SwiftyMessenger

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.

Requirements

SwiftyMessenger Version	Minimum iOS Target	Minimum watchOS Target	Swift Version
0.4.0	iOS 10	watchOS 3.0	Swift 5.x
0.2	iOS 9	watchOS 2.0	Swift 4.2
0.1	iOS 9	watchOS 2.0	Swift 4.1

NOTE

SwiftyMessenger can only work with App Group identifiers and Entitlements.

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate SwiftyMessenger into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!

target '<Your Target Name>' do
	pod 'SwiftyMessenger', '~>0.4.0'
end

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

brew update
brew install carthage

To integrate SwiftyMessenger into your Xcode project using Carthage, specify it in your Cartfile:

github "abdullahselek/SwiftyMessenger" ~> 0.4.0

Swift Package Manager

Modify your Package.swift file to include the following dependency:

.package(url: "https://github.com/abdullahselek/SwiftyMessenger.git", from: "0.4.0")

XCFramework

XCFrameworks require Xcode 11 or later and integration is very similar to integration of .framework format. Please use script scripts/build-framework.sh to generate binary SwiftyMessenger.xcframework archive that you can use as a dependency in Xcode.

SwiftyMessenger.xcframework is a Release (Optimized) binary that offer best available Swift code performance.

Usage

Initialization

messenger = Messenger(withApplicationGroupIdentifier: "group.com.abdullahselek.swiftymessenger", directory: "messenger")

Passing message

messenger.passMessage(message: ["selectedCell": title], identifier: "selection")

Reading message

if let message = messenger.messageForIdentifier(identifier: "button") as? [String: Any] {
	let buttonTitle = message["buttonTitle"] as? String
}

Listen message changes with identifier

messenger.listenForMessage(withIdentifier: "button") { message in
    guard let message = message as? [String: Any] else {
        return
    }
    let buttonTitle = message["buttonTitle"] as? String
}

Support for WatchConnectivity

SwiftyMessenger suports WatchConnectivity provided by Apple on watchOS extensions.

Here are two little notes you need to know if you want to use WatchConnectivity support in your app:

MessengerSession is a singleton subclass that supports listening for WatchConnectivity messages. It can be used to listen Messenger messages you expect to receive from the WatchConnectivity framework. Be sure to activate the session once your listeners are set so that you can begin receiving message notifications.
You can use MessengerSessionContextTransiting when creating your messenger, but it can easily overload the pipeline by sending too many messages at once.

Transiting Types

You can find 5 available types under TransitingType.

file (Message transiting by archiving and unarchiving messages that are written and read to files)
coordinatedFile (Uses FileCoordinator)
sessionContext (Support for the WatchConnectivity framework's Application Context)
sessionMessage (Support for the WatchConnectivity framework's real time message passing ability)
sessionFile (Support for the WatchConnectivity framework's file transfer ability)
