Using alternative device instead of Apple device

Dear Professor Patterson,
I am really sorry to say that I am doing the course ‘Foundation of Objective-C App Development’, but I don’t have Apple Laptop or Computer. So, I am using Asus Laptop as I have and visual Studio 2017.
But the point is that, Would you mind to suggest me how I can complete the course by using my laptop?
If I use C# language to make this project by using visual studio, will it be acceptable or not ?
Due to this mentioning problem I can’t make the project and submit the assignment for review.

I will be very delighted if you give me any suggestion which will be beneficial for me regarding this issue.

Have a good time!

Looking forward to getting your response.
