CocoaPods multiple modules in one single Pod, one for static lib, one for swift

Question

I'm creating a Pod for iOS which provides crypto APIs using OpenSSL under the hood.

So far I've managed to call OpenSSL from Swift, but it seems like Swift API and OpenSSL API is mixed up, living in a same OpenSSL module.

Is it possible to create OpenSSL module for C OpenSSL API, and OpenSSLTest2 module for Swift API? Also, I'd like OpenSSL module to be private if possible.

Here's my podspec.

Pod::Spec.new do |s|
  s.name             = 'OpenSSLTest2'
  s.version          = '0.1.0'
  s.summary          = 'A short description of OpenSSLTest2.'
  s.description      = <<-DESC
TODO: Add long description of the pod here.
                       DESC

  s.homepage         = 'https://github.com/yshrsmz/OpenSSLTest2'
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { 'yshrsmz' => 'mymailaddress' }
  s.source           = { :git => 'https://github.com/yshrsmz/OpenSSLTest2.git', :tag => s.version.to_s }

  s.swift_version = '4.2'
  s.platform = :ios
  s.ios.deployment_target = '8.0'

  # if I change here to 'OpenSSLTest' or something, it won't compile 
  s.module_name = 'OpenSSL'
  s.source_files = 'OpenSSLTest2/Classes/**/*.swift', 'OpenSSLTest2/OpenSSL/include/**/*.h'
  s.header_dir = 'openssl'
  s.public_header_files = 'OpenSSLTest2/OpenSSL/include/openssl/*.h'
  s.preserve_paths = 'OpenSSLTest2/Classes/OpenSSL/module.modulemap'
  s.libraries = 'crypto', 'ssl'
  s.vendored_libraries = 'OpenSSLTest2/OpenSSL/lib/libcrypto.a', 'OpenSSLTest2/OpenSSL/lib/libssl.a'

  s.pod_target_xcconfig = {
      'SWIFT_INCLUDE_PATHS' => '$(PODS_ROOT)/OpenSSLTest2/OpenSSL/module $(PODS_TARGET_SRCROOT)/OpenSSL/module',
      'LIBRARY_SEARCH_PATHS' => '$(PODS_ROOT)/OpenSSLTest2/OpenSSL/lib'
  }
end

this is the modulemap for OpenSSL.

module OpenSSL [system] {
    header "openssl/conf.h"
    header "openssl/evp.h"
    header "openssl/err.h"
    header "openssl/bio.h"
    header "openssl/ssl.h"
    header "openssl/md4.h"
    header "openssl/md5.h"
    header "openssl/sha.h"
    header "openssl/hmac.h"
    header "openssl/rand.h"
    header "openssl/ripemd.h"
    header "openssl/pkcs12.h"
    header "openssl/x509v3.h"

    export *
}

also this is the complete repository.

thanks.

I've ended up with creating a framework which only contains OpenSSL(with modulemap), and then use that framework as vendored_frameworks
