MAUI - IOS Emulator / Building without MAC

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.
