setObject equivalent in Swift

I have obj-c code

[dictionary setObject:[[notification object] objectForKey:@"key"] forKey:@"anotherKey"];

how can I translate this to swift ? Notification is NSNotification object

I tried 

dictionary.setValue(notification.valueForKey("key"), forKey: "anotherKey")

but app crashes with error (sorry for image, paste doesn't work)

The pure Swift equivalent is

dictionary["anotherKey"] = notification.object?["key"]

If notification.object or the key key does not exist no object will be assigned.

Note:

Never use valueForKey / setValue:forKey: unless you have a distinct idea why you are using KVC.

dictionary["anotherKey"] = (notification.object!["key"] as! String)

How about making your dict a var (not let) and doing this:

dictionary["anotherKey"] = [[notification object] objectForKey:@"key"]

Try this may be it helps you:

dictionary .setValue(notification.object["key"], forKey: "anotherKey")
