Answer 1

When your app comes back from the background, app delegate events will arrive in this order:

• applicationWillEnterForeground(_:)
• application(_:open:options:)
• applicationDidBecomeActive(_:)

Thus it is easy to know by the time the application becomes active whether this is because of a URL scheme or not.
