iOS 7 no longer working with XCode 4.6.3

Question

I have XCode version 4.6.3 and have just recently upgraded the OS on my iPhone 4 to iOS 7. When I try to run my code on my device I get the following error:

Xcode cannot run using the selected device.

No provisioned iOS devices are available with a compatible iOS version. Connect an iOS device with a recent enough version of iOS to run your application or choose an iOS simulator as the destination.

In Organizer I'm seeing the following message:

The version of iOS on "My Phone's Name" is not supported by this installation of the iOS SDK. Please restore the device to a version of the OS listed below, or update to the latest version of the iOS SDK; which is available here.

The here link just prompts me to login to Member Center and doesn't drop me off anywhere about the latest SDK.

My deployment target is iOS 6.1, I don't want to raise that to 7.0 as the majority of our users are on pre iOS 7. I am running OS X version 10.8.3, can I upgrade my SDK? Do I have to? How can I make it so my SDK is compatible with iOS 7 and pre iOS 7 devices?

Answer 1

Developing with iOS7 requires that you upgrade to Xcode 5, which you can find free in the Mac App Store.

You'll still be able to keep your deployment target below 7.0 with Xcode 5.

If you don't have a dev iPhone with iOS 6.x you can go into Xcode > Preferences > Downloads to install the iOS6 simulator, command line tools, and any additional documentation.

Update 1

If you update your phone to iOS 7.1, you will also be required to update your version of Xcode to 5.1
