How do you create an empty array in Swift?

Answer 1

In order to create an empty array, you need to declare the type of the elements that are going to be in the array. For example:

var myIntArray = [Int]()

var myStringArray = [String]()

or

var myIntArray: [Int] = []

var myStringArray: [String] = []

If you need to assign an empty array to an existing variable, you can just use the square bracket notation since the existing variable will already have its type declared:

myIntArray = []

myStringArray = []
