Thank you for your response. In conclusion, does this mean that there will be no app crashes caused by UIKit in iOS 26, but there is a possibility of app crashes when building with the SDK provided from iOS 27 onwards?

Thank you for your response. I would like to confirm whether the timing when the app will not be able to launch is when iOS is updated or at another specific time. This will change our response policy. Also, does "your app won’t launch" mean that already distributed apps will also not be able to launch? Or does it mean that newly developed apps will fail to build or be rejected during app review?

Thank you for your reply. Due to character limitations, I have responded in a separate comment. I would appreciate it if you could check it.
