Producing and editing unity 3D games involves planning, original painting design, 3D modeling, art and texturing, action binding editing, special effects editing, and unity programming. It is a systematic project with a long cycle. To elaborate, several books could be published.

Here is an introduction to game publishing: IOS game project editing can be operated on WINDOWS. But publishing requires a personal computer with OS X operating system.

Install the XCODE compilation system and the mac version of UNITY 3D on the OS X system. Then you need to apply for an Apple developer account. (Application and payment require foreign accounts and foreign credit cards, US$99 per year)

After importing the edited project into the mac version of UNITY 3D (of course, you can also create and edit the game directly in the mac version of UNITY 3D project), choose to publish the IOS game project as an xcode project file.

Import the xcode project file into the xcode compilation system, modify it to your own program signature, and you can compile and publish the IOS ipa program.

After that, you can directly install the ipa program on your mobile phone for testing.

Or upload the ipa program to Apple's electronic store, once it is officially certified by Apple. Your game can be sold to the world, and dollars start flowing into your account.

I have not tried the method of cracking Xcode and IOS devices to achieve certificate-free real-machine testing, because that method cannot upload the ipa program to Apple's electronic store, and the developed games cannot be installed on ordinary IOS devices. There is no way to charge.
