Source: Microsoft Announces Xamarin Live Player Preview - Thurrott.com
Awesome announcement from Microsoft. Apparently using Visual Studio you will be able to deploy test builds to iOS devices straight from a PC.
Anyone know if/when we will see this working with Unity?
What? 
You still need a Mac to promote though, no?
+1 on the question.
+2 on question.
Not to deploy and debug with XLP and VS2017.
I think he meant to say publish not promote, and yes that still requires a mac. Although submitting to Itunesconnect is usually fairly quick and you could either borrow a friends Mac or head to a local library.
I am assuming this would work similar to the phonegap app, so yes for final builds you would still need a mac but would be able to test with out one locally
… to test locally and with the code executed on the testing device, not on the editor.
