Get n random objects (for example 4) from nsarray

Question

I have a large NSArray of names, I need to get random 4 records (names) from that array, how can I do that?

Answer 1

If you prefer a Swift Framework that also has some more handy features feel free to checkout HandySwift. You can add it to your project via Carthage then use it like this:

import HandySwift    

let names = ["Harry", "Hermione", "Ron", "Albus", "Severus"]
names.sample() // => "Hermione"

There is also an option to get multiple random elements at once:

names.sample(size: 3) // => ["Ron", "Albus", "Harry"]

I hope this helps!
