# Lendair iOS Project

## Overview

Lendair is an iOS peer-to-peer lending application with real-time notifications, user profiles, and loan management.

## Current Active Work

**FRE-4686**: Add Notifications screen to Lendair iOS app

### Implementation Status

**Recovery:**
- FRE-4750: Issue recovery task (done - CTO)

**Completed/In Review:**
- FRE-4737: NotificationsView component (in_review - Code Reviewer)
- FRE-4738: Mark-as-read actions (in_review - Code Reviewer)

**Pending:**
- FRE-4739: MainTabView integration (todo - Senior Engineer)
- FRE-4740: Unread badge count (todo - Senior Engineer)

## Architecture

### Notification System
- **View Layer**: NotificationsView.swift, NotificationRowView.swift
- **ViewModel Layer**: NotificationsViewModel.swift (MVVM pattern)
- **Data Layer**: tRPC notifications router integration
- **Notification Types**: LOAN_APPROVED, LOAN_REJECTED, PAYMENT_RECEIVED, PAYMENT_DUE, NEW_LENDER, SYSTEM_UPDATE

### Key Files
- `Lendair/Views/NotificationsView.swift` - Main container with SwiftUI List
- `Lendair/Views/NotificationRowView.swift` - Individual notification row
- `Lendair/ViewModels/NotificationsViewModel.swift` - Data fetching and state management

## Technical Decisions

1. **MVVM Pattern**: Used for separation of concerns and testability
2. **SwiftUI List**: For efficient rendering of notification collections
3. **Pull-to-refresh**: Native Refreshable API for manual refresh
4. **Empty State**: Custom empty state view with friendly messaging
5. **Notification Types**: Enum-based system for type-safe notification handling

## Dependencies

- Backend: `web/src/server/api/routers/notifications.ts`
- Database: `web/src/server/db/schema.ts` (notifications table)

## Team Assignments

- **Founding Engineer**: FRE-4737, FRE-4738 (core UI and actions)
- **Code Reviewer**: Reviewing FRE-4737, FRE-4738
- **Senior Engineer**: FRE-4739, FRE-4740 (integration and polish)
