Smartlook records user interactions sessions. Every session has a single user and a single user can have multiple sessions. For more information on users, see Life Cycle, Session, User.

User identifier

To specify the user identifier:

Smartlook.instance.user.identifier = "sample-identifier"


Identifier restrictions

  • Cannot be null or empty
  • Maximum length is 120 characters.

User name and email

The name and email properties can be directly set using: = "John Doe" = "[email protected]"


Both and act as an alias. They are added to user properties under the name and email keys.

User properties

User properties can be added using a subscript or method:

Smartlook.instance.user["level"] = "Expert"
Smartlook.instance.user.setProperty("level", to: "Expert")

Opening a new user

The current user can be closed and a new user opened:



New user session

Opening a new user opens a new session. For more information on user sessions, see Lifecycle, Session, User.

User URL

The URL of the currently recorded user can be obtained:

let userURL = Smartlook.instance.user.url


Nullability and shareability

The URL is only available when the SDK was able to communicate with the Smartlook backend. Otherwise, it is null.

The URL is not publicly sharable. You must log in to the dashboard.

User Notification

A notification can be observed to listen to the user URL changes.

NotificationCenter.default.addObserver(forName: User.urlDidChangeNotification, object: nil, queue: nil) { note in
   // Called when session URL changes
