I sincerely apologize for the delayed response! I have also confirmed on my end that the combination of Xcode 26.1.1 and iOS 26.1 works properly without any crashes. Thank you to everyone who provided comments and to those who worked on addressing this issue.

Hello, I am also encountering the same issue and struggling to resolve it. I have checked the link for Dynamic Library Standard Setup for Apps and added "/usr/lib/swift" to the "Runpath Search Paths," but it did not solve the issue. Could you please provide the exact steps to resolve this?

Thank you for your response. Here is the information we have from the server logs: When app redirection using Universal Links fails, the HTTP link is opened in the browser. We have detected statistics from Google Analytics showing that multiple devices have accessed the relevant page. However, we do not have specific log files at this time. Since we do not have access to the device, we cannot obtain the logs immediately. However, we will share them as soon as we can retrieve them.

Thank you for your response. I have rechecked the app's implementation, and it seems there are no issues. Also, we know from the server logs that a bug is occurring, but I am unable to reproduce this bug on my end, so I cannot submit a swcuilt file. I apologize for the limited information I can provide, but I would be grateful for any hints you could offer to help resolve this issue.
