-canOpenURL: failed for URL: “fbauth2:/” - error: “The operation couldn’t be completed. (OSStatus error -10814.)” SWIFT 5 FBDSKCoreKit 5

Question

I have seen a few similar threads and possible solutions, but they are all 1+ yrs old and I dont think relevant to updated versions.

I'm using swift 5, and FirebaseUI 8.4.2 which is compatible with FBSDKLoginKit (~> 5.0). (also using ios 12.2)

My info.plist includes fbauth2 and I've included App Transport Security Settings --> allow arbitrary loads = YES which was added for ios 9.

In my appDelegate I have

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    FirebaseApp.configure()
    let db = Firestore.firestore()

    //facebook login
    //ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

    FBSDKCoreKit.ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

  return true
   }

  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
      let handled = ApplicationDelegate.shared.application(app, open: url, options: options)

      return handled
  }

Feel like ive exhausted all solutions in other threads so if anyone has an updated workaround pls could you post below.

Did you add the correct url scheme for fb in URL Types section in XCode project -> Info tab.

Xcode project Info tab

You can verify that by checking url.scheme in application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) .
