Firebase app not being configured - ios

Question

This randomly started happening and I cannot get passed it. My app crashes on launch with this in the debug area.
2016-10-29 14:31:57.606 gigMe[2285:73317] Firebase automatic screen reporting is enabled. Call +[FIRAnalytics setScreenName:setScreenClass:] to set the screen name or override the default screen class name. To disable automatic screen reporting, set the flag FirebaseAutomaticScreenReportingEnabled to NO in the Info.plist
2016-10-29 14:31:57.783 gigMe[2285] [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add [FIRApp configure] to your application initialization. Read more: gives google address that i cant post on here
2016-10-29 14:31:57.911 gigMe[2285:73317] * Terminating app due to uncaught exception 'FIRAppNotConfigured', reason: 'Failed to get default FIRDatabase instance. Must call FIRApp.configure() before using FIRDatabase.' * First throw call stack:
I really dont understand this at all because i havent messed with anything that has to do with the database and this is my didFinishLaunchingWithOptions method:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
print("wtf")
FIRApp.configure()
return true
}
im not getting anything printed in the debugger either. anyone know what is going on?

Answer 1

This is not FIRApp.configure() error. You might be declaring a global variable with some class function in any of your class, like
class viewCon : UIViewController{
let ref = FIRDatabase.database().reference() // or a Storage reference
// This might be the error
}
The reason why this happens is because , you are trying to initialise a variable with a class function/property which might not even be configured as of yet. So try this:-
class viewCon : UIViewController{
let ref : FIRDatabaseReference!
// This might be the error or a Storage reference
override func viewDidLoad(){
super.viewDidLoad()
ref = FIRDatabase.database().reference()
}
}
To support above theory, try using breakpoints on let ref = FIRDatabase.database().reference() and FIRApp.configure(), and see which one gets called first. If let ref = FIRDatabase.database().reference() is called first , you are bound to have this error, as ref is trying to access FIRDatabase class, which hasn't been configured yet..
