Good afternoon, 
Looking for experts in Xcode for trailhead solution. 
https://trailhead.salesforce.com/content/learn/projects/mini-hack-mobile-sdk-ios/query-data-with-asynchronous-logic doing this part and keep getting this error, but when I build my project, everything looks correct - Screenshot attached from the simulator. 
We couldn't verify that LoadView() was configured. In Xcode, please add the LoadView() method to your AccountSceneController.swift file. When the app is ready, build and run it, and log in with your corresponding playground credentials.
