The tutorial provides a comprehensive guide to building an iOS group messaging application using Objective-C and PubNub, emphasizing the challenges and advantages of designing such an app on a new platform. The author chose to create a group chat client to address the lack of dedicated tools for efficient large-group communication. Initially challenging due to XCode and Objective-C's complexities, the development process became more manageable with the use of model-view-controller frameworks and storyboards. The app features include user-friendly interfaces with bubble-like message boxes and intuitive design elements, allowing users to easily add or remove group members. The PubNub Data Stream Network plays a crucial role in facilitating seamless message sending and receiving, with a selective-listening feature that empowers users to choose their group members. The tutorial also highlights the recent release of a redesigned iOS SDK and provides resources like a migration guide and a GitHub repository with all the code needed to get started.

PubNub has recently expanded its range of supported SDKs by introducing its new WebRTC SDK, designed to simplify the integration of WebRTC into applications enabled by PubNub. Alongside the SDK, PubNub has launched a prototype demo called PubShare to showcase the capabilities of the WebRTC API, and it provides a comprehensive tutorial and demo of WebRTC file sharing to help developers understand how to create PubNub+WebRTC applications. To access the API, developers must sign up for a PubNub account to obtain unique keys via the PubNub Developer Portal. The WebRTC API is hosted on GitHub, while the core PubNub service is accessible from its CDN. PubNub Channel Presence facilitates user visibility for file sharing, and signals are used to notify users of file sharing requests and responses. The tutorial offers step-by-step guidance and all necessary code to build a custom file-sharing application using PubNub and WebRTC.
