Answer 1

For ios you need to set your bundleIdentifier also in Xcode.. and in Windows10 Xcode not available. you need mac for building & running ios app.

Answer 2

First of all you can't do that in windows environment. Either you need to a virtual machine set up in your windows machine or explicitly a ios machine borrowed from a friend. And then you need Xcode installed in it. All the development projects' builds create a file that can be open inside Xcode. Then only you can run it on an ios emulator or debug using a real iphone device.
