Problema con SPM y pods en xcode 16 y macos sequoia 15.1.1

When I try to install packages through spm it doesn't find the packages.swift file, and with pods I have problems with Foundation. Trying to install Firebase shows that many pods have issues with double quotes. I don't know if it's my PC using everything updated or what, but I'm having a lot of problems and I haven't been able to reconcile my first application. I don't want to give up, and I would like some advice, since you have managed it, I would appreciate some help. I have followed tutorials, cases of people with similar problems, but it always throws some error.

My pc is mac m1
