xamarin.forms: ibtool exited with code 1, Compiling IB documents for earlier than iOS 7 is no longer supported

Question

Since, I upgraded to xCode 9 on my Mac I get the following error when compiling:

Error ibtool exited with code 1
Error Compiling IB documents for earlier than iOS 7 is no longer supported.

As suggested here I don't have a project setting in visual studio (on windows) with an option "Build for: iOS 10 and later".

Also, I'm working on a Xamarin.Forms project, so I don't have any storyboards. How can I solve this issue?

[EDIT] I'm working with the Visual Studio IDE on Windows. I use the mac only for building the iOS Apps.

The problem is that your deployment target in info.plist is set to 6.0. Set it to at least 7.0 and you will be fine.
