Thanks for your reply. I have already filed a report through Feedback Assistant. Case-ID: 18609190 (Apple DTS incident) Feedback ID: 22081725 The issue was submitted on Feb 28, 2026, but so far there has been no update in Feedback Assistant. The problem is still reproducible in Xcode 26.3 with Release (-O) builds when targeting iOS 16/17/18. Could you please help check whether this Feedback has been routed to the appropriate Swift/Xcode engineering team, and whether there is any information about which future Xcode version might include a fix? Thank you very much for your help.
