I am using Ray Wenderlich's Storyboard tutorial part 1 to learn how to use storyboards, and I'm doing it in Swift. So I'm transferring the following code, which is located in the AppDelegate.swift file, from
UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
UINavigationController *navigationController = [tabBarController viewControllers][0];
PlayersViewController *playersViewController = [navigationController viewControllers][0];
playersViewController.players = _players;
to
let tabBarController : UITabBarController = self.window?.rootViewController as UITabBarController
let navBarController = tabBarController.viewControllers[0] as UINavigationController
let playersController = navBarController.viewControllers[0]
playersController.players = self.players
However, the latter section of code throws a compiler error because when I declare playersController I'm not downcasting the AnyObject that is returned by navBarController.viewControllers[0] to my custom PlayersTableViewController class. So I do that with the following code
let playersController = navBarController.viewControllers[0] as PlayersTableViewController
But this causes the SourceKitService Xcode 6 bug to be appear, and I lose all syntax highlighting.
So I'm left with either continuing with no syntax highlighting, or not continue at all because playersController needs to be recognized as a PlayersTableViewController in order to access the players property. I've narrowed it down to that downcast operation that causes Xcode to bug out, does anyone have any solutions to this problem?
EDIT: I tried to go ahead without syntax coloring, write the necessary code, and then compile it, but it threw the following messy compiler error.
