I need help to find a script to picks a sentence from a list

Like picking a random element from an array?

@mikaelacaron

a random element from an array

Yes, I think so. Can you give me example code to do this? Thank you! (Thank you for the reply)

[roosterboy]

let array = ["String 1", "String 2", "String 3"]
let randomString = array.randomElement()

//but be aware that randomString is an Optional since you could call
//randomElement() on an empty array and it will return nil

[mikaelacaron]

You could also shuffle the array, and then choose the first element

@roosterboy

let array = ["String 1", "String 2", "String 3"]
let randomString = array.randomElement()

Thank you for the code, but it gives me an error. Can you help me fix it?

[mikaelacaron]

You need to set a variable for your randomElement and use the value

Also I would highly recommend going back to iOS foundations and learning more about how arrays work.
