Allow main app to share local data and keychain with it's app extensions

ParseSwift doest not allow sharing local data with it's extensions

Parse-IOS Objective-C SDK allows main iOS app to share local data like PFUser.current, PFInstallation.current and e.t.c with its app extensions like share extension, broadcasting extension and e.t.c.. Please add support for this feature for ParseSwift.

Feature / Enhancement Description

When this feature enabled, ParseUser.current and ParseInstallation.current should return the same value from the main app if it is called inside app extension. The main app should share keychain with its' extensions.

Example Use Case

Main app logs in user and launches broadcasting extension. Broadcasting extension calls ParseUser.current and gets the same user logged in in the main app. Broadcast extension is aware of the current user from the main app and shares keychain.

This was already added in parse-community#378. In the Swift SDK, all .current items are securely stored in the Keychain, so you will need to properly enable keychain sharing via access groups as well as add the correct Signing & Capabilities. Be sure to look through the differences between App Groups and Keychain Access Groups and how to use them together in the posted link.

The way these are stored in the Swift SDK is a lot different than the Objective-C SDK and the Swift SDK doesn't have issues like: parse-community/Parse-SDK-iOS-OSX#1648 or parse-community/Parse-SDK-iOS-OSX#1220
