Errors after upgrading to Swift 1.2

My function:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: NSDictionary)

Shows this error:

Objective-C method 'application:didReceiveRemoteNotification:' provided by method 'application(:didReceiveRemoteNotification:)' conflicts with optional requirement method 'application(:didReceiveRemoteNotification:)' in protocol 'UIApplicationDelegate'

I saw on another post that it fixes by just "rewriting" the methods name. What does it mean? Change the name? Delete it and write it again?

Replace NSDictionary with [NSObject : AnyObject].

Swift 1.2 further moves away from its Objective-C foundations by remapping some class methods from the NSDictionary type to the native Swift [NSObject: AnyObject] type.

Change your method header to this:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject: AnyObject])

You can fix other errors of this sort by using the Swift conversion tool, which can be found in the Edit menu under "Convert" (Edit -> Convert -> To Latest Swift Syntax...).

I assume what is meant by "rewriting" the method header in your other source is deleting the line and typing application(, then selecting the didReceiveRemoteNotification option from the popup menu and allowing autocomplete to do the rest.
