Publishing issue, Callkit is included even we are

Question

Good afternoon everyone today we have received a call from Apple saying that Callkit, included in our app, will block the app approval process.

Apple discovered an issue with Callkit and all the apps with a reference to callkit won't be published.

The problem is that we aren't using callkit but it's included in the assembly Xamarine.Ios , the main assembly for an Ios Xamarine project.

Is there a way to go over this problem by your opinion, by removing or similar stuff this reference? Thank you very much for your appreciated help

Answer 1

By default your device builds (including the one you submit to Apple) should have the managed linker enabled (with Link SDK setting).

That will remove any trace of CallKit (and a lot of other unused stuff) from the Xamarin.iOS.dll that ships with your application.

That is unless it's used elsewhere inside your application (or 3rd party code), in which case the linker won't be able to remove it.

Answer 2

I had the same issue. I had to use find / -type f -exec grep -H 'CallKit' {} \; inside your project folder to find which app/framework is using it. It was a third party framework using CallKit.
