Summary of Changes

Hello @DRadmir, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a comprehensive solution for integrating iCloud CloudKit synchronization capabilities into the application. It establishes a modular CloudStore component, defining clear protocols for data types that can be synchronized and for optional data transformation, including encryption. The core CloudSyncService provides robust functionality for managing data within iCloud, enhancing the application's ability to persist and retrieve user data securely across devices.

Highlights

• New CloudStore Module: A new CloudStore module has been introduced to facilitate iCloud CloudKit synchronization.
• Data Transformation Protocol: A DataTransformable protocol was added to support optional data transformations, such as AES-GCM encryption, before data is stored or after it is retrieved.
• Generic CloudSyncable Protocol: A CloudSyncable protocol was defined to allow any identifiable and codable data type to be synchronized with CloudKit.
• CloudSyncService Implementation: A CloudSyncService actor was implemented to handle iCloud account status checks, saving, fetching, and deleting of CloudSyncable items in CloudKit.

Code Review

The pull request introduces a solid foundation for iCloud synchronization using CloudKit. It correctly leverages Swift concurrency with actors and provides a flexible encryption layer via the DataTransformable protocol. The use of AES-GCM for encryption is a secure and appropriate choice for this context. However, there are a few important areas for improvement: the fetch method needs to handle CloudKit pagination to ensure all records are retrieved, the deleteAll method can be optimized to avoid unnecessary data processing, and the default recordType implementation should be more resilient to code refactoring.
