App can’t contain standalone executables or libraries, other than a valid CFBundleExecutable of supported bundles

[ArvindSeth]

We are using SocketRocket.framework in our application and while deployment getting error as------ ERROR ITMS-90171: "Invalid Bundle Structure - The binary file 'appname.app/Frameworks/SocketRocket.framework/SocketRocket' is not permitted. Your app can’t contain standalone executables or libraries, other than a valid CFBundleExecutable of supported bundles. Refer to the Bundle Programming Guide at https://developer.apple.com/go/?id=bundle-structure for information on the iOS app bundle structure. -----

Here are some info regarding the SocketRocket.framework structure in our project-

SocketRocket.framework added in main.bundle with selected target membership and required
Added as embed & Sign under Target> general> frameworks, Library & embedded content
Added in Link binary with libraries & embedded frameworks only under Build Phase tab.

A point to mention that we have noticed: while updating Carthage, if building scheme for static SocketRocket.framework runs first, then we will not get any error, but when it build dynamic SocketRocket.framework first, we will get ERROR ITMS-90171.

is that the cause for this issue, if yes please give us a solution or help us to find main cause.

Also mentioning the build log below -
