long: coordinate?????!!!

Why do we need to include 'long:' before: 'coordinate.long' wihle we include 'lat:' 'before coordinate.lat' ?

forecastService.getForecast(coordinate.lat, long: coordinate.long){ (let currently) in if let currentWeather = currently { //Update UI }

In Swift, the name of the first parameter in a function is omitted by default. You can read more about it in Apple's Swift documentation under "Function Parameter Names." You can certainly add "lat:" in front of coordinate.lat if you want to add some clarity to the function declaration...it will still work fine!
