Does UNNotificationRequest have a 64-notification scheduling limit?
Hi, We have a simple calendar reminder app that uses UNNotificationRequest to schedule local notifications for user events. I’m wondering whether UNNotificationRequest has a system-imposed limit of 64 upcoming scheduled notifications, similar to the deprecated UILocalNotification. We’re asking because one of our users is not receiving recently scheduled reminders. Our current workflow is: We schedule notifications on app launch and when the app is about to quit. Before scheduling, we call removeAllPendingNotificationRequests(). We then fetch the 64 nearest upcoming events and schedule them using UNUserNotificationCenter.current().add(...). This approach works fine during our testing, but we’re unsure what might be causing the issue for some users. Any insights would be appreciated. Thanks!

UIToolbar buttons losing spacing in Xcode 26.1.1 Legacy Mode (UIDesignRequiresCompatibility)
We're using XCode 26.1.1 We do not have resource to adopt Liquid Glass design. Hence, we are using the following workaround <key>UIDesignRequiresCompatibility</key> <true/> This is our Storyboard. Pre XCode 26 Before XCode 26.1.1, the bottom toolbar looks great. In XCode 26 However, in XCode 26.1.1, the bottom toolbar buttons seems to "Squish together". Do anyone have any idea, how I can make UIToolbar works by enabling UIDesignRequiresCompatibility? Thanks.

Managing Legacy Subscriptions on the App Store
I have several subscription plans in the App Store that I no longer wish to offer to new users. In my app, these old subscriptions are hidden, but they remain active so existing subscribers can continue their plans and be charged as usual. However, some new users are still able to switch to these old subscription plans through the App Store. What is the best solution for this situation? I want to continue serving existing subscribers while preventing new users from subscribing to these legacy plans. Thank you.

Unexpected Change in Apple Refund Handling CONSUMPTION_REQUEST - Impact on Subscription App with AI Backend
We offer a 3-day free trial, and our paywall clearly states that users will be charged after the trial ends. However, some users request refunds after the charge - even after fully using our app for days or even weeks. In some cases, refunds are approved despite the users having consumed our AI processing services for up to a month. Since our app relies on backend AI processing, each user session incurs a real cost. To prevent losses, we utilize RevenueCat’s CONSUMPTION_REQUEST system and have set our refundPreference to: "2. You prefer that Apple declines the refund". Until recently, Apple typically respected this preference, and 90% of refund requests were declined as intended. However, starting about a week ago, we observed a sudden reversal: Apple is now approving around 90% of refund requests, despite our refund preference. As a result, we are operating at a loss and have had to halt both our marketing campaigns and our 3-day free trial. We’re trying to understand whether this shift is due to a change in Apple’s refund policy, or if we need to handle CONSUMPTION_REQUEST differently on our end. Has anyone else experienced similar changes? Any insights would be greatly appreciated.

How to Simulate Subscription Cancellation with Products.storekit in Simulator?
Hi, Currently, instead of using a real device and test account for in-app purchase testing, we are using Products.storekit with the Simulator. Our app offers a subscription plan with a 3-day free trial. We would like to simulate the following test scenarios: User cancels the subscription within the 3-day free trial period. User cancels the subscription after the 3-day free trial period. However, in Xcode, under Debug > StoreKit > Manage Transactions..., we couldn’t find an option to simulate a subscription cancellation. There is an option to refund the purchase, but we believe this is not the same as a cancellation. Do you have any idea how we can simulate these two cases using Products.storekit and the Simulator? Thanks in advance!

UIKit or SwiftUI First? Exploring the Best Hybrid Approach
UIKit and SwiftUI each have their own strengths and weaknesses: UIKit: More performant (e.g., UICollectionView). SwiftUI: Easier to create shiny UI and animations. My usual approach is to base my project on UIKit and use UIHostingController whenever I need to showcase visually rich UI or animations (such as in an onboarding presentation). So far, this approach has worked well for me—it keeps the project clean while solving performance concerns effectively. However, I was wondering: Has anyone tried the opposite approach? Creating a project primarily in SwiftUI, then embedding UIKit when performance is critical. If so, what has your experience been like? Would you recommend this approach? I'm considering this for my next project but am unsure how well it would work in practice.

Official document for CONSUMPTION_REQUEST - What kind of data we are receiving?
This documentation describes what kind of data we should be sending to Apple server, once we are receiving CONSUMPTION_REQUEST https://developer.apple.com/documentation/appstoreserverapi/consumptionrequest But, it doesn't describe what kind of data we are receiving, when we are receiving CONSUMPTION_REQUEST? May I know, is such a document available? Thank you.

Resolving 2nd Repeated "Guideline 4.3(a) - Design - Spam" Rejection Within Six Months
We are reaching out for guidance after encountering 2nd repeated "Guideline 4.3(a) - Design - Spam" rejections for our WeNote app. Here’s a brief timeline of our journey: 2018: We launched the WeNote Android app on Google Play Store. 2019: We started promoting WeNote on YouTube and began development of the WeNote iOS app. Our progress was publicly visible on our Trello board and discussed on the Apple Developer forum. August 17, 2021: We filed an official complaint with Apple regarding a *** company infringing on our app logo, title, and description. The issue was resolved when *** agreed to update their app’s branding. 2022 Year: *** company is terminated from App Store. June 2022: WeNote for iOS was officially released on the Apple App Store. June 17, 2024: We received a rejection from the Apple Review team citing Guideline 4.3(a) - Design - Spam: “We noticed your app shares a similar binary, metadata, and/or concept as apps previously submitted by a terminated Apple Developer Program account. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps.” We successfully resolved this issue by providing documentation about the previous incident on August 17, 2021. November 22, 2024: Unfortunately, we received the same rejection message again, despite having already informed Apple of the previous case. Request for Assistance: We are now seeking guidance from the community or anyone with experience in navigating similar issues. We’ve provided Apple with all the necessary evidence and explanations regarding the previous incident, but our appeal was rejected. How can we resolve this issue, and prevent future rejections? Some Background on WeNote: To help provide context, I’d like to highlight what makes WeNote stand out compared to other apps in the same category: WeNote is an all-in-one solution: While most apps in the market focus on one function—whether it’s note-taking, to-do lists, or calendar management—WeNote uniquely combines all three into a single app. This integration offers users a seamless experience to manage tasks, notes, and schedules in one place. Proven user satisfaction: We are proud to have over 7,000 user reviews, with an average rating of 4.8 stars. This high rating reflects our users' satisfaction with the app’s features and functionality, as well as its ability to meet their needs in a way that other apps do not. We believe these features make WeNote a valuable and unique tool for users, and we continue to prioritize quality and user experience in our development.

How to animate substring in a Text?
Currently, I am using multiple Texts in a horizontal stackview, to achieve animation of substring. As you can see in the above animation, the text - conversation - meeting - lecture are animated. However, there shortcoming of such an approach. Text size is not consistent among different Text block. The following Text block are having different text size. - Transform - conversation/ meeting/ lecture - to Quick Note Any idea how we can achieve, so that all text blocks have same text size so that they appear like 1 sentence? Or, how we can make the text blocks having constant text size, but able to perform line wrapping to next line, so that they appear like 1 sentence? Currently, this is the code snippet I am using. import SwiftUI struct ContentView: View { var array = ["lecture", "conversation", "meeting"] @State var currentIndex : Int = 0 @State var firstString : String = "" var body: some View { VStack { HStack { Text("Transform") .lineLimit(1) .minimumScaleFactor(0.5) .font(.title) Text(firstString) .lineLimit(1) .minimumScaleFactor(0.5) .font(.title) .transition(AnyTransition.opacity.animation(.easeInOut(duration:1.0))) .background(.yellow) Text("to Quick Note") .lineLimit(1) .minimumScaleFactor(0.5) .font(.title) }.padding() } .animation(.default) .onAppear { firstString = array[0] let timer = Timer.scheduledTimer(withTimeInterval: 2.0, repeats: true) { _ in if currentIndex == array.count - 1 { self.firstString = array[0] currentIndex = 0 } else { self.firstString = array[currentIndex+1] currentIndex += 1 } } } } } #Preview { ContentView() }

Troubleshooting Core Data Lightweight Migration: A Real-World Challenge
In my recent endeavor, I aimed to introduce new Fetch Index Elements to the Core Data model of my iOS application. To achieve this, I followed a process of lightweight migration, detailed as follows: Navigate to Editor > Add Model Version to create a new version of the data model. Name the new version with a sequential identifier (e.g., MyAppModelV3.xcdatamodel) based on the naming convention of previous models. Select the newly created version, MyAppModelV3.xcdatamodel, as the active model. Mark this new version as the "Current" model in the Xcode properties panel on the right. In the new version of the model, MyAppModelV3.xcdatamodel, and add the new Fetch Index Elements there. Also, insert "v3" in the Versioning Hash Modifier field of affected entity, to indicate this modification. Upon reflection, I realized that creating a new version of the xcdatamodel might not have been necessary for this particular case. However, it appears to have caused no adverse effects on the application's functionality. During testing, I executed the application in a simulated environment, initially running an older version of the app to inspect the database content with SQLite DB Browser. I then upgraded to the latest app version to verify that the migration was successfully completed without causing any crashes. Throughout this testing phase, I employed the -com.apple.CoreData.MigrationDebug 1 flag to monitor all SQL operations, ensuring that indexes were appropriately dropped and recreated for the affected entity. Following thorough testing, I deployed the update to production. The majority of users were able to upgrade to the new app version seamlessly. However, a small fraction reported crashes at startup, indicated by the following error message: Fatal error: Unresolved error Error Domain=NSCocoaErrorDomain Code=134110 "An error occurred during persistent store migration." UserInfo={NSUnderlyingError=0x2820ad3e0 {Error Domain=NSCocoaErrorDomain Code=134100 "The managed object model version used to open the persistent store is incompatible with the one that was used to create the persistent store." UserInfo={metadata={ NSPersistenceFrameworkVersion = 1338; NSStoreModelVersionChecksumKey = "qcPf6+DfpsPrDQ3j1EVXcBIrFe1O0R6IKd30sJf4IrI="; NSStoreModelVersionHashes = { NSAttachment = {length = 32, ... Strangely, the only way I could replicate this issue in the simulator was by running the latest version of the app followed by reverting to an older version, a scenario unlikely to occur in a real-world setting. This raises the question: How could this situation arise with actual users, considering they would typically move from an old to a new version rather than the reverse? I am reaching out to the community for insights or advice on this matter. Has anyone else encountered a similar problem during the Core Data migration process? How did you resolve it?
