SwiftUI Facebook SDK : App ID not found. Add a string value with your app ID for the key FacebookAppID to the Info.plist

Question

I have added the the correct Facebook sdk values into info.plist as the Quick Start guide shows & added the SDK using the package manager, but I still get this error

Thread 1: App ID not found. Add a string value with your app ID for the key FacebookAppID to the Info.plist or call [FBSDKSettings setAppID:].

The app Id is 100% correct & it is in my info.plist. If I set the name & app Id in my app delegate I just get this error instead:

Thread 1: fbappid is not registered as a URL scheme. Please add it in your Info.plist

It seems as though the Facebook SDK can't find any values in my info.plist?

<key>CFBundleURLTypes</key>

            <key>CFBundleURLSchemes</key>

Answer 1

Add this in new file

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        // Initialize Facebook SDK
        FBSDKCoreKit.ApplicationDelegate.shared.application(
            application,
            didFinishLaunchingWithOptions: launchOptions
        )
        return true
    }
}

Tested in Xcode 12.5

make an AppDelegate.swift and add this code below.

import SwiftUI
import FacebookCore

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication,
                     didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
    
    func application(_ app: UIApplication,
                     open url: URL,
                     options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        return ApplicationDelegate.shared.application(app, open: url, options: options)
    }
}

next in your @main App file add this line

 @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate

I had the same issue because I forgot to add fb as prefix of App Id in URL Schemes.

Make sure that you've added like this fb{app_id} into url schemes like image below.
