Skipping copy phase strip, binary is code signed IOS

Hello,

We building our IOS release app with following command:

tns build ios --clean --for-device --env.aot --env.report --env.hiddenSourceMap --certificate keychain.p12 --certificatePassword ${IOSKEYCHAINPASS} --release --provision $uuid

We have a lot of this spam like this:

As far as i read thats an IOS linking issue and the Project settings for the (signed) release build is not correct.
It seems it tries to strip debug symbols from the release ipa, which is it not allowed because the ipa is already signed..

1. To remove the Warning it can set that the Project is not doing this on release build (https://stackoverflow.com/questions/5494920/xcode-4-archive-warning-to-skip-copy-phase/7915911#7915911)

But the question overall is why (at least it seems so) debug symbols reach the release .ipa file..

Start by reproducing the tns build ios --clean --for-device --env.aot --env.report --env.hiddenSourceMap ... --release command and inspect the Xcode warnings for the listed NativeScript frameworks. Compare the release build's symbol-stripping and signing settings with the referenced Xcode guidance; done means explaining whether debug symbols reach the release IPA and defining a supported change that removes the warnings without breaking signing.
