我的swift应用程序在运行时失败了。我该如何解决这个问题？
我已经检查过，avgTime_text定义明确。
我不知道如何在xcode中读取堆栈跟踪，有人可以帮助一点指导吗？

此处是代码失败的地方：window?.makeKeyAndVisible()
AppDeligate
func launchStoryboard(storyboard: Storyboard) {
window = UIWindow(frame: UIScreen.mainScreen().bounds)
UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: .Slide)
let storyboard = UIStoryboard(name: storyboard.rawValue, bundle: nil)
let controller = storyboard.instantiateInitialViewController()!
if (controller is InlineMainViewController ){
mainViewController = controller as! InlineMainViewController
}
window?.rootViewController = controller
window?.makeKeyAndVisible()
}

即使这是一篇旧帖子，也请在Xcode中查看用户定义的运行时属性。您可能已经在此处声明了默认属性，删除它应该可以解决您的问题。
