Note: Remember to format your code for readability:

let loginManager = LoginManager()
        loginManager.logIn(permissions: [.publicProfile, .email], viewController: self, completion: { loginResult in
            switch loginResult {
            case .failed(let error):
                print("\(error)")
            case .cancelled:
                print("cancelled")
            case .success(let grantedPermissions, let declinedPermissions, let accessToken):
                print("\(grantedPermissions) \(declinedPermissions)")
            }
})

Yes, I solved updating to the new pods

I encountered the same problem

But updating to the latest version is still not resolved

Installing FacebookCore (0.9.0)
Installing FacebookLogin (0.9.0)
Xcode (11.2.1)

If you're using Scene pattern, you have to add this code in SceneDelegate.swift

func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
        guard let url = URLContexts.first?.url else {
            return
        }
        let _ = ApplicationDelegate.shared.application(
            UIApplication.shared,
            open: url,
            sourceApplication: nil,
            annotation: [UIApplication.OpenURLOptionsKey.annotation])
 }

Importing FBSDKCoreKit as well
