  • Appropriate for error conditions.

    Declaration

    Swift

    case error
    Show on GitHub

  • Appropriate for critical error conditions that usually require immediate attention.

    When a critical message is logged, the logging backend (LogHandler) is free to perform more heavy-weight operations to capture system state (such as capturing stack traces) to facilitate debugging.

    Declaration

    Swift

    case critical
