How to download an iOS 6 app that can run on iOS 7 with iOS legacy Look
I had the same problem and with this solution everything worked fine. so try it.
open Finder and find your Xcode 4.6.3 package right click and select "show package contents" go to Contents / Developer / Platforms / iPhoneOS.platform / Developer / SDK / you will find a folder called iPhoneOS6.1.sdk copy it Now that we got it, let's paste it into the same directory in Xcode 5:
open Finder again and find your Xcode 5 package right click and select "show package contents" go to Contents / Developer / Platforms / iPhoneOS.platform / Developer / SDK / you will find the iPhoneOS7.0.sdk folder here (this is the "last "at the time of writing) paste iPhoneOS6.1.sdk folder here and install basedk in target xcode setup on ios 6.1.

There are some issues here, you cannot use the iOS 6 SDk to push updates as Apple only allows pushing the iOS 7 SDK build. Also you need to use at least Xcode 5.1 to ship.
So, you will need to convert the app to the iOS 7 SDK, which will make it look like iOS 7. Then you will need to write you the look and feel of the UI controls you want to see in iOS 6 (this will be very difficult to do for all controls , especially UIPickerViews
).
Just make the app look good on iOS 7 and use an external proxy to make it look good on iOS 6, perhaps easier.
