Send and receive Morse code with an iPhone's LED torch and camera.

One phone blinks a message with its torch; another points its camera at the light,
detects the flicker, and decodes it back to text. Both the Japanese kana (和文) and
Latin (欧文) code tables are supported.

## Requirements

- Xcode 26.3 or later
- iOS 26.0 or later
- **An iPhone.** The torch and the camera are the whole point, so neither sending nor
  receiving works in the Simulator. The app builds and launches there, but it cannot
  transmit or decode. `TARGETED_DEVICE_FAMILY` is iPhone only.

## Building

```sh
git clone https://github.com/atsuki-seo/MorseApp.git
cd MorseApp
open MorseApp/MorseApp.xcodeproj
```

There are no remote package dependencies — every module is a local package inside this
repository, resolved by relative path, so the clone is all you need.

To run on a device, set your own signing values on the `MorseApp` target:

- **Signing & Capabilities > Team** — the checked-in `DEVELOPMENT_TEAM` is empty
- **Bundle Identifier** — the device value is `com.example.MorseApp`; change it to
  something you own

The app asks for camera access on first use of the receiver. The torch needs no
permission.

## Modules

| Module | Contents |
|---|---|
| `MorseCoder/` | The code tables, encoding and decoding. Has no `import` at all |
| `PulseTiming/` | Blinking itself — time, on/off runs, threshold detection, unit-length estimation. Knows nothing about Morse |
| `MorseSignal/` | The bridge between blinking and code — transcription, reading, accumulation, the statutory sending speed |
| `MorseApp/Packages/Light/` | This device's light — lending the torch (`LightDevice`), sending (`LightSending`), receiving (`LightReceiving`) |
| `MorseApp/MorseApp/` | The SwiftUI app: transmitter, receiver and code-table screens |

The three packages at the root declare no `platforms:` and depend on nothing outside
themselves, so they build anywhere Swift does. `Light` depends on AVFoundation and
`UIApplication`, which is why it lives under the Xcode project rather than at the root.

Dependencies flow in one direction only.

```mermaid
graph TD
    MorseCoder --> MorseSignal
    PulseTiming --> MorseSignal
    PulseTiming --> LightDevice
    MorseSignal --> LightSending
    MorseSignal --> LightReceiving
    LightDevice --> LightSending
    LightDevice --> LightReceiving
    LightSending --> MorseApp
    LightReceiving --> MorseApp
```

Sending and receiving do not know about each other. They share one LED, and
`LightDevice`, which lends it out, sits underneath both.

## Tests

The three root packages are platform-independent, so `swift test` runs them anywhere:

```sh
(cd MorseCoder && swift test)
(cd PulseTiming && swift test)
(cd MorseSignal && swift test)
```

`Light` is iOS-only — `swift build` would compile it for the host and fail on
`import UIKit` — so its tests run through `xcodebuild` against a simulator:

```sh
cd MorseApp/Packages/Light
xcodebuild -scheme Light-Package -destination 'platform=iOS Simulator,name=iPhone 17 Pro' test
```
