Really someone initializes FB SDK as recommended in doc at app start? I immediately knew that it is not good idea. I do it after user request sign in via facebook only...

MyLoginManager.swift

import FBSDKLoginKit;
import Foundation;
import GoogleSignIn;

class MyLoginManager: NSObject, LoginButtonDelegate {

...

    public func initAppleLogin() {
        ...
    }

    public func initGoogleLogin() {
        ...
    }

    public func initFacebookLogin() {
        // (!!!) Init FB SDK now, not at app start because of performance reason
        FBSDKCoreKit.ApplicationDelegate.shared.application(UIApplication.shared, didFinishLaunchingWithOptions: nil);

        // Logout before sign in to avoid dialog that user already logged in
        let facebookLoginManager = FBSDKLoginKit.LoginManager();
        facebookLoginManager.logOut();

        // Fake login button
        let loginButton = FBLoginButton(frame: .zero);
        loginButton.permissions = ["public_profile", "email"];
        loginButton.delegate = self;
        loginButton.isHidden = true;
        loginButton.sendActions(for: .touchUpInside);
    }

    func loginButton(_ loginButton: FBLoginButton, didCompleteWith result: FBSDKLoginKit.LoginManagerLoginResult?, error: Error?) -> Void {
        ...
    }

    func loginButtonDidLogOut(_ loginButton: FBLoginButton) -> Void {
        ...
    }

    ...

}

Btw consider disabling FB useless bloatware... Info.plist

<key>FacebookAdvertiserIDCollectionEnabled</key>
<false/>
<key>FacebookAutoLogAppEventsEnabled</key>
<false/>
