## Setup

### Project Configuration

1. Enable the **WeatherKit** capability in Xcode (adds the entitlement)
2. Enable WeatherKit for your App ID in the Apple Developer portal
3. Add `NSLocationWhenInUseUsageDescription` to Info.plist if using device location
4. WeatherKit requires an active Apple Developer Program membership

### Import

```swift
import WeatherKit
import CoreLocation
```

### Creating the Service

Use the shared singleton or create an instance. `WeatherService` conforms to
`Sendable`; keep app cache and UI state isolated separately.

```swift
let weatherService = WeatherService.shared
// or
let weatherService = WeatherService()
```

## Fetching Current Weather

Fetch current conditions for a location. Returns a `Weather` object with all
available datasets.

WeatherKit temperatures are `Measurement<UnitTemperature>` values; display them
with `.formatted()` so units and number formatting follow the user's locale.

```swift
func fetchCurrentWeather(for location: CLLocation) async throws -> CurrentWeather {
    let weather = try await weatherService.weather(for: location)
    return weather.currentWeather
}
