IOS – How to acquire SDKs to build target pre-8.0 iOS

iosxcode

I have installed XCode 6 and it came with the iOS 8 SDK but i need to test on devices still running 7.1 and cannot figure out how to get the iOS 7 SDK now without downloading an older version of XCode than I already have installed. Where can I find the previous SDKs and can I install them in my newer version of XCode?
