Yes! i too, want to know how?
the last i heard you need a Mac to code IOS apps.

"To develop iOS apps using the latest technologies described in these lessons, you need a Mac computer (macOS 10.11.5 or later) running the latest version of Xcode. Xcode includes all the features you need to design, develop, and debug an app. Xcode also contains the iOS SDK, which extends Xcode to include the tools, compilers, and frameworks you need specifically for iOS development.
