ddyl: Library not loaded

[mwiszomirski]

I run my Xamarin ios application on simulator, and it runs perfectly fine. However when I try to run it on my own device (iPhone 6s) it crushes at the start. I tried multiple things and seen similar issues but nothing helped so far. This is an output in the console:

Application 'com.appsbymarcin.Choosy' terminated.

@mwiszomirski Can you upgrade to most recent version and try again? Please, remove bin and obj folders and XBD cache. Thanks in advance!

I have the same problem with Xamarin.Firebase.iOS.Auth package. Simulator works fine, but the application crashes when is launched on a real device:

@Castaneda1914 Can you share a test case, please? Thanks in advance! I have just tested our sample and everything seems to be working ok.

@SotoiGhost My test case is pretty simple - launch VS for Mac, create new iOS single view application, add the last version (right now it is 6.5.1) of Xamarin.Firebase.iOS.Auth package and add code

var authResult = await Firebase.Auth.DefaultInstance.SignInAnonymouslyAsync();

to ViewController's ViewDidLoad method. That's all.

I have been experiencing this with firebase and other libraries since 8.6 VS and associated mono upgrades.
A full clean and rebuild and it works, change one line of code and build again and a bunch of libraries such as firebase are suddenly not part of the .app package
