[Compare
Source](https://redirect.github.com/Iterable/swift-sdk/compare/6.5.14...6.6.0)

##### Added

- Introduces support for Unknown user activation, a feature that allows
marketers to convert valuable visitors into customers. With this
feature, the SDK can:
- Fetch unknown user profile creation criteria from your Iterable
project, and then automatically create Iterable user profiles for
Unknown users who meet these criteria.
- Save information about a user's previous interactions with your
application to their unknown user profile, after it's created.
- Display personalized messages for Unknown users (in-app, push, and
embedded messages).
- Merge unknown user profiles into existing, known user profiles (when
needed).
- `IterableConfig` is updated with an `enableUnknownUserActivation` flag
that needs to be set to true to allow use of the unknown user activation
functionality
- Unknown user activation is currently in public beta. If you'd like to
learn more about it or discuss using it, talk to your Iterable customer
success manager (who can also provide detailed documentation).
- To learn more, read [Unknown User Activation: Developer
Docs](https://support.iterable.com/hc/sections/40078809116180).
