The main thing is that i have to make compatible it with latest IOS.So, I just want to know

• whether i need to install latest xcode sdk for that ? or
• i can make it with sdk lower than latest?

Answer 1

The only reason you would need to use the latest SDK would be to take advantage of the latest iOS 5 changes (new API's and features like Storyboarding).

But anything that is built under older SDK's (such as iOS 4.3) is supposed to run just fine on iOS 5. In reality, that isn't always the case though.
