Answer 1

From, Session 703 WWDC 2015:

You can continue to use URL schemes when you build your app for iOS 9 and you want to call URL schemes, you will now need to declare them in your apps Info.plist. There is a new key, LSApplicationQueriesSchemes, and here you will need to add the list of schemes you want to are canOpenURL on.
