GM release of Xcode 6 compile

I just downloaded the GM release of Xcode 6 and it won\'t compile with this error:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault         


        

Answer 1

To add my case here. I got the described error whenever I mark the closure with [unowned self], but never reference the self in the closure itself.

For example:

        request.startWithSuccess({ [unowned self] (req: CBRequest!, object: AnyObject!) -> Void in

            if let result = object["result"] as? [NSObject: AnyObject]
            {
                popup.type = result["email"] == nil ? AuthPopupType.Signup : AuthPopupType.Login
            }
            else
            {
                println("WARNING: Malformed response for kCBCheckUniquenesPath request.")
            }

            }, failure: { (req: CBRequest!, err: NSError!) -> Void in

                println("ERROR: Failure response for kCBCheckUniquenesPath request.")
        })
