[Xamarin Forms Shell App + Firebase iOS Auth plugin v. 6.9.2] Last day I added the Google Firebase functionalities to my project, but unfortunately I add some errors just after installing the Firebase Plugin. > Xamarin Forms (Shell app) + iOS Firebase errors adding latest package: ....iOS/MTOUCH: Error MT5210: Native linking failed, undefined symbol: _GULIsLoggableLevel. Please verify that all the necessary frameworks have been referenced and native libraries are properly linked in. (MT5210) (*.iOS)  I found some solutions, and finally the iOS SDK worked with my Xamarin Forms Shell app... Unfortunately, with Xamarin Forms, we still take too much time to solve this kind of problem.  What did I do ? iOS project properties => Set the "entitlements file property" to a default file (the *.plist file can be empty): => iOS Build options: - Add 'mtouch' argument: --registrar:static - and try to set linker behavior to SDKs only Then initialize Firebase in your code:

Xaml build error For one of my Xamarin project, I just had this build error: This error was related to my XAML code : Unable to cast object of type 'Xamarin.Forms.Xaml.ElementNode' to type 'Xamarin.Forms.Xaml.ValueNode' After searching for a long 'moment', I just didn't understand what happened... My investigation (this process can help you :p) So I decided to remove a large part of my xaml code and then re-add it little by little. Each step I tried to compile to see when error occurs. So In my case, I determined that the piece of code that was going wrong was the following: Ok, it was my mistake but in the code editor, Visual Studio didn't tell me anything. I was trying to bind an event ( I though it was a property ) to a DateTime property... What is not possible. Hope this helps someone to save a few minutes :)
