At the moment, there are two iOS APIs partially implemented, GameCenter
and Storekit. Both use the same model of asynchronous calls explained
below.

ARKit and Camera access are also provided as plugins.
Accessing plugin singletons
---------------------------
To access plugin functionality it's first required to use check if plugin
is exported and available with `Engine.has_singleton` function. After
that calling a `Engine.get_singleton` will return a singleton. This
is an example of how this can be done:
::
var in_app_store
func _ready():
if Engine.has_singleton("InAppStore"):
in_app_store = Engine.get_singleton("InAppStore")
# Plugin setup
else:
print("iOS IAP plugin is not exported.")
