Xamarin.iOS app crash on startup in simulator

I updated to Xamarin Studio 6 this morning. A beautiful update with dark mode, full Roslyn support and prettier icons. And it prevented my Xamarin.iOS app from starting in the simulator.

Problem

The splash screen was shown, followed by nothing. The OS X, sorry soon to be maxOS, Console.app told me that the following was wrong:

Symbol not found: _mini_parse_debug_option


console

Solution

I opened the project options for the iOS app and unticked the Enable incremental builds checkbox.
project_options

After rebuilding, the app started as it should.
