ArraySlice in Array Swift [duplicate]

问题:

This question already has an answer here:

• In Swift, Array [String] slicing return type doesn't seem to be [String] 5 answers

after using the prefix method on an Array I get what is called an arraySlice. How can I transform this into an Array?

I am trying to fetch Ints from FacebookGraphApi then asking for the first 3 (prefix(3)) and trying to add them into a new array.

Thank you in advance

Just initialize a new Array with the slice:

let arr1 = [0,1,2,3,4,5,6,7]
let slice = arr1[2...5]
let arr2 = Array(slice)
