Logger

Sendbird Chat SDK for iOS offers a logging system that allows you to keep track of a number of events and activities including data flow, error, and information while running your app. You can closely monitor the operation of the Sendbird SDK and improve debug efficiency using our logging system.

Log levels

Log levels can be used to categorize and control log outputs. The following table lists the five different log levels available in the logger in Sendbird Chat SDK for iOS.

List of log levels

Level	Description
none	No logs recorded.
error	Logs things that have caused failures in specific events, but not an SDK-wide failure.
warn	Logs unexpected events which doesn't affect the operation of Chat SDK, but might cause problems.
info	Logs general events of the Chat SDK.
verbose	Logs all the details of the events and activities, including log messages in `error`, `warn`, and `info`.

How to configure the log level

The default log level set for Sendbird Chat SDK for iOS is none, which means that the Sendbird SDK keeps logs of warning messages. You can configure logging through the unified SendbirdLogger as follows.

Swift

// Set the log level for Chat SDK.
SendbirdLogger.setLevel(.verbose, for: .chat)

// Set the log level for all Sendbird SDKs.
SendbirdLogger.setLevel(.error)

Note: SendbirdChat.setLogLevel(_:) and InitParams.logLevel are deprecated. Use SendbirdLogger.setLevel(_:for: .chat) instead. If SendbirdLogger.setLevel(...) has already been called, legacy log level settings are ignored.

List of parameters

Parameter name	Type	Description
level	enum	Specifies the severity level of the log to retrieve. One takes precedence over the other in the order of `.none`, `.error`, `.warning`, `.info`, and `.verbose`.
