AvWeather is a Swift package allowing you to retrieve and use data from the Aviation Weather Center at aviationweather.gov.
(The example shows Metar, but TAF can be used as well)
import AvWeather
let avWeatherClient = AWCClient()
// send a request for METAR data for Boston Logan Airport (KBOS)
avWeatherClient.send(MetarRequest(forStation: "KBOS")) { response in
switch response {
case .success(let metars):
// do something with new METAR data
print(metars[0].rawText)
case .failure(let error):
// request failed
print(error.localizedDescription)
}
}
// send a request for METAR data at multiple stations
avWeatherClient.send(MetarRequest(forStations: ["KBOS", "KORD", "KLAX"])) { response in
switch response {
case .success(let metars):
// do something with new METAR data
print(metars[0].rawText)
case .failure(let error):
// request failed
print(error.localizedDescription)
}
}AWC distinguishes between international and US Sigmets. Both can be retrieved by AvWeather, and represented by one common Sigmet class, although with some different properties. Refer to the implementation in Sigmet.swift for details.
import AvWeather
let weatherClient = AWCClient()
//Configure the request for International or US Sigmets
weatherClient.send(SigmetRequest(type: .international)) { [weak self] response in
DispatchQueue.main.async {
switch response {
case .success(let sigmets):
//Do something with sigmets
...
case .failure(let error):
// request failed
let msg = AWCClient.messageIn(error)
print(msg)
}
}
}AvWeather can also be used in Swift Async/Await concurrency schemes:
(The example shows TAF, but Metar and sigmets can be used as well)
// Instantiate a client
let client = AWCClient()
// Configure the request using 1 or more stations
let request = TAFRequest(forStations: ["ESSA", "ENGM", "GCLP", "LFPG", "KJFK", "KLAX"], mostRecent: true)
do {
let tafs = try await client.send(request)
// do something with TAF data
print(tafs[0].rawText)
} catch {
// An error was thrown
print("Error thrown getting tafs: \(AWCClient.messageIn(error))")
}
