APN registration failing in development

My app is unable to register for push notifications with the user in development mode. (Production is working fine for some reason, on the same code.)

Authorization is requested and accepted just fine. Notification Center settings also show that authorization was given, but neither application(didRegisterForRemoteNotificationsWithDeviceToken:) or application(didFailToRegisterForRemoteNotificationsWithError:) is ever called.
