Logging

The Didomi SDK on iOS will log various informational and error messages.

As recommended by Apple, we use two mechanisms for logging:

• NSLog for iOS 9

• os_log for iOS 10+

Formats

iOS 9 - NSLog

Messages logged with NSLog use the format: Didomi - {LEVEL} - {Message}

Example: Didomi - ERROR - Didomi SDK is not ready

iOS 10+ - os_log

Messages logged with os_log use the type type to indicate the level and the following information:

• Subsystem: Bundle.main.bundleIdentifier or io.didomi.sdk if the bundler identifier is not available

• Category: Didomi

Example:

Levels

We use the standard log levels supported by os_log: debug, error, info, and fault.

You can decide what level of logs should be displayed by the SDK by calling the setLogLevel function:

import os

...

Didomi.shared.setLogLevel(minLevel: OSLogType.debug.rawValue)
Didomi.shared.setLogLevel(minLevel: 2)
Didomi.shared.initialize(...)

Make sure that the call to setLogLevel is done before the call to initialize or some messages will be logged at the wrong level.

If your app supports iOS 9, use the actual value of the error level instead of OSLogType:

Level	Value
info	1
debug	2
error	16
fault	17
