Swift program to implement string interpolation

Here, we are going to learn how to implement string interpolation in Swift programming language?
Last Updated : June 10, 2021

Problem Solution

Here, we will implement string interpolation. String interpolation is used to create a string that contains the values of constants, variables, literals, and expressions.

Program/Source Code

The source code to implement string interpolation is given below. The given program is compiled and executed successfully.

// Swift program to demonstrate the
// string interpolation

var intVar   = 10
var floatVar = 3.142

var str = "Int value: \(intVar), Float value: \(floatVar)"

print(str)

Output

Int value: 10, Float value: 3.142

...Program finished with exit code 0
Press ENTER to exit console.

Explanation

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

Here, we created two variables intVar, floatVar that are initialized with 10, 3.142 respectively.

Then we interpolated variables into the string and printed the result on the console screen.
