# OperatingSystemVersion

A structure that contains version information about the currently executing operating system, including major, minor, and patch version numbers.

```
struct OperatingSystemVersion
```

## Overview

Use the [`ProcessInfo`](/documentation/Foundation/ProcessInfo) property [`operatingSystemVersion`](/documentation/Foundation/ProcessInfo/operatingSystemVersion) to fetch an instance of this type. You can also pass this type to [`isOperatingSystemAtLeast(_:)`](/documentation/Foundation/ProcessInfo/isOperatingSystemAtLeast(_:)) to determine whether the current operating system version is the same or later than the given value.
