RemindWall

A cross-platform iOS and macOS (Catalyst) SwiftUI application that turns a device into a smart photo frame with reminder tracking, calendar integration, and NFC tag scanning.

Features

• Photo Slideshow - Select a photo album and display it as a slideshow with Ken Burns animation and live photo support
• Reminder Tracking - Track multiple people ("trackees") with configurable reminder schedules and days of the week
• NFC Tag Scanning - Associate NFC tags with trackees for quick check-in
• Calendar Integration - Display upcoming events from a selected calendar alongside the slideshow
• Screen Off Scheduling - Configure automatic screen dimming based on time-of-day rules
• External Monitor Brightness - DDC/CI brightness control for external monitors on macCatalyst

Requirements

• Xcode 26+
• iOS 26+ / macCatalyst 26+
• Swift 6.2

Getting Started

1. Clone the repository
2. Open RemindWall.xcodeproj in Xcode
3. Select the target:
   • RemindWall for macOS/macCatalyst
   • RemindWalliOS for iOS
4. Build and run

Project Structure

The app is split into two Xcode app targets that share all code through RWPureSwift, a local Swift Package:

Architecture

Built with The Composable Architecture (TCA) from Point-Free. Each feature is a @Reducer with clearly defined State, Action, and composition via Scope and store.scope().

Key libraries:

• swift-composable-architecture - State management and side effects
• swift-dependencies - Dependency injection and testability
• sqlite-data / swift-structured-queries - Type-safe SQLite database
• swift-tagged - Type-safe identifiers
• swift-concurrency-deadline - Async timeout utilities

Testing

Tests use Swift's native Testing framework (@Test, @Suite) and TCA's TestStore for feature testing.
