How can I add text to a label from two different arrays in swift chosen at Random

Question

I have created a label with a frame on the screen which displays the chosen text. I also have two different arrays for the first and last name.

let nameArray = ["Jacob", "Lenny", "George", "Linda", "Arthur"]
let lastNameArray = ["Shelby", "Knight", "Luiz", "Hamilton", "Dobson"]

when I use nameLabel.text = nameArray.randomElement() it works fine, but I want it to display both a random first name and a random last name from the given arrays within the same label. How would I go about doing this?

Answer 1

Just do the same thing but twice

nameLabel.text = "\(nameArray.randomElement()!) \(lastNameArray.randomElement()!)"

Answer 2

You can zip both array and then use random.

Here is solution

let nameArray = ["Jacob", "Lenny", "George", "Linda", "Arthur"]
let lastNameArray = ["Shelby", "Knight", "Luiz", "Hamilton", "Dobson"]
let combine = Array(zip(nameArray, lastNameArray))

let randomName = combine.randomElement() ?? ("", "")
nameLabel.text = randomName.0 + " " + randomName.1

Answer 3

I recommend this way, randomPerson even creates (5) unique full names and starts over when all names are expended.

let firstNames = ["Jacob", "Lenny", "George", "Linda", "Arthur"]
let lastNames = ["Shelby", "Knight", "Luiz", "Hamilton", "Dobson"]

var tempFirstNames = [String]()
var tempLastNames = [String]()

func randomPerson() -> String {
    if tempLastNames.isEmpty {
        tempLastNames = lastNames
        tempFirstNames = firstNames
    }
    let firstName = tempFirstNames.remove(at: Int.random(in: 0..<tempFirstNames.count))
    let lastName = tempLastNames.remove(at: Int.random(in: 0..<tempLastNames.count))
    return "\(firstName) \(lastName)"
}

And use it

nameLabel.text = randomPerson()
