【问题描述】：
将 Xcode 更新到版本 6.1 (6A1052d) 后，应用程序在 iPhone 5s (iOS8.1) 上不断崩溃。然而，一切都在 XCode 上运行得很好。手机永不越狱
Dyld Error Message:

Dyld Version: 353.5
以下部分发生错误（AppDelegate.swift 文件）
import UIKit
import Foundation
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UIAlertViewDelegate {
var window: UIWindow?
var firebaseURL: NSString! = "https://our-url.firebaseio.com" // Breakpoint: EXC_BREAKPOINT (code=EXC_ARM_BREAKPOINT, subcode=0xe7ffdefe)
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
self.window!.makeKeyAndVisible()
return true
}
断点位于“var firebaseURL”行。我尝试将其删除，但它会在分配给变量的每个字符串文字上中断。我尝试将变量设为可选并展开，但它不起作用，同时尝试了 String 和 NSString。
以下是更详细的崩溃日志版本
