A developer shares how FlowDeck, a CLI tool for iOS development, replaced raw xcodebuild and Xcode's MCP bridge in their AI agent workflow. FlowDeck wraps xcodebuild, simctl, and devicectl behind a single consistent interface, returning structured JSON output that keeps agent context windows clean. Key features include one-time project config, structured build error output, app log streaming, and a UI simulator session that captures screenshots and accessibility trees every 500ms for agent-driven UI validation. The post covers setup with Cursor via an agent skill file and a short agents.md rule, and compares FlowDeck to XcodeBuildMCP, noting that FlowDeck's CLI approach lets developers run the same commands their agents run.
