Hello,
Welcome to Microsoft Q&A!
We can use Hot Restart to debug iOS application without mac , notice that there are some limitations with it , and we will still need a Mac machine to do a full compilation, signing, and deployment for your application to production.
However , recently it seems something wrong with Hot Restart , the app crash at opening , the fix will be released in next visual studio version ,check this issue : https://github.com/xamarin/Xamarin.Forms/issues/13759 .
