ApplicationGroupKit

Applications communication using group identifier.

let appGroup = ApplicationGroup(identifier: "group.id")
appGroup.postMessage("your message", withIdentifier: "key")

appGroup.observeMessageForIdentifier("key") { message in
 ...
}

Usage

The data sharing between applications and extensions require you to enable App Group or Keychain sharing (if using key chain messenger type):

• Configuring App Groups
• Configuring Keychain Sharing

Then you must create an ApplicationGroup object.

let appGroup = ApplicationGroup(identifier: "your.application.group.id")!

You can choose the way the messages are transferred by choosing one of the MessengerType enum value (File, UserDefaults, FileCoordinator, KeyChain, ...)

let appGroup = ApplicationGroup(identifier: "..", messengerType: .UserDefaults)!

⚠️ ApplicationGroup could return nil if you misconfigured application group.

Post a message

Choose a message identifier and post any NSCoding compliant object

appGroup.postMessage("your message", withIdentifier: "key to identify message")

Using subscript

appGroup["key to identify message"] = "your message"

Receive a message

Using the same message identifier you can receive message into callback

appGroup.observeMessageForIdentifier("key to identify message") { message in
 ..
}

Read a message

You can read current value using same message identifier

if let message = appGroup.messageForIdentifier("key to identify message") {
  ..
}

Using subscript

if let message = appGroup["key to identify message"] as? String { .. }

Todo

• Tests
• WatchKit (WatchConnectivity/WCSession...)
• Carthage: let me know if carthage work and I will add the shell.io badges and installation instruction

Contribute

I am more than happy to accept external contributions to the project in the form of feedback, bug reports and even better pull requests.

Implement WatchKit features and I will add you to the project (I have no need and time to do it now)
