Swift First Program

Swift is a powerful and intuitive programming language developed by Apple for building iOS, macOS, watchOS, and tvOS applications. In this tutorial, we will create our first Swift program and explore the basics of the language.

Syntax

Swift has a modern and concise syntax that makes it easy to read and write. Here is an example of the basic syntax for creating a "Hello, World!" program in Swift:

let greeting = "Hello, World!"
print(greeting)

Example

Here is our first Swift program that prints "Hello, World!" to the console:

print("Hello, World!")

Output

The output of this program is the string "Hello, World!" printed to the console.

Explanation

The above code is a simple Swift program that prints a string to the console using the print() function. In Swift, a string is a series of characters enclosed in double quotes. The print() function is a built-in function that prints its arguments to the console.

Use

Swift is used to develop a wide range of applications for Apple devices, including iPhone, iPad, Mac, Apple Watch, and Apple TV. With its modern syntax and powerful features, Swift is a popular choice for both beginner and experienced developers.
