RLMLogger

Objective-C

@interface RLMLogger : NSObject

Swift

class RLMLogger : NSObject

RLMLogger is used for creating your own custom logging logic.

You can define your own logger creating an instance of RLMLogger and define the log function which will be invoked whenever there is a log message. Set this custom logger as you default logger using setDefaultLogger.

RLMLogger.defaultLogger = [[RLMLogger alloc] initWithLevel:RLMLogLevelDebug
                                           logFunction:^(RLMLogLevel level, NSString * message) {
    NSLog(@"Realm Log - %lu, %@", (unsigned long)level, message);
}];

Note

By default default log threshold level is RLMLogLevelInfo, and logging strings are output to Apple System Logger.
