I'm trying to get historical data using the following syntax: try await service.weather(for: location, including: .daily(startDate: past1, endDate: past2)) Where past1 and past2 are two dates in the past (I checked their format and they are correct). I always get the same result, namely the 10 days default forecast you usually get calling service.weather(for: location) Am I missing something?

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?

Hi, I'm in the process of developing a weather app using WeatherKit. Everything seems to be working fine in the Simulator, but when I put it on the device (iPhone 13 Pro Max) the temperature displays wrong. Example: On Simulator: 34 F On Device: 34.98 F Anyone else have this problem? Dan Uff

'async' call cannot occur in a global variable initializer for weather variable. import WeatherKit import CoreLocation let weatherService = WeatherService() let chicago = CLLocation(latitude: 47, longitude: 87.58293) let weather = try! await weatherService.weather(for: chicago) let temperature = weather.currentWeather.temperature

How is the IsDaylight value derived, and what factors are typically considered in its calculation? Specifically, is it determined based on the sunrise and sunset times, or are other factors considered? If it is based on sunrise and sunset times, is it based on Astronomical, Civil, and Nautical values? Are Weather and altitude considered as well? Thank you,

After Apple essentially shut down Dark Sky early (you can't trust it if it's off-line 8 hours a day 2/3 days), I've transitioned production traffic to WeatherKit. Generally slower (higher p50's, significantly higher p90s) Under bursts of traffic, it just chokes. Always. I have many users who have things set up to retrieve the weather on the hour (e.g., 6:00am). I have to have a failover weather source for these peaks, because weather kits just stops returning data under heavy load. It's not really acceptable that I'm paying significant $$$ for an API, and have to have another source for when the API predictably chokes. Dark Sky handled the load without breaking a sweat. Ever. I'm not sure what to do here. It's not an issue with the code, so there's no point in opening a code level support ticket. The feedback assistant refers you to the forums. General performance issues are not addressed by Apple engineers on the forums. So, the whole thing is a bit Kafkaesque. Is stumbling under load expected behavior? Does Apple have any performance expectations for the API? I've never dealt with an API provider that you couldn't get some sort of acknowledgement about issues. It's just weird.

Since September 8th, I've been unable to access the WeatherKit REST API due to authentication errors -- no changes on my side, but now I'm always getting responses like the following from the API: "status": 403, "error": "Forbidden", "message": "Access Denied", Has anyone else run into this problem in the last few days, and/or know how to work around it? The only place I've seen other report reporting so far is here: https://twitter.com/keff85/status/1569054904655773696 I tried upgrading to a paid WeatherKit plan (the lowest level is $50/month) but that doesn't seem to have helped. I believe WeatherKit Swift is working fine, but WeatherKit REST seems to be down -- or perhaps the auth changed somehow without warning?

Hi there! Please could you publish some of the specifics for authentication for the new WeatherKit REST API? I am attempting to use something cobbled together from MapKit, and unfortunately WeatherKit returns a 500 error in response. Broken code sample below. If you find a working solution or can identify an error, please comment with the solution. Thank you! require 'http' require 'jwt' require 'openssl' require 'logger' p8 = OpenSSL::PKey::EC.new(File.read("/PATH/TO/DOWNLOADED/P8/FILE")) token = JWT.encode({ iss: 'KEY_NAME_FROM_CIP', iat: Time.now.to_i, exp: Time.now.to_i + 3600, aud: 'weatherkit', }, p8, 'ES256', { kid: 'KEY_ID_FROM_CIP', typ: 'JWT' }) res = HTTP.use(logging: { logger: Logger.new(STDOUT) }).headers( "Authorization" => "Bearer #{token}" ).get "https://weatherkit.apple.com/api/v1/weather/en/LONG/LAT?dataSets=currentWeather&timezone=Europe/London" puts "code: #{res.code}" puts res.body

I am looking into the possibility of adding WeatherKit support to one of my apps. I have added the WeatherKit capability to my app and can see it up in the App ID configuration, the bundle ID is marked as explicit. I waited overnight just in case, but I keep just getting the following error when I run on a real device: Error Domain=WeatherDaemon.WDSJWTAuthenticatorService.Errors Code=1 "(null)" This app has been in the store for years, so I know the rest of the configuration should be fine. What am I missing?

I have an app that submits a rest-api request to weatherkit for both currentWeather and weahtherForecast data. The app will error from time to time because of unauthorized request but what I don't understand is that it does not happen 100% of the time. Anyone encountered something similar?

Insights & assistance would be greatly appreciated. Have a paid/current developers account which shows WeatherKit as being available/having 500,000 calls available, but I have not sorted out settings for ‘certificates, identifiers, and profiles’. Am attempting to use an iPad Pro with iOS 16 to run the following script using Swift Playgrounds Xcode Playground import WeatherKit import CoreLocation let weatherService = WeatherService() let Anchorage = CLLocation(latitude: 61, longitude: -149) let weather = try! await weatherService.weather(for: Anchorage) let temperature = weather.currentWeather.temperature print(temperature)  The error that I am seeing is: There was a problem running this playground. Please check your code and try again. There is no ‘red dot’ and technical guidance associated with resolving this error as one normally sees/experiences when working on scripts. Have exited/restarted Swift Playgrounds multiple times and still see this error. This error is unexpected, as I am usually able to create and run swift scripts on my iPad.

Hey everyone, I am working on a weather app using weatherKit on SwiftUI and I have everything set up such as the current weather, ten-day and hourly forecast. My only question is that I want to have the feature to search for a city that I want to add and see the weather information for a specific Country/city. How do I add an autocomplete search field. Is it possible to do it using weatherKit? Or its something completely different thing that I need to add. Thank you.

I've been unable to get MinuteWeather to return anything for the summary property -- it used to return a nil value which was fixed in a previous beta, but now it always returns an empty string. The rest of the MinuteWeather data returns as expected. Example call: let latitude = 37.323 let longitude = -122.032 Task { let weatherData = WeatherData.shared     let minutely = await weatherData.minutelyForecast(for: CLLocation(latitude: latitude, longitude: longitude))          guard let minutelyWeather = minutely else {       print("WeatherKit minutely data unavailable")       return }     print(minutelyWeather.summary) // This returns "" } WeatherData class: class WeatherData: NSObject { static let shared = WeatherData() private let service = WeatherService.shared func minutelyForecast(for location: CLLocation) async -> WeatherKit.Forecast<MinuteWeather>? { let minuteWeather = await Task.detached(priority: .userInitiated) { let forecast = try? await self.service.weather(for: location, including: .minute) return forecast }.value return minuteWeather } }

try await WeatherService.shared.weather(for: sf, including: .daily(startDate: start, endDate: end)) If the start date is in the past I get an empty forecast. If start date is in the future I just get the current day's forecast. I tried with .hourly as well; got the same problem as I always get hourly data for the current day.

Hello, I'm quite new to SwiftUI Development, learned how to code without getting a Compute Science college Degree.

Hi, Will the Apple Weather framework work on Mac using SwiftUI? The documentation doesn't say MacOS. Thanks, Dan Uff

Hi all, I am trying to use the WeatherKit REST API but when I try to register an app, I don't see WeatherKit as an available services that I can select under the App Services Tab. How do I get access to the WeatherKit service? Thanks,

Has anyone else been able to retrieve weather data from MinuteWeather? Specifically, I'm looking to access summary, but MinuteWeather always returns nil and the WeatherAvailability check for it returns unsupported. I know it's not location based since I'm testing with the same locations I've used previously with the Dark Sky API (where minutely was available). Example call: let latitude = 37.323 let longitude = 122.032 Task { let weatherData = WeatherData.shared     let minutely = await weatherData.minutelyForecast(for: CLLocation(latitude: latitude, longitude: longitude))          guard let minutelyWeather = minutely else {       print("WeatherKit minutely data unavailable")       return }     // ... } WeatherData class: class WeatherData: NSObject { static let shared = WeatherData() private let service = WeatherService.shared func minutelyForecast(for location: CLLocation) async -> WeatherKit.Forecast<MinuteWeather>? { let minuteWeather = await Task.detached(priority: .userInitiated) { let forecast = try? await self.service.weather(for: location, including: .minute) return forecast }.value return minuteWeather } }

I'm working on an app with WeatherKit. The app works on the simulator, but it doesn't work on the real device. Calling "weatherService.weather(for: ..." never returns data or an error. do { let weather = try await weatherService.weather(for: myPlace) print(weather) // always on the simulator, never on the device     } catch { // never gets a call    print(error) } I'm using the latest beta on my device. Apple's TestFlight sample app doesn't work on the device, but it works fine on the simulator. Does anyone's WeatherKit work on a real device?

I'm following along to the WWDC WeatherKit session, and I keep getting this 401 network error that causes my app to crash on a fatal error. I have already created the proper Bundle App ID with WeatherKit enabled, and added the WeatherKit capability.
