Ad-hoc testing on 5.1.1 using Xcode 7.3

Is it possible to create Ad-Hoc builds from Xcode 7.3 to test on an iPad running 5.1.1? Is this supported by Apple any longer? Currently I can not use Testflight as I cannot download the App onto the 5.1.1 device as it requires the device to be running iOS 8.0+. I'm trying to release the app onto the store using Xcode to deploy for 5.1.1 and have had to get an older version of Xcode (6.4) to do this but I cannot test using Ad-Hoc build as I cannot find a way to deploy it onto the older devices. I can run it on the device using Xcode 6.4. I've had to deploy it on to the store to do my testing and have discovered the app won't open, hence the need for ad-hoc testing to diagnose the problem. The issue i'm getting from the diagnostic and usage file from the 5.1.1 device is : "Dyld Error Message: Library not loaded: System/Library/Frameworks/************.framework/************". I assume its something to do with linking the ************ framework when deploying to the App Store as it runs fine when testing directly onto the device. So i'm not sure what Xcode does differently when linking libraries when your run it directly on the device to deploying it onto the store.
