如何更正Xcode工作区中的调试问题

Question

每次我在Xcode工作区中构建应用程序以连接Firebase服务器时，我都会遇到线程1信号sigabrt 。为什么这会不断出现，我可以获得一些帮助吗？

   0x112601804 : callq  0x112601869               ; _UIApplicationMainPreparations
    0x112601809 : movq   0xceb190(%rip), %rdi      ; UIApp
    0x112601810 : movq   0xc5f841(%rip), %rsi      ; "_run"
    0x112601817 : callq  *0x892c93(%rip)           ; (void *)0x000000010e7c4d80: objc_msgSend
    0x11260181d : movq   0x892c94(%rip), %rbx      ; (void *)0x000000010e7c2010: objc_release (thread 1 signal sigabrt)
    0x112601824 : movq   %r15, %rdi 

import UIKit
import Firebase

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { FirebaseApp.configure()
        // Override point for customization after application launch.
        return true
    }

    func applicationWillResignActive(_ application: UIApplication) {

Podfile：

 # platform :ios, '9.3'

target 'TV' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!
pod 'Firebase/Core'
  # Pods for TV

这是暗示集成Firebase的说明，但调试问题不断出现。我该如何解决这个问题？
