# Environment variables

## What are Environment Variables?

**Note: Before using this feature, a developer must define the code that handles boot arguments.**

On iOS, *environment variables* refer to boot variables. The behavior of this feature changes depending on the predefined code in the app. After the code is changed, you can use this feature to pass specific values to the app. For example, you can use environment variables to:

- Change the server endpoint for each scenario
- Change the application state for each scenario

## App Prerequisites

To use this feature, the app must be able to handle boot variables. Below is a sample code in Swift. The value of `<Key>` in the sample code must be the same as the Key registered in Autify.

```
#if DEBUG 
    if ProcessInfo.processInfo.environment["<Key>"] ! = nil { 
        // Do something 
    } 
#endif
```

For more information on Swift's ProcessInfo class, please refer to Apple's official documentation.
