Hello everyone, We are the developer of PhotoMagic – AI Photo Editor, and we would appreciate guidance from the community regarding a pending enforcement case currently under review by the App Review Board. Case Information Case Number: 102812414888 App ID: 6746860005 Notice Date: January 25, 2026 Current Status: Pending review by the App Review Board Reason cited: Section 3.2(f) of the Apple Developer Program License Agreement The notice stated that our app submissions were considered to have “repeatedly violated the App Review Guidelines in an attempt to evade the review process.” Background & Acknowledgement Upon receiving the notice, we immediately conducted a comprehensive internal audit. During this process, we identified that certain user-uploaded template content (for example, templates involving concepts such as “kiss” or “hug”) posed potential policy risks. We would like to clearly state that we did not intentionally hide or disguise content to evade App Review. However, we fully acknowledge tha

Hello, I’m seeking clarification on In-App Purchase requirements for a marketplace vendor app offering real-world, offline services. We plan to offer paid vendor listing plans (Free, Silver, Gold, etc.) that provide business benefits such as increased visibility, analytics, and also include feature limits like the number of images a vendor can upload to their business profile and enhanced dashboard views. These plans are intended to support vendors’ real-world businesses and do not provide digital content to consumers. Does gating vendor features such as image upload limits or dashboard capabilities require Apple In-App Purchase under App Store Review Guideline 3.1, or can such vendor plans be processed using a third-party payment gateway as account-based service tiers?

I'm struggling to understand whether TextField handles undo by itself, or how to properly handle it myself. In a macOS app with a SwiftUI lifecycle, in a DocumentGroup scene, I'm using both TextEditors and Textfields. The text editors handle undo out of the box, with undo coalescing. The text fields seem not to. However, on occasion, they do create undo points, leaving me confused as to what conditions are needed for that to happen. Is there a way to reliably get text fields to handle undo on their own? Or, how should I implement typing undo, including undo coalescing, manually?

Hello, I have implemented Low-Latency Frame Interpolation using the VTFrameProcessor framework, based on the sample code from https://developer.apple.com/kr/videos/play/wwdc2025/300. It is currently working well for both LIVE and VOD streams. However, I have a few questions regarding the lifecycle management and synchronization of this feature: 1. Common Questions (Applicable to both Frame Interpolation & Super Resolution) 1.1 Dynamic Toggling Do you recommend enabling/disabling these features dynamically during playback? Or is it better practice to configure them only during the initial setup/preparation phase? If dynamic toggling is supported, are there any recommended patterns for managing VTFrameProcessor session lifecycle (e.g., startSession / endSession timing)? 1.2 Synchronization Method I am currently using CADisplayLink to fetch frames from AVPlayerItemVideoOutput and perform processing. Is CADisplayLink the recommended approach for real-time frame acquisition with VTFrameProcessor? If t

I'm running Xcode 26.2 (17C52). After deleting all simulators and creating new ones, SwiftUI Preview stopped working. Xcode reports: “Simulator [D774B214-XXXX-XXXX-XXXX-XXXXXXXX8288] failed to boot and may have crashed.” However, when I list all available simulators using xcrun simctl list, there is no simulator with that identifier. It seems Xcode is still referencing a previously deleted simulator. I have tried: Deleting all simulators again Creating new simulators Restarting Xcode and the system But the issue persists and Preview still fails to launch. Has anyone encountered this issue or knows how to clear the cached simulator reference used by SwiftUI Preview?

I'm trying to replicate edit/select mode of iOS 26 photos app. When user clicks Select button, bottom tab bar is replaced by the toolbar buttons. When I press Done button, a white opaque bar appears at the bottom behind the tabbar. It looks pretty straightforward to implement but I'm banging my head here now. Any help will be appreciated. Code and animation frames attached bellow struct ContentView: View { var body: some View { TabView(selection: $selectedTab) { OverviewView() .tabItem { Image(systemName: chart.pie) Text(Overview) } .tag(0) //rest of the tabs } } } struct OverviewView: View { @State private var editActive = false @State private var selection = Set() @State private var items = [ Item 1, Item 2, Item 3, ] var body: some View { NavigationStack { List(selection: $selection) { ForEach(items, id: .self) { item in Text(item) } } .toolbar { if editActive { ToolbarItem(placement: .bottomBar) { Button { } label: { Label(Delete, systemImage: trash) } } ToolbarItem(placement: .bottomBar) { Butto

Some of our app's users are repeatedly running into a crash on NeutrinoCore -[NUIdentifier initWithNamespace:name:version:] + 2352. It looks from the stack trace like multiple threads are performing PHFetchRequests, but that shouldn't be causing a crash. It's isolated to a small number of users, which makes me think that it's something related to their specific Photos databases (e.g., data corruption.) Do you have any suggestions how I might be able to resolve this? 2 libsystem_c.dylib abort + 124 3 NeutrinoCore -[NUAssertionPolicyCrashReport notifyAssertion:] + 66 4 NeutrinoCore -[NUAssertionPolicyComposite notifyAssertion:] + 160 5 NeutrinoCore -[NUAssertionPolicyUnique notifyAssertion:] + 176 6 NeutrinoCore -[NUAssertionHandler handleFailureInFunction:file:lineNumber:currentlyExecutingJobName:description:arguments:] + 156 7 NeutrinoCore _NUAssertFailHandler + 176 8 NeutrinoCore -[NUIdentifier initWithNamespace:name:version:] + 2352 9 NeutrinoCore -[NUIdentifier initWithName:version:] + 84 10 Neutr
