Hello @henrik-stromberg-tetrapak, thanks for reaching us!

The broader developer community would be the best and quickest place for additional troubleshooting help on this issue, this is the development repository of the Xamarin.iOS/Mac SDK.

Posting a question on Stack Overflow [0] or the Xamarin Forums [1] would be the best next step.

(Investigation by the Xamarin team in the bug tracker for an issue like this would usually require that the reporter include additional background info to hint that Xamarin is behaving differently compared to Xcode.)
