Welcome to CaptureSDK for iOS Documentation

The CaptureSDK eases the communication between your application and a Socket Mobile scanner.

The Capture API provides a basic set of methods and delegate to manage one or more scanners.

A Capture Helper adds a thin layer on top of this basic API, to simplify the use of the most common operations.

Capture Helper is available in Swift and Objective-C Capture Helper.

If you want an overall presentation you can jump to Getting Started with CaptureSDK for iOS which describe the connection process, and the way Capture interacts with your application.

Noticeable change from version 2.0 (from 8th of October 2025)

There are 2 choices to connect and use our Bluetooth LE readers:

  • Install our Socket Mobile Companion app which takes care of the discovery and the selection of the reader to connect to.

  • Write some code to fit the Bluetooth discovery flow to your application’s design by creating an UI that starts and shows discovered devices and select them to be paired to your application.
