Current Behavior

I successfully upgraded from Capacitor v3 to v4 following the step-by-step Upgrade Guides on the Capacitor Documentation. But when I run npx cap sync ios or ionic cap sync ios, it run into the following error

✖ Updating iOS native dependencies with pod install - failed!
✖ update ios - failed!
[error] 
        [!] Invalid `Podfile` file: cannot load such file --
        /Users/admin/CapProject/node_modules/@capacitor/ios/scripts/pods_helpers.
        
        #  from
        /Users/admin/CapProject/ios/App/Podfile:1
        #  -------------------------------------------
        >  require_relative '../../node_modules/@capacitor/ios/scripts/pods_helpers'
        #
        #  -------------------------------------------

it seems the node_modules/@capacitor/ios/scripts/pods_helpers file is missing in the current release.

Expected Behavior

Should install, copy and sync dependencies for ios.

How did you migrate? That step is not documented for the step to step guide, should only happen if you used npx cap migrate command.

As workaround you can remove the require_relative '../../node_modules/@capacitor/ios/scripts/pods_helpers' line and this block

post_install do |installer|
    assertDeploymentTarget(installer)
  end

@capacitor/ios 4.0.1 is now out with the fix, you can run migrate command again (update @capacitor/cli to 4.0.1 first) and it will add the failing code if you removed it and fix other issues it caused on android themes
