As I was working on my iOS app, I got this error out of no where
Terminating app due to uncaught exception 'FIRAppNotConfigured', reason: 'Failed to get default Firebase Database instance. Must call `[FIRApp configure]` (`FirebaseApp.configure()` in Swift) before using Firebase Database.'
on the line initializing DB_BASE
var DB_BASE = Database.database().reference()
class DataService {
static let instance = DataService()
}
I have FirebaseApp.configure() in my didFinishLaunchingWithOptions AppDelegate function, so I'm not sure what the error is all about. I've tried updating pods, restarting my computer, but no luck so far.
I haven't worked with Database specifically, but we use Storage, Analytics and Remote Config. Have you put google-services.json to the root of the project?
The code you provided doesn't make it totally clear, but if DB_BASE by any chance is a member of a singleton (like DataService.instance), try moving it to a different place. Static variables get inited before applicationDidFinishLaunching is called.

I updated firebase and since then my app keeps crashing with the following error

the call that I make and crashes is the following:
let reviewsRef = Database.database().reference()
reviewsRef.child("reviews").queryOrdered(byChild: "timestamp").queryLimited(toLast: count)
I added a debug log and the call is made only once.
It seems the line that the app is crashing is
let ref = Database.database().reference()
Did anything changed regarding configuring Firebase from 4.9 to 5.0 version?
Another update:
It seems to be working on the Xcode simulator but not on device. Device is iPhone 6s with 11.4
Kind of working since on simulator I receive the whole database instead of only the "reviews" that I am requesting
if the rules are:
{
"rules": {
".read": true,
but when I change to:
"rules": {
"reviews": {
".read": true,
I get permission denied(on simulator).It has to do maybe with authentication? I understand that those 2 might be two different issues.
I have no idea why this happened on the first place. But I created a new project in firebase with exact same rules and it worked... for some reason the specific project became corrupt on firebase side.
NRMAURLSessionTaskDelegate indicates usage of New Relic - if it worked on a clean project there might be an incompatibility with Firebase
the Firebase configuration is not working even though it is called in the app delegate method
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FirebaseApp.configure();
confic(application: application);
return true
}
I did not had this problem before where my classes were initialised as singletons those particular classes are dependent on Firebase however I decided to instantiate them individually in each view controller instead of using singletons however now I'm getting this issue can anyone help?.
I also tried removing any calls to Firebase from the Appdelegate class and just have FirebaseApp.configure(); included in the delegate however this did not help either.
theconfic(application: application); method contains all my Firebase related calls such as checking if the user has logged in etc.
I moved in here as in previous post I read this may help however it made no difference still getting the same error

I've got Fabric installed in my app, with Crashlytics enabled via a simple Fabric.with([Crashlytics.self]) call in AppDelegate. Everything was working great, until I pulled in Realm. I have a dead-simple function;
class func listObjects() {
let realm = try? Realm()
if let realm = realm {
let objSet = realm.objects(TestObject.self)
print("Retrieved \(objSet.count) objects")
}
}
Calling the function actually works just fine, but I get an odd warning;
[Crashlytics:Crash] Warning: NSUncaughtExceptionHandler is '_ZZ34RLMInstallUncaughtExceptionHandlervEN3$_08__invokeEP11NSException' in '<...>/Frameworks/Realm.framework/Realm'
Has anyone come across this before?
I guess this is happening because Crashlytics checks whether the uncaught exception handler is overridden, because it is relying on that itself, but it is commonly misused for purposes where there would be less dangerous solutions. 🐉
Realm is using this for good reasons: we need to tear down open write transactions. While we are doing that, we still ensure to call the previously configured exception handler as you can see here. So Crashlytics won't loose it's ability to report any exceptions in your app.
Hi I get the following error that I have inherited from a previous developer. My app keeps crashing with the following :
2016-06-21 22:26:16.828 Drnk[3234:1081556] The default app has not been configured yet.
2016-06-21 22:26:16.832 Drnk[3234:1081556] *** Terminating app due to uncaught exception 'MissingDatabaseURL', reason: 'Failed to get FIRDatabase instance: FIRApp object has no databaseURL in its FirebaseOptions object.'
*** First throw call stack:
My App delegate has the following code:
FIRApp.configure()
My controller where I call the database and the app crashes has the following code:
var ref: FIRDatabaseReference!
self.ref = FIRDatabase.database().reference()
I have added the google-services-plist file to my project as instructed.
This all works with another app I am developing but I can't solve this.
Make sure you're not calling FIRDatabase.database().reference() before viewDidLoad
In your class define a var:
var ref: FIRDatabaseReference?
then in viewDidLoad
ref = FIRDatabase.database().reference()
This is how I fixed it here https://stackoverflow.com/a/65866188/4833705
I didn't want to add the same code twice and the comments are kinda long so someone might miss this.
Download and replace the GoogleService-info.plist again since you have already registered the database in your account
I was trying to follow the advice and remove the listener when needed and register the listener when needed. So in my UIViewController.viewDidAppear I have the following:
let chatRef = messagesRef.childByAppendingPath(chat.objectId!)
var query = chatRef.queryOrderedByChild("createdAt")
if let since = since {
query = query.queryStartingAtValue(since.timeIntervalSince1970 * 1000)
}
let handle = query.observeEventType(FEventType.ChildAdded, withBlock: completion, withCancelBlock: { (error: NSError!) -> Void in
println("error listening for new Chat messages: \(error)")
});
In my UIViewController.viewWillDisappear() I have
let chatRef = messagesRef.childByAppendingPath(chat.objectId!)
if chatRef != nil {
chatRef.removeAllObservers()
}
But the program crashes every time the ViewController is entered the second time (going to the view controller, navigate away, then come back) with the following error:
*** Assertion failure in -[FPersistentConnection listen:tagId:hashFn:onComplete:], /Users/mtse/Dev/firebase/firebase-client-objc/Firebase/Firebase/Core/FPersistentConnection.m:127
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'listen() called twice for the same query'
The program runs fine if I don't remove the observers and call observeEventType only once in viewDidLoad instead of viewDidAppear.
The program also runs fine even if I remove the observer then add it back if I don't do queryOrderedByChild and queryStartingAtValue.
So what am I doing wrong here?
Disclaimer: I work for Firebase
Listeners in Firebase are specific to the path or query that you register them on. Calling removeAllObservers() removes all observers, but only from that path.
So in your viewWillDisappear() you will need to remove the listeners from the query, instead of the ref.
query.removeAllObservers()
We just made this more explicit in our documentation and are looking at ways to make the API more intuitive.
Update (20150724)
It turns out that calling removeAllObservers() on a FFirebase should remove all observers on queries on that same location too. It will not remove observers at child() locations, but should have worked in your case.
We are investigating what is going wrong, but it seems you have hit a bug in our iOS SDK. Once we find it, we'll release a fixed version. In the meantime the above serves (and will continue to serve) as a valid workaround.
