Firebase causing "Thread 1: signal SIGABRT" - ios

Question

I started a blank Xcode project and all I did was add the Firebase framework via Cocoapods and import in the Appdelegate and viewcontroller. When I add FIRApp.configure() to didFinishLoadingWithOptions I get that error. If I remove that line but still have the framework imported it runs with no errors. This happens on a blank project with nothing in the storyboard nor viewcontroller.swift.
In the console it says libc++abi.dylib: terminating with uncaught exception of type NSException
(11db)
Xcode 8.2, swift 3
import UIKit
import Firebase
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FIRApp.configure()
return true
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
}
Podfile
# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
target 'dur2' do
# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
# Pods for dur2
pod 'Firebase/Core'
pod 'Firebase/AdMob'
pod 'Firebase/Messaging'
pod 'Firebase/Database'

Answer 1

Let's try a test.
Create a new project following the instructions on the Firebase website, ensuring you add the GoogleService-Info.plist to your project.
At the step where you create a pod file, make sure you are in your projects folder and use this text:
# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
target 'your-project-name' do
# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
# Pods for Firesearch
pod ‘Firebase/Core’
end
and put your project name in place of your-project-name
Save the file and then do a
pod install
Then open the project-name.xcworkspace and build it.

Answer 2

Worked for Xcode 9
If none of solutions worked for you try this:
Close Xcode
In Finder:
Remove .xcworkspace file
Remove Podfile.lock file
Remove Pods folder
In Terminal (in project folder): pod install
Make sure that GoogleService-Info.plist is added to your target and generated for your BUNDLE_ID.
For unknown reasons when you use both "Firebase/Admob" and "Firebase/Core" pods Xcode can mess up the workspace and produce a bad build that will crash at runtime if you try to call FirebaseApp.configure() or GADMobileAds.configure(withApplicationID: "APP_ID")

Answer 3

If you haven't yet,
Go to your project in firebase and download the google.plist file and add it to your project and run.

Answer 4

I had the same problem and I solved it by using another gmail account. Create a new project on firebase then create a data base and add your ios app to the firebase database (Make sure that GoogleService-Info.plist is added to your target and generated for your BUNDLE_ID.)

Answer 5

I've been pulling my hair for 2 days...
here is what I found
make sure you have the right GoogleService-info.plist file
enable the .plist file.
point the file to your target app
plist target to your app

Answer 6

Instead of copying GoogleService-Info.plist to your project, just drag and drop GoogleService-Info.plist to ios/appName, then check the copy if needed option.

Answer 7

For Swift 4 and Xcode 10:
Delete the XC workspace, podfile.lock, podfile and the pod folder. Then re-do the pod install and start with your new XC workspace.
