ChatGPT iOS Assistant Integration

I want a seamless way to interact with ChatGPT on my iPhone so it can handle the everyday tasks I normally juggle myself. The assistant must be able to:

• Read incoming Messages and draft/send replies on my behalf
• Add, edit, or cancel Calendar events in the native Calendar app
• Create, modify, and mark off items in the Reminders app

Both voice and text interaction matter to me. If I’m walking, a simple spoken request should trigger the same flow as typing inside the app. You’re free to lean on Siri Shortcuts, a custom SwiftUI interface, or any other iOS-approved method—as long as the experience feels native and secure.

I’m happy for you to leverage the OpenAI API, Core ML, CallKit, or Notification Service Extensions where helpful, but keep everything within Apple’s guidelines so TestFlight distribution (and eventual App Store approval) remains possible.

Deliverables I’d like to see:
• Xcode project (Swift/SwiftUI) with clean, well-commented code
• Setup instructions that walk me from API key entry to on-device testing
• A short demo video showing voice and text flows in action

I’ll test on the latest public iOS version. If all core functions work reliably and privacy is respected, we’re done—though I’m open to ongoing iterations afterward.
