Swift version: 5.6
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:
Another option is using the
+= operator, which is overloaded for arrays to combine elements:
first += second
The third option is to use a regular
+ to create a new array by combining two others:
let third = first + second
All three options produce the same resulting array, albeit with different approaches.
