Using WeatherKit I want to get a 5-day forecast starting tomorrow, however, I only get 4 elements in the forecast. What am I missing here? public func updateWeather()async{ guard locationManager.location != nil else {locationManager.updateLocation(); return} if self.needsUpdating{ let startOfToday = Calendar.current.startOfDay(for: Date()) let endOfToday = startOfToday+24*3600 let firstDay:Date = endOfToday+1 let lastDay:Date = firstDay+(5*24*3600) futureWeather = try? await WeatherService.shared.weather(for: locationManager.location!, including: .daily(startDate: firstDay, endDate: lastDay) ) } }

Is there a means of accessing historical averages from WeatherKit? I imagine it would be monthly averages. Apple's Weather app recently introduced "Averages" – both daily and monthly. I'm wondering if this data is derived from WeatherKit. I'm also curious if there exists an API available to developers that hasn't made its way into the documentation yet, or if there are plans for making "averages" available to developers in upcoming improvements to WeatherKit.

This is a app for weather in which i used weatherkit.I have added "privacy - Location when in Usage Description in info of project and also enabled location in features of simulator to Apple.After doing all this ,still the permission message for location is not appearing in app in simulator.Following is my code: import CoreLocation import UIKit //final means this class will not be subclassed final class ViewController: UIViewController, CLLocationManagerDelegate { let locationManager = CLLocationManager() //to access weather data let service = WeatherService() override func viewDidLoad() { super.viewDidLoad() setupView() getUserLocation() } func getUserLocation(){ locationManager.delegate = self locationManager.requestWhenInUseAuthorization() locationManager.startUpdatingLocation() } func getWeather(location : CLLocation){ //asynchoronus task Task { do { //if it throws error //await tells to wait until function gives results let result = try await service.weather(for: location) print("Current : "+String(describing: result.currentWeather)) print("Daily : "+String(describing: result.dailyForecast)) print("Hourly : "+String(describing: result.hourlyForecast)) } catch { //it will be excecuted print(error.localizedDescription) } } } func setupView(){ } func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { guard let location = locations.first else { return } locationManager.stopUpdatingLocation() getWeather(location: location) } func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) { switch status { case .denied: print("location permission denied") case .authorizedWhenInUse, .authorizedAlways : manager.startUpdatingLocation() print("Location Permission Granted") case .notDetermined : print("location Permission not determined") default: break } } }

I created my own service to generate a JWT for WeatherKit. When I use this JWT in Postman it works as expected. However, if I use it in my React application I get a 403 CORS pre-flight check error. What this essentially means is by nature, Safari - before doing the GET call with Authorization header - it does a preflight check OPTIONS call without headers, to check if the service will accept the request. Unfortunately this generates a 403 error instead of an 200, so the GET Call with Authorization header cannot be made. Is this by design to prevent webfrontends from accessing the API or is this a bug I encountered? Thank you!

Hi, We have been using DarkSky's API for a few years now and we've always been able to pull data for at least 3 years prior to the current date. With WeatherKit, we are seeing that data is only available for the last 2 years. I've seen a few posts confirming this, but I'm curious if we will always be limited to 2 years of data or if this is a temporary situation and as time goes on, WeatherKit will have more and more historical data available? Another way to put it is will Apple always delete any data older than 2 years or will they start to build up an archive so in 10 years from now, they will have 12 total years of data (given they have 2 years right now). Thanks!

My app has been using WeatherKit via its REST API for months with success. Suddenly, the weatherkit API only returns to me "reason" : "NOT_ENABLED" now. I am unsure why it is suddenly telling me WeatherKit is not enabled?

System status shows WeatherKit as available, but currently all calls returns status 401 with the response body containing {"reason": "NOT_ENABLED"}. We have been running the exact same code in production since March 2023. Nothing changed. The system just started returning errors. Is that happening for anyone else?

I've received a forecast with non-zero precipitationChance and zero precipitationIntensity. Is this expected? How should I interpret the data? { "forecastStart": "2023-09-02T02:00:00Z", "cloudCover": 0.55, "conditionCode": "PartlyCloudy", "daylight": false, "humidity": 0.92, "precipitationAmount": 0, "precipitationIntensity": 0, "precipitationChance": 0.31, "precipitationType": "clear", "pressure": 1017.56, "pressureTrend": "steady", "snowfallIntensity": 0, "snowfallAmount": 0, "temperature": 12.56, "temperatureApparent": 12.22, "temperatureDewPoint": 11.26, "uvIndex": 0, "visibility": 23505.2, "windDirection": 233, "windGust": 6.17, "windSpeed": 2.82 }

Could somebody please point me to the project download mentioned in Novall Khan’s “Meet Weatherkit” presentation? I’d additionally or alternatively be interested in any working examples for using the rest API, eg in Python, to access Weatherki. thanks, Rob

What is the highest level of location precision achievable with the WeatherKit API? When latitude and longitude are given up to the fifth decimal place, the precision is around 1 meter. Could this ever be more accurate than providing the lat/long to the fourth decimal place, which has a precision of about 10 meters?

Hello - migrated from darksky to WeatherKit in April of this year. With some difficulty finally got the REST API to work via the following resources: https://developer.apple.com/weatherkit/get-started/ which is horribly inadequate for JWT instructions. So i also used: https://dev.iachieved.it/iachievedit/weatherkit-rest-api/ which was quite helpful. As stated, in April i managed to get this working. About a week ago it stopped working. The response from my calls are 401 Unauthorized in the header and { "reason": "NOT_ENABLED" } in the body. I believe the key i created expired and thus WeatherKit stopped responding. So i tried to re-enable access using the same Apple key and a new JWT signature. That did not seem to work, so i removed the old key and created a new one. Downloaded the p8 file and used openssl on my ubuntu server to create pem and pub files for the jwt token. Still nothing. I have tried almost all combinations of keys and ID #s in the JWT.io console that i can think of. Importantly, nowhere in the official Apple documentation does it say what parameters the key creation and expiry dates can be. Does the key creation date have to match the date the key was created in Apple Developer Console??? What expiry dates are valid???? No idea. I have submitted a code level request, but they punted me to feedback which apparently does nothing. Still no resolution, nor have i been contacted once by an Apple representative. This is what my $200 developer fee gets me?! Unacceptable. If anyone has any idea on how to resolve this issue and/or create valid jwt tokens easier (via PHP preferably), i'm all ears. Thanks, airyt

Hi I upgraded my Mac to test the new os and iOS 17. But I have problems with the weather kit on the app. WeatherKit enabled as app service and capability there was no issue with the iOS 16. What could be the problem? import Foundation import WeatherKit class WeatherKitManager: ObservableObject { @Published var weather: Weather? @Published var isFetchingWeather = false func getWeather(latitude: Double, longitude: Double) async { do { let receivedWeather = try await WeatherService.shared.weather(for: .init(latitude: latitude, longitude: longitude)) DispatchQueue.main.async { self.weather = receivedWeather } } catch { fatalError("\(error)") } } var symbol: String { weather?.currentWeather.symbolName ?? "xmark.app" } var temp: String { if let temp = weather?.currentWeather.temperature.converted(to: .celsius) { let formattedTemp = String(format: "%.1f", temp.value) return "\(formattedTemp)°C" } else { return "Yükleniyor..." } } } Errors here Ceyehat/WeatherKitManager.swift:22: Fatal error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" Encountered an error when fetching weather data subset; location=<+37.78583400,-122.40641700> +/- 0.00m (speed -1.00 mps / course -1.00) @ 06/06/2023, 5:32:55 PM GMT+03:00, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"

Next hour rain data is not available for US.

Is anyone else experiencing issues with the REST API today? I'm getting very slow response times (again.)

I'm not able to inspect WeatherKit objects like HourWeather and CurrentWeather using the Xcode debugger and breakpoints. When I pause on a breakpoint and try something like po hours where hours is a [HourWeather] I get a debugger error like Couldn't lookup symbols: type metadata accessor for WeatherKit.HourWeather. Is there something about WeatherKit that prevents the debugger from printing out its objects?

My pipeline broke today as new fields were added for the current weather dataset: cloudCoverLowAltPct cloudCoverMidAltPct cloudCoverHighAltPct I presumed new fields would only be released in a new version of the API? Is there any way to use a specific version of the API that will not be subject to change? The current weather REST API docs are here, which don't include these fields: https://developer.apple.com/documentation/weatherkitrestapi/currentweather/currentweatherdata

When I'm using the following code into the simulator it gives the wanted result: Button {                 Task {                     localWeather = try await WeatherService.shared.weather(for: CLLocation(latitude: 52.5153, longitude: 6.08565), including:  .daily(startDate: Date(), endDate: Calendar.current.date(byAdding: .day, value: 1, to: Date())!)).first.debugDescription                 }             } label: {                 Text("Get the test weather")             }             Text(localWeather) When I'm using this exact code on a real device I get the following 404 error: [WeatherDataService] Received invalid http response code 404 for request: C7AEC7CC-E5F7-425D-8491-25B9302E2A0F:0 [WeatherService] Encountered an error when fetching weather data subset; location=<+52.51530000,+6.08565000> +/- 0.00m (speed -1.00 mps / course -1.00) @ 05/01/2023, 13:55:53 Central European Standard Time,  error=responseFailed(<NSHTTPURLResponse: 0x282ce0260> { URL: https://weather-data.apple.com/v3/weather/en/52.515/6.086?timezone=Europe/Amsterdam&dataSets=forecastHourly,forecastDaily&dailyStart=2023-01-10T12:00:00Z&dailyEnd=2023-01-10T12:00:00Z&hourlyStart=2023-01-10T11:00:00Z&hourlyEnd=2023-01-10T16:00:00Z&country=NL } { Status Code: 404, Headers {     "Access-Control-Allow-Origin" =     (         "*"     );     "Cache-Control" =     (         "max-age=0, no-cache, no-store"     );     Connection =     (         "keep-alive"     );     "Content-Length" =     (         0     );     "Content-Security-Policy" =     (         "default-src 'self';"     );     Date =     (         "Thu, 05 Jan 2023 12:59:27 GMT"     );     Expires =     (         "Thu, 05 Jan 2023 12:59:27 GMT"     );     Pragma =     (         "no-cache"     );     Server =     (         "AppleHttpServer/21be5247c6351682d1d9aa22fe98c8f0d4902838"     );     "Strict-Transport-Security" =     (         "max-age=31536000; includeSubDomains",         "max-age=31536000"     );     "X-Apple-Origin" =     (         "bcd49c7f-c567-3921-a041-3d4ef58e5423"     );     "X-B3-TraceId" =     (         c8c6547722afc53f     );     "X-Cache" =     (         "TCP_MISS from a104-110-190-91.deploy.akamaitechnologies.com (AkamaiGHost/10.10.3-45298580) (-)"     );     "X-Content-Type-Options" =     (         nosniff     );     "X-Frame-Options" =     (         DENY     );     "X-REQUEST-ID" =     (         "407e37bc-ddf6-45fd-84d0-1d3d3b8651b0"     );     "X-XSS-Protection" =     (         "1; mode=block"     ); } }, Optional("")) I fixed it once by deleting Xcode and the app from my iPhone, but that doesn't work anymore. Any suggestions?

Hello. I took a closer look at the data I'm getting back for hourly forecasts and I'm baffled by results I'm seeing. For example, it's Dec 19, 2022 8:00am PT and I'm asking for the weather for Orchard Park NY (lat 42.766437 long -78.743855) for Dec 23, 2022. The daily forecast tells me they're expected to have 5.9" of snow. However, the hourly forecast with the most snow that day is reported as 0.071" (1.8mm). The Apple Weather app on iOS shows that hour as having 0.6". I wrote a 'for' loop to print the results of my call to WeatherService.shared.weather.         print(oneHour.precipitationAmount.formatted())         print(oneHour.precipitationAmount.description)         print(oneHour.precipitationAmount.unit)         print(oneHour.precipitationAmount.value) 0.071 in 1.8 mm <_NSStatic_NSUnitLength: 0x2010b0178> mm 1.8

I am able to obtain daily forecasts via the REST API which include the daytimeForecast and overnightForecast records with their respective properties like cloudCover. So far I have failed to access them via the Swift API: forecast.daytimeForecast.cloudCover results in: "Value of type 'DayWeather' has no member 'daytimeForecast'". But if I print() the DayWeather objects, these members are actually printed with all their properties. Is there a way to get them I am overlooking?

Until recently, I was unable to use WeatherKit to obtain historical Daily data. Now, it appears that I can retrieve Daily and Hourly historical data, but the returned data is limited to a ten day period. No matter what start and end dates are included, I get data from start date to 10 days later (assuming the end date was more than 10 days after the start). Is this a permanent restriction? Example: let historicalData = try await weatherService.weather(for: location, including: .daily(startDate: startDate, endDate: endDate))
