Open Source Swift AI Coding Tools

Coucou is an open-source desktop and iPhone companion for monitoring AI coding agents without constantly switching back to a terminal. On macOS it lives around the MacBook notch, while Windows and Linux versions place the interface at the top of the screen. It tracks sessions from Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Copilot CLI, and other agents. Permission requests and questions can be approved or answered directly from the companion interface. Users can inspect live file edits, jump to the correct terminal, drop files for context, and chat with cloud or local models. Its iPhone companion extends alerts and controls to the Lock Screen, Dynamic Island, widgets, and Siri.

CodexBar is a lightweight macOS utility that displays real-time usage statistics for AI coding tools such as OpenAI Codex and Claude Code directly from the system menu bar. The application is designed to give developers quick visibility into token consumption and activity without requiring them to open web dashboards or log into provider portals. Built in Swift with a native macOS interface, it integrates seamlessly into the desktop environment and emphasizes minimal overhead. The tool is particularly useful for monitoring usage limits, managing costs, and keeping track of AI-assisted development sessions. CodexBar focuses on simplicity and fast feedback, presenting key metrics in an always-accessible format. Overall, it functions as a convenient observability companion for developers who rely heavily on AI coding assistants.

ClaudeBar is a macOS menu bar utility that helps developers and power users monitor their AI coding assistant usage quotas from a lightweight system tray interface. Rather than constantly running CLI commands or navigating web dashboards, users can glance at their quota statistics for services like Claude, Codex, Gemini, GitHub Copilot, and Antigravity directly from the menu bar. The application provides real-time tracking of session, weekly, and model-specific usage percentages, using visual indicators such as color-coded progress bars to communicate when quotas are healthy, nearing limits, or depleted. It includes options to enable or disable monitoring for individual providers, supports multiple visual themes (including dark mode and a festive theme), and refreshes data at configurable intervals so users always have up-to-date information.

Copilot for Xcode brings GitHub Copilot’s AI-driven code suggestions directly into Apple’s Xcode IDE, giving iOS and macOS developers predictive completions, context-aware recommendations, and natural language assistance while they write Swift, Objective-C, and related code. It embeds seamlessly into the Xcode editor UI, offering completions as you type, including full lines or blocks of code derived from surrounding context and doc comments. Because the integration understands the structure of Xcode-based projects and Apple’s frameworks, suggestions are often tailored to platform idioms, APIs, and patterns used in Cocoa, UIKit, SwiftUI, and more. It also supports natural language prompts, letting developers ask for example code or explanations inline without leaving the IDE. The extension is designed to respect privacy and project scope, giving users control over when Copilot suggestions are enabled and how telemetry is shared.
