I found the solution.
- Make sure that you have linked your project with Foundation.framework and CFNetwork.framework
- Make sure the Foundation framework include is before CFNetwork.
- If you already have this configuration in your project then once un-link these frameworks, clean your project and link them again.
My project has been working well after this, hope yours does as well.
