Missing Required Modules in Swift framework

Question

I built a swift framework with two Objective-C classes. After I released a framework, it works on my environment. But I imported this to another environment, but it didn't work. "Missing Require Modules..." Here is my module.

module RSAUtil [system] {
    header "RSAUtil.h"
    export *
}

module NetworkTool [system] {
    header "NetworkTool.h"
    export *
}

module openssl [system] {

    header "OpenSSL_Lib/include-ios/openssl/bio.h"
    header "OpenSSL_Lib/include-ios/openssl/opensslv.h"
    header "OpenSSL_Lib/include-ios/openssl/rsa.h"
    header "OpenSSL_Lib/include-ios/openssl/ssl.h"
    header "OpenSSL_Lib/include-ios/openssl/err.h"
    header "OpenSSL_Lib/include-ios/openssl/pem.h"

    export *
}

I tried many solutions but failed. Can anyone help me? Thanks.
