If you want to build iOS on Windows, you should obtain the GitHub build which is our source build. It’ll allow you to build code projects, as well as blueprint projects. Please also keep in mind that you cannot build for code projects on a Windows machine in binary, that’ll result in a failure. But blueprint projects will work.
If you are not interested in building code projects or using the GitHub (source) version of the engine, you will need to have a Mac in order to remote build from the Mac onto your Windows machine. Here is another link I found that provides additional information for remote building.
You can’t mix and match things from GitHub with your Binary/Launcher install. If you wish to build from PC using a remote Mac, you must install the GitHub version from scratch and not just pull items from it. Until you have done this, we have no way of knowing where your error is coming from because you are working in a way which is unsupported at this time and therefore, untested. Please download the entire GitHub version and build from there. Then, post as many logs as you can find from the failure. We do plan on supporting IOS builds from PC for 4.13 from the Launcher install.
