Build an iMessage Clone With Stream's Agent Skills

A tutorial explains how to use Stream Agent Skills, Stream Chat, Stream Video, SwiftUI, and the Stream CLI to build an iMessage-style iOS application with messaging and audio/video calling. It requires Xcode 26 or later, a Stream account, and the Stream CLI and Swift skills, which allow coding agents to install SDKs, retrieve current documentation, configure server-side resources, mint user credentials, and generate Swift code. The resulting app includes an inbox with channel previews, unread indicators, edit and filter controls, a message screen with a floating Liquid Glass composer, contact profiles, a four-tab navigation interface, and FaceTime-like call screens. Its architecture separates chat and video into singleton service files, uses the CLI to create demo users and one-to-one channels, initializes SDK clients at the application root, and configures permissions for camera, microphone, and photo-library access. The guide also describes customized Stream Video UI components for local video, call controls, incoming and outgoing call states, and call overlays, while highlighting that calls use shared Stream credentials and real-time WebRTC when answered.
