Enumeration Case

OS_LOG_TYPE_DEBUG

Debug-level messages are only captured in memory when debug logging is enabled through a configuration change. They’re purged in accordance with the configuration’s persistence setting. Messages logged at this level contain information that may be useful during development or while troubleshooting a specific problem. Debug logging is intended for use in a development environment and not in shipping software. Logging a message of this type is equivalent to calling the os_log_debug function.
