Let me start by saying I have an iPhone and an iPad, both the latest generation and my second of each. I love the phone and want the pad to get better. I'm also a fairly staunch PC guy and legitimately prefer Windows to OSX for personal use and my own productivity.
It's also no secret that the number of Windows run machines still dwarf the number of Macs out there and that the majority of PC gaming and development is still Win-centric. This may be starting to shift with the explosion of mobile devices and (only slightly less mobile) tablet computers but availability, cost and familiarity still favor Microsoft. Lucky me right? I should have all the tools and tricks to design and produce my dream games. Well, yes, I'm indeed spoiled with tools. Pretty much anything out there is available for me if it is available for a Mac, some exclusively. The Autodesk and Adobe content creation suites, Blender, CryEngine, Source SDK, Unity , UDK, Corona, Shiva, Substance Designer, and tons more are all at my fingertips. Several of these support multi-platform delivery, even to mobile devices - but all require a Mac to successfully deploy to my iPhone!
So what's a PC toting would-be iOS developer to do? Start by whispering your thanks to a little company called Epic Games while crossing your fingers and praying Steve Jobs doesn't change his mind regarding whatever decision made the following little loophole possible.
UDK iOS Configuration Wizard
This little baby is your new best friend, in just a few short minutes it's gonna let you plug that iconic white cord into your Windows USB socket and wire your beautiful UDK mobile bytes straight to your iPhone or iPad, quite quickly I might add.
Ok, ok calm down, let's get the bad news out of the way, you DO still need a Mac running OSX Snow Leopard or higher, but you only need it for 10 minutes and then you can safely tuck it back into the closet. I suspect Apple is seeing a decent bump in Mac Mini sales of late for just this reason.
That's it, you're good to go. Build your game from your PC to your iPhone or iPad as many times as you need. Test, edit, repeat. When you're ready submit via Apple's App Store to share with the world.
