I managed to create an app which turns the phone into a beacon emitter.
It works fine on xcode (Swift) and phonegap .
The next step for me is making it work in the background as a beacon (I'm developing for iOS 10).
I found similar questions to this online but all of them were out of date ie old ios , objective-C and outdate plug-ins
would really appreciate it if someone can provide me with a working example or guide me on what to change in my code for both an xcode s(wift) and phonegap
Xcode (Swift 3)

for both codes , the location updates and background fetch are checked in the background capabilities for the target. Also , Privacy - Location Always Usage Description is added on both playlists
