Adding items in an array to different array at certain index

Question

I have two arrays

var array1 = [Doc 1, Doc 2, Doc 3]
var array2 = [Part 1, Part 2, Part 3]

I want to put items in array2 in array1 at certain index(between Doc 1 and Doc 2) like following:

[Doc 1, Part 1, Part 2, Part 3, Doc 2, Doc 3]

I know how to put an array into another array at certain index. But I'm not familiar with this kind of case. Is there any builtin method I can use in Swift? I can make my own algorithm but would like to know first if there's any built method for this case.

You say "I know how to put an array into another array at certain index". Do you mean you want a function that says "insert items from array1 between items y and z in array2"? I don't think you'll find anything that specific in the standard library. — Zev Eisenberg

This should do the trick:

array1.insertContentsOf(array2, at: 1)
