Static Arrays in Swift

When we're dealing with large amounts of data, we want to make sure we can organize and manage it properly.

In Swift, we use arrays to store several pieces of data in one place. The items in an array must be of the same data type.

A static array or fixed array is an array for which the size / length is determined when the array is created and/or allocated.

Creation:

Swift has no separate fixed-size array type. We create an array with a set number of items by specifying the element type and a repeating initial value (a let array can never change size):

let arrayOfStrings = [String](repeating: "", count: 3)

In this program we created an array named arrayOfStrings that consists of 3 String items.

These 3 items are "" (empty string, no value given yet) initially.

Creation & Initialization:

There is a way to initialize an array at creation by using the = operator with an opening bracket, end it with a closing bracket, and put a comma between each entry, like this:

var arrayOfStrings = ["AlgoCademy", "coding", "static arrays"]

We created an array named arrayOfStrings which consists of 3 String items: "AlgoCademy", "coding" and "static arrays".
