A simple developer's journey

[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:

As a good .NET developer, yesterday I installed the new Visual Studio 2015 IDE to discover all its new features... VS2015 installed ! I was previously developping mobile apps with Xamarin on VS2013. So as I am impatient I installed VS2015 without thinking of all the modifications it can bring to my environment... And bingo ! When I started back VS2013 to edit my Xamarin's projects, I had a bad surprise: iOS & Android projects no more compatible... But, fortunately, I find a really quick solution to restore Xamarin compatibility with VS2013. In fact in the windows programs / functionnalities menu, I  changed the Xamarin app components configuration like above: Xamarin, change installation Xamarin for Visual Studio 2013 is disabled ! Re-enable it and it s all good :) And go you can continue to develop Xamarin projects with VS2013 !
