Installation

Swift Package Manager

import PackageDescription
let package = Package(
    dependencies: [
        .package(url: "https://github.com/ibm-bluemix-mobile-services/bluemix-pushnotifications-swift-sdk.git", .upToNextMajor(from: "1.6.0"))
	]
)

Build on Linux

sudo apt-get update // not required on Mac
swift build -Xcc -fblocks -Xlinker -rpath -Xlinker $(pwd)/.build/debug/

Usage

Simple notification

Complete the following steps:

1. Import the IBMPushNotifications framework.

   import IBMPushNotifications
   

Note: For Syndicated use the overrideServerHost param of PushNotifications before initliazong the PushNotifications . Eg: PushNotifications.overrideServerHost = "https://syndicated.region.net"

2. Initialize with details about your IBM Cloud Push Notifications service.

• Initialize with ApiKey

  
  //Initialize PushNotifications
  let myPushNotifications = PushNotifications(pushApiKey:"your-push-service-apiKey", pushAppGuid: "your-push-service-app_guid", pushRegion: PushNotifications.Region.US_SOUTH)
  
  // GET AUTH TOKEN
  myPushNotifications?.getAuthToken(completionHandler: { (hasToken, tokenString) in
  	if hasToken! {
  		// Send push notifications
  	}
  })
  

• Initialize with AppSecret

  let myPushNotifications = PushNotifications(pushRegion: PushNotifications.Region.US_SOUTH, pushAppGuid: "your-push-service-guid", pushAppSecret: "your-push-service-appSecret")
  

3. Create a simple push notification that will broadcast to all devices.

   let messageExample = Notification.Message(alert: "Testing IBMPushNotifications")
   let notificationExample = Notification(message: messageExample)
   

4. Send the Push notification using the method:

   myPushNotifications.send(notification: notificationExample) { (data, status, error) in
     if error != nil {
       print("Failed to send push notification. Error: \(error!)")
     }
   }
   

Note: If you are using the APIKEY for Initialisation kindly call getAuthToken() , before sending any notification. This will add an Authorization header for the request.

To create a more selective push notification with specified settings that is only sent to certain devices either by deviceIds or userIds or by device platforms or based on tag-subscriptions, or to set GCM and APNs features - there are optional parameters that you can use in the corresponding initializers.

Send Bulk push notifications

To send the bulk push notifications of the following,

myPushNotifications.sendBulk(notification: [notificationExample,notificationExample1,notificationExample2]) { (data, status, error) in
	if error != nil {
		print("Failed to send push notification. Error: \(error!)")
	}
}

Notification options

Target

In Target, you pass the following values:

• deviceIds - Array of device IDs.

• userIds - Array of user IDs.

• platforms - Array of platforms.

• tagNames - Array of tag names.

  let targetExample = Notification.Target(deviceIds: ["device1","device2"],
           userIds: ["userId1", "userId2"],
           platforms: [TargetPlatform.Apple,TargetPlatform.Google,TargetPlatform.ChromeExtApp,
  TargetPlatform.WebChrome,TargetPlatform.webFirefox,TargetPlatform.WebSafari], tagNames: ["tag1", "tag2"])
  

Note: Do not use userIds, tagNames, platforms and deviceIds together.
