How do I set up a development environment / IDE for Mono C# iPhone apps on Linux? I seem to be stumped. I have heard that you can use Xamarin, but there doesn't seem to be a Linux version. Xamarin.com redirects to a Microsoft VS download page with only a Windows download link.
I found this question which asks about developing cross-platform applications but does not specifically mention using Linux as a development environment. Additionally, the links in the top answer are both dead. I searched for MonoTouch and found this Xamarin site, so it seems to be a part of Xamarin, which doesn't seem to be available for Linux...
I also thought I may be able to develop an iPhone app using MonoDevelop, which I already have installed and have used to develop Linux applications on Linux for Linux. I can't seem to find any articles online about how to do this. The "Portable Library" project template in MonoDevelop mentions support for "Xamarin.iOS", but I don't want a library, I want a GUI app.
