Semicolons in Swift

Published May 30 2021

This tutorial belongs to the Swift series

In Swift, semicolons are optional.

You can write statements on separate lines, and you don’t need to add a semicolon:

let list = ["a", "b", "c"]
var a = 2

You can add a semicolon, but it adds nothing meaningful in this case:

let list = ["a", "b", "c"];
var a = 2;

But if you want to write more than one statement on the same line, then you need to add a semicolon:

var a = 2; let b = 3
