哪个版本的XCode将支持iOS 3.0？

Question

I want my app to support the largest audience possible. I am thinking this would be iOS 3.0 to iOS 7.0. I originally wrote the app using XCode 5.0 but because I used storyboarding I could only support users that had iOS 5.0 or higher at the time. At this point, I am thinking of reworking the app so it no longer uses storyboarding and using a lower version of XCode. I am also wondering how to support iOS 7.0 as while supporting iOS 3.0 users?

Was wondering if someone could point me in the right direction?

Thanks in advance!

There is no single version of Xcode that will support both iOS 3.0 and 4" iOS 7 devices.

Only Xcode versions 4.4 and earlier can generate armv6 code for iOS 3 devices. Later ones cannot.

And Apple no longer allows submitting iPhone apps without 4" display support, which requires Xcode 4.5 or later, and building with the iOS 6 SDK or later. The lowest iOS version which Xcode 5 and the iOS SDK 7 supports is iOS 4.3.

Some iOS developers have reported success using the OS X lipo command-line tool to combine binary slices from both Xcode 4.4 and Xcode 5, but this usage is unsupported.
