Is there any information on what the AudioPlaybackIntent does? The documentation doesn't give any information on it: https://developer.apple.com/documentation/appintents/audioplaybackintent I have an audio app and I want to add a play/pause button to our widget for iOS17, I'm assuming I need to use an AudioPlaybackIntent but there is no documentation on what it does. Thanks.

Is it possible to tell in your code if the app was launched from an app intent action in a widget. In my SwiftUI code it has something like Button(intent: MyIntent()) I want to be able to tell when the user has clicked on the button to launch the app, because I need some different setup code to run before the intent perform method is called. Thanks

The docs for this property say: "Apps that play long-form audio, such as music or audio books, can use this policy to play to the same output as the built-in Music and Podcast apps. Long-form audio apps should also use the Media Player framework to add support for remote control events and to provide Now Playing information." That doesn't really say what the benefit is for adding this option or what are the drawbacks? Does somebody have some more information on when you should use this policy and potential issues it might cause? We are working on a music app that will play music in the background so it sounds like we should add this policy, but I can't find any information about why you should. Thanks

Is it possible to retrieve the sleep schedule wakeup and bedtime times using HealthKit? I can retrieve sleep analysis values, but I don't want the detailed data just the wake up and bedtime times the user has possibly specified in the health app, I can't see any way to retrieve those values. Thanks.

I am using AVAudioEngine, I have a stereo wav file that I want to use with an AVAudioEnvironmentNode but it requires the input source is mono otherwise it will not spatialize the sounds. Is there some way I can convert the stereo input to mono dynamically, maybe using an avaudiomixernode or something else? It looks like maybe I can use AVAudioConverter to convert the original buffer, but I want to be able to just add a node in the AVAudioEngine graph that can convert it to mono if that is possible, rather than having to convert the input buffer explicitly. So something like: WAV -> AVAudioPlayerNode -> Stereo to mono node -> AVAudioEnvironmentNode

I'm seeing a decent number of crash reports from our app where SceneKit is crashing internally relating to SCNPhysicsField. The stack looks like: objc_msgSend -[SCNPhysicsField _removeOwner] -[SCNNode dealloc] AutoreleasePoolPage::releaseUntil(objc_object**) -[UIApplication _run] UIApplicationMain main start It must be that I am removing a node that has a physics field on it and it randomly crashes. Probably threading related? Anyone know if there is a workaround, maybe setting physicsField to nil first before trying to remove the node? Thanks

How do you change the monthly plan? I don't see anywhere in the developer accounts pages to do it or in app store connect. The only things I see in developer accounts is a services list with a weatherkit item, but it just shows usage numbers, no option to upgrade to a different plan.

If you exceed the monthly quota in your WeatherKit plan what happens when you make an API call (Swift SDK), does it just error out? Will Apple give you some grace period to upgrade your quota to a larger value before stopping you from being able to make queries?

Does WeatherKit work for users in China? Some of our APIs to fetch weather data from other sources have been blocked in China, we are hoping WeatherKit will work as a replacement for them (we are using the Swift APIs to integrate with WeatherKit). Hopefully calling WeatherKit using the Swift APIs inside China from an iOS device will return data successfully and not fail. Thanks.

Why does the documentation say this field returns the intensity of precipitation in UnitSpeed, this seems confusing. Shouldn't the amount of precipitation be an amount like inch/hr, mm/hr why would the value be in speed? The old dark sky documentation for this field shows the units were returned in inches/hour

If you use the iOS16 Swift WeatherKit API you can get the weather data attribution logo doing something like: // Skipping full syntax for example let attribution = WeatherService.shared.attribution // A URL to an image you can show along with the weather data attribution.combinedMarkLightURL What about if you are not using the iOS16 WeatherKit wrappers e.g. you are using the REST API on your own server to return data. The API docs show a providerLogo/providerName parameter in the metadata returned from the service, but they don't seem to be populated right now. Is it ok just to use a unicode Apple logo to make a string instead like:  Weather Also in the API there is a metadata object returned in each dataset e.g. current, daily, hourly which each has an attributionURL field, will all those values always be the same or we might have to display multiple URLs for data sources, the Swift example seems to just have one attribution object.

The documentation lists the number of calls per month you can make for the different pricing tiers here: https://developer.apple.com/weatherkit/get-started/ but are there going to be any per second/minute/hour rate limits on calls to the API like with other weather service APIs. For example maybe you get 1,000,000 calls per month but there is some limit like 5 calls per second or 10,000 calls per hour imposed by the APIs? Also what happens if you go over your allowed call limit for the month, will the API just return an error like HTTP 402 or you will get a warning for a period of time? Would you be able to buy extra calls for the month without having to upgrade to a new tier, assuming maybe you are experiencing a temporary increase in traffic.

Hi - I don't see anything in the documentation about which regions of the world the API will support e.g. US, Europe. I see there is an /api/v1/availability you can call but is there some rough guidelines around what areas are supported and which aren't. Thanks Mark.

I'm not sure which combination of iOS/XCode/Mac OS is causing this issue, but all of a sudden when I try to run our SceneKit app and the "Scheme -> Diagnostics -> Metal -> API Validation" setting is turned off the scene won't render and the console is just full of the following errors: Execution of the command buffer was aborted due to an error during execution. Invalid Resource (00000009:kIOGPUCommandBufferCallbackErrorInvalidResource) [SceneKit] Error: Main command buffer execution failed with status 5, error: Error Domain=MTLCommandBufferErrorDomain Code=9 "Invalid Resource (00000009:kIOGPUCommandBufferCallbackErrorInvalidResource)"  ) If you run the app outside of xcode it's fine, also enabling the "API Validation" option stops the issue. One of my schemes has this option disabled since the project began and never had an issue before. Just throwing this out there incase someone else has spent hours of their life trying to figure out why this is not working for them. Also you can just create a new SceneKit project and turn that diagnostic option off and the app won't render anything.

Hi - I have an auto-renew subscription, for some reason when the user looks at their subscriptions in the iOS subscription list the subscription shows the productId as the name e.g. com.company.app.subscriptonName not the localized string e.g. "Foo Monthly Subscription". I have other subscriptions and they all works as expected and show the localized name. The one that is showing the productId is configured the same as the others as far as I can tell, any reason why this is happening and how to fix it? Thanks.
