Answer 1

I followed Suraj Pathak with Xcode 9.4.1 and Swift 4.2

1. Add to AppDelegate didFinishLaunchingWithOptions

   SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
   

2. Add to AppDelegate delegate function

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

3. Allow Keychain in Capabilities.
