Installation
To install APNSwift
, just add the package as a dependency in your Package.swift.
dependencies: [
.package(url: "https://github.com/swift-server-community/APNSwift.git", from: "6.0.0"),
]
Getting Started
APNSwift aims to provide semantically correct structures to sending push notifications. You first need to setup a APNSClient
. To do that youll need to know your authentication method
let client = APNSClient(
configuration: .init(
authenticationMethod: .jwt(
privateKey: try .init(pemRepresentation: privateKey),
keyIdentifier: keyIdentifier,
teamIdentifier: teamIdentifier
),
environment: .development
),
eventLoopGroupProvider: .createNew,
responseDecoder: JSONDecoder(),
requestEncoder: JSONEncoder()
)
// Shutdown the client when done
try await client.shutdown()
Sending a simple notification
All notifications require a payload, but that payload can be empty. Payload just needs to conform to Encodable
struct Payload: Codable {}
try await client.sendAlertNotification(
.init(
alert: .init(
title: .raw("Simple Alert"),
subtitle: .raw("Subtitle"),
body: .raw("Body"),
launchImage: nil
),
expiration: .immediately,
priority: .immediately,
topic: "com.app.bundle",
payload: Payload()
),
deviceToken: "device-token"
)
Sending Live Activity Update / End
It requires sending ContentState
matching with the live activity configuration to successfully update activity state. ContentState
needs to conform to Encodable
and Sendable
.
try await client.sendLiveActivityNotification(
.init(
expiration: .immediately,
priority: .immediately,
appID: "com.app.bundle",
contentState: ContentState,
event: .update,
timestamp: Int(Date().timeIntervalSince1970)
),
deviceToken: activityPushToken
)
try await client.sendLiveActivityNotification(
.init(
expiration: .immediately,
priority: .immediately,
appID: "com.app.bundle",
contentState: ContentState,
event: .end,
timestamp: Int(Date().timeIntervalSince1970),
dismissalDate: .immediately // Optional to alter default behaviour
),
deviceToken: activityPushToken
)
Authentication
APNSwift
provides two authentication methods. jwt
, and TLS
.
jwt
is preferred and recommend by Apple
These can be configured when created your APNSClientConfiguration
Notes: jwt
requires an encrypted version of your .p8 file from Apple which comes in a pem
format. If you're having trouble with your key being invalid please confirm it is a PEM file
openssl pkcs8 -nocrypt -in /path/to/my/key.p8 -out ~/Downloads/key.pem
Logging
By default APNSwift has a no-op logger which will not log anything. However if you pass a logger in, you will see logs.
There are currently two kinds of loggers.
Background Activity Logger
This logger can be passed into the APNSClient
and will log background things like connection pooling, auth token refreshes, etc.
Notification Send Logger
This logger can be passed into any of the send:
methods and will log everything related to a single send request.
Server Example
Take a look at Program.swift
iOS Examples
For an iOS example, open the example project within this repo.
Once inside configure your App Bundle ID and assign your development team. Build and run the ExampleApp to iOS Simulator, grab your device token, and plug it in to server example above. Background the app and run Program.swift
