The RudderStack iOS SDK enables you to easily associate one identity with another using the Alias method. This method helps manage user identities successfully in some destinations. For example, in Mixpanel, the Alias method associates an anonymous user with an identified user after sign up. The iOS SDK allows you to group users specific to an organization by denoting an ID of the group (company, organization, account, project, or team) with which you want to associate your user. The Group call lets you record custom traits about the group, such as the industry or number of employees.
