Create a user for which you can make flag decisions and track events. The user context is returned as a runtime object that is not otherwise persisted. The purpose of this method is to set a user context once, so you don't have to specify the user each time you make a flag decision or track an event. You can define multiple user contexts.
SDK v3.7 and higher
This call creates a user context for flag decisions and events. You can call this method successfully on the Optimizely client instance, even when the instance is not fully configured yet.
The following table lists the required and optional parameters:
The ID of the user.
A map of custom key-value string pairs specifying attributes for the user that are used for audience targeting. See the following section for more details.
You can set custom audience attributes for the user, which you can then use to Target audiences. You can pass strings, numbers, Booleans, and nil as custom user attribute values. If you want to target audiences based on the version of your application that they're using, you can also pass in a string formatted as a semantic version, then define a
version audience condition in the Optimizely app.
During audience evaluation, note that if you don't pass a valid attribute value for a given audience condition—for example, if you pass a string when the audience condition requires a Boolean, or if you simply forget to pass a value—then that condition will be skipped. The SDK logs will include warnings when this occurs.
Returns an OptimizelyUserContext object. For details, see OptimizelyUserContext.
