Fixed, for some reason the ios project was setup in "Release mode". I did the change in Xcode -> edit schemes

Then In Run Section, The build configuration was in "release", did the change to "Debug". Close xcode then in vscode, run again: npm start npm run ios After that, the app runs well again and able to send logs to debugger. And if someone don't know, I wasn't able to see the logs inmmediately, as I read before in some posts around internet about RN >= 0.77, it is necessary to have some third-party debugger, but i wanted to put it simple, just downloaded Chrome browser first, and then run the npm commands. In simulator, once the app is launched, press "j" key, to see the option "open dev tools", with that the chrome dev tools will open and you'll see the logs. I were about 4 days with this trouble,I hope these details can help others
