I have no experience with Objective-C and I know iOS simply as a user of iphone and ipad devices.

Now, I know that Unity3D can port my game to iOS without needing to know Objective C (that's what their docs say). But is it as simple as that? Click to compile, then use distribution profile and upload binaries to iTunes - as simple as that?

I need to know if should I start this process and publish my game this way. I am afraid that I may come across platform-dependent things (like when I code in cocoa-2dx using C++ and I come across hardware specific things).

If anyone has such experience, I would appreciate they share it with me.

So, from your end, no objective-c is involved. The only thing here is to have a device on which you can physically test. \$\endgroup\$ – XNargaHuntress Jun 5 '13 at 17:28

  • \$\begingroup\$ Right. I am also worried if anyone faced any problems which appeared later. On cocos-2dx which is also multiplatform, some hardware features on Android I have to code from scratch. Such feature on iOS, I am unable to code thus unable to port my app to iOS. I was wondering if anyone faces such problems with unity port to iOS. \$\endgroup\$ – jackwyn Jun 5 '13 at 17:45

    \$\begingroup\$ First, you'd probably have MUCH better luck asking this over at Unity Answers. Second, if you want to develop for iOS successfully, you will need to test on a physical device...which requires an iOS license for Unity. \$\endgroup\$ – XNargaHuntress Jun 5 '13 at 17:52

    \$\begingroup\$ @XGundam05 while Unity has their own Q & A, the quality there is awful, the software it runs on is awful, and everything there is just.. awful. \$\endgroup\$ – tomsseisums Jun 5 '13 at 19:34

Unity compiles your app into a bunch of assembly code with a thin Objective-C layer around it for OS calls and such. Assuming you're not doing any plugin work (e.g. needing to call OS level features for things) you can publish your game without any working knowledge of Objective C. Even if you do need OS level features, there's usually a plugin available that abstracts most of that stuff away for you.

However in my experience getting an the provisioning profile information set up and actually working is probably going to take you longer than learning Objective C anyway. It's usually a pain to get everything set up properly.
