Sorry for any confusion caused by my comment in chat; I was conflating
ApplicationState with just the bundle set-up. This is overkill for now.

+  self.applicationState.application = application;
+  [self configureApplicationState];
+
+  [self.applicationState launchWithOptions:launchOptions];
+
   return YES;
 }

 // Creates model data to display in the view controller.
 - (NSArray<showcase::ModelRow*>*)rowsToDisplay {
   NSArray<showcase::ModelRow*>* rows = [ShowcaseModel model];
   NSSortDescriptor* sortDescriptor =
       [NSSortDescriptor sortDescriptorWithKey:showcase::kClassForDisplayKey
                                     ascending:YES];
   return [rows sortedArrayUsingDescriptors:@[ sortDescriptor ]];
 }
 
+// Configures the application state for application launch by setting the launch
+// steps.
+// Future architecture/refactoring note: configuring the application state in
+// this way is outside the scope of responsibility of the object as defined in
+// the header file. The correct solution is probably a helper object that can
+// perform all of the configuration necessary, and that can be adjusted as
+// needed.
