Why would the delegate property on the TimedButton class need to be an @IBOutlet?

It doesn’t need to be an IBOutlet, but if you’re writing reusable controls like this, it helps to allow them to be configured within Interface Builder.

Hi Ben,

Great episode as always, I am a recent subscriber to your screencasts and wondered if it would possible to include the 'before' project in Git? I like to follow along whilst watching but the project in Git is always the completed version. Railscasts had a nice approach for before and after projects on a screencast: https://github.com/ryanb/ra...

I’ve done this on a few episodes in the past, I just tend to forget. I will try to remember to do this more in the future. Thanks for the comment!

You mentioned that in iOS 9 you don't need to deregister from NSNotificationCenter in `deinit`. Do you have a link for more information about this?

“In OS X 10.11 and iOS 9.0 NSNotificationCenter and NSDistributedNotificationCenter will no longer send notifications to registered observers that may be deallocated. If the observer is able to be stored as a zeroing-weak reference the underlying storage will store the observer as a zeroing weak reference, alternatively if the object cannot be stored weakly (i.e. it has a custom retain/release mechanism that would prevent the runtime from being able to store the object weakly) it will store the object as a non-weak zeroing reference. This means that observers are not required to un-register in their deallocation method.” https://developer.apple.com... <https: developer.apple.com="" library="" prerelease="" mac="" releasenotes="" foundation="" rn-foundation="" index.html#="" apple_ref="" doc="" uid="" tp30000742="">
