SwiftUI List performance

Hello everyone, I am currently developing an app for my Swift Student Challenge submission that focuses on human motion analysis using the Vision framework. To effectively demonstrate the app's technical capabilities during the review process, I need to include a sample video showing a person performing specific movements. However, I want to ensure that my submission strictly adheres to all intellectual property guidelines. Instead of using existing copyrighted videos or public social media clips, I am considering using Generative AI to create an original, royalty-free sample video. This video would feature a character performing movements designed specifically to test my app's pose estimation and feedback logic. I have a few questions regarding this approach: Is it acceptable to use AI-generated sample assets (like video clips) to demonstrate technical features when it's difficult to record high-quality personal footage due to environmental constraints? If I clearly disclose the tools used

This extension View { public func renderSomething() async throws { let renderer = ImageRenderer(content: self) // renderer.colorMode = .linear renderer.render { size, context in print(size) // ... } // ... } } let view: some View = ... view.renderSomething() // → exception will cause the program to exit with EXC_BREAKPOINT deep inside SwiftUI. This worked with previous versions of Xcode, SwiftUI, and macOS. Xcode Version 26.2 (17C52), macOS Sequoia 15.7.3, using toolchain bundled with Xcode.

I am using swift-subprocess, and need to disable the SubprocessSpan trait because Xcode 26.2 does not ship with a bundled version libswiftCompatibilitySpan.dylib, causing everything to crash built with Xcode that happens to use Span. However, I cannot disable that trait by doing any of the following things: .package( url: https://github.com/swiftlang/swift-subprocess.git, branch: main, traits: [] ), .package( url: https://github.com/swiftlang/swift-subprocess.git, branch: main, traits: [.trait(name: SubprocessFoundation)] ), Note that SubprocessSpan is default trait in subprocess: // Enable SubprocessFoundation by default var defaultTraits: Set = [SubprocessFoundation] #if compiler(>=6.2) // Enable SubprocessSpan when Span is available [except it is not] defaultTraits.insert(SubprocessSpan) #endif The package still builds with the SubprocessSpan enabled. This is not an issue with the subprocess package. According to this, I should use swift build on the command line, yet this isn't -- as is upgrading to Ta

Hardware Specifications Regarding the LiDAR scanner in the iPhone 13/14/15/16/17 Pro series, could you please provide the following technical details for academic verification: Point Cloud Density / Resolution: The effective resolution of the depth map. Sampling Frequency: The sensor's refresh rate. Accuracy Metrics: Official tolerance levels regarding depth accuracy relative to distance (specifically within 0.5m – 2m range). Data Acquisition Methodology For a scientific thesis requiring high data integrity: Does Apple recommend a custom ARKit implementation over third-party applications (e.g., Polycam) to access raw depth data? I need to confirm if third-party apps typically apply smoothing or post-processing that would obscure the sensor's native performance, which must be avoided for my error analysis.

Hello, I have a question regarding the lifecycle of user consent and tokens in Sign in with Apple. Specifically, I would like to understand the behavior of the auth/revoke API in relation to App Store Connect status changes. Impact of App Status Changes If an app is Removed from Sale or Deleted from App Store Connect, does Apple automatically revoke all associated user tokens and consent? Or is it still the developer's responsibility to programmatically revoke each user's token via the REST API to ensure the app is removed from the user’s Apps Using Apple ID list? API Availability after Removal Once an app is no longer available on the App Store (or its record is deleted in App Store Connect), is the auth/revoke REST API still accessible? I want to ensure that a developer can still perform necessary privacy clean-up tasks (revoking consent) even if the app is not currently distributed. Specific User Impacts of Non-Revocation If we do not call the revocation API, besides the app remaining in

I am profiling a simple SwiftUI test app on my new iPhone through my new MacBook Pro and everything is version 26.2 (iOS, macOS, Xcode). I run Instruments with the SwiftUI template using all of the default settings and get absolutely zero data after interacting with the app for about 20 seconds. Using the Time Profiler template yields trace data. Trying the SwiftUI template again with the sample Landmarks app has the same issue as my app.

I've developed a Multiplatform app under Xcode 26 (currently using 26.2 17C52). The current destinations of the single target are Mac, iPad and Mac(designed for iPad). The minimum deployments are MacOS 15.6 and iOS 18.6. All destinations build and perform correctly on physical devices (running OS 26 versions). The MacOS version has been submitted successfully to the AppStore for TestFlight usage. However, the iPad version shows a submission validation failure: Missing Info.plist value. A value for the key “WKApplication”, or “WKWatchKitApp” if your project has a WatchKit App Extension target, is required in “xxxxx.app/xxxxx.app” bundle. For details, see: https://developer.apple.com/documentation/watchkit/creating_independent_watchos_apps/setting_up_a_watchos_project (ID: 4911506c-39c3-4b69-a8bb-5e5dcd3dc2fb) The app has no WatchKit version (although one's planned for a future release). The Target's Build Settings include a watchOS Deployment Target and Info.plist values related to WatchKit. The Build

Hi, I'm running into a weird notarization issue and wanted to see if anyone else has seen something similar. I have one main macOS app that keeps doing the following: The notarization sits in In Progress for a few days Then it flips to Rejected with error code 7000 The notarytool log shows no issues and no ticket info At the same time, smaller test apps on the same Apple Developer account notarize. They do take around 2-3 days though. So it doesn't seem like an account or certificate problem. It looks like something about this specific app causes it to go into a long review and then fail with that vague 7000 error. The app is fairly large (Python + Qt, lots of bundled libraries), so I'm wondering if that triggers deeper scanning or some kind of policy check. Has anyone else seen: Multi day notarization jobs? Error 7000 that only affects one particular app? Rejections with no issues listed? If so, did you find a way around it? Also for context, my Apple Developer account was created recently I have co

I have a new app I am working on, it uses, a container id like com.me.mycompany.FancyApp.prod, the description in the app is My Fancy App. When I deploy the app via TestFlight on a real device, the sync seems to work, but when I view iCloud->Storage-List, I see my app icon, and the name prod. Where did the name prod come from? It should be My Fancy App, which is the actual name of the App.
