Swift: append Method

append Method in Swift:

When working with arrays, it’s possible that we’ll need to add more elements after they’ve been initialised. By calling the array’s append method, we can add a new element to the end of the array in Swift:

arrayName.append(value);

As an example, let’s say we have a shapes array:

var shapes = ["Circle", "Rectangle"];

We can add a new item "Triangle" to the end of the array as follows:

shapes.append("Triangle");
// [Circle", "Rectangle", "Triangle"]

Alternatively, we can use the addition assignment operator += to append an array of one or more items:

shapes += ["Triangle", "Square"];
// [Circle", "Rectangle", "Triangle", "Square"]
