iPhone Testing – Why Test iPhone Apps on Actual Devices

Mac OS X can only contractually be run on Apple Hardware. iOS requires the Cocoa framework and to have access to a Mac to sign the keychain. While you can use Objective-C on Linux using the OpenStep libraries, you can't push the applications you develop to iOS due to the lack of the correct Cocoa API libraries and while you can push to a jailbroken device without keychaining with a full developer account, in order to sell said app or even to have the public download it, you have play by Apple's rules.

Hi I have been in iOS development since last 2 years.

Answer:

1) No this is not at all true. In fact it is better to build a Universal app rather than separate iPhone and iPad versions of the App. As such if there is not much difference in iPhone and iPad version of the application functionality-wise, then it is better that we make a universal app. It saves a lot of effort and time and also it is convenient for the end users as most of them would want to buy one app and use it on their multiple iDevices.

2) Also one more point from programmer's perspective is that it is very much easier when the client wants updates in the application once it is released as we as programmers have to make changes in the same application rather than two parallel applications.

Conclusion:

So overall, I would say that Universal apps are "better" than separate versions of the app and also there is no extra problems faced when new iOS version is out.

Hope this helps you.
