Sendbird UIKit 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 application. You can closely monitor the operation of the UIKit SDK and improve debug efficiency using our logging system.

Log types

Log types, or log levels, can be used to categorize and control log outputs. The following table lists five different log types for the logger in UIKit for iOS.



No logs recorded.


Logs what have caused failures in the specific events, but not an UIKit-wide failure.


Logs unexpected events which wouldn’t affect the operation of UIKit, but might cause problems.


Logs general events of UIKit.


Logs all detailed information of the events and activities, including info, warn, and error.

How to configure the log type

The default log type for iOS is none. You can set the log level through the setLogLevel() method in the SBUMain class. If you are developing your app in Swift, you can first set a single log type and use a logType array to specify all log types at once. In Objective-C, you can set a single log type and then use a bit mask to specify all log types at once.

// Output all logs.
// Output only specific logs.
SBUMain.setLogLevel([.error, .info])
