I’m having trouble building the starter project. It has multiple errors. I’ve tried fixing some, but a few are too difficult to figure out.

here is an up to date version of the SKNode extension:

extension SKNode {
    class func unarchiveFromFile(file : NSString) -> SKNode? {
        
        let path = NSBundle.mainBundle().pathForResource(file as String, ofType: "sks")
        
        let sceneData = NSData(contentsOfURL: NSURL(fileURLWithPath: path!))!
        
        
        let archiver = NSKeyedUnarchiver(forReadingWithData: sceneData)
        
        archiver.setClass(self.classForKeyedUnarchiver(), forClassName: "SKScene")
        let scene = archiver.decodeObjectForKey(NSKeyedArchiveRootObjectKey) as! GameScene
        archiver.finishDecoding()
        return scene
    }
}

Hello, this file has a whole mess of errors. I am using swift 2.0. Can somebody help me correct these errors. They are to difficult for me to figure out. I have been trying but no luck.

Same here, I hope that they always keep their code tutorials up to date when Swift versions come out.

Hi, I have resolved 3 errors but still have 2 more, but here is the solution for the 3 errors maybe will work with you.

in AppDelegate.swift
change the current func didFinishLaunchingWithOptions with :

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Override point for customization after application launch. return true }

and in GameViewController.swift change the extension SKNode with :

`extension SKNode {
    class func unarchiveFromFile(file : NSString) -> SKNode? {
        
        let path = NSBundle.mainBundle().pathForResource(file as String, ofType: "sks")
        
        let sceneData = NSData(contentsOfURL: NSURL(fileURLWithPath: path!))!
        
        
        let archiver = NSKeyedUnarchiver(forReadingWithData: sceneData)
        
        archiver.setClass(self.classForKeyedUnarchiver(), forClassName: "SKScene")
        let scene = archiver.decodeObjectForKey(NSKeyedArchiveRootObjectKey) as! GameScene
        archiver.finishDecoding()
        return scene
    }
}`

and in the same swift file go to supportedInterfaceOrientations function at the bottom and change the return values only with :

return UIInterfaceOrientationMask.AllButUpsideDown

and in the second return change it to :

return UIInterfaceOrientationMask.All
