WeatherKit

Can I check if there is anyway we can integrate haze information into WeatherKit?

anyone know where can we source.

WeatherKit already includes haze as a WeatherCondition, so you can check weather.currentWeather.condition for .haze. CurrentWeather also has visibility, which gives you the visibility distance. Those tell you the reported condition, but they are not a particulate reading like PM2.5 or an AQI value. If you need that, you will need a separate air-quality data provider.
