I am new at Swift. I am creating my own framework that will use Firebase for in-app messages.
I tried to install Firebase through Cocoa pods, but it has issues: when I do that for my framework, then for sample project I have to install Firebase again. And then I get the numbers of warnings like this:
Class Firebase is implemented in both /private/var/containers/Bundle/Application/AD85D7EC-2652-4019-94FB-C799D0FBA69B/MyFrameworkExampleApp.app/Frameworks/MyFramework.framework/MyFramework (0x1019a0438) and /var/containers/Bundle/Application/AD85D7EC-2652-4019-94FB-C799D0FBA69B/MyFrameworkExampleApp.app/MyFrameworkExampleApp (0x10107c558). One of the two will be used. Which one is undefined.
my app crashes at runtime due to these warnings
So I don't want to use cocoa pods in Framework but need Firebase in my project.)
.
I follow the steps:
"https://firebase.google.com/docs/ios/setup#frameworks"
I just download the firebase file and import it into my project. after this I try to:
import Firebase
at the top of my swift class but the compiler is giving me an error.
No such module 'Firebase'
I am using Xcode 9. swift 4.
All of the framework files are in
"Targets > FrameworkName > General > Linked Frameworkd and Libraries".
also in the
"Targets > FrameworkName > Build Phases > Link Binary with Libraries".
I also followed this tutorial:
http://www.mokacoding.com/blog/setting-up-firebase-without-cocoapods/
but nothing happened.
Where am I wrong and What should I do?
Try adding following #import to framework's public header file "YourCocoaTouchFrameworkNameSwift.h"
#import <YourCocoaTouchFrameworkName/Firebase.h>
Check this link, if you need more information.
in firebase we have not a .framework file for import firebase. As we know that firebase is a combination of different frameworks, so we were unable to import firebase directly. thats why we
import required framework and dependent framework separately.
Dont try to import whole firebase.

The Firebase docs provide several ways to import SDK in service worker, which confused me. Here are the methods I discovered in the documentation:
https://firebase.google.com/docs/cloud-messaging/js/receive#web-version-9
import { initializeApp } from 'firebase/app';
import { getFirestore, collection, getDocs } from 'firebase/firestore/lite';
I can't utilize the method since I can't process my service worker because my project still uses webpack version 1. So I'm going to concentrate on the 'importScripts' techniques I discovered.
https://firebase.google.com/docs/cloud-messaging/js/receive#web-version-8
importScripts('https://www.gstatic.com/firebasejs/8.10.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/8.10.0/firebase-messaging.js');
This is a working approach that I've tested; nevertheless, I have some questions about it:
Is it okay to use this gstatic domain in production?
This official SDK differs from the quickstart-js that they gave.
https://github.com/firebase/quickstart-js/blob/master/messaging/firebase-messaging-sw.js
importScripts('/__/firebase/9.2.0/firebase-app-compat.js');
importScripts('/__/firebase/9.2.0/firebase-messaging-compat.js');
importScripts('/__/firebase/init.js');
This is from the official example quickstart-js, however I still have a lot of questions about it:
It appears that they automatically updated the sample SDK, but the current version of Firebase is 9.6.1, not 9.2.0; should I remain with 9.2.0?
This approach only works in projects hosted by Firebase, and I can't find the init.js file matching to gstatic at the third line; is there a way to directly access that file?
Which approach should I utilize?
And I'm currently using Firebase 9.6.1 outside of my service worker; would utilizing Version 8 within my service worker cause any issues?
I think I'll stick to this:
importScripts('https://www.gstatic.com/firebasejs/9.6.1/firebase-app-compat.js')
importScripts(
'https://www.gstatic.com/firebasejs/9.6.1/firebase-messaging-compat.js'
)
i am trying to use firebase new feature which is App check for flutter app in android emulator.
i am trying to activate the debug provider for android by following this instructions app check .
for line "firebaseAppCheck.installAppCheckProviderFactory(
DebugAppCheckProviderFactory.getInstance());" , i got error message that says The method 'installAppCheckProviderFactory' isn't defined for the type 'FirebaseAppCheck'
does anyone know how to solve this problem
I have run into the same problem myself.
It's not stated on this page but the imports you need are:
import com.google.firebase.FirebaseApp;
import com.google.firebase.appcheck.FirebaseAppCheck;
import com.google.firebase.appcheck.debug.DebugAppCheckProviderFactory;
I'm following this tutorial that uses Ionic framework and Firebase backend to create an image recognition app https://www.youtube.com/watch?v=taPczl94Eow
For this line:
import * as vision from '#google-cloud/vision'
I keep getting the error:
Could not find a declaration file for module '#google-cloud/vision'.
'/Users/Private/Workspace/project/functions/node_modules/#google-cloud/vision/src/index.js' implicitly has an 'any' type.
Try `npm install #types/google-cloud__vision` if it exists or add a new declaration (.d.ts) file containing `declare module '#google-cloud/vision';`
What should I do? I already installed it properly. I also enabled the API from the GCP platform and followed their instructions
I was also having the same problem, so I had to replace this line:
import * as vision from '#google-cloud/vision'
For this line (it works with Typescript):
const vision = require('#google-cloud/vision');
I hope this works for your case.
Could anyone please help me in how to use Xamarin.Firebase.iOS.Crashlytics nuget package for Xamarin iOS. I am getting SIGSEGV code error in my code at random places and I am not able to figure out the actual problem.
Have searched a lot regarding how to implement Crashlytics in Xamarin iOS , but I was not able to find any.
Have followed the steps given in the below two links, but I was only able to implement Crashlytics in xcode with the help of these two links.
Link 1 Link 2
not sure if you solved the problem already or not but I will give it a go since this post almost got me to the finish line. And there might be others out there looking for how to do this.
As of late 2018 the Crashlytics is going from Fabric to Firebase this has resulted in a lot of old posts that are not applicable any more.
To get nuGet package to work you will need to do the following:
Head over to the firebase console and create a project. Then add an app input a "bundle ID", this needs to be the same as what you have in your xamarin app. The nick and App Store ID is optional.
You will now get a GoogleService-Info.plist file, download this file. Now comes the the tricky part. To initialize the firebase app you need to create a dummy xCode project with the same bundle identifier as your project to do this:
Make a new xCode project and follow the instructions from firebase
Remember to use the .xcworkspace file to open the project after insatlling the pods.
Compile and run this app on a device in the firebase console you will hopefully see some reaction if everything has worked out correctly.
Now to add this to your visualStudio xamarin app first include the GoogleService-Info.plist to your project and change the build action to "Bundle Resource"
Then add the Xamarin.Firebase.iOS.Core and Xamarin.Firebase.iOS.Crashlytics packages to the iOS project.
Almost there, only two things left to do.
In the AppDelegate.cs file in the FinishedLaunching function add:
Firebase.Core.App.Configure();
Crashlytics.Configure();
Fabric.Fabric.SharedSdk.Debug = true; // To enable debugging
and also remember to add the two namespaces Firebase.Core and Firebase.Crashlytics to the top of the file.
The last step is to run the app witout the debugger as the debugger will eat all the errors.
This should be it.
More info on the crashlytics nuGet see the github page
Edit
2019-08-03: updated link to getting started NuGet
PLEASE CHECK THE COMMENTS
For iOS:
Add GoogleService-Info.plist file to your app project.
Set GoogleService-Info.plist build action behaviour to Bundle Resource by Right-clicking/Build Action.
Add the Xamarin.Firebase.iOS.Core NuGet to your iOS project: https://www.nuget.org/packages/Xamarin.Firebase.iOS.Crashlytics/
Add the following lines of code somewhere in your app, typically in your AppDelegate’s FinishedLaunching method (don't forget to import Firebase.Core and Firebase.Crashlytics namespace):
App.Configure ();
Crashlytics.Configure ();
For Android:
Make sure you have a project set up in the Firebase Developer Console.
Download your project’s file and place it in the folder of your Xamarin.Android project.
Add the Xamarin.Android.Crashlytics NuGet package: https://www.nuget.org/packages/Xamarin.Android.Crashlytics/
Restart your IDE
Add google-services.json to your Xamarin.Android app project.
Set the build action google-services.json to GoogleServicesJson
Create a string resource with the name com.crashlytics.android.build_id. The value can be whatever you want to uniquely identify a particular build with.
Clean and Rebuild your solution.
Fabric.Fabric.With(this, new Crashlytics.Crashlytics());
Crashlytics.Crashlytics.HandleManagedExceptions();
I had recently written a blog for integrating your Xamarin Apps with Firebase Crashlytics where I have gone in detail on how it can be configured which can be found here:
https://medium.com/#hakimgulamali88/firebase-crashlytics-with-xamarin-5421089bb561
There are few steps needed to be performed in order to implement Firebase Crashlytics in Xamarin.
First of all you have to create a dummy project in Xcode with same bundle identifier.
You can follow this https://fabric.io/kits/ios/crashlytics/install , to implement Crashlytics in Xcode.
Now for Xamarin, use the same Bundle Identifier, and in the info.plist file add the below lines
<key>Fabric</key>
<dict>
<key>APIKey</key>
<string>Your api key</string>
<key>Kits</key>
<array>
<dict>
<key>KitInfo</key>
<dict/>
<key>KitName</key>
<string>Crashlytics</string>
</dict>
</array>
</dict>
Now import Fabric and Crashlytics in the AppDelegate , then initialize Fabric instance with:
Fabric.with([Crashlytics.self])
When application load in browser, it gives following warning. So unable to create build for prod (ng build --aot --prod)
It looks like you're using the development build of the Firebase JS SDK.
When deploying Firebase apps to production, it is advisable to only import
the individual SDK components you intend to use.
For the module builds, these are available in the following manner
(replace <PACKAGE> with the name of a component - i.e. auth, database, etc):
CommonJS Modules:
const firebase = require('firebase/app');
require('firebase/<PACKAGE>');
ES Modules:
import firebase from 'firebase/app';
import 'firebase/<PACKAGE>';
I am using following configurations
Angular CLI: 1.5.0
Node: 9.8.0
Angular: 5.1.3
"firebase": "^5.0.4",
"angularfire2": "^5.0.0-rc.10"
Please guide where I get wrong.
There is nothing really wrong, it is more a warning and a best practices tip.
Firebase is composed of different services/modules, e.g. the Real Time Database, Firestore, the Auth service, etc.
In the majority of projects one does not use ALL those services and therefore this warning indicates that instead of importing all the services with one global import it is better to only import the services you really need in your application. In such a way, your build will be optimized: the resulting build file(s) will only contain the Firebase SDK code that you need and will not contain the parts that are not used.
See this documentation item: https://firebase.google.com/docs/web/setup and in particular the part that says:
If you are using a bundler like Browserify or webpack, you can just
require() the components that you use.
Update following your comment:
With the import keyword, you should do as follows:
import messaging from 'firebase/messaging';
You did not share your Angular component code that's why I could not give you specific code. However, I guess, you include Firebase directly like this then it will show following warning.
import * as firebase from 'firebase'; // It will throw warning
import * as firebase from 'firebase/app'; // It will not throw any warning
Then include specific package acccording to your need.
import 'firebase/firestore';
import 'firebase/database';
import 'firebase/auth';
I add following code, it works for me
require("firebase/messaging");
