Apple Mail Extension for Auto-Suggest Text using OpenAI API

Apple Mail Extension for Auto-Suggest Text using OpenAI API Problem Description Develop an Apple Mail Extension application that integrates with OpenAI's GPT-based API to provide auto-suggestions for text while composing or replying to emails. The application should be efficient and user-friendly, allowing users to quickly generate relevant text based on the email thread. Features 1. The auto-suggestion tool can be activated manually using a keyboard shortcut (e.g., Cmd + Space). 2. The prompt sent to the OpenAI API includes the email thread to which the user is responding. If the email chain is too long, it should be truncated appropriately to fit within the API's character limit. 3. The tool should be capable of generating complete email responses based on the context provided. Acceptance Criteria 1. A self-contained Xcode project that runs successfully after configuring the OpenAI API key. 2. He/she should have experience working with Xcode and macOS projects, preferably with Mail app extensions. 3. The user experience should be minimalistic, with either a simple menu or system buttons to interact with the extension. 4. The code should not be published and must be shared privately. 5. He/she must be professional, meet deadlines, and respond promptly to messages. Technical Details 1. The application should be written in Swift programming language. 2. The code must be clear, concise, and well-documented to ensure maintainability and ease of understanding. 3. The application should handle API errors and edge cases gracefully, providing appropriate feedback to the user. 4. Network requests to the OpenAI API should be asynchronous to avoid blocking the main thread and ensure a smooth user experience. 5. The extension should follow Apple's Human Interface Guidelines for macOS and Mail app extensions. 6. Use of external libraries or dependencies should be minimized to reduce the project's complexity and potential maintenance issues. If required, popular and well-maintained libraries should be preferred. 7. The applicant should provide a README file containing clear instructions on how to set up, build, and run the project, along with any necessary information about configuring the OpenAI API key.
