How to assign values to multiple variables at once in Swift

Overview

We can assign values to multiple variables at once in a single statement in Swift. We need to wrap the variables inside a bracket and assign the values using the equal sign =. The values are also wrapped inside a bracket.

Syntax

(var1, var2, ...) = (val1, val2, ...)
Assigning multiple values to multiple variables in Swift

Parameters

  • var1, var2, ...: These are the variables we want to assign values to simultaneously.
  • val1, val2, ...: These are the values we want to assign to the variables.

Code

Let's look at the code below:

import Swift
// create some variables
var name = ""
var age = 0
var role = ""
var isMarried = false
// assign values at once
(name, age, role, isMarried) = ("Theodore", 200, "Software Deeveloper", true)
// print values
print(name)
print(age)
print(role)
print(isMarried)

Explanation

In the code above:

  • Lines 4 to 7: We create some variables.
  • Line 10: We assign values to multiple variables at once.
  • Lines 13 to 16: We print the values of the newly assigned variables.
