Unity Remote 4 iPhone PC NOT WORKING

Before anyone says anything I know that you can`t export your game to the App Store on a PC, you need a Mac. However, I want to develop my game for Apple products, (Im going to copy the project file onto a USB, and export it on my friend`s Mac to the App Store). I HAVE the downloaded the latest iTunes version, and Ive done Edit > Project Settings > Editor > iOS Device. But it still wont play. PLEASE HELP. Also I have looked through the Unity Manual multiple times already trying to find a solution.
