@DTS Engineer Because I just have some iPhones around with OS version 18.5 and test them with Xcode newly compiled app and just happed to see these test results. And I ran some additional tests on iOS 18.6 and results are as follows. Xcode compiled or uploaded app has been tested on iOS 18.6.2 and it's ok. But I did not test on older iOS versions or install on older version then upgrade iOS version and test if it would function well.
