I've noticed that despite Apple stating Xcode 16's minimum deployment target is iOS 13, I was able to set my app's minimum target to iOS 12, build it, and successfully upload it to TestFlight. I've tested the app on iOS 12 devices, and it functions normally. Given that updating to Xcode 16 will be mandatory after April 24th, I have a few questions: Is it intentional that Xcode 16 still allows targeting iOS 12? Will Apple continue to support this capability for iOS 12 devices in the future? Are there any plans to restrict or block apps targeting iOS 12 in upcoming Xcode updates? I'm seeking clarification on whether it's safe to continue supporting iOS 12 in our apps or if we should prepare for potential changes. Any insights from the Apple development team would be greatly appreciated.

As verifyReceipt has been deprecated this time, I am trying to verify the receipt using Get Transaction History Endpoint. Apparently, Apple's official document says it will return the value for a single transaction if you request it to the endpoint, but it keeps returning the value by combining all the information about different Transaction IDs. If there are developers who know about this, please answer. Also, please let me know if anyone knows how to verify the receipt using this endpoint.

I understand from the recent Apple Developer News that Korean developers are now required to register a URL to receive notifications from the Apple server when creating or modifying a Sign in With Apple Service ID. However, it is not clear whether simply registering the URL is sufficient, or if it is also mandatory to implement the real-time processing of those notifications. I am inquiring whether the processing part is also a mandatory requirement.
