I want to get all the classes in my project userLocation variable. How can I identify as a global? Is that reasonable? Do I have to define each class separately? Also I would like to access the application in the background too.
Thanks

Never use global variables in general (in any programming langage), that’s bad architecture/design in general.
You should use the Singleton Pattern (see Apple Doc) for such stuff of gathering common information or features global to the application. Use it parcimoniously (using it everywhere without justification is also bad design)
In the case of the userLocation, you can anyway get the latest user location retrieved by the GPS using
CLLocationManager‘slocationproperty anyway, so there is no need for a global variable or a singleton for this case.
