Xcode – Asset validation failed, NSLocalizedRecoverySuggestion=Invalid Executable. The executable hermes.framework/hermes' contains bitcode

create a file in the ios folder with name `

handle_bitcode.sh`

use this commnad

touch handle_bitcode.sh

and then run this command

sudo chmod +x handle_bitcode.sh

and paste this script
