Installation

To include PushNotifications in your package, add the following to your Package.swift file.

// swift-tools-version:4.0
import PackageDescription

let package = Package(
    name: "YourProjectName",
    dependencies: [
        ...
        .package(url: "git@github.com:pusher/push-notifications-server-swift.git", from: "1.0.3",
    ],
    targets: [
      .target(name: "YourProjectName", dependencies: ["PushNotifications", ... ])
    ]
)

Use import PushNotifications to access the APIs.

Usage

Migrating from 1.x to 2.x

The 2.0 release contains several improvements, however there are a few breaking API changes if you are upgrading from a 1.x release:

Migration notes

1. The SDK replaces its own Result implementation the Result type included in Swift 5.0. The API changes subtly when inspecting the result value (e.g. when using a switch statement):
   • .value(let anObject): becomes .success(let anObject):
   • .error(let anObject): becomes .failure(let anObject):
2. Errors returned by the SDK in a Result are now specifically instances of PushNotificationsError rather than just Error.
3. PushNotificationsError has some changes:
   • New error cases have been added covering the error conditions that were previously reported using the .error(String) (which has been removed). Testing against SDK errors in your own server app is now straightforward and more robust as no String equality checks are required.
   • It now conforms to LocalizedError. A human-readable description of an error can be accessed using the localizedDescription property on the error.
4. The publish(_:_:completion:) method has been removed (this was deprecated in a previous release). The publishToInterests(_:_:completion:) method can be used instead.

Code examples

// Pusher Beams Instance Id.
let instanceId = "c7c52433-8c65-43e6-9ef2-922d9ed9e196"
// Pusher Beams Secret Key.
let secretKey = "39817C9BCBF7F053CB151343D54EE75"

// PushNotifications instance.
let pushNotifications = PushNotifications(instanceId: instanceId, secretKey: secretKey)

// Interests array.
let interests = ["pizza", "donuts"]
// Publish request: APNs, FCM.
let publishRequest = [
  "apns": [
    "aps": [
      "alert": "Hello"
    ]
  ],
  "fcm": [
    "notification": [
      "title": "Hello",
      "body":  "Hello, world",
    ]
  ]
]

// Publish To Interests
pushNotifications.publishToInterests(interests, publishRequest, completion: { result in
    switch result {
    case .success(let publishId):
        print("\(publishId)")
    case .failure(let error):
        print("\(error)")
    }
})

// Publish To Users
pushNotifications.publishToUsers(["jonathan", "jordan", "luís", "luka", "mina"], publishRequest, completion: { result in
    switch result {
    case .success(let publishId):
        print("\(publishId)")
    case .failure(let error):
        print("\(error)")
    }
})

// Authenticate User
pushNotifications.generateToken("Elmo", completion: { result in
    switch result {
    case .success(let jwtToken):
        // 'jwtToken' is a Dictionary<String, String>
        // Example: ["token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJhYWEiLCJleHAiOjE"]
        print("\(jwtToken)")
    case .failure(let error):
        print("\(error)")
    }
})

// Delete User
pushNotifications.deleteUser("Elmo", completion: { result in
    switch result {
    case .success:
        print("User deleted 👌")
    case .failure(let error):
        print("\(error)")
    }
})
