How to append one array to another array
Swift version: 5.4
There are three ways of adding one array to another, and you can use whichever syntax you prefer.
First, make a couple of test arrays to work with:
var first = ["John", "Paul"]
let second = ["George", "Ringo"]Note: I made the first array mutable so we can join the second array to it.
One option for joining arrays is the append(contentsOf:) method, used like this:
first.append(contentsOf: second)Another option is using the += operator, which is overloaded for arrays to combine elements:
first += secondThe third option is to use a regular + to create a new array by combining two others:
let third = first + secondAll three options produce the same resulting array, albeit with different approaches.
