Edit app.entitlements file during build phase

Question

I have several target in my Xcode project each of them having an associated domain but a different one.

I'd like to have the same entitlements file for all my target and having a script with PListBuddy to change the value the domain.

I already have a script that works that I launch during the Build Phases that edit the file correctly :

case $TARGET_NAME in
  "EN6") fireBaseUrl="FOO.app.goo.gl";;
  "ES5") fireBaseUrl="BAR.app.goo.gl";;
  "SVT-C4") fireBaseUrl="FOOFOO.app.goo.gl";;
  "PC5") fireBaseUrl="BARBAR.app.goo.gl";;
  *) fireBaseUrl="FOOBAR.app.goo.gl";;
esac

# Universal links used by Firebase
associatedDomainKey="com.apple.developer.associated-domains"
/usr/libexec/PlistBuddy -c "delete ${associatedDomainKey}" app.entitlements
/usr/libexec/PlistBuddy -c "add :${associatedDomainKey} array" -c "add :${associatedDomainKey}:0 string applinks:${fireBaseUrl}" app.entitlements

The problem is that I have a "The executable was signed with invalid entitlements." error when installing the app on a device.

I guess it's because after being edited the entitlements file doesn't corresponds to the entitlements included in the provisioning profile anymore.

Do you know if there is a way to do what I want ? Using fastlane, shell script or anything... (I have 40 targets so I'd really like to get only one entitlements file for all of them)

Xcode creates an .xcent with your entitlements before signing your app. You can add a Run Script phase as a last step to modify it using PlistBuddy, like this:

echo "Updating ${TARGET_TEMP_DIR}/${FULL_PRODUCT_NAME}.xcent"
/usr/libexec/PlistBuddy -c "add com.apple.developer.icloud-container-environment string Production" "${TARGET_TEMP_DIR}/${FULL_PRODUCT_NAME}.xcent" || exit 1
