Swift toolkit for passing messages between iOS apps and extensions
What is SwiftyMessenger?
SwiftyMessenger is a Swift toolkit for passing messages between iOS apps and extensions. It creates a bridge between container app and iOS extensions. SwiftyMessenger archives messages in files which are written to the application’s shared App Group. SwiftyMessenger resembles interprocess communication between the app and the extension without a interprocess communication.
It also supports CFNotificationCenter Darwin Notifications in an effort to support realtime change notifications. When a message passed, interested parties can listen and can be notified (almost instant) of these changes on both side.
