提交appstore 时碰到这个总是​ERROR ITMS-90171？

ERROR ITMS-90171: “Invalid Bundle Structure - The binary file ‘/otherSDK/libWeChatSDK.a’ 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.”

我这个.还是昨天下载的，无支付版本的。请问一下，有解决办法吗？
