Keep your Xcode AI
coding while you sleep.

Claude, GitHub Copilot, Codex, and other AI assistants in Xcode stop when they hit a usage limit — and stay frozen until you're back. XcodeSentinel schedules a prompt for when the limit resets, so your AI picks up exactly where it left off.

Download XcodeSentinel

Free, open source, Developer ID signed & notarized.

macOS 15 (Sequoia) or later required

⬇ Download .dmg

You kick off a long Claude, Copilot, or Codex coding session in Xcode at 11 PM. The usage limit resets at 4:00 AM — but you'll be asleep. Without XcodeSentinel, the session sits frozen until 9 AM when you finally open your laptop.

With XcodeSentinel: schedule a send for 4:10 AM and Claude picks up exactly where it left off — while you sleep.

How It Works

🛑
Session Stalls
Your AI hits the usage limit, needs "Continue", or you simply want a message sent at a future time.
→
⏱
Scheduled Send
XcodeSentinel checks your schedules every 30 seconds and sends your message to the AI panel at the exact time you set.
→
🚀
Session Resumes
The AI receives the message and continues coding. You get a macOS notification — or a phone push if you configure a webhook.

Features

🗓️ Scheduled Sends

Set any message to be typed into your Xcode AI panel (Claude, Copilot, Codex, etc.) at a specific time. Repeat daily, on weekdays, or just once. Survives sleep and restarts.

📋 Execution Log

Every send attempt is logged with timestamp and outcome (Sent, Failed, Deferred). View the last 50 entries from the menu bar — no digging through Console.

🔒 Screen-Lock Aware

Enable "Prevent screen lock" and the app holds a display-sleep assertion while schedules are pending, so the session fires even overnight.

📲 Away Notifications

Webhook support with ntfy / Pushover / Discord / Slack presets. Sends only the target name and status — never chat text or source code.

🔬 AX Inspector

Dump any window's Accessibility tree to JSON. Export for bug reports or regression fixtures when Xcode updates change the UI structure.

⚡ Lightweight

Menu-bar app, no Dock icon. Pure Swift 6, zero external dependencies. Accessibility API only — no Screen Recording permission needed.

Install in 3 Steps

1

Download the DMG

Grab the latest .dmg from GitHub Releases. Double-click to mount it, then drag XcodeSentinel to your Applications folder.

2

Launch — it lives in the menu bar

No Dock icon. XcodeSentinel appears as a clock icon (⏱) in the menu bar. Click it to open the schedule list.

3

Grant Accessibility permission

On first run, it opens System Settings → Privacy & Security → Accessibility. Toggle XcodeSentinel on. No Screen Recording or Full Disk Access needed.

Important Notes

⚠️ XcodeSentinel does not bypass or extend any usage limit. It only sends a message you pre-wrote — after the limit has already cleared. Limits still apply normally.

🎯 Scope is Xcode AI panels only. This app works with any AI chat panel inside Xcode (Claude, Copilot, Codex, etc.) that exposes an Accessibility API text input. Terminal-based tools (Claude Code CLI, etc.) and VS Code extensions are out of scope — those run outside Xcode and have their own auto-continue features.

🏪 Not on the Mac App Store. An app that uses the Accessibility API to drive another app cannot ship in the App Sandbox. Downloads come from GitHub Releases only.

🔑 v0.1.0 is an unsigned developer preview. First open: right-click → Open, or after copying run xattr -cr /Applications/XcodeSentinel.app in Terminal. Notarized signed release planned when Apple Developer ID credentials are configured in CI.

Requirements

  • macOS 15 (Sequoia) or later
  • Xcode with an AI integration enabled (Claude, Copilot, Codex, etc.)
  • Accessibility permission (see Privacy for what's accessed)
