Features

• Interaction Logging: Record meetings, calls, emails, and other interactions with contacts, each with date, duration, notes, and outcome tags.
• Contact Timeline: A chronological view of all interactions with a given contact, making it easy to recall conversation history before an important meeting.
• Smart Reminders: Set follow-up reminders per contact or interaction type, surfaced as local notifications.
• iCloud Sync: Core Data's NSPersistentCloudKitContainer syncs all data seamlessly across the user's devices via CloudKit.
• SwiftUI Throughout: The entire UI is built with SwiftUI, using the MVVM pattern with @StateObject, @ObservedObject, and @FetchRequest property wrappers.

Technical Highlights

The CloudKit integration was the most technically interesting aspect — setting up the CloudKit schema, handling merge conflicts in the sync layer, and managing private vs. public databases. Core Data's integration with SwiftUI through @FetchRequest and NSManagedObjectContext provides a clean, reactive data layer.
