Skipping copy phase strip, binary is code signed IOS

首先重现 tns build ios --clean --for-device --env.aot --env.report --env.hiddenSourceMap ... --release 命令，并检查列出的 NativeScript 框架的 Xcode 警告。将 release 构建的符号剥离和签名设置与所引用的 Xcode 指南进行比较；完成的标准是说明调试符号是否会进入 release IPA，并定义一种受支持的更改，在不破坏签名的情况下移除这些警告。

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..
