# debug

The debug log level.

## Declaration

```swift
static let debug: OSLogType
```

## Discussion

Discussion Logging a message of this type is equivalent to calling the os_log_debug function. Use this level to capture information that may be useful during development or while troubleshooting a specific problem. The system only captures debug-level messages in memory when you enable debug logging through a configuration change, and purges them in accordance with the configuration’s persistence setting.
