I don't get any idea why I am getting the following warnings when I tried to upload one of my apps:
App upload warnings (never seen before)
Here's another thread with a discussion of this warning. That thread is long, and the number of folks asking about different facets of these messages makes that thread a bit unwieldily, so I want to reiterate one of my answers here for your clarity:
This is a new warning in Xcode 16 where if you're missing a dSYM, Xcode lets you know in case you aren't expecting that — this is to reduce scenarios where you won't are able to fully symbolicating frames coming from your app's code in crash reports. In some cases, you may not have a dSYM, such as a closed source library from a vendor, and in those cases, the warning is safe to discard.

The project links against one framework and library that was built from my own projects.
Now I believe I need to rebuild them using current version of Xcode.
