Setup Guide

Important

Version 3.0.1 integration

The SDK now provides three simple ways to integrate push notifications:

  1. SwiftUI apps without AppDelegate - using @UIApplicationDelegateAdaptor
  2. UIKit apps with inheritance - extend PPGAppDelegate
  3. UIKit apps with existing AppDelegate - use helper methods

Key improvements:

  • Simplified initialization with PPG.initializeNotifications
  • Automatic notification delegate handling
  • Built-in support for all notification callbacks

SPM support

Version 2.1.0 and above support SPM. Cocoapods is no longer supported from version 2.1.0.

Requirements

  • Add AppGroups capability to your project
  • Create Notification Service Extension (see section below)

[ Create certificate and upload it ]

Tutorial: https://docs.pushpushgo.company/application/providers/mobile-push/apns

Install framework

Choose one of options:

  • SPM (recommended)
  • Direct download
  • Cocoapods (deprecated from v2.1.0)

Integration

Note

While the previous integration method (manually implementing all AppDelegate notification methods) will continue to work, we recommend switching to one of the new integration methods below. The new methods provide automatic notification handling and significantly reduce the amount of boilerplate code needed (SwiftUI).

The SDK supports three integration methods:

1. SwiftUI Apps (without AppDelegate)

For SwiftUI apps that don't have a custom AppDelegate:

import SwiftUI
import PPG_framework

@main
struct YourApp: App {
    @UIApplicationDelegateAdaptor(PPGAppDelegate.self) var appDelegate
    
    init() {
        // Initialize PPG
        PPG.initializeNotifications(
            projectId: "YOUR_PROJECT_ID",
            apiToken: "YOUR_API_TOKEN",
            appGroupId: "YOUR_APP_GROUP_ID"
        )
    }
    
    var body: some Scene {
        WindowGroup {
            ContentView()
                .onAppear {
                    // Register for notifications when the view appears
                    PPG.registerForNotifications(application: UIApplication.shared) { result in
                        switch result {
                        case .success:
                            print("Successfully registered for notifications")
                        case .error(let message):
                            print("Failed to register for notifications: \(message)")
                        }
                    }
                }
        }
    }
}

2. UIKit Apps (Inheriting from PPGAppDelegate)

For UIKit apps that want to inherit push notification handling:

import UIKit
import PPG_framework

@main
class AppDelegate: PPGAppDelegate {
    override func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        // First call super to setup PPG delegate
        let result = super.application(application, didFinishLaunchingWithOptions: launchOptions)
        
        // Initialize PPG
        PPG.initializeNotifications(
            projectId: "YOUR_PROJECT_ID",
            apiToken: "YOUR_API_TOKEN",
            appGroupId: "YOUR_APP_GROUP_ID"
        )
        
        // Register for notifications
        PPG.registerForNotifications(application: application) { result in
            switch result {
            case .success:
                print("Successfully registered for notifications")
            case .error(let message):
                print("Failed to register for notifications: \(message)")
            }
        }
        
        // Your additional setup code
        return result
    }
}

3. UIKit Apps (with Existing AppDelegate using helper functions)

For UIKit apps that already have an AppDelegate:

import UIKit
import PPG_framework

@main
class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        // Initialize PPG
        PPG.initializeNotifications(
            projectId: "YOUR_PROJECT_ID",
            apiToken: "YOUR_API_TOKEN",
            appGroupId: "YOUR_APP_GROUP_ID"
        )
        
        // Setup PPG notification delegate
        PPGUserNotificationCenterDelegateSetUp()
        
        // Register for notifications
        PPG.registerForNotifications(application: application) { result in
            switch result {
            case .success:
                print("Successfully registered for notifications")
            case .error(let message):
                print("Failed to register for notifications: \(message)")
            }
        }
        
        return true
    }
    
    func applicationDidBecomeActive(_ application: UIApplication) {
        PPGapplicationDidBecomeActive()
    }
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        PPGdidRegisterForRemoteNotificationsWithDeviceToken(deviceToken)
    }
    
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        PPGdidReceiveRemoteNotification(userInfo, completionHandler: completionHandler)
    }
}

Migration from older versions

Cocoapods -> SPM

  1. If PPG ios-sdk was the only library installed by Pods, run pod deintegrate to remove any Pods-related files. If you are using Pods for any other dependencies, then remove PPG_framework references manually. Also detach it from project and NSE targets.
  2. Add library using SPM. Xcode -> File -> Add Package Dependency. Provide github url and choose your project target.
  3. Manually add library to NotificationServiceExtension target.
  4. Clean and rebuild the project.
  5. If you face any problems with derived data try running rm -rf ~Library/Developer/Xcode/DerivedData/* in your project directory. Then restart Xcode and clean and rebuild project.

Add required capabilities

  1. Click on top item in your project hierarchy.
  2. Select your project on target list.
  3. Select Signing & Capabilities.
  4. You can add capability by clicking on + Capability button that is placed under Signing & Capabilities button.
  5. Add Background Modes capability unless it is already on your capability list. Then select Remote notifications.
  6. Add Push notifications capability unless it is already on your capability list.
  7. Add App Groups. You can use your default app group ID or add new one.
  8. Make sure that your Provisioning Profile has required capabilities. If you didn't add them while creating Provisioning Profile for your app you should go to your Apple Developer Center to add them. Then refresh your profile in Xcode project.

How to add new group to your provisioning profile?

Go to Apple developers and navigate to Certificates, Identifiers & Profiles. Then go to Identifiers and in the right corner change App IDs to AppGroups. You can add new group here.

Now you can go back to Identifiers, choose your app identifier and add AppGroup capability. Remember to check your new group.

Create Notification Service Extension

  1. Open your Xcode project
  2. Go to File -> New -> Target.
  3. Select Notification Service Extension.
  4. Choose a suitable name for it (for example PPGNotificationServiceExtension).
  5. Open NotificationService.swift file.
  6. Change didReceive function to: (use dispatch_group here to make sure that extension returns only when delivery event is sent and notification content is updated)
  7. Click on top item in your project hierarchy and select your NotificationExtension on target list
  8. Similarly to your project, add App Group capability to your NotificationExtension and check group you want to use.
  9. Also add PPG_framework to NotificationServiceExtension target (General tab) if you haven't done that yet.
  10. In your NotificationService extension, in didReceive function set your app group ID.
override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
    self.contentHandler = contentHandler
    self.bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

    guard let content = bestAttemptContent else { return }

    // Wait for delivery event result & image fetch before returning from extension
    let group = DispatchGroup()
    group.enter()
    group.enter()

    // Dynamically set app group ID for your app
    SharedData.shared.appGroupId = "YOUR APP GROUP ID"

    PPG.notificationDelivered(notificationRequest: request) { _ in
        group.leave()
    }

    DispatchQueue.global().async { [weak self] in
        self?.bestAttemptContent = PPG.modifyNotification(content)
        group.leave()
    }

    group.notify(queue: .main) {
        contentHandler(self.bestAttemptContent ?? content)
    }
}

Usage guide

Create and send Beacon

let beacon = Beacon()
beacon.addSelector("Test_Selector", "0")

// Methods with strategy and ttl support
// For append tag in concrete category (with ttl, default = 0)
beacon.appendTag("mytag", "mycategory")
beacon.appendTag("mytag", "mycategory", 3600)

// For rewrite tag in concrete category (with ttl, default = 0)
beacon.rewriteTag("mytag", "mycategory")
beacon.rewriteTag("mytag", "mycategory", 3600)

// For delete tag in concrete category (with ttl, default = 0)
beacon.deleteTag("mytag", "mycategory");

// Legacy methods (not supports strategy append/rewrite and ttl)
beacon.addTag("new_tag", "new_tag_label")
beacon.addTagToDelete(BeaconTag(tag: "my_old_tag", label: "my_old_tag_label"))

beacon.send() { result in }

Unsubscribe user

PPG.unsubscribeUser { result in ... }

Interactive Notifications

The SDK supports interactive notifications with action buttons. Actions are configured through the notification payload and automatically managed by the SDK:

  • Buttons are created dynamically based on the payload
  • Duplicate button titles are handled automatically
  • Categories expire after 7 days
  • URLs can be associated with specific buttons

Button identifiers:

  • button_1: First action button
  • button_2: Second action button

Supported button options:

  • foreground: Opens the app
  • destructive: Red button style
  • authenticationRequired: Requires device unlock

The SDK automatically manages:

  • Category creation and registration
  • Button title uniqueness
  • Action handling and URL redirection
  • Event tracking for button clicks
