How can i build IOS app from my windows 10 pc

how cam i buiifd my game project to ios with my windows pc to IOs platform

You can use Unity cloud, but first build should be configured from MAC (only once).
Other solution is to use Unity Remote. It is just streaming image from Unity Editor to iOS.

But better to find MAC.

Xcode from Apple was created only for macs and releasing ios app depends on it (if you want it in the app store, but it cost money).
Sorry for english.
