Get Started - Facebook SDK for iOS

The Facebook SDK for iOS is the easiest way to integrate your iOS app with Facebook. It enables:

Facebook Analytics - Understand how people are using your product.
Facebook Login - Authenticate people with their Facebook credentials.
Share and Send dialogs - Enable sharing content from your app to Facebook.
App Events - Log events in your application.
Graph API - Read and write to Graph API.

Before You Start

This procedure assumes you are using the latest version of iOS and xCode. Learn more at the Apple Developer.

You will need:

A Facebook for Developers Account If you need one, click this button and follow the steps.

Create a Facebook for Developers Account

An App ID for Your App click this button and follow the steps to register your app and get an App ID

Get an App ID for your app

Step 1: Set Up Your Development Environment

In Xcode, click File > Swift Packages > Add Package Dependency.
In the dialog that appears, enter the repository URL: https://github.com/facebook/facebook-ios-sdk.
In Version, select Up to Next Major and the default option.
Complete the prompts to select the libraries you want to use in your project.

Step 2: Configure Your Project

Configure the information property list file (info.plist) with an XML snippet that contains data about your app.

Right-click info.plist, and choose Open As Source Code.

Copy and paste the following XML snippet into the body of your file ( <dict>...</dict>).

<key>CFBundleURLTypes</key>
<array>
  <dict>
  <key>CFBundleURLSchemes</key>
  <array>
    <string>fb[APP_ID]</string>
  </array>
  </dict>
</array>
<key>FacebookAppID</key>
<string>[APP_ID]</string>
<key>FacebookDisplayName</key>
<string>[APP_NAME]</string>

In <array><string> in the key [CFBundleURLSchemes], replace [APP_ID] with your App ID.
In <string> in the key FacebookAppID, replace [APP_ID] with your App ID.
In <string> in the key FacebookDisplayName, replace [APP_NAME] with the name of your app.

To use any of the Facebook dialogs (e.g., Login, Share, App Invites, etc.) that can perform an app switch to Facebook apps, your application's info.plist also needs to include: <dict>...</dict>).

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>fbapi</string>
  <string>fbapi20130214</string>
  <string>fbapi20130410</string>
  <string>fbapi20130702</string>
  <string>fbapi20131010</string>
  <string>fbapi20131219</string>
  <string>fbapi20140410</string>
  <string>fbapi20140116</string>
  <string>fbapi20150313</string>
  <string>fbapi20150629</string>
  <string>fbapi20160328</string>
  <string>fbauth</string>
  <string>fb-messenger-share-api</string>
  <string>fbauth2</string>
  <string>fbshareextension</string>
</array>

Step 3: Connect the App Delegate

Replace the code in AppDelegate.swift with the following code. This code initializes the SDK when your app launches, and allows the SDK handle results from the native Facebook app when you perform a Login or Share action:

//  AppDelegate.swift

import UIKit
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
          
        ApplicationDelegate.shared.application(
            application,
            didFinishLaunchingWithOptions: launchOptions
        )

        return true
    }
          
    func application(
        _ app: UIApplication,
        open url: URL,
        options: [UIApplication.OpenURLOptionsKey : Any] = [:]
    ) -> Bool {

        ApplicationDelegate.shared.application(
            app,
            open: url,
            sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
            annotation: options[UIApplication.OpenURLOptionsKey.annotation]
        )

    }  

}

If you are using iOS 13 or above please add the following method to your SceneDelegate:

//  SceneDelegate.swift

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    guard let url = URLContexts.first?.url else {
        return
    }

    ApplicationDelegate.shared.application(
        UIApplication.shared,
        open: url,
        sourceApplication: nil,
        annotation: [UIApplication.OpenURLOptionsKey.annotation]
    )
}

Step 4: Build and Then Run Your Project in the Simulator

In Xcode, select an iOS simulator and click Run. Xcode builds your project and then launches the most recent version of your app running in Simulator.

Step 5: See the Results in Events Manager

The Events Manager displays the events you send to Facebook Analytics. If this is the first time you launched your app with this code, you may have to wait at least 20 minutes before your events appear.

Note: Events may take up to 20 minutes to appear in the dashboard.
