Does iOS support a PC editor for level editing and basic viewport testing/scripting?
I’m guessing no, but I’m hoping yes. I’m also guessing i am going to be able to open my unity iOS project in just the standard unity version on PC for dev. But I’m not sure.
Nope iOS project type etc is OSX eclusive.
so no remote support, emulation and other things on windows, you can only develop the other project types there
but i can open a unity iOS project in either unity free or pro correct? just no emulation, but fine for level building/scripting
It just won’t be an iOS project anymore, so neither the script framework restrictions apply nor anything else.
As such its not the best idea as you want to test early on the first time to see if subsystems you use are not compatible at all (thats just a recommendation from my end after having to pull in a 36h session to overcome limitations that didn’t exist in the editor when deployed to the device cause we didn’t do daily deployment and run tests on that project)
I see, test on mac osx only. gotcha
naw test on iOS device only 
“get an idea on the outcome” would be iOS only 
as well as experiencing the input (as iOS project type is required for remote and remote for usage of device as input device)
We started our game development on our christmas game on a windows computer… Then started to port to iPhone when we purchased unity iOS.
That wasn’t the greatest idea.
Our Game runs terribly on an iPhone 3G (great on a 4…), and now we are extremely behind schedule, and may not even be able to release it before christmas (which is bad, as it is a christmas themed game!)
So my word of advice - try not to build for iOS on windows or without unity iOS.
It is always a terrible idea to develop for a specific set of target hardware without testing on that hardware from the very beginning. The only thing that would make this remotely reasonable is if you were developing for Android first, and planning on porting to iOS later.
