Enumeration Case

OS_LOG_TYPE_FAULT

Fault-level messages are always saved in the data store. They remain there until a storage quota is exceeded, at which point, the oldest messages are purged. Fault-level messages are intended for capturing system-level or multi-process errors only. If an activity object exists, logging at this level captures information for the entire process chain. Logging a message at this level is equivalent to calling the os_log_fault function.
