How to copy end of the Array in swift?

Question

There must be some really elegant way of copying end of the Array using Swift starting from some index, but I just could not find it, so I ended with this:

f         


        

Answer 1

You can use suffix:

let array = [1,2,3,4,5,6]
let lastTwo = array.suffix(2) // [5, 6]

As mentioned in the comment: This gives you an ArraySlice object which is sufficient for most cases. If you really need an Array object you have to cast it:

let lastTwoArray = Array(lastTwo)
