I\'m really confused with the ways we create an array in Swift. Could you please tell me how many ways to create an empty array with some detail?

Answer 1

Swift 5

There are three (3) ways to create a empty array in Swift and shorthand syntax way is always preferred.

Method 1: Shorthand Syntax

var arr = [Int]()

Method 2: Array Initializer

var arr = Array()

Method 3: Array with an Array Literal

var arr:[Int] = []

Method 4: Credit goes to @BallpointBen

var arr:Array = []
