    So, after pod install in my ios folder and yarn ios, I got all these errors saying stuff was duplicated.
error: Multiple commands produce '/Users/angelodias/Library/Developer/Xcode/DerivedData/gobarber-fbmfdupvkffmushjnumgyoenfzpe/Build/Products/Debug-iphonesimulator/gobarber.app/Zocial.ttf':
1) Target 'gobarber' (project 'gobarber') has copy command from '/Users/angelodias/GIT/bootcamp/gobarber/node_modules/react-native-vector-icons/Fonts/Zocial.ttf' to '/Users/angelodias/Library/Developer/Xcode/DerivedData/gobarber-fbmfdupvkffmushjnumgyoenfzpe/Build/Products/Debug-iphonesimulator/gobarber.app/Zocial.ttf'
2) That command depends on command in Target 'gobarber' (project 'gobarber'): script phase “[CP] Copy Pods Resources”

I have no knowledge of how XCode works, so I went with the good and old try-and-error to make things good.
Below, the solution:
SOLUTION

You WILL need a new React Native project. There's no way (until now) to fix this on old ones.
Remove /* [CP] Copy Pods Resources */ whole section.
This might break other stuff, but for me it worked, as the project was duplicating fonts and they don't actually break the app.
Actual code I deleted:

If not good, try:
Cleaning all pods and reinstalling:
pod cache clean --all # will clean all pods
rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
rm -rf ~/Library/Developer/Xcode/DerivedData/*
cd ios
pod deintegrate
pod setup
pod install


Selecting the ID of the [CP], this case was C07AC2465709E2CC73AB903F and removing all it's ocurrences.

Then the first step.
Other info

Now, for myself, this was the step by step error handling:
After each topic I yarn + yarn ios. If worked, git commit.

Installing empty React Native + TS
pod Install
Copying file structure from base project (the one erroring)
Changing Package.json
pod install
changing app.jsx and index.js
Running link
