Answer 1

1. To fix the first error try:
`rm -rf ./node_modules`
`yarn install` // or npm install
`cd ios && rm -rf ./Pods && rm -rf Pofile.lock && pod install && cd ..`
`npx react-native run-ios`
2. To fix the second error:
try to remove/comment flipper in Podfile
Make sure you have excluded the arm64 architecture for simulators
Note: I had a PhaseScriptExecution error showing up after upgrading Xcode to 13.1:
dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.67.dylib.
I fixed it with:
brew update and brew install.
If still not working please attach to your question:
full content of Podfile
result of pod install command
full log for react-native run-ios command
Your errors are too generic to debug without the full the full error log.

Answer 2

I always run into this problem. Follow these steps to remove the error.
From the root of the project, do cd ios
pod deintegrate
pod install
If this doesn't help then remove node_modules and then try above after npm install or yarn install, as follows.
On the root of the project, do the following
rm -rf node_modules
npm install / yarn install
cd ios
pod deintegrate
pod install
cd ..
react-native run-ios
