The AEPAssurance (3.x) extension is implemented purely in Swift and is compatible with the AEPCore swift SDK. To ensure a smooth transition from the AEPAssurance (1.x) SDK, there are no major changes on the API names or definition. For more details, follow the migration guide below for your Swift or Objective-C mobile application. If explanation beyond showing API differences is necessary, it will be captured as an info hint within that API's section.
