SwiftBindings.Apple.WeatherKit

SwiftBindings.Apple.WeatherKit

Native .NET bindings for Apple's WeatherKit framework — current conditions, hourly and daily forecasts, severe-weather alerts, and historical data. These are not Objective-C proxy wrappers; they use .NET 10's native Swift interop for direct, high-performance calls into Swift APIs from C#.

📖 Full usage guide → — the complete fetch path (WeatherService → Weather → current/hourly/daily forecasts), reading Measurement<T> values, conditions/precipitation/wind/UV/moon enums, alerts, attribution, and the APIs that aren't bound yet.

Installation

dotnet add package SwiftBindings.Apple.WeatherKit

Requirements

• .NET 10.0+
• Target framework: net10.0-ios26.2 (or -macos26.2 / -maccatalyst26.2 / -tvos26.2) or higher. The package is compiled against the iOS 26.2 SDK supplement, so your app's <TargetFramework> platform version must be ≥ 26.2 to restore it — an explicit lower TPV (e.g. net10.0-ios18.0) or a bare net10.0-ios whose installed workload defaults below 26.2 fails restore with NU1202. This is the compile-SDK pin, not your app's deployment minimum.
• Deployment minimum is separate — set your app's real minimum OS with <SupportedOSPlatformVersion> (independent of the TFM above). Individual APIs that need a newer OS at runtime are gated by generated [SupportedOSPlatform] attributes; the C# compiler flags a call that isn't valid for your target.
• macOS host for development
• WeatherKit capability enabled and a paid Apple Developer Program membership (WeatherKit usage is metered and requires entitlement)

Usage

using WeatherKit;

var service = WeatherService.Shared;

// Get current attribution (logo + URL link required by Apple's terms)
var attribution = await service.GetAttributionAsync();

// Localised condition / phase descriptions
var phase = MoonPhase.Full.GetDescription();
var direction = Wind.CompassDirectionKind.North.GetDescription();

Iterating a forecast

Forecast<T> projects to IReadOnlyList<T>, so the standard C# enumeration shape just works:

// `weather` is an instance returned by WeatherService.GetWeatherAsync(...)
foreach (var hour in weather.HourlyForecast)
{
    Console.WriteLine($"{hour.Date}: {hour.Temperature}");
}

var firstDay = weather.DailyForecast[0];
var dayCount = weather.DailyForecast.Count;
