Nope and i think it always been unavailable as Apple does not provide iOS developement tools on Windows
Hi, the IOS platform used to be available on windows now suddenly with 4.0.2 its gone… Is there any way to get it back?
Hmmm… well I can post a screenshot to prove it was available on windows. I am happy to build on my mac but it is not powerful enough to develop on.
I don’t see how thats even possible, there no tools for Windows in order to make it build on it 
wither way you don’t need powerful computer to build iOS package of your game, right?
It is technically possible to do this through the Source (Github) version, though it is not supported by us. There is currently no way to select the iOS platform while on the windows platform using the Binary (Launcher) version.

I saw a card over at trello, which mentions that work is going on to build for ios from Windows… And is expected in May!!
I hope that is correct. I do own mac, but i believe it is currently out of shape for UE4 specs.
Will be running a test soon though and report back.
