Most of "so called Windows solutions for iOS development without Mac" require Mac at the end just to sign and send to app store. I checked a few, not all though (who has the time?)
At the end it's just too much trouble to learn "their super special easy way to program iOS without Objective-C", they have lots of bugs. Really the goal they are setting is unachievable in my view.
Also a lot of time they make you use Objective-C equivalent statements simply in another language. They kind of look the same but there are always subtle differences that you have to learn on top of obj-c. Which also makes even less sense, because now instead of learning less you have to learn more. So where is the gain? Also they cost a lot, because they are very hard to develop.
Many lack any debugging abilities whatsoever.
In my honest opinion, if you are a hard-core iOS developer then for sure buy the best Mac and learn objective-c. It's expensive and takes time, but if it's your path, it's worth it.
For an occasional use, it's just easier to rent a remote Mac service, like XCodeClub.com
