# OSLogType

The various log levels that the unified logging system provides.

```
struct OSLogType
```

## Overview

A log level controls how and when the system writes a message to the unified logging system. To write a message with a specific log level, create a [`Logger`](/documentation/os/Logger) and call its [`log(level:_:)`](/documentation/os/Logger/log(level:_:)) method. Alternatively, call the method that corresponds to the desired log level, such as [`debug(_:)`](/documentation/os/Logger/debug(_:)) or [`fault(_:)`](/documentation/os/Logger/fault(_:)).

## Topics

### Getting Log Types

[`debug`](/documentation/os/OSLogType/debug)

The debug log level.

[`info`](/documentation/os/OSLogType/info)

The informative log level.

[`default`](/documentation/os/OSLogType/default)

The default log level.

[`error`](/documentation/os/OSLogType/error)

The error log level.

[`fault`](/documentation/os/OSLogType/fault)

The fault log level.

### Creating a Log Type

[`init(_:)`](/documentation/os/OSLogType/init(_:))

Creates a log type from the specified value.

[`init(rawValue:)`](/documentation/os/OSLogType/init(rawValue:))

Creates a log type from the specified raw value.

### Getting the Raw Value

[`rawValue`](/documentation/os/OSLogType/rawValue)

The log type’s raw value.
