance"]
if let verb = verbs.randomElement() {// Note: randomElement() returns an optional string
    print(verb)
}

Shuffle an Array

let verbs = ["walk", "jump", "run", "swim", "dance"]
let shuffledVerbs = verbs.shuffled()
for verb in shuffledVerbs {
    print(verb)
}
