The Mobile SDK provides functionality that enables iOS applications to
call the public REST API on a ServiceNow instance.
Using the [NowAPIService](https://servicenow-prod.fluidtopics.net/Gr1Q4dzJQJ291KR8~xiXQg#NowAPIServiceiOSAPI "The NowAPIService class provides functions that enable you to perform requests to a specified ServiceNow REST API.") API you can interact with any of the base ServiceNow public [REST APIs](https://servicenow-prod.fluidtopics.net/enjkhEuAw9paPBNoW_8S3Q "Use REST interfaces to access data on your instance."), or create custom REST APIs within the instance and call those from your iOS application.
