Logging

This Rive runtime includes logging capabilities to help with debugging. These logs are only for debugging purposes; nothing is sent over the network, and no personally identifiable information (PII) is logged.

The table below showcases the runtimes that support logging.

The new runtime does not yet include logging, but will be added in the near future.

RiveLogger.isEnabled = true // Enable logging; false by default
RiveLogger.levels = [.debug] // Filter logs; all by default
RiveLogger.categories = [.viewModel] // Filter categories; all by default
RiveLogger.isVerbose = true // Include verbose logs; false by default

Levels

Logs will be logged at various levels, which are similar to those of OSLogType . These levels can be used to additionally filter logs to be logged at certain levels only. Available levels are:

• Debug: most commonly used, to aid with debugging
• Info: logs that provide additional information
• Default: the default log level; however, many logs are debug level
• Error: used when an error occurs
• Fault: used when a critical (fatal) error occurs

Categories

Logs are split by categories; individual portions of the runtime are split into separate logs to support filtering. Available categories are:

• State machine: operations that occur within an active state machine, such as receiving events
• Artboard: operations that occur within an active artboard, such as advancing (verbose)
• View model: operations that occur within a loaded RiveViewModel , such as triggering / setting inputs
• Model: operations that occur within a loaded RiveModel , such as setting state machines / artboards
• File: operations that occur within a loaded RiveFile, such as asset loading
• View: operations that occur within a RiveView, such as player events (play / pause / stop / reset)

Verbose Logs

Certain logs are verbose, meaning they will stream logs consistently. Examples of these logs are view advances, and drawing validation. Verbose logs are disabled by default; see above for how to enable verbose logging.
