MAUI - IOS Emulator / Building without MAC
It seems nearly impossible to run an Iphone emulator without a Mac or Iphone device.
You could invest in a Mac / Macbook or reason to get something cheap refurbished for a few builds.
But for my development, http://www.macincloud.com was sufficient and quite fast to continue my work.
Just make sure to get the option to SSH - so you can pair your "Mac in the cloud" to your Visual studio.
Use the credentials that come with the subscription.
Once it is paired, you then can debug on an Iphone Emulator
