Use iOS 10.3.3 with Xcode Version 8.2.1?

Question

I am using Xcode Version 8.2.1 and cannot upgrade because I am working off of a 2008 MBP and the latest versions of Xcode are not supported.

I trying to run a project on an iPhone 5 which is running iOS 10.3.3 however, when i try to run the project from Xcode I get the following error message:

I checked the device support folder located at: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/

and I see that the 10.3 folder is not present

Is there a way I can add a folder for 10.3 device support? Is there a place I can download it and add it into my Xcode?

If this is not possible, does anyone know a way to downgrade to an unsigned iOS firmware such as 10.2 or lower?

You can download the Xcode 8.3 separately(or get it from here :https://gist.github.com/steipete/d9b44d8e9f341e81414e86d7ff8fb62d#gistcomment-2041802) and get the 10.3 SDK from that which resides in Developer/Platforms directory. Reboot system as well as XCode and select SDk in settings as 10.3
