if i download Xcode 15, will my projects migrate over to Xcode 15 without any problems? if i may have issues, i just won't download Xcode 15.

I keep getting the error: "Embedded binary is not signed with the same certificate as the parent app. Verify the embedded binary target's code sign settings match the parent app's." I don't know why. The only thing I can think of is that my iPhone is signed into a different Apple ID than the one I'm using for my Xcode signing. But I'm not sure because I can't find any info about it online.
