Same problem... exactly the same symptoms, all is fine in debug/dev... but broken in release, just when we need to delivery a customer :-(
I had to install again Xcode 11.7 on the mac (side-by-side with xcode12), download and install another previous instance of VisualStudio (16.7.3 to be xcode11.7 compatible), revert Xamarin.iOS (14 to 13.20) on the mac, etc... it takes me hours !
It's not the first time that "automatic updates" broke everything on our deliveries... and it makes years that we ask a "simple" process to revert to previous version/uninstall last updates".
Thanks for keeping us informed of this problem.

Thank you for your feedback!

For us to investigate this further, could you please provide your full build logs and a test case (so that we can reproduce the problem).

To get full build logs just set the log verbosity to diagnostic at the following locations:

  • On Visual Studio for Mac: Preferences > Projects > Build
  • On Visual Studio for Windows: Tools > Options > Projects and Solutions > Build and Run

On Visual Studio for Windows you also want to add -v -v -v -v to the mtouch additional arguments by right-clicking the project in the solution explorer and selecting Properties.

Note: this is done automatically on Visual Studio for Mac when the log verbosity is set to diagnostic.

We look forward to hearing from you!

In any case it's possible that adding --mono:static as an additional mtouch argument in your project's iOS Build options page could work around the issue.

rolfbjarne picture rolfbjarne on 16 Sep 2020

Thanks a lot @rolfbjarne for your quick response. --mono:static worked. Here is the build logs https://1drv.ms/t/s!Ap1zDOSzYJGY5RoD6j7UBgLn0_oj?e=1hnmKG

I switched to stable branch but use the Xamarin.iOS pkg for iOS 14

Here is the build logs

I'm sorry, I was unclear, but could you attach a build log _without_ the --mono:static argument? I'd like to figure out why the problem you were having and fix it if I can.

I've faced similar issue - after any code changes if I try to start debug I'm getting app crash with the following error. After full solution rebuild debug has starting.

Please check if this applies to you:
https://www.reddit.com/r/xamarindevelopers/comments/iys4tw/do_not_use_xamarinformsvisualmaterial_for_ios_apps/

Citate: _The bad thing is, that this only happens using Testflight or App Store distribution. If you send the app to the device manually (eg debug from Visual Studio) or using AdHoc mechanisms, it works like a charm. Unfortunately, because of this, you may realize the issue only in the last phase while trying to distribute it._
