To use an environment variable in Swift, you can access it using the ProcessInfo class, which provides access to the environment variables of the current process. Here's a simple example:

import Foundation

if let myVariable = ProcessInfo.processInfo.environment["MY_ENV_VARIABLE"] {
    print("Environment variable value: \(myVariable)")
} else {
    print("Environment variable not set.")
}

In this code, ProcessInfo.processInfo.environment is a dictionary where the keys are the names of the environment variables, and the values are the corresponding values. You can access an environment variable by its name, such as "MY_ENV_VARIABLE" in this example.

A Swift Tour: Explore Swift’s features and design

Learn the essential features and design philosophy of the Swift programming language. We’ll explore how to model data, handle errors, use protocols, write concurrent code, and more while building up a Swift package that has a library, an HTTP server, and a command line client. Whether you’re just beginning your Swift journey or have been with us from the start, this talk will help you get the most out of the language.

Go small with Embedded Swift

Embedded Swift brings the safety and expressivity of Swift to constrained environments. Explore how Embedded Swift runs on a variety of microcontrollers through a demonstration using an off-the-shelf Matter device. Learn how the Embedded Swift subset packs the benefits of Swift into a tiny footprint with no runtime, and discover plenty of resources to start your own Embedded Swift adventure.

Bring context to today’s weather

Harness the power of WeatherKit to get detailed weather forecast data such as precipitation amounts by type, cloud cover by altitude, or maximum wind speed. Find out how you can summarize weather by different parts of the day and highlight significant upcoming changes to temperature or precipitation. Understand how you can compare current weather to the past through our Historical Comparisons dataset and dive into historical weather statistics for any location in the world. We’ll also explore how you can do all of this faster with our Swift and REST APIs.

Migrate your app to Swift 6

Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.

What’s new in Swift

Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
