Ios swift – DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead

Trying to run a flutter app after latest Xcode and iOS 17 update and get the following error "DT_TOOLCHAIN_DIR cannot be used to evaluate LIBRARY_SEARCH_PATHS, use TOOLCHAIN_DIR instead"

# platform :ios, '11.0'

    end
end
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end

Anyone know how I can modify this to work?
This seems to happen that there’s some sort of error after upgrading Xcode.

    Try using this command on a console:

    find . -type f -exec grep -l 'DT_TOOLCHAIN_DIR' {} ; 
| while IFS= read -r file; do sed -i '' 
's/DT_TOOLCHAIN_DIR/TOOLCHAIN_DIR/g' "$file"; done

    It will solve your issue.

    We are waiting for the cocoapod maintainers to make a new release with this fix included.

    Until then you can try another alternative fix from this comment or this comment or point the cocoapods gem in your Gemfile to the cocoapods git repo and it’s master branch.
