Hey Ziqiao... Sent over a request to the App review team now. Appreciate the response. Will update here when I learn more as I assume others may have similar experiences between the two implementations.

Any updates on this? Held off on updating to Xcode 15 for our company's project to ensure things were more stable. We have a very large project with thousands of labels. Changing all of these to be programmatically set will be a huge effort. Now having to downgrade to Xcode 14 until this is resolved.
