in swift 5 you can use suffix for get objects from the last and use prefix for get objects from the first, here is an example:

let exampleArray = ["first text", "second text", "third text"]

let arr1 = exampleArray.suffix(2) // ["second text", "third text"]
let arr2 = exampleArray.prefix(2) // ["first text", "second text"]

The result is a slice, but you can coerce it to an Array if you need to.
