Darvos,
Code iOS projects on Binary (Epic Games Launcher version of the Engine) will not package or launch on iOS devices. Please make sure that you are using a Mac in order to package your iOS project. You may also want to check that your XCode is up to date and that you’re not using a beta version.
I also browsed through and found UE-16236 which is a bug stating that Windows code projects fail to package on iOS devices from GitHub.
Thanks!
