I'm creating an app that uses WeatherKit to get weather data. I wanted to confirm if the requests made to the service during app development will be deducted from our monthly usage limit or credit? Thanks

Hello, I include a Privacy Manifest file in my app and specify one Privacy Nutrition Label Type (Email Address, for marketing purposes). My app uses some third-party SDKs like RevenueCat that contain Privacy Manifest files with nutrition label types specified (Purchases History for RevenueCat for example). Xcode can generate a report that aggregates all the data types that are collected by the app. But is App Store Connect updated when I upload a build? Or do I have to manually setup the App Privacy info? Thanks

Hello, I want to use Automatic Grammar Agreement to localise a string in my app, let say "three remaining activities". The string "three" is obtained by using a NumberFormatter with a numberStyle set to .spellOut (so I'm not using an Integer) var formatter: NumberFormatter = NumberFormatter() formatter.numberStyle = .spellOut let formattedCount: String = numberFormatter.string(from: count as NSNumber)! Text("key_with_string_\(formattedCount)") In my string catalog, I have translated the key key_with_string_%@ like this ^[%@ remaining activity](inflect: true), but it does not work. I've tried to add the integer value used by the number formatter in the key key_with_string_%@_%lld but it does not work. Should Automatic Grammar Agreement work normally just by using the formatted string provided by the NumberFormatter? If not, is there a way to specify to use a secondary variable (my count integer) to switch between different categories like one and other automatically? Thanks ! Axel

Hello, I'm trying to understand how dangerous it is to read and/or update model properties from a thread different than the one that instantiated the model. I know this is wrong when using Core Data and we should always use perform/performAndWait before manipulating an object but I haven't found any information about that for SwiftData. Question: is it safe to pass an object from one thread (like MainActor) to another thread (in a detached Task for example) and manipulate it, or should we re fetch the object using its persistentModelID as soon as we cross threads? When running the example app below with the -com.apple.CoreData.ConcurrencyDebug 1 argument passed at launch enabled, I don't get any Console warning when I tap on the "Update directly" button. I'm sure it would trigger a warning if I were using Core Data. Thanks in advance for explaining.

Hello, SwiftData is not working correctly with Swift Concurrency. And it’s sad after all this time. I personally found a regression. The attached code works perfectly fine on iOS 17.5 but doesn’t work correctly on iOS 18 or iOS 18.1. A model can be updated from the background (Task, Task.detached or ModelActor) and refreshes the UI, but as soon as the same item is updated from the View (fetched via a Query), the next background updates are not reflected anymore in the UI, the UI is not refreshed, the updates are not merged into the main. How to reproduce: Launch the app Tap the plus button in the navigation bar to create a new item Tap on the “Update from Task”, “Update from Detached Task”, “Update from ModelActor” many times Notice the time is updated Tap on the “Update from View” (once or many times) Notice the time is updated Tap again on “Update from Task”, “Update from Detached Task”, “Update from ModelActor” many times Notice that the time is not update anymore Am I doing something wrong? Or is this a bug in iOS 18/18.1? Many other posts talk about issues where updates from background thread are not merged into the main thread. I don’t know if they all are related but it would be nice to have 1/ bug fixed, meaning that if I update an item from a background, it’s reflected in the UI, and 2/ proper documentation on how to use SwiftData with Swift Concurrency (ModelActor). I don’t know if what I’m doing in my buttons is correct or not.

Hello, I'm planning to had an onboarding to one of my apps. I am thinking about a way for a user to not see the onboarding again if he installs the app on another device. So for example, the user completes the onboarding on its iPhone, then downloads the app on its iPad and launch it, he doesn't see the onboarding a second time. I thought about using iCloud NSUbiquitousKeyValueStored to store the onboarding completion state. But I'm not sure when the data is synced to the other device logged into the same Apple account: Immediately even if the app is not installed on the other device (independent from the app, only iCloud thing)? At the same time as the app install on the other device? After the app is first launched on the other device? Of course synchronisation will depend on the Internet connection, speed, etc. so the app should handle the case where the data is not here but what would be the best case scenario? Thank you, Axel

When using SwiftUI Previews in a Swift Packages, are PreviewProviders automatically removed from the package when archiving an app, as it is the case with a app, or not? If not, how to deal with that? I’m not sure we can use compiler directives like if DEBUG in packages, can we?

Hello, My app uses Core Location to request for Points Of Interest near the user. I used the different APIs provided by Apple: MKLocalPointsOfInterestRequest, MKLocalSearch.Request and MKLocalSearchCompleter. They do not provide the same results at all, whereas the configurations for the requests are very similar. The MKLocalPointsOfInterestRequest provides very few places (if any, sometimes The operation couldn’t be completed. (MKErrorDomain error 4.) The others give more results but not identical. The code for the different requests is provided below. Is this the expected behaviour? If no, have I missed something? Is this a bug? Thanks PS: Tested on Xcode 14.3, iOS 16.0. MKLocalPointsOfInterestRequest let center: CLLocationCoordinate2DMake = CLLocationCoordinate2DMake(41.38891, 9.16205) let poiRequest: MKLocalPointsOfInterestRequest = MKLocalPointsOfInterestRequest(center: coordinate, radius: 3_000) poiRequest.pointOfInterestFilter = MKPointOfInterestFilter(including: [.beach]) let poiSearch: MKLocalSearch = MKLocalSearch(request: poiRequest) let resultsPOI = try await poiSearch.start() print(resultsPOI.mapItems.compactMap(\.name)) This give me the following result: ["Plage de Stagnolu"] MKLocalSearch.Request let center: CLLocationCoordinate2DMake = CLLocationCoordinate2DMake(41.38891, 9.16205) let searchRequest: MKLocalSearch.Request = MKLocalSearch.Request() searchRequest.region = MKCoordinateRegion(center: coordinate, latitudinalMeters: 4_000, longitudinalMeters: 4_000) searchRequest.pointOfInterestFilter = MKPointOfInterestFilter(including: [.beach]) searchRequest.resultTypes = .pointOfInterest searchRequest.naturalLanguageQuery = "beach" let search: MKLocalSearch = MKLocalSearch(request: searchRequest) let results = try? await search.start() print(results.mapItems.compactMap(\.name)) This give me se following results.

I want to animate part of my View when a property on a Core Data object is updated. These Core Data objects are ObservableObject so when I update a property on the object using a binding (like a Toggle) or a Button, I expect it to animate. But it’s not working. If I toggle a boolean property on my object, there is no animation. If I change a Boolean value in a Button using a withAnimation block, it does not animated. If I do the same with an ObservableObject class (boolean is a Published property), the animation is respected. A workaround is to use another property (isFavoriteWrapped) and to call objectWillChange.send() manually in the property setter. But this feels wrong. The expected behaviour should be similar to what we see with the ObservableObject. I opened a FB12174214.

See attached screenshots. How can this design be reproduced in SwiftUI? The capsules are positioned to represent the values. But the calculation needs to take into account the labels width. I tried using a mix of Grid and custom Layout but I haven’t found a way… Any help would be appreciated! Thanks

Hello, I'm currently developing an app using SwiftData. I want the app to use CloudKit to sync data, so I made sure all my model properties are optional. I've defined a Codable enum as follows: enum Size: Int, Codable { case small case medium case large } I've defined a Drink SwiftData model as follows: @Model class Drink { var name: String? var size: Size? init( name: String? = nil, size: Size? = nil ) { self.name = name self.size = size } } In one of my Views, I want to use a @Query to fetch the data, and use a Predicate to filter the data. The Predicate uses the size enumeration of the Drink model. Here is the code: struct DrinksView: View { @Query var drinks: [Drink] init() { let smallRawValue: Int = Size.small.rawValue let filter: Predicate<Drink> = #Predicate<Drink> { drink in if let size: Size = drink.size { return size.rawValue == smallRawValue } else { return false } } _drinks = Query(filter: filter) } var body: some View { List { ForEach(drinks) { drink in Text(drink.name ?? "Unknown Drink") } } } } The code compiles, but when I run the app, it crashes with the following error: Thread 1: Fatal error: Couldn't find \Drink.size!.rawValue on Drink with fields [SwiftData.Schema.PropertyMetadata(name: "name", keypath: \Drink.name, defaultValue: nil, metadata: nil), SwiftData.Schema.PropertyMetadata(name: "size", keypath: \Drink.size, defaultValue: nil, metadata: nil)] How can I filter my data using this optional variable on the Drink model? Thanks, Axel

Hello, I'm trying to create a subscription for one of my apps. When I specify the Product ID yearly_3, I get the following error message: The Product ID you entered is already being used by another subscription. This app does not have any other subscriptions with this Product ID. But I have another app with a yearly_3 Product ID. According to the official documentation, the Product ID is A unique ID specific to your app. So I thought it was possible to have the same Product ID between apps, but not for the same app. What's the rule here? Thanks, Axel

Hello, I've noticed the prices of my products in my Xcode synced StoreKit configuration are not updated when I change the price in App Store Connect. I tried to manually sync the file, to remove and add it again to my project but old initial prices are still used. In the screenshot below, the price is currently $2.99 but the file still uses the initial price of $1.99. It makes testing a little bit painful because I'm never sure which product is being shown. Is this a bug? Is there a way to get the live production App Store prices be used instead of the starting prices? I filed a feedback for this: FB17798486 Regards, Axel
