I recently upgraded to Xcode 6. Everything works fine, but I got a new warning indicating that I am updating iOS Deployment Target to 8.0. Bellow is a screenshot of a message.

However, I do not want to update the deployment target because I want to support any device with OS version 7.0 and higher.
How to ignore this warning? Or maybe the iOS Deployment Target setup has nothing to do with the lowest version of the OS that my application can support?
