iOS Umbrella Framework - codesign problem - ios

Question

I have an Umbrella Framework distributed throughs Cocoapods as vendored framework and compiled in release mode.
It works perfectly with simulator, but I have a problem with the code sign on the sub-framework nested in the umbrella layer.
This is the error:
dyld: Library not loaded: #rpath/Subframework.framework/Subframework
Referenced from: /private/var/containers/Bundle/Application/02AD328F-9E78-4D53-9C39-0C8639B00D81/sdkInteTest.app/Frameworks/Umbrella.framework/Umbrella
Reason: no suitable image found. Did find:
/private/var/containers/Bundle/Application/02AD328F-9E78-4D53-9C39-0C8639B00D81/sdkInteTest.app/Frameworks/Umbrella.framework/Frameworks/Subframework.framework/Subframework: code signature in (/private/var/containers/Bundle/Application/02AD328F-9E78-4D53-9C39-0C8639B00D81/sdkInteTest.app/Frameworks/Umnrella.framework/Frameworks/Subframework.framework/Subframework) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.
Then, if I launch the application to sign the sub-framework with the following script:
pushd ${TARGET_BUILD_DIR}/${PRODUCT_NAME}.app/Frameworks/Umbrella.framework/Frameworks
for EACH in *.framework; do
echo "-- signing ${EACH}"
/usr/bin/codesign --force --deep --sign "${EXPANDED_CODE_SIGN_IDENTITY}" --entitlements "${TARGET_TEMP_DIR}/${PRODUCT_NAME}.app.xcent" --timestamp=none $EACH
done
popd
I get this error:

The Solution
The problem is that the script was starting when the pod wasn't already attached.
The script should be run when all the pod jobs are done.
I wrote a full guide to build an iOS Umbrella framework!
The solution I found is the following:
1) Step one:
In the podfile of the integration project (not the umbrella project) add the following line of code where you add dependencies:
script_phase :name => 'Sign', :script => './sign.sh'
like this:
target 'yourTarget' do
# Pods for sdkInteTest
#your pods goes here
script_phase :name => 'Sign', :script => './sign.sh'
end
2) Step two:
Than in the terminal at the root of your test Integration project:
In the terminal type:
touch sign.sh
chmod 777 sign.sh
open sign.sh
And in the script file add this code:
echo "Signing subframeworks"
pushd "${TARGET_BUILD_DIR}"/"${PRODUCT_NAME}".app/Frameworks/YOURFRAMEWORKNAME.framework/Frameworks
for EACH in *.framework; do
echo "-- signing ${EACH}"
/usr/bin/codesign --force --deep --sign "${EXPANDED_CODE_SIGN_IDENTITY}" --entitlements "${TARGET_TEMP_DIR}/${PRODUCT_NAME}.app.xcent" --timestamp=none $EACH
done
popd
echo "BUILD DIR ${TARGET_BUILD_DIR}"
remember to rename your framework name.
In this way you are telling to CocoaPods to run a script phase after the pod installation.
Unfortunately this is a "client" solution, I tried to find a solution to apply at framework level without any luck.
