Introduction to JabberGuestSDK-iOS-10.5.3.748.zip

This 182MB development package (released April 2025) provides enterprise developers with tools to implement secure guest access workflows in iOS applications integrated with Cisco Webex infrastructure. Designed for organizations using Cisco Unified Communications Manager v15.3+ with Expressway Core/E edge deployment, the SDK enables GDPR-compliant external collaboration while maintaining Zero Trust security principles.

The ZIP archive contains Swift/Objective-C frameworks, API documentation, and preconfigured policy templates for iOS 16.4+ environments. It supports hybrid deployments across Webex Cloud and on-premises CUCM clusters, requiring Xcode 16.2+ for integration.
