Cannot import TestMocks to unit test target in cocoapod library

I am trying to use ApolloTestSupport in unit tests. I want to add generated test models to only unit test target. Generated models doesn’t have @testable import MyApp. so cannot use TestMocks.

apollo-codegen-config.json output segment looks below.

"output": {
    "testMocks": { "absolute": {
      "path": "../../Tests/GeneratedAPI/Mocks"
    } 
   },
    "schemaTypes": {
      "path": "./GeneratedAPI",
      "moduleType": { "embeddedInTarget": { "name": "MyApp" } }
    },
    "operations": {
      "inSchemaModule": {}
    }

I would like to know how to add test mocks to unit target and keep generated model embedded to source target.
