/Users/joelaws/Workspace/kratos/Pods/TwitterCore/iOS/TwitterCore.framework/Modules/module.private.modulemap:1:29: Rename 'TwitterCore.Private' to ensure it can be found by name

Steps to reproduce the behavior

2. Setup a project and Podfile that depends on TwitterCore
3. Compile the main target and the TwitterCore cocoapod
4. see the build warnings
