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.

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

2019-08-03: updated link to getting started NuGet

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:

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])
