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..

まず tns build ios --clean --for-device --env.aot --env.report --env.hiddenSourceMap ... --release コマンドを再現し、一覧にある NativeScript フレームワークについて Xcode の警告を確認します。release ビルドのシンボルストリッピングと署名設定を、参照されている Xcode のガイダンスと比較します。完了条件は、デバッグシンボルが release IPA に含まれるかどうかを説明し、署名を壊さずに警告を除去する、サポートされている変更を定義することです。
