I'm trying to integrate Firebase Analytics to my xamarin forms application. For Xamarin.IOS I'm using Xamarin.Firebase.iOS.Analytics version 5.0.1
And getting the below error while building.
./iOS/MTOUCH: Error MT3001: Could not AOT the assembly '/iOS/obj/iPhone/Debug/mtouch-cache/Build/Firebase.Analytics.dll' (MT3001)
Not able to understand what could go wrong. Is there any configuration changed I have to do.?
Firstly ,make sure that your VS and Xcode are up-to-date. If the issue continue, you can right
click your project ->options->iOS build ->Linker Behavior
set the value as Don’t Link. In addition, delete the folder obj and bin and rebuild your project again.

Locally, I can build and run my Xamarin Forms application with no issues. In my Azure build pipelines I have my master branch failing because of my target framework version. It says it is 9.0 when it should be at least 10.0.
In my Android project file I have the framework version set to 10.0. I have made sure it is also v10 in the properties tab for the project. Yet I still get the below error.
##[error]C:\Users\VssAdministrator\.nuget\packages\xamarin.forms\5.0.0.2012\build\Xamarin.Forms.targets(188,5): Error XF005: The $(TargetFrameworkVersion) for MyApp.Android (v9.0) is less than the minimum required $(TargetFrameworkVersion) for Xamarin.Forms (10.0). You need to increase the $(TargetFrameworkVersion) for MyApp.Android.
Try to open your .csproj file,and manually modify its targetFrameworkVersion.
<TargetFrameworkVersion>v10.0</TargetFrameworkVersion>
Verify that BOTH of the following project properties are set to 10.0:
Application / Compile using Android version (Target Framework).
Android Manifest / Target Android version.
https://learn.microsoft.com/en-us/xamarin/android/app-fundamentals/android-api-levels
If those are already both 10.0, then make sure the Azure build pipeline has up-to-date versions of Android SDKs and tools.
Another way to fix:
If you are able to create a new sample solution, and successfully build that via Azure, then start a new solution, and add all your files to it.
I am using Visual Studio 2019 on Windows, developing an App using Xamarin Forms, for Android and iOS. Everything is the latest version.
I am trying to use Firebase to add Push Notification functionality. I have been able to get this functioning for the Android App, but whatever I do seems to fail / not work for iOS.
I have tried using both Xamarin.Firebase.iOS.CloudMessaging and Plugin.FirebasePushNotification with the same result. Starting from a basic app created in Visual Studio, as soon as I add the basic code for the iOS project, the app stops working and just times out after 17 seconds with running any of the project code (no breakpoints are hit).
I also tried downloading this demo app https://github.com/jfversluis/XFFCMPushNotificationsSample. I created my versions of google-services.json (Android) and GoogleService-Info.plist (iOS). The Android app runs but the iOS app does not (times out after 17 seconds).
Having tried so many different samples, examples, options, etc - I am at a complete loss as to what the issue might be. The situation is not helped by me being new to App development & Xamarin Forms!
I appreciate that I haven't added any "I tried this" code, but I'm hoping someone can help me with debugging this. Visual Studio doesn't appear to show anything, can I get more helpful info from the iPhone?
Edit:
For iOS,
I have created a Key and enabled Apple Push Notifications.
I have uploaded the key to the iOS project in Firebase (Cloud Messaging).
I have downloaded the GoogleService-Info.plist file and added it to the iOS project in Visual Studio, and set it to BundleResource
I have enabled Push Notifications in Entitlements.plist
I have enabled Background Modes & Remote Notifications in Info.plist
I am using Automatic Provisioning
I have checked that Bundle Identifier is correct
I have added FirebaseAppDelegateProxyEnabled to info.plist
EDIT 2:
I have manged to get an error message, which happens during the call to
FirebasePushNotificationManager.Initialize(options, true);
{System.NullReferenceException: Object reference not set to an instance of an object.

I am trying to compile a newly created Xamarin.Forms solution using Visual Studio Pro 2019 version 16.1.3. I use the stable Xamarin.Forms version 4.0.0.425677. The solution contains an iOS, Android and UWP project.
When I try to compile I get the following Android compilation error even without having made any code changes.
C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(3326,2): error : A part of the path "AccessibilityManagerCompat_AccessibilityStateChangeListenerImplementor.class" could not be found
The only related post I found was here which recommends to delete bin and obj folders in the Android project. This does not apply since I start with an new solution in the first place. Any ideas what the cause could be?
Well, it turns out that I only get this issue when I have the term "Xamarin" in my Android project name. This seems to confuse the Android compiler.
I am getting an error in Xamarin when building a release version. I actually have never released code before, and i have no idea what im doing. if you could tell me, i am getting this error but i do not know how to follow the instructions because my Visual Studio doesnt have a menu called properties
Debug is not enabled in the current configuration. Please Start
Without Debugging or change it in Properties -> iOS Build.
Right click to IOS project--> open Proprieties page and enabled debug for IOS
I'm having a little problem. When I try to deploy an unity3d app with the auth sample project from firebase I'm getting this error "error building Player: iOS framework addition failed due to a CocoaPods installation failure" but I have installed cocoapods correctly, I even uninstalled it and reinstalled it. I only get this error with the auth project, not with the database. I tried adding the cocoapods to the project with the terminal using pod init instead of having unity do it but nothing seems to work
From https://github.com/firebase/firebase-ios-sdk/issues/1845#issuecomment-425184012:
We're working on patching the Firebase C++ and Unity releases to migrate them to the 5.9.0 iOS SDK. In the meantime, under Assets/Firebase/Editor/ there are a set of files matching *Dependencies.xml files (e.g AnalyticsDependencies.xml) that reference the iOS SDK version. You'll need to modify the section of each file to reference iOS SDK 5.9.0 rather than 5.6.0.
