My apps are legacy codebases still using AppDelegate instead of SceneDelegate. According to TN3187: Migrating to the UIKit scene-based life cycle, apps should migrate to the scene-based lifecycle. I have the following questions: Is there a specific timeline or deadline for when this migration will be enforced? Will there be deprecation warnings before the assert is triggered? I've tested my app with Xcode 27 beta, and it's not showing any errors or warnings related to this requirement. Based on this, I'm assuming this scene delegate migration may not be relevant for Apple's yearly requirement to submit new apps with the latest iOS SDK, and won't be enforced in April when "apps uploaded to App Store Connect must be built with Xcode 27 or later using an SDK for iOS 27." Can someone confirm if this understanding is correct?

I'm working on updating our iOS app for the latest Xcode version and noticed the new UIDesignRequiresCompatibility key requirement in Info.plist for apps targeting older iOS designs (without liquid glass). Is there an official timeline for when this compatibility key will be deprecated/removed so that we can plan our liquid glass design changes?

We are experiencing a significant issue with the SKStoreReviewController.requestReview(in: scene) API that may be affecting our app's rating collection on the App Store. Issue Details: Development Environment Behavior: The rating popup displays consistently in development builds (as expected per documentation) API calls are functioning correctly in our test environment Production Environment Issue: We have observed a major drop in App Store ratings received between January and July 2025 The same codebase that works in development is deployed to production Analytics Confirmation: Before calling SKStoreReviewController.requestReview() in production, we fire analytics tags to track API invocations Our analytics show no drop in the number of times this API is being called This confirms the API is being invoked correctly in production Discrepancy: Despite consistent API calls (confirmed by analytics), we see a major drop in actual ratings received on the App Store This suggests the rating popup may not be displaying to users in production, even though the API call is successful Questions: Are there any known issues with SKStoreReviewController.requestReview() API between January-July 2025? Are there any iOS version-specific issues that might prevent the popup from appearing in live app? What debugging steps do you recommend to identify why the API calls aren't resulting in visible rating prompts?

We are testing our existing live build, which was prepared with Xcode 16.2, on iOS 26 beta for experience assurance and found that the [[UIDevice currentDevice] systemVersion] API is returning iOS 19 instead of the expected version iOS 26. Has anyone else observed this issue?
