How can I debug a "Failed to install" message?

Question

I am currently attempting to develop a cross-platform mobile app using Xamarin.forms. As a part of this application I need to include a 3rd party .framework in my Xamarin.iOS project. I have successfully created a Xamarin.iOS Bindings Library .dll and included it in my project. I am able to reference the library and compile without errors, however when I attempt to deploy the app to the iPhone simulator the app will start and then crash with a “Failed to install” message.

Error Message

If I remove any lines of code which reference this .dll the app will run fine.

Does anyone have any insight on how to solve this?

Xamarin version: 16.7.000.440

Answer 1

From the apple document, the errors means you have linked the frame while does not ember it.

The app crashes at launch, because the dynamic linker can’t locate the missing framework.

So what you need to do is ember the framework and here is the document you can refer:
