“missing package product”

Hi forum! I’m currently following a series of videos about SwiftData. In the WWDC23 Build an app with SwiftData video, it mentions that you can follow up with a demo project. However, I’m encountering an issue (at least in my case) where there’s no link on the entire page to download the project. I can download the video and other resources (even using the Developer’s App), but there’s no link for the project. Does anyone else face this issue? Is it possible that the project has been removed? I’m using my developer (single user) account, by the way. Any guidance would be greatly appreciated!

I am trying to figure out why my app is not receiving background deliveries from Healthkit. I have a successfully implemented HKObserverQuery which is being used to send data like step count to a server. I have a successful enableBackgroundDelivery (completes without errors). I have also checkmarked the HealthKit Background Delivery and Clinical Health Records options in my app's Signing and Capabilities configurations. I know the observer is functional because the health data gets sent to the server when the app is running. The problem is I haven't seen any evidence of the observer handler being triggered when the app is not running. What am I missing? And what is the best way to go about debugging what is going wrong?

Hi team, I am having an issue with paying for my apple developer enrolment program. Error message is: Your payment authorisation failed on card XXXX. Please verify your information and try again, or try another payment method. Things I have tried and has not worked: Multiple company visa card Multiple personal visa card Ensuring billing address matches my visa cards Turn off VPN Try my personal IOS device My company and personal cards should work because I have paid for other products and apple products with it. I do not think this is an isolated incident and that Apple should look into this immediately to prevent blocking developer enrolment.

I currently have a schema in production (cloudKit and local files) containing non-optional transformable values, e.g. @Attribute(.transformable(by: TestTransformer.self)) var number: TestTransformable = TestTransformable.init(value: 100) Unfortunately, this is preventing any migration from succeeding (documented at length in FB22151570). Briefly summarized, any migration from a Schema containing non-optional transformable values fails between willMigrate and didMigrate with the error Can't find model for source store. This occurs for all migrations, including lightweight with a migration plan, lightweight without a plan, and custom migrations. Worst of all, this also prevents migration to optional transformable values, or the elimination of the transformable value entirely, leaving us completely stuck. (note: optional transformable values only work when they have a default value set to nil, otherwise even these have issues migrating) We already have features being blocked by this issue, and would lik

In Swift, iOS, I have a pdf file. I want to take the pages 2 by 2 and put them side by side, on the new page. For this, I have to scale initial pages half size and rotate .pi/2. I managed to achieve this by converting pdf pages to UIImages and using a UIGraphicsImageRenderer. But with a critical loss of resolution. I've tried improving the resolution by creating images as jpegData(withCompressionQuality: 1.0), to no avail. So I would need to work directly on the pdf pages using CGPDFDocument format. The code structure is as follows, to insert a single scaled page: for iPage in … { if let _page = theCGPdfDocument.page(at: 1) { var _pageRect: CGRect = _page.getBoxRect(CGPDFBox.mediaBox) writeContextInDestination!.beginPage(mediaBox: &_pageRect) // translate to compensate for the flip caused displacement writeContextInDestination!.translateBy(x: _pageRect.size.width, y: _pageRect.size.height) Scale (-1, -1) // rotate 180° // add rotate as needed writeContextInDestination!.scaleBy(x: -1, y: -1) write

Hi Everyone, We are currently migrating a mature legacy KEXT to DriverKit for our PCIe SCSI storage controller (connected via Thunderbolt 3). During the DEXT load sequence, we have observed that the system automatically triggers a power state transition from State 0 (Off) to State 2 (On). However, this process results in a Kernel Panic due to a timeout after approximately 21 seconds. We have verified that our implementation of Start_Impl, UserInitializeController_Impl, and SetPowerState_Impl executes extremely fast, with a total execution time of less than one second. Specifically, SetPowerState_Impl returns kIOReturnSuccess immediately upon being called. Furthermore, our current Info.plist does not contain any IOPowerManagement dictionary or related keys. Despite the fast execution and the absence of explicit power management declarations in the plist, the kernel power management state machine (IOServicePM) still generates a 21-second timeout, leading to the following panic: Panic Log: panic(cpu 7 caller 0xf

Hello everyone, I’m an iOS developer working on a real-time communication app that supports VoIP calls using CallKit. The app has been in production for more than 5 years. Over the years, some users have occasionally reported that they do not receive incoming call pushes. We have tried multiple optimizations on both the client and server side, but the improvement has been limited. From Apple documentation and discussions online, I understand that iOS may restrict VoIP pushes if the system detects violations of VoIP push usage rules (for example, not presenting a CallKit call after receiving a VoIP push). However, the exact rules and thresholds for these violations are not clearly documented, so I’d like to ask a few questions to better understand the expected behavior. Below is a simplified description of our current call flow. Call Flow Caller When the user initiates a call: We do not use CallKit The call is handled entirely using a custom in-app call UI Callee When the user receives a call: Device

Apple has introduced the Wireless Insights Service Predictions capability in iOS 26. After prior alignment with Apple engineers, we are working to integrate this capability into the Douyin App, and intend to provide a TestFlight build for Apple engineers to validate and debug the integration. We have encountered a blocking issue with entitlement configuration: We use our Apple Developer Enterprise Program account to build and submit TestFlight builds. When we manually create and configure provisioning profiles via the Apple Developer Portal, the required entitlement key com.apple.developer.wireless-insights.service-predictions is not available for selection or inclusion in the profile's Entitlements. This completely blocks us from enabling, using, and validating the Wireless Insights Service Predictions capability. For comparison, when we use our Apple Developer Program individual account, the entitlement com.apple.developer.wireless-insights.service-predictions is fully available. It is automatically include
